What is Biktarvy?

Biktarvy contains a combination of bictegravir,  emtricitabine , and tenofovir. Bictegravir, emtricitabine, and tenofovir are antiviral medicines that prevent  human immunodeficiency virus (HIV ) from multiplying in your body.

Biktarvy is used to treat HIV, the virus that can cause  acquired immunodeficiency syndrome (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 is not a cure for HIV or AIDS.

Warnings

Biktarvy may cause a serious condition called  lactic acidosis . Too much lactic acid is a serious but rare medical emergency that can lead to death. Tell your healthcare provider right away if you get these symptoms: weakness or being more tired than usual, unusual muscle pain, being short of breath or fast breathing, stomach pain with nausea and vomiting, cold or blue hands and feet, feel dizzy or lightheaded, or a fast or abnormal heartbeat.

If you’ve ever had  hepatitis B , it may become active or get worse after you stop using Biktarvy. You may need frequent  liver function tests  for several months.

Before taking this medicine

You should not use Biktarvy if you are allergic to antiviral medicines that contain emtricitabine or tenofovir (such as  Atripla ,  Complera ,  Emtriva ,  Descovy ,  Genvoya ,  Odefsey ,  Stribild , or  Truvada ).

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

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.
