The following serious adverse drug reactions are discussed in other sections of the labeling: Embryo-Fetal Toxicity [see Warnings and Precautions ( 5.1 )] Anemia [see Warnings and Precautions ( 5.2 )] Pancreatitis [see Warnings and Precautions ( 5.3 )] Pulmonary Disorders [see Warnings and Precautions ( 5.4 )] Ophthalmic Disorders [see Warnings and Precautions ( 5.5 )] Dental and Periodontal Disorders [see Warnings and Precautions ( 5.7 )] Impact on Growth in Pediatric Patients [see Warnings and Precautions ( 5.9 )] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Clinical trials with ribavirin in combination with PegIntron or INTRON A have been conducted in over 7,800 subjects from 3 to 76 years of age. The primary toxicity of ribavirin is hemolytic anemia. Reductions in hemoglobin levels occurred within the first 1 to 2 weeks of oral therapy. Cardiac and pulmonary reactions associated with anemia occurred in approximately 10% of patients [see Warnings and Precautions ( 5.2 ) ]. Greater than 96% of all subjects in clinical trials experienced one or more adverse reactions. The most commonly reported adverse reactions in adult subjects receiving PegIntron or INTRON A in combination with ribavirin were injection site inflammation/reaction, fatigue/asthenia, headache, rigors, fevers, nausea, myalgia and anxiety/emotional lability/irritability. The most common adverse reactions in pediatric subjects, ages 3 and older, receiving ribavirin in combination with PegIntron or INTRON A were pyrexia, headache, neutropenia, fatigue, anorexia, injection site erythema, and vomiting. The Adverse Reactions section references the following clinical trials: Ribavirin /PegIntron combination therapy trials: Clinical Study 1–evaluated PegIntron monotherapy (not further described in this label; see labeling for PegIntron for information about this trial). Study 2–evaluated ribavirin 800 mg/day flat dose in combination with 1.5 mcg/kg/week PegIntron or with INTRON A. Study 3–evaluated PegIntron/weight-based ribavirin in combination with PegIntron/flat dose ribavirin regimen. Study 4–compared two PegIntron (1.5 mcg/kg/week and 1 mcg/kg/week) doses in combination with ribavirin and a third treatment group receiving Pegasys ® (180 mcg/week)/Copegus ® (1,000 to 1,200 mg/day). Study 5–evaluated PegIntron (1.5 mcg/kg/week) in combination with weight-based ribavirin in prior treatment failure subjects. PegIntron/ribavirin combination therapy in Pediatric Patients Ribavirin/INTRON A combination therapy trials for adults and pediatrics Serious adverse reactions have occurred in approximately 12% of subjects in clinical trials with PegIntron with or without ribavirin [see Boxed Warning, Warnings and Precautions ( 5 )] . The most common serious events occurring in subjects treated with PegIntron and ribavirin were depression and suicidal ideation [see Warnings and Precautions ( 5.10 )] , each occurring at a frequency of less than 1%. Suicidal ideation or attempts occurred more frequently among pediatric patients, primarily adolescents, compared to adult patients (2.4% versus 1%) during treatment and off-therapy follow-up [see Warnings and Precautions ( 5.10 )] . The most common fatal reaction occurring in subjects treated with PegIntron and ribavirin was cardiac arrest, suicidal ideation, and suicide attempt [see Warnings and Precautions ( 5.10 )] , all occurring in less than 1% of subjects.

In Study 2, the incidence of serious adverse reactions was 17% in the PegIntron/ ribavirin groups compared to 14% in the INTRON A/ ribavirin group. In Study 3, there was a similar incidence of serious adverse reactions reported for the weight-based ribavirin group (12%) and for the flat-dose ribavirin regimen. In many but not all cases, adverse reactions resolved after dose reduction or discontinuation of therapy. Some subjects experienced ongoing or new serious adverse reactions during the 6-month follow-up period. In Study 2, many subjects continued to experience adverse reactions several months after discontinuation of therapy. By the end of the 6-month follow-up period, the incidence of ongoing adverse reactions by body class in the PegIntron 1.5 mcg/ ribavirin group was 33% (psychiatric), 20% (musculoskeletal), and 10% (for endocrine and for GI). In approximately 10 to 15% of subjects, weight loss, fatigue, and headache had not resolved. There have been 28 subject deaths that occurred during treatment or follow-up in Studies 2, 3, and 4. In Study 2, there was 1 suicide in a subject receiving PegIntron/ribavirin combination therapy; and 1 subject death in the INTRON A/ribavirin group (motor vehicle accident). In Study 3, there were 14 deaths, 2 of which were probable suicides and 1 was an unexplained death in a person with a relevant medical history of depression. In Study 4, there were 12 deaths, 6 of which occurred in subjects who received PegIntron/ribavirin combination therapy, 5 