Ritonavir

Ritonavir ( rit-ON-uh-veer) is used, alone or in combination with other medicines, in the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS). Ritonavir will not cure or prevent HIV infection or AIDS; however, it helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay the development of problems usually related to AIDS or HIV disease. Ritonavir will not keep you from spreading HIV to other people. People who receive Ritonavir may continue to have other problems usually related to AIDS or HIV disease. Ritonavir is available only with your doctor's prescription, in the following dosage forms: Oral Capsules (U.S. and Canada) Oral solution (U.S. and Canada)

Ritonavir is used to treat human immunodeficiency virus (HIV) infection. It belongs to a class of drugs called protease (pro' tee ace) inhibitors, which slow the spread of HIV infection in the body.

Ritonavir is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
