What is Biktarvy?

Biktarvy is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children weighing at least 55 lb (25 kg) and who meet certain requirements, as determined by a health care provider.

Biktarvy is a complete HIV treatment regimen and should not be used with other HIV medicines.

Biktarvy contains three different medicines: bictegravir, emtricitabine, and tenofovir alafenamide.

HIV medicines can’t cure HIV/AIDS, but taking HIV medicines every day helps people with HIV live longer, healthier lives. HIV medicines also reduce the risk of HIV transmission. If you are taking HIV medicines, don’t cut down on, skip, or stop taking them unless your health care provider tells you to.

What should I tell my health care provider before taking Biktarvy?

Before taking Biktarvy, tell your health care provider:

  • If you are allergic to any of the HIV medicines in Biktarvy (bictegravir, emtricitabine, or tenofovir alafenamide) or any other medicines.
  • If you have liver problems, including hepatitis B virus infection (HBV).
  • If you have kidney problems.
  • If you have any other medical conditions.
  • If you are pregnant or plan to become pregnant. Talk to your health care provider about the risks and benefits of using Biktarvy during pregnancy.
  • If you are breastfeeding or plan to breastfeed. Do not breastfeed if you have HIV or are taking Biktarvy.
  • If you are using hormone-based birth control (such as pills, implants, or vaginal rings). For more information about using birth control and HIV medicines at the same time, view the ClinicalInfo HIV and Birth Control infographic.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Biktarvy may affect the way other medicines or products work, and other medicines or products may affect how Biktarvy works. Taking Biktarvy together with certain medicines or products may cause serious side effects. Do not take Biktarvy if you take dofetilide or rifampin. Taking Biktarvy with dofetilide or rifampin can cause side effects that may be serious or life-threatening or could result in reduced effectiveness of Biktarvy.
