Norvir (ritonavir) is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body.
Norvir is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS).
Norvir is not a cure for HIV or AIDS.
Serious drug interactions can occur when certain medicines are used with Norvir. Tell your doctor about all your current medicines and any you start or stop using.
Taking Norvir will not prevent you from passing HIV to other people. Avoid having unprotected sex or sharing razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person. HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Do not change your doses or medication schedule without your doctor’s advice. Every person with HIV or AIDS should remain under the care of a doctor.
