What is bictegravir, emtricitabine, and tenofovir (Biktarvy)?
Biktarvy is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body.
Biktarvy is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). This medicine is not a cure for HIV or AIDS.
Biktarvy is for use in adults and children who weigh at least 31 pounds (14 kilograms) who have not received HIV-1 medicines, or to replace their current HIV-1 medicines for those who meet certain requirements.
Biktarvy may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking Biktarvy?
Some medicines can cause unwanted or dangerous effects when used with Biktarvy. Your doctor may need to change your treatment plan if you also use:
- dofetilide; or
- rifampin.
Tell your doctor if you have ever had:
- liver disease (especially cirrhosis or hepatitis B); or
- kidney disease.
Tell your doctor if you are pregnant. HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines to control your infection. Your name may be listed on a pregnancy registry to track the effects of Biktarvy on the baby.
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.