in the PegIntron 1.5 mcg/ ribavirin arm (N=1,019) and 1 in the PegIntron 1 mcg/ribavirin arm (N=1,016), and 6 of which occurred in subjects receiving Pegasys/Copegus (N=1,035); there were 3 suicides that occurred during the off treatment follow-up period in subjects who received PegIntron (1.5 mcg/kg)/ribavirin combination therapy. In Studies 1 and 2, 10 to 14% of subjects receiving PegIntron, alone or in combination with ribavirin, discontinued therapy compared with 6% treated with INTRON A alone and 13% treated with INTRON A in combination with ribavirin. In Study 3, 15% of subjects receiving PegIntron in combination with weight-based ribavirin and 14% of subjects receiving PegIntron with flat dose ribavirin discontinued therapy due to an adverse reaction. The most common reasons for discontinuation were related to known interferon effects of psychiatric, systemic (e.g., fatigue, headache), or gastrointestinal adverse reactions. In Study 4, 13% of subjects in the PegIntron 1.5 mcg/ribavirin arm, 10% in the PegIntron 1 mcg/ribavirin arm and 13% in the Pegasys 180 mcg/Copegus arm discontinued due to adverse events. In Study 2, dose reductions for ribavirin were similar across all three groups [see Clinical Studies ( 14.1 )] , 33 to 35%. The most common reasons for dose modifications were neutropenia (18%), or anemia (9%) (see Laboratory Values ). Other common reasons included depression, fatigue, nausea, and thrombocytopenia. In Study 3, dose modifications due to adverse reactions occurred more frequently with weight-based ribavirin dosing compared to flat dosing (29% and 23%, respectively). In Study 4, 16% of subjects had a dose reduction of PegIntron to 1 mcg/kg in combination with ribavirin, with an additional 4% requiring the second dose reduction of PegIntron to 0.5 mcg/kg due to adverse events compared to 15% of subjects in the Pegasys/Copegus arm, who required a dose reduction to 135 mcg/week with Pegasys, with an additional 7% in the Pegasys/Copegus arm requiring second dose reduction to 90 mcg/week with Pegasys. In the PegIntron/ribavirin combination trials the most common adverse reactions were psychiatric, which occurred among 77% of subjects in Study 2 and 68% to 69% of subjects in Study 3. These psychiatric adverse reactions included most commonly depression, irritability, and insomnia, each reported by approximately 30% to 40% of subjects in all treatment groups. Suicidal behavior (ideation, attempts, and suicides) occurred in 2% of all subjects during treatment or during follow-up after treatment cessation [see Warnings and Precautions ( 5 )] . In Study 4, psychiatric adverse reactions occurred in 58% of subjects in the PegIntron 1.5 mcg/ribavirin arm, 55% of subjects in the PegIntron 1 mcg/ribavirin arm, and 57% of subjects in the Pegasys 180 mcg/Copegus arm. In Study 2, PegIntron/ribavirin combination therapy induced fatigue or headache in approximately two-thirds of subjects, with fever or rigors in approximately half of the subjects. The severity of some of these systemic symptoms (e.g., fever and headache) tended to decrease as treatment continued. Subjects receiving ribavirin/PegIntron as re-treatment after failing a previous interferon combination regimen reported adverse reactions similar to those previously associated with this regimen during clinical trials of treatment-naïve subjects. Pediatric Subjects In general, the adverse reaction profile in the pediatric population was similar to that observed in adults. In the pediatric trial, the most prevalent adverse reactions were pyrexia (80%), headache (62%), neutropenia (33%), fatigue (30%), anorexia (29%), injection-site erythema (29%) and vomiting (27%). The majority of adverse reactions were mild or moderate in severity. Severe adverse reactions were reported in 7% (8/107) of all subjects and included injection site pain (1%), pain in extremity (1%), headache (1%), neutropenia (1%), and pyrexia (4%). Important adverse reactions that occurred in this subject population were nervousness (7%; 7/107), aggression (3%; 3/107), anger (2%; 2/107), and depression (1%; 1/107). Five subjects received levothyroxine treatment, three with clinical hypothyroidism and two with asymptomatic TSH elevations. Weight and height gain of pediatric subjects treated with PegIntron plus ribavirin lagged behind that predicted by normative population data for the entire length of treatment. Severely inhibited growth velocity (less than 3rd percentile) was observed in 70% of the subjects while on treatment. Dose modifications of PegIntron and/or ribavirin were required in 25% of subjects due to treatment-related adverse reactions, most commonly for anemia, neutropenia and weight loss. Two subjects (2%; 2/107) discontinued therapy as the result of an adverse reaction. Adverse reactions that occurred with a greater than or equal to 10% incidence in the pediatric trial subjects are provided in Table 7 .

