Fosamprenavir (brand name Lexiva) is an anti-HIV drug belonging to the class of HIV protease inhibitors. It is used to treat HIV-1 infection in adults and children as part of a combination HIV treatment plan. Fosamprenavir works by preventing HIV from multiplying and spreading in the body, allowing the immune system to fight off the infection. Common side effects include nausea, vomiting, diarrhea, headache, and dizziness.
Fosamprenavir is a medication used, along with other medications, to treat human immunodeficiency virus (HIV) infection. It is a prodrug of amprenavir, which is an inhibitor of HIV protease, an enzyme needed by the virus to replicate.
Fosamprenavir was previously a more commonly used medication for HIV, but it is not recommended as a first-line treatment anymore. There are newer medications with fewer side effects and that require less frequent dosing. However, fosamprenavir may still be an option for some people who cannot tolerate other medications.
