The definitive treatment for people with HIV is to be given anti-retroviral drugs. In addition, if already dangerous complications occur, of course the treatment also needs to be adjusted to the types of complications that occur. Often, doctors will coordinate across specialties, such as internal, pulmonary, cardiovascular, and so on in providing patients with appropriate treatment. In terminal cases, where it is felt that the potential for successful treatment is very small, palliative therapy can also be given to improve the quality of the patient's remaining life.