The long-term effects on growth were less in subjects treated for 24 weeks than in those treated for 48 weeks. Twenty-four percent of subjects (11/46) treated for 24 weeks and 40% of subjects (19/48) treated for 48 weeks had a >15 percentile height-for-age decrease from pre-treatment baseline to the end of 5-year follow-up. Eleven percent of subjects (5/46) treated for 24 weeks and 13% of subjects (6/48) treated for 48 weeks had a >30 percentile height-for-age decrease from pre-treatment baseline to the end of the 5-year follow-up. While observed across all age groups, the highest risk for reduced height at the end of long-term follow-up appeared to be initiation of combination therapy during the years of expected peak growth velocity [see Warnings and Precautions ( 5.9 )] . Laboratory Values Adult and Pediatric Subjects The adverse reaction profile in Study 3, which compared PegIntron/weight-based ribavirin combination to a PegIntron/flat dose ribavirin regimen, revealed an increased rate of anemia with weight-based dosing (29% vs. 19% for weight-based vs. flat dose regimens, respectively). However, the majority of cases of anemia were mild and responded to dose reductions. Changes in selected laboratory values during treatment in combination with ribavirin treatment are described below. Decreases in hemoglobin, leukocytes, neutrophils, and platelets may require dose reduction or permanent discontinuation from therapy [see Dosage and Administration ( 2.5 )] . Changes in selected laboratory values during therapy are described in Table 8 . Most of the changes in laboratory values in the PegIntron/ribavirin trial with pediatrics were mild or moderate.

In Study 2, hemoglobin levels decreased to less than 11 g/dL in about 30% of subjects. In Study 3, 47% of subjects receiving weight-based dosing of ribavirin and 33% on flat-dose ribavirin had decreases in hemoglobin levels to less than 11 g/dL. Reductions in hemoglobin to less than 9 g/dL occurred more frequently in subjects receiving weight-based dosing compared to flat dosing (4% and 2%, respectively). In Study 2, dose modification was required in 9% and 13% of subjects in the PegIntron/ribavirin and INTRON A/ribavirin groups. In Study 4, subjects receiving PegIntron (1.5 mcg/kg)/ribavirin had decreases in hemoglobin levels to between 8.5 to less than 10 g/dL (28%) and to less than 8.5 g/dL (3%), whereas in patients receiving Pegasys 180 mcg/Copegus these decreases occurred in 26% and 4% of subjects, respectively. On average, hemoglobin levels became stable by treatment weeks 4 to 6. The typical pattern observed was a decrease in hemoglobin levels by treatment week 4 followed by stabilization and a plateau, which was maintained to the end of treatment [see Dosage and Administration ( 2.5 )] . Neutrophils. In Study 2, decreases in neutrophil counts were observed in a majority of adult subjects treated with PegIntron/ribavirin (85%) and INTRON A/ribavirin (60%). Severe, potentially life-threatening neutropenia (less than 0.5 x 109/L) occurred in approximately 4% of subjects treated with PegIntron/ribavirin and 2% of subjects treated with INTRON A/ribavirin. Eighteen percent of subjects receiving PegIntron/ribavirin required modification of interferon dosage. Few subjects (less than 1%) required permanent discontinuation of treatment. Neutrophil counts generally returned to pre-treatment levels 4 weeks after cessation of therapy [see Dosage and Administration ( 2.5 )] . Platelets. In Study 2, platelet counts decreased to less than 100,000/mm 3 in approximately 20% of subjects treated with PegIntron alone or with ribavirin and in 6% of adult subjects treated with INTRON A/ribavirin. Severe decreases in platelet counts (less than 50,000/mm 3 ) occur in less than 4% of adult subjects. In Study 2, 1% or 3% of subjects required dose modification of INTRON A or PegIntron, respectively. Platelet counts generally returned to pretreatment levels 4 weeks after the cessation of therapy [see Dosage and Administration ( 2.5 )] . Thyroid Function. In Study 2, clinically apparent thyroid disorders occurred among subjects treated with either INTRON A or PegIntron (with or without ribavirin) at a similar incidence (5% for hypothyroidism and 3% for hyperthyroidism). Subjects developed new onset TSH abnormalities while on treatment and during the follow-up period. At the end of the follow-up period, 7% of subjects still had abnormal TSH values. Bilirubin and Uric Acid. In Study 2, 10 to 14% of subjects developed hyperbilirubinemia and 33 to 38% developed hyperuricemia in association with hemolysis. Six subjects developed mild to moderate gout. Adverse Reactions with ribavirin/INTRON A Combination Therapy Adult Subjects In clinical trials, 19% and 6% of previously untreated and relapse subjects, respectively, discontinued therapy due to adverse reactions in the combination arms compared to 13% and 3% in the interferon-only arms. Selected treatment-related adverse reactions that occurred in the US trials with incidence 5% or greater are provided by treatment group (see Table 9 ). In general, the selected treatment-related adverse reactions were reported with lower incidence in the international trials as compared to the US trials, except for asthenia, influenza-like symptoms, nervousness, and pruritus. Pediatric Subjects In clinical trials of 118 pediatric subjects 3 to 16 years of age, 6% discontinued therapy due to adverse reactions. Dose modifications were required in 30% of subjects, most commonly for anemia and neutropenia. In general, the adverse-reaction profile in the pediatric population was similar to that observed in adults. Injection site disorders, fever, anorexia, vomiting, and emotional lability occurred more frequently in pediatric subjects compared to adult subjects. Conversely, pediatric subjects experienced less fatigue, dyspepsia, arthralgia, insomnia, irritability, impaired concentration, dyspnea, and pruritus compared to adult subjects. Selected treatment-related adverse reactions that occurred with incidence 5% or greater among all pediatric subjects who received the recommended dose of ribavirin/INTRON A combination therapy are provided in Table 9.

