Fosamprenavir (fosamprenavir calcium) — Uses, Dosage, Side Effects & Safety

Drug class: Antiretroviral, Protease Inhibitor

Overview

Fosamprenavir is an antiretroviral medication used to treat HIV-1 infection in adults and children. It is usually prescribed as part of combination therapy with other HIV medicines. Fosamprenavir helps lower the amount of HIV in your body, which can improve immune function and reduce the risk of developing HIV-related complications. This medicine works by blocking the action of an enzyme called HIV protease, which the virus needs to multiply. By interfering with this enzyme, fosamprenavir helps prevent the virus from making new copies of itself. Key points to remember: Fosamprenavir does not cure HIV or AIDS, but it helps manage the infection. You should take it exactly as prescribed and continue other HIV medications as directed. Do not share your medication with others, and keep regular appointments with your healthcare provider for monitoring.
