FDA Approves Abbott's Norvir

Norvir (ritonavir) is an antiviral medication that prevents human immunodeficiency virus (HIV) cells from multiplying in your body.

Ritonavir prevents human immunodeficiency virus (HIV) cells from multiplying in your body.

Norvir is used to treat HIV, which causes acquired immunodeficiency syndrome (AIDS). Norvir is not a cure for HIV or AIDS.

Norvir is an HIV medication. It is in a category of HIV medications called protease inhibitors (PIs). Norvir prevents CD4 cells that have been infected with HIV from producing new HIV.

Norvir is manufactured by Abbott Laboratories. The U.S. Food and Drug Administration (FDA) approved it for the treatment of HIV infection in 1996.

Norvir is one of the two drugs in Kaletra. Kaletra contains the protease inhibitor lopinavir and small amounts of Norvir.

This drug, used in combination with at least 2 other medications, is used to help treat your HIV infection, thereby improving your quality of life. It also lowers your risk of getting HIV complications (such as new infections, cancer). Ritonavir belongs to a class of drugs known as protease inhibitors.

Ritonavir is not a cure for HIV. It does not prevent the spread of HIV to others through sexual contact or blood contamination (such as sharing used needles).

Usual Dosage:

Norvir is used to boost the effect of other protease inhibitors. The common dosage is usually 100mg to 200mg per day in a single dose or in divided doses. Norvir is no longer used as the lone protease inhibitor in any HIV medication regimen.


Take with meals, preferably a high fat meal. Capsules need to be refrigerated. Take along with the protease inhibitor that Norvir is boosting.