A general reversal of these trends was noted during the 24-week post-treatment period. Long-term data in a limited number of patients, however, suggests that combination therapy may induce a growth inhibition that results in reduced final adult height in some patients [see Warnings and Precautions ( 5.9 )]. Laboratory Values Changes in selected hematologic values (hemoglobin, white blood cells, neutrophils, and platelets) during therapy are described below (see Table 10) . Hemoglobin. Hemoglobin decreases among subjects receiving ribavirin therapy began at Week 1, with stabilization by Week 4. In previously untreated subjects treated for 48 weeks, the mean maximum decrease from baseline was 3.1 g/dL in the US trial and 2.9 g/dL in the international trial. In relapse subjects, the mean maximum decrease from baseline was 2.8 g/dL in the US trial and 2.6 g/dL in the international trial. Hemoglobin values returned to pretreatment levels within 4 to 8 weeks of cessation of therapy in most subjects. Bilirubin and Uric Acid . Increases in both bilirubin and uric acid, associated with hemolysis, were noted in clinical trials. Most changes were moderate and reversed within 4 weeks after treatment discontinuation. This observation occurred most frequently in subjects with a previous diagnosis of Gilbert\'s syndrome. This has not been associated with hepatic dysfunction or clinical morbidity.

Discontinue nucleoside reverse transcriptase inhibitors or reduce dose or discontinue interferon, ribavirin or both with worsening toxicities. ( 7.2 ) 7.1 Didanosine Exposure to didanosine or its active metabolite (dideoxyadenosine 5\'-triphosphate) is increased when didanosine is coadministered with ribavirin, which could cause or worsen clinical toxicities; therefore, coadministration of ribavirin capsules and didanosine is contraindicated [see Contraindications ( 4 )] . Reports of fatal hepatic failure, as well as peripheral neuropathy, pancreatitis, and symptomatic hyperlactatemia/lactic acidosis have been reported in clinical trials. 7.2 Nucleoside Analogues Hepatic decompensation (some fatal) has occurred in cirrhotic HIV/HCV co-infected patients receiving combination antiretroviral therapy for HIV and interferon alpha and ribavirin. Patients receiving interferon with ribavirin and nucleoside reverse transcriptase inhibitors (NRTIs) should be closely monitored for treatment- associated toxicities, especially hepatic decompensation and anemia. Discontinuation of NRTIs should be considered as medically appropriate [see labeling for individual NRTI product ]. Dose reduction or discontinuation of interferon, ribavirin, or both should also be considered if worsening clinical toxicities are observed, including hepatic decompensation (e.g., Child-Pugh greater than 6). Ribavirin may antagonize the cell culture antiviral activity of stavudine and zidovudine against HIV. Ribavirin has been shown in cell culture to inhibit phosphorylation of lamivudine, stavudine and zidovudine, which could lead to decreased antiretroviral activity. However, in a study with another pegylated interferon in combination with ribavirin, no pharmacokinetic (e.g., plasma concentrations or intracellular triphosphorylated active metabolite concentrations) or pharmacodynamic (e.g., loss of HIV/HCV virologic suppress) interaction was observed when ribavirin and lamivudine (n=18), stavudine (n=10), or zidovudine (n=6) were coadministered as part of a multidrug regimen in HIV/HCV co-infected subjects. Concomitant use of ribavirin with any of these drugs should be done with caution. 7.3 Drugs Metabolized by Cytochrome P-450 Results of in vitro studies using both human and rat liver microsome preparations indicated little or no cytochrome P-450 enzyme-mediated metabolism of ribavirin, with minimal potential for P-450 enzyme-based drug interactions. No pharmacokinetic interactions were noted between INTRON A and ribavirin capsules in a multiple-dose pharmacokinetic study. 7.4 Azathioprine The use of ribavirin for the treatment of chronic hepatitis C in patients receiving azathioprine has been reported to induce severe pancytopenia and may increase the risk of azathioprine-related myelotoxicity. Inosine monophosphate dehydrogenase (IMDH) is required for one of the metabolic pathways of azathioprine. Ribavirin is known to inhibit IMDH, thereby leading to accumulation of an azathioprine metabolite, 6-methylthioinosine monophosphate (6-MTITP), which is associated with myelotoxicity (neutropenia, thrombocytopenia, and anemia). Patients receiving azathioprine with ribavirin should have complete blood counts, including platelet counts, monitored weekly for the first month, twice monthly for the second and third months of treatment, then monthly or more frequently if dosage or other therapy changes are necessary [see Warnings and Precautions ( 5.8 ) ]."}', 'indications_and_usage': '{"1 INDICATIONS AND USAGE Ribavirin is a nucleoside analogue indicated in combination with interferon alfa- 2b (pegylated and nonpegylated) for the treatment of Chronic Hepatitis C (CHC) in patients 3 years of age or older with compensated liver disease.

