Retrovir is used to treat HIV infection as part of antiviral therapy. The drug helps reduce the amount of virus in the body, which supports the immune system and reduces the risk of complications associated with the virus.
Retrovir is also used to prevent transmission of the virus from a pregnant mother to her fetus during pregnancy or childbirth. In addition to being used as part of preventive treatment after possible exposure to the virus, the drug must be used under medical supervision and within a comprehensive treatment plan.
