Darunavir (darunavir) — Uses, Dosage, Side Effects & Safety

Drug class: HIV-1 Protease Inhibitor

Overview

Darunavir is an antiretroviral medication used to treat human immunodeficiency virus type 1 (HIV-1) infection in adults and children aged 3 years and older. It is always used in combination with other HIV medicines, most commonly with a boosting agent such as ritonavir or cobicistat. Darunavir works by blocking the action of the HIV-1 protease enzyme, which the virus needs to multiply. By inhibiting this enzyme, darunavir helps to lower the amount of HIV in the blood (viral load) and increase the number of CD4 (T) cells, supporting the immune system. Key points for patients: Darunavir does not cure HIV or AIDS, but it helps manage the infection and reduces the risk of complications. It is important to take darunavir exactly as prescribed and not to miss doses, as this can lead to drug resistance. Always use darunavir in combination with other antiretroviral drugs.