The following points should be considered when initiating ribavirin capsules combination therapy with PegIntron ® or INTRON A ® : Combination therapy with ribavirin /PegIntron is preferred over ribavirin /INTRON A as this combination provides substantially better response rates [see Clinical Studies ( 14 ) ]. Patients with the following characteristics are less likely to benefit from retreatment after failing a course of therapy: previous nonresponse, previous pegylated interferon treatment, significant bridging fibrosis or cirrhosis, and genotype 1 infection [see Clinical Studies ( 14 ) ].

Patients should have a negative pregnancy test prior to therapy and use effective contraception and undergo periodic pregnancy tests. ( 5.1 , 8.1 , 8.3 ) Patients exhibiting the following conditions should be closely monitored and may require dose reduction or discontinuation of therapy: Hemolytic anemia may occur with a significant initial drop in hemoglobin. ( 5.2 ) Pancreatitis. ( 5.3 ) Pulmonary infiltrates or pulmonary function impairment. ( 5.4 ) New or worsening ophthalmologic disorders ( 5.5 ) Severe decreases in neutrophil and platelet counts, and hematologic, endocrine (e.g., TSH), and hepatic abnormalities. ( 5.6 ) Dental/periodontal disorders reported with combination therapy. ( 5.7 ) Concomitant administration of azathioprine. ( 5.8 ) Weight loss and growth inhibition reported during combination therapy in pediatric patients. Long-term growth inhibition (height) reported in some patients. ( 5.9 ) Monotherapy with ribavirin is not permitted. ( 5.10 ) 5.1 Embryo-Fetal Toxicity Ribavirin capsules and oral solution may cause birth defects, miscarriage or stillbirth. Ribavirin therapy should not be started until a report of a negative pregnancy test has been obtained immediately prior to planned initiation of therapy. Patients should use effective contraception and have periodic monitoring with pregnancy tests during treatment and during the 6-month period after treatment has been stopped. Extreme care must be taken to avoid pregnancy in female patients and in female partners of male patients. Ribavirin has demonstrated significant teratogenic and embryocidal effects in all animal species tested. These effects occurred at doses as low as one twentieth of the recommended human dose of ribavirin [see Boxed Warning, Contraindications ( 4 ), and Use in Specific Populations ( 8.1 , 8.3 )] . 5.2 Anemia Hemolytic anemia was observed in approximately 10% of ribavirin/INTRON A-treated subjects in clinical trials. The anemia associated with ribavirin occurs within 1 to 2 weeks of initiation of therapy. Because the initial drop in hemoglobin may be significant, obtain hemoglobin or hematocrit levels before the start of treatment and at week 2 and week 4 of therapy, or more frequently if clinically indicated. Patients should then be followed as clinically appropriate [see Dosage and Administration ( 2.5 , 2.6 )] . Fatal and nonfatal myocardial infarctions have been reported in patients with anemia caused by ribavirin. Patients should be assessed for underlying cardiac disease before initiation of ribavirin therapy. Patients with pre-existing cardiac disease should have electrocardiograms administered before treatment and should be appropriately monitored during therapy. If there is any deterioration of cardiovascular status, therapy should be suspended or discontinued [see Dosage and Administration ( 2.5 , 2.6 )] . Because cardiac disease may be worsened by drug-induced anemia, patients with a history of significant or unstable cardiac disease should not use ribavirin. 5.3 Pancreatitis Suspend ribavirin and INTRON A or PegIntron combination therapy in patients with signs and symptoms of pancreatitis and discontinue in patients with confirmed pancreatitis. 5.4 Pulmonary Disorders Pulmonary symptoms, including dyspnea, pulmonary infiltrates, pneumonitis, pulmonary hypertension, and pneumonia, have been reported during ribavirin with alpha interferon combination therapy; occasional cases of fatal pneumonia have occurred. In addition, sarcoidosis or the exacerbation of sarcoidosis has been reported. If there is evidence of pulmonary infiltrates or pulmonary function impairment, closely monitor the patient, and if appropriate, discontinue combination therapy. 5.5 Ophthalmologic Disorders Ribavirin is used in combination therapy with INTRON A or PegIntron. Refer to labeling for PegIntron for additional information. 5.6 Laboratory Tests PegIntron in combination with ribavirin may cause severe decreases in neutrophil and platelet counts, and hematologic, endocrine (e.g., TSH), and hepatic abnormalities. Obtain hematology and blood chemistry testing in patients on PegIntron/ribavirin combination therapy before the start of treatment and then periodically thereafter. In the adult clinical trial, complete blood counts (including hemoglobin, neutrophil, and platelet counts) and chemistries (including AST, ALT, bilirubin, and uric acid) were measured during the treatment period at weeks 2, 4, 8, 12, and then at 6-week intervals, or more frequently if abnormalities developed. In pediatric subjects, the same laboratory parameters were evaluated with additional assessment of hemoglobin at treatment week 6. TSH levels were measured every 12 weeks during the treatment period. HCV-RNA should be measured periodically during treatment [see Dosage and Administration ( 2 ) ]. 