Norvir an oral tablet made up of a protease inhibitor/antiviral booster called ritonavir. We carry both the brand choice and generic alternative of this medication in 100mg!

Norvir is used with other medications to control human immunodeficiency virus (HIV) and preventing acquired immunodeficiency syndrome (AIDS). HIV is viral infection that slowly weakens your immune system, the body’s natural defense system again disease and infection, over time. HIV is contracted through bodily fluids such as blood, semen, vaginal fluids, and saliva, which is why an HIV infected person should never share personal items such as toothbrushes and razors and should always wear protection (like a condom) during sexual intercourse. If HIV goes untreated for too long, the HIV infected person risks developing AIDS. A person has AIDS when HIV has weakened the immune system so much to the point where it can no longer defend against disease and infection, which can become fatal. There is no cure for HIV at this time, but using medication, HIV can be kept under control and AIDS can be prevented.

Norvir (ritonavir) is effective in treating HIV because it is able to decrease the amount of HIV in your body to allow the immune system can work more easily. Ritonavir also has the ability to “boost” the levels of other protease inhibitors, which helps these medications work better.

Only take this medication the way that your doctor has directed you too. Taking the incorrect dose can lead to unwanted side effects, ineffectiveness, or adverse interactions.

You must take Norvir tablets with food and swallowed whole. Ensure you are taking any other medications you may have been prescribed for your condition as well.

Store this medication at room temperature in a low risk area of heat and moisture.
