What is cobicistat, darunavir, emtricitabine, and tenofovir (Symtuza) (Symtuza)?
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.
Cobicistat, darunavir, emtricitabine, and tenofovir (Symtuza) is a combination medicine used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). Symtuza is not a cure for HIV or AIDS.
Cobicistat, darunavir, emtricitabine, and tenofovir may also be used for purposes not listed in this medication guide.
