Overview of Evotaz - a Prescription Medication Used to Treat HIV Infection in Adults

Cobicistat reduces the action of enzymes in your liver that break down certain antiviral medicines. This allows the antiviral medicines to be used more safely and effectively at lower doses.
Atazanavir and cobicistat is a combination medicine given together with other antiviral medicines to treat human immunodeficiency virus (HIV) in adults. HIV is the virus that can cause acquired immunodeficiency syndrome (AIDS).This medicine is not a cure for HIV or AIDS.
