What is cobicistat, darunavir, emtricitabine, and tenofovir (Symtuza) (Symtuza)?
Cobicistat, darunavir, emtricitabine, and tenofovir (Symtuza) is a combination antiviral medicine used to treat human immunodeficiency virus (HIV), the virus that can cause the acquired immunodeficiency syndrome (AIDS). Symtuza is for use in adults and children weighing at least 88 pounds (40 kilograms). This medicine is not a cure for HIV or AIDS.
Symtuza is sometimes used in people who have never been treated with other HIV medications.
Symtuza is also used to replace other HIV medications in adults with suppressed viral loads. Your doctor will determine which medication is best for you.
Symtuza may also be used for purposes not listed in this medication guide.

If you plan to get pregnant, ask your doctor for another antiviral medicine to use during pregnancy. Use all medications properly to control your infection.

If you do not plan to get pregnant, ask your doctor about using a non-hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy. Symtuza can increase certain side effects when taken with hormonal birth control (pills, injections, implants, skin patches, vaginal rings).
