Atazanavir

Atazanavir is an antiviral medicine used in the treatment of HIV (Human Immunodeficiency Virus) infection. It belongs to a group of medicines called protease inhibitors, which help control HIV by stopping the virus from multiplying in the body. By reducing the amount of virus in the blood, Atazanavir helps protect the immune system and lowers the risk of HIV-related infections and complications.

Atazanavir is usually taken in combination with other antiretroviral medicines as part of HIV combination therapy. It does not cure HIV, but when taken regularly as prescribed, it helps people with HIV live longer, healthier, and more active lives. This medicine also helps reduce the chance of transmitting the virus to others.

Atazanavir is taken under strict medical supervision, often once daily, and regular monitoring is required. When used correctly, Atazanavir is a reliable and effective option in long-term HIV management and immune health support.
