Evotaz

Generic name: Atazanavir And Cobicistat
Drug class: Antiviral combinations

Usage of Evotaz

Evotaz contains a combination of atazanavir and cobicistat. Aatazanavir is a protease inhibitor antiviral medication that prevents human immunodeficiency virus (HIV) from multiplying in your body. 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.

Evotaz is a prescription 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.

Evotaz is for use in adults and children who weigh at least 77 pounds (35 kilograms).

Do not use if you are pregnant. Evotaz may not work as well if you take it during pregnancy. You may also develop a serious condition called lactic acidosis if you take Evotaz with certain other HIV medicines during pregnancy. Tell your doctor right away if you become pregnant. You may need to use a different antiviral medicine.

Use your medications properly to control your infection. HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.

Atazanavir and cobicistat can make hormonal birth control less effective, including birth control pills, injections, implants, skin patches, and vaginal rings. To prevent pregnancy while using this medicine, use a barrier form of birth control: condom, diaphragm, cervical cap, or contraceptive sponge.

Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
