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 31 lb (14 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.

For more information on the use of Biktarvy in people with HIV, please refer to the Guidelines for the Use of Antiretroviral Agents in Adults and Adolescents Living with HIV and the Guidelines for the Use of Antiretroviral Agents in Pediatric HIV Infection.

HIV medicines cannot 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, do not cut down on, skip, or stop taking them unless your health care provider tells you to.

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 taking Biktarvy during pregnancy. For more information on the use of Biktarvy during pregnancy, please refer to the Recommendations for the Use of Antiretroviral Drugs During Pregnancy and Interventions to Reduce Perinatal HIV Transmission in the United States.
  • If you are breastfeeding or plan to breastfeed. For women with HIV in the United States, the Guideline does not recommend breastfeeding. Before your baby is born, or if you are already breastfeeding, talk to your health care provider to discuss alternative options for feeding your baby.
  • 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 HIVinfo HIV and Birth Control infographic.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products (including St. John's wort) 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, life-threatening side effects.

Take Biktarvy according to your health care provider’s instructions. Do not miss a dose of Biktarvy, and do not change your dose or stop taking Biktarvy without first talking with your health care provider.

Take Biktarvy by mouth with or without food. If you are taking any other medicines or supplements, including antacids, carefully follow instructions on how to take them with Biktarvy.

What side effects can Biktarvy cause?

Biktarvy may cause side effects. Some side effects of Biktarvy can be serious, as noted above. Many side effects from HIV medicines, such as nausea or occasional dizziness, are manageable. See the HIVinfo fact sheet on HIV Medicines and Side Effects for more information.

Other possible side effects of Biktarvy include:

  • Changes in your immune system (called immune reconstitution inflammatory syndrome or IRIS). IRIS is a condition that sometimes occurs when the immune system begins to recover after treatment with an HIV medicine. As the immune system gets stronger, it may have an increased response to a previously hidden infection.
  • Diarrhea and headache.


Tell your health care provider if you have any side effect that bothers you or that does not go away.

These are not all the possible side effects of Biktarvy. To learn more about possible side effects of Biktarvy, read the drug label or package insert or talk to your health care provider or pharmacist.


You can report side effects to FDA at 1-800-FDA-1088 (1-800-332-1088) or online.