5.7 Dental and Periodontal Disorders Dental and periodontal disorders have been reported in patients receiving ribavirin and interferon or peginterferon combination therapy. In addition, dry mouth could have a damaging effect on teeth and mucous membranes of the mouth during long-term treatment with the combination of ribavirin and pegylated or nonpegylated interferon alfa-2b. Advise patients to brush their teeth thoroughly twice daily and have regular dental examinations. If vomiting occurs, advise patients to rinse out their mouth thoroughly afterwards. 5.8 Concomitant Administration of Azathioprine Pancytopenia (marked decreases in red blood cells, neutrophils, and platelets) and bone marrow suppression have been reported in the literature to occur within 3 to 7 weeks after the concomitant administration of pegylated interferon/ribavirin and azathioprine. In this limited number of patients (n=8), myelotoxicity was reversible within 4 to 6 weeks upon withdrawal of both HCV antiviral therapy and concomitant azathioprine and did not recur upon reintroduction of either treatment alone. Discontinue PegIntron, ribavirin, and azathioprine for pancytopenia, and do not reintroduce pegylated interferon/ribavirin with concomitant azathioprine [see Drug Interactions ( 7.4 )] . 5.9 Impact on Growth in Pediatric Patients Data on the effects of PegIntron and ribavirin on growth come from an open-label study in subjects 3 through 17 years of age, in which weight and height changes were compared to US normative population data. In general, the weight and height gain of pediatric subjects treated with PegIntron and ribavirin lagged behind that predicted by normative population data for the entire length of treatment. Severely inhibited growth velocity (less than 3 rd percentile) was observed in 70% of the subjects while on treatment. Following treatment, rebound growth and weight gain occurred in most subjects. Long-term follow-up data in pediatric subjects, however, indicates that PegIntron in combination therapy with ribavirin may induce a growth inhibition that results in reduced adult height in some patients [see Adverse Reactions ( 6.1 )]. Similarly, an impact on growth was seen in subjects after treatment with ribavirin and INTRON A combination therapy for one year. In a long-term follow-up trial of a limited number of these subjects, combination therapy resulted in reduced final adult height in some subjects [see Adverse Reactions ( 6.1 ) ]. 5.10 Not Recommended for Monotherapy and Risks Associated with Combination Therapy Based on results of clinical trials, ribavirin monotherapy is not effective for the treatment of chronic hepatitis C virus infection; therefore, ribavirin capsules must not be used alone. The safety and efficacy of ribavirin capsules have only been established when used together with INTRON A or PegIntron (not other interferons) as combination therapy. The safety and efficacy of ribavirin with INTRON A or PegIntron combination therapy for the treatment of HIV infection, adenovirus, RSV, parainfluenza, or influenza infections have not been established. Ribavirin capsules should not be used for these indications. There are significant adverse reactions caused by ribavirin/INTRON A or PegIntron combination therapy, including severe depression and suicidal or homicidal ideation, hemolytic anemia, suppression of bone marrow function, autoimmune and infectious disorders, pulmonary dysfunction, pancreatitis, and diabetes. Suicidal ideation or attempts occurred more frequently among pediatric patients, primarily adolescents, compared to adult patients (2.4% versus 1%) during treatment and off-therapy follow-up. Labeling for INTRON A and PegIntron should be reviewed in their entirety for additional safety information prior to initiation of combination treatment."}', 'overdosage': '{"10 OVERDOSAGE There is limited experience with overdosage. Acute ingestion of up to 20 g of ribavirin capsules, INTRON A ingestion of up to 120 million units, and subcutaneous doses of INTRON A up to 10 times the recommended doses have been reported. Primary effects that have been observed are increased incidence and severity of the adverse reactions related to the therapeutic use of INTRON A and ribavirin capsules. However, hepatic enzyme abnormalities, renal failure, hemorrhage, and myocardial infarction have been reported with administration of single subcutaneous doses of INTRON A that exceed dosing recommendations.

