Fosamprenavir is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children 4 weeks of age and older. Fosamprenavir is always used in combination with other anti-HIV medicines.
Fosamprenavir is a type of anti-HIV medicine called a protease inhibitor (PI). Fosamprenavir works by blocking protease, an HIV enzyme. This prevents HIV from replicating and lowers the amount of HIV in the blood.
Fosamprenavir does not cure HIV/AIDS. It is not known if fosamprenavir reduces the risk of passing HIV to other people.
Before taking fosamprenavir, tell your health care provider:

If your child vomits within 30 minutes after taking a dose of fosamprenavir, the dose should be repeated. Shake the oral suspension vigorously before each use.
Always take fosamprenavir in combination with other anti-HIV medicines.
If you take too much fosamprenavir, contact your local poison control center (1-800-222-1222) or go to the nearest hospital emergency room right away.
