What is Biktarvy?
Biktarvy is a complete HIV-1 treatment in a once-a-day single tablet containing three antiviral medicines bictegravir, emtricitabine, and tenofovir. Biktarvy works by preventing HIV from multiplying in your body and lowers HIV blood levels, which decreases your chance of developing AIDS and HIV-related illnesses such as cancer or serious infections. Biktarvy is not a cure for HIV.
Human immunodeficiency virus type 1 (HIV-1) is the virus that causes acquired immune deficiency syndrome (AIDS).
Who can take Biktarvy?
Biktarvy is an FDA-approved medicine used as a complete regimen for treatment of HIV-1 infection in adults and pediatric patients who weigh at least 14 kg. Bikarvy can be used by patients who have not taken HIV-1 medicine in the past or to replace their current HIV-1 medicine if they are:
- virologically-suppressed (HIV-1 RNA less than 50 copies per mL)
- on a stable antiretroviral regimen with no history of treatment failure and
- no known substitutions associated with resistance to the individual components of BIiktarvy (bictegravir, emtricitabine, and tenofovir)
How does Biktarvy work?
Biktarvy contains three antiviral medicines that stop viruses from replicating and therefore reduces the number of viruses in your body.
Bictegravir is from a class of medications called integrase strand transfer inhibitors (INSTIs). Emtricitabine and tenofovir alafenamide are from the class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). Bictegravir, emtricitabine, and tenofovir are antiviral medicines that stop the HIV virus from multiplying.
Worsening of hepatitis B virus (HBV) infection.
Your healthcare provider will test you for HBV infection before or when you start treatment with this medicine. If you have HBV infection and take Biktarvy, your HBV may get worse (called a flare-up) if you stop taking Biktarvy. A "flare-up" is when your HBV infection suddenly returns worse than before.
Do not run out of Biktarvy. You should refill your prescription or talk to your healthcare provider before your Biktarvy is all gone.
Do not stop taking this medicine without first talking to your healthcare provider.
If you stop taking this medicine, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your liver and may need to give you a medicine to treat hepatitis B. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking this medicine.
Before taking this medicine
You should not use Biktarvy if you are allergic to antiviral medicines bictegravir, emtricitabine, or tenofovir contained in medicines such as Atripla, Complera, Emtriva, Descovy, Genvoya, Odefsey, Stribild, or Truvada.
Some medicines can cause unwanted or dangerous effects when used with Biktarvy, and your doctor may need to change your treatment plan. Do not take Biktarvy if you also take a medicine that contains:
Tell your doctor if you have or ever had:
Tell your healthcare provider if you are pregnant or plan to become pregnant during treatment with Biktarvy. It is not known if Biktarvy can harm your unborn baby. There is a pregnancy registry for women who take this medicine during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. Talk with your healthcare provider about how you can take part in this registry.
You should NOT breastfeed if you take Biktarvy.
- You should not breastfeed if you have HIV-1 because of the risk of passing HIV-1 to your baby.
- At least one of the medicines in Bikatrvy can pass to your baby in your breast milk. It is not known if the other medicines in Biktarvy can pass into your breast milk.
Talk with your healthcare provider about the best way to feed your baby.
How should I take Biktarvy?
Take Biktarvy exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Biktarvy is a complete HIV-1 treatment regimen. You should not take it with other HIV-1 medicines.
- Take one Biktarvy tablet once a day, with or without food.
- If you are unable to swallow a whole tablet, you can split the tablet in half and swallow each part separately, as long as all parts are swallowed within about 10 minutes.
- You should not change your dose, or stop taking this medicine without first talking with your healthcare provider. Stay under a healthcare provider's care during treatment with this medicine.
- If you take antacids or supplements that contain iron or calcium, take Biktarvy with food at the same time that you take these antacids or supplements.
- If you take antacids that contain aluminum or magnesium, take Biktarvy at least 2 hours before or 6 hours after you take these antacids.
- If you are on dialysis, take your daily dose of Biktarvy following dialysis.
- When your medicine supply starts to run low, get more from your healthcare provider or pharmacy, so you do NOT run out. This is very important because if the medicine is stopped for even a short time, the amount of virus in your blood may increase and the virus may develop resistance to Biktarvy and become harder to treat.
- You will need frequent medical tests.
- Do not miss a dose of Biktarvy.

Yes, Dovato (dolutegravir and lamivudine) has been associated with significant weight gain in people living with HIV, although the exact mechanism is not fully understood. Studies have shown that weight gain with dolutegravir can range from 2.4 to 6 kg (5.3 to 13.2 lb) after one year of treatment. Continue reading
Biktary is not listed as being associated with weight gain in the package insert. However, recent research suggests all integrase strand inhibitors such as bictegravir found in Biktary may be linked with some weight gain. Studies have demonstrated a median weight gain of between 1 kg (2.2 lbs) and 4 (8.8 lbs) kg over one to two years of follow-up. However, some patients have seen a greater than 10% weight gain.

Biktarvy is not an immunosuppressant, it can actually help your immune system because it increases the number of CD4 T-cells in your blood. T-cells are an important part of your immune system because they help your body fight off infections. Biktarvy reduces the amount of HIV in your body which improves your immune system and reduces your risk of developing illnesses linked to HIV infection. Continue reading