Ribavirin has demonstrated significant teratogenic and embryocidal effects in all animal species tested. These effects occurred at doses as low as one twentieth of the recommended human dose of ribavirin [see Boxed Warning, Contraindications ( 4 ), and Use in Specific Populations ( 8.1 , 8.3 )] .","8.1 Pregnancy Risk Summary Ribavirin is contraindicated for use in pregnant women and in men whose female partners are pregnant [see Contraindications ( 4 )] . Based on animal data, ribavirin use in pregnancy may be associated with birth defects. Data from the Ribavirin Pregnancy Registry are insufficient to identify a drug-associated risk of birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data) . Ribavirin is known to accumulate in intracellular components from where it is cleared very slowly. In animal studies, ribavirin exposure was shown to have teratogenic and/or embryocidal effects (see Data). All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage is 2 to 4% and 15 to 20%, respectively. Data Human Data Available data from the Ribavirin Pregnancy Registry on 88 live births from pregnancies in women directly exposed and 98 live births from pregnancies in women indirectly exposed (by a male partner) to ribavirin during pregnancy or during the 6 months prior to pregnancy show a higher rate of birth defects (9.09% and 6.12%, respectively) compared to a background birth defect rate of 2.72% in the Metropolitan Atlanta Congenital Defects Program (MACDP) birth defects surveillance system. No pattern of birth defects can be identified from these reports. The miscarriage rate was approximately 21%. The current sample size is insufficient for reaching definitive conclusions based on statistical analysis. Trends suggesting a common etiology or relationship with ribavirin exposure were not observed. Methodologic limitations of the Ribavirin Pregnancy Registry include the use of MACDP as the external comparator group. Limitations of using an external comparator include differences in methodology and populations, as well as confounding due to the underlying disease and comorbidities. Animal Data Embryotoxicity/teratogenicity studies with ribavirin were conducted in rats (oral doses of 0.3, 1.0 and 10 mg/kg on Gestation Days 6 to 15) and rabbits (oral dose of 0.1, 0.3 and 1.0 mg/kg on Gestation Days 6 to 18).Ribavirin demonstrated significant embryocidal and teratogenic effects at doses well below the recommended human dose in all animal species in which adequate studies have been conducted. Malformations of the skull, palate, eye, jaw, limbs, skeleton, and gastrointestinal tract were noted. The incidence and severity of teratogenic effects increased with escalation of the drug dose. Survival of fetuses and offspring was reduced [see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 )] ."}', 'pediatric_use': None, 'geriatric_use': '{"8.5 Geriatric Use Clinical trials of ribavirin combination therapy did not include sufficient numbers of subjects aged 65 and over to determine if they respond differently from younger subjects. Ribavirin is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients often have decreased renal function, care should be taken in dose selection. Renal function should be monitored and dosage adjustments made accordingly. Ribavirin should not be used in patients with creatinine clearance less than 50 mL/min [ see Contraindications ( 4 ) ]. In general, ribavirin capsules should be administered to elderly patients cautiously, starting at the lower end of the dosing range, reflecting the greater frequency of decreased hepatic and cardiac function, and of concomitant disease or other drug therapy. In clinical trials, elderly subjects had a higher frequency of anemia (67%) than younger patients (28%) [see Warnings and Precautions ( 5.2 ) ]."}'}

Improvement is manifested by relief of muscle spasm and its associated signs and symptoms, namely, pain, tenderness, limitation of motion, and restriction in activities of daily living. Cyclobenzaprine HCl should be used only for short periods (up to two or three weeks) because adequate evidence of effectiveness for more prolonged use is not available and because muscle spasm associated with acute, painful musculoskeletal conditions is generally of short duration and specific therapy for longer periods is seldom warranted. Cyclobenzaprine HCl has not been found effective in the treatment of spasticity associated with cerebral or spinal cord disease, or in children with cerebral palsy."}', 'warnings_and_cautions': None, 'overdosage': '{"OVERDOSAGE Although rare, deaths may occur from overdosage with cyclobenzaprine HCl. Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose. As management of overdose is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. Signs and symptoms of toxicity may develop rapidly after cyclobenzaprine overdose; therefore, hospital monitoring is required as soon as possible. The acute oral LD 50 of cyclobenzaprine HCl is approximately 338 and 425 mg/kg in mice and rats, respectively. Manifestations The most common effects associated with cyclobenzaprine overdose are drowsiness and tachycardia. Less frequent manifestations include tremor, agitation, coma, ataxia, hypertension, slurred speech, confusion, dizziness, nausea, vomiting, and hallucinations. Rare but potentially critical manifestations of overdose are cardiac arrest, chest pain, cardiac dysrhythmias, severe hypotension, seizures, and neuroleptic malignant syndrome. Changes in the electrocardiogram, particularly in QRS axis or width, are clinically significant indicators of cyclobenzaprine toxicity. Other potential effects of overdosage include any of the symptoms listed under ADVERSE REACTIONS . Management General As management of overdose is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. In order to protect against the rare but potentially critical manifestations described above, obtain an ECG and immediately initiate cardiac monitoring. Protect the patient’s airway, establish an intravenous line and initiate gastric decontamination. Observation with cardiac monitoring and observation for signs of CNS or respiratory depression, hypotension, cardiac dysrhythmias and/or conduction blocks, and seizures is necessary. If signs of toxicity occur at any time during this period, extended monitoring is required. Monitoring of plasma drug levels should not guide management of the patient. Dialysis is probably of no value because of low plasma concentrations of the drug. Gastrointestinal Decontamination All patients suspected of an overdose with cyclobenzaprine HCl should receive gastrointestinal decontamination. This should include large volume gastric lavage followed by activated charcoal. If consciousness is impaired, the airway should be secured prior to lavage and emesis is contraindicated. Cardiovascular A maximal limb-lead QRS duration of ≥0.10 seconds may be the best indication of the severity of the overdose. Serum alkalinization, to a pH of 7.45 to 7.55, using intravenous sodium bicarbonate and hyperventilation (as needed), should be instituted for patients with dysrhythmias and/or QRS widening. A pH > 7.60 or a pCO 2 < 20 mmHg is undesirable. Dysrhythmias unresponsive to sodium bicarbonate therapy/hyperventilation may respond to lidocaine, bretylium or phenytoin. Type 1A and 1C antiarrhythmics are generally contraindicated (e.g., quinidine, disopyramide, and procainamide). CNS In patients with CNS depression, early intubation is advised because of the potential for abrupt deterioration. Seizures should be controlled with benzodiazepines or, if these are ineffective, other anticonvulsants (e.g. phenobarbital, phenytoin). Physostigmine is not recommended except to treat life-threatening symptoms that have been unresponsive to other therapies, and then only in close consultation with a poison control center. Psychiatric Follow-Up Since overdosage is often deliberate, patients may attempt suicide by other means during the recovery phase. Psychiatric referral may be appropriate. Pediatric Management The principles of management of child and adult overdosages are similar. It is strongly recommended that the physician contact the local poison control center for specific pediatric treatment."}', 'active_flag': 'Y', 'generic_name': '{"CYCLOBENZAPRINE HYDROCHLORIDE"}', 'route': '{ORAL}', 'product_type': '{"HUMAN PRESCRIPTION DRUG"}', 'stop_use': None, 'do_not_use': None, 'when_using': None, 'warnings': '{"WARNINGS Serotonin Syndrome The development of a potentially life-threatening serotonin syndrome has been reported with Cyclobenzaprine Hydrochloride when used in combination with other drugs, such as selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), tramadol, bupropion, meperidine, verapamil, or MAO inhibitors. The concomitant use of Cyclobenzaprine Hydrochloride with MAO inhibitors is contraindicated (see CONTRAINDICATIONS ). Serotonin syndrome symptoms may include mental status changes (e.g., confusion, agitation, hallucinations), autonomic instability (e.g., diaphoresis, tachycardia, labile blood pressure, hyperthermia), neuromuscular abnormalities (e.g., tremor, ataxia, hyperreflexia, clonus, muscle rigidity), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Treatment with Cyclobenzaprine Hydrochloride and any concomitant serotonergic agents should be discontinued immediately if the above reactions occur and supportive symptomatic treatment should be initiated. If concomitant treatment with Cyclobenzaprine Hydrochloride and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dose increases (see PRECAUTIONS , Drug Interactions ). Cyclobenzaprine is closely related to the tricyclic antidepressants, e.g., amitriptyline and imipramine. In short term studies for indications other than muscle spasm associated with acute musculoskeletal conditions, and usually at doses somewhat greater than those recommended for skeletal muscle spasm, some of the more serious central nervous system reactions noted with the tricyclic antidepressants have occurred (see WARNINGS , below, and ADVERSE REACTIONS ). Tricyclic antidepressants have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. Cyclobenzaprine HCl may enhance the effects of alcohol, barbiturates, and other CNS depressants."}', 'precautions': '{"PRECAUTIONS General Because of its atropine-like action, cyclobenzaprine HCl should be used with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic medication. Impaired Hepatic Function The plasma concentration of cyclobenzaprine is increased in patients with hepatic impairment (see CLINICAL PHARMACOLOGY, Pharmacokinetics , Hepatic Impairment ). These patients are generally more susceptible to drugs with potentially sedating effects, including cyclobenzaprine. Cyclobenzaprine HCl should be used with caution in subjects with mild hepatic impairment starting with a 5 mg dose and titrating slowly upward. Due to the lack of data in subjects with more severe hepatic insufficiency, the use of cyclobenzaprine HCl in subjects with moderate to severe impairment is not recommended. Information for Patients Cyclobenzaprine HCl, especially when used with alcohol or other CNS depressants, may impair mental and/or physical abilities required for performance of hazardous tasks, such as operating machinery or driving a motor vehicle. In the elderly, the frequency and severity of adverse events associated with the use of cyclobenzaprine, with or without concomitant medications, is increased. In elderly patients, cyclobenzaprine HCl should be initiated with a 5 mg dose and titrated slowly upward. Patients should be cautioned about the risk of serotonin syndrome with the concomitant use of Cyclobenzaprine Hydrochloride and other drugs, such as SSRIs, SNRIs, TCAs, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors.

In the higher dose groups this microscopic change was seen after 26 weeks and even earlier in rats which died prior to 26 weeks; at lower doses, the change was not seen until after 26 weeks. Cyclobenzaprine did not affect the onset, incidence or distribution of neoplasia in an 81-week study in the mouse or in a 105-week study in the rat. At oral doses of up to 10 times the human dose, cyclobenzaprine did not adversely affect the reproductive performance or fertility of male or female rats. Cyclobenzaprine did not demonstrate mutagenic activity in the male mouse at dose levels of up to 20 times the human dose. Pregnancy Reproduction studies have been performed in rats, mice and rabbits at doses up to 20 times the human dose, and have revealed no evidence of impaired fertility or harm to the fetus due to cyclobenzaprine HCl. There are, however, no adequate and well-controlled studies in pregnant women.
