Bictegravir, emtricitabine, and tenofovir alafenamide (AF) should not be used to treat hepatitis B virus infection (HBV; an ongoing liver infection). Tell your doctor if you have or think you may have HBV. Your doctor may test you to see if you have HBV before you begin your treatment with bictegravir, emtricitabine, and tenofovir. If you have HBV and you take bictegravir, emtricitabine, and tenofovir, your condition may suddenly worsen when you stop taking bictegravir, emtricitabine, and tenofovir.
Keep all appointments with your doctor and the laboratory. Your doctor will examine you and order lab tests before, during, and regularly for several months after you stop taking bictegravir, emtricitabine, and tenofovir to see if your HBV has worsened.
Talk to your doctor about the risk(s) of taking bictegravir, emtricitabine, and tenofovir.
Why is this medication prescribed?
The combination of bictegravir, emtricitabine, and tenofovir AF is used to treat human immunodeficiency virus (HIV) infection in certain adults and children weighing at least 55 pounds (25 kg) who have not received antiretroviral treatment in the past or who have been stable on other antiretroviral treatment(s). Bictegravir is in a class of medications called integrase strand transfer inhibitors (INSTIs). Emtricitabine and tenofovir AF are in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). The combination of bictegravir, emtricitabine, and tenofovir AF works by decreasing the amount of HIV in the body. Although bictegravir, emtricitabine, and tenofovir AF will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of getting or transmitting the HIV virus to other people.
How should this medicine be used?
The combination of bictegravir, emtricitabine, and tenofovir AF comes as a tablet to take by mouth. It is usually taken once daily with or without food. Take bictegravir, emtricitabine, and tenofovir AF at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bictegravir, emtricitabine, and tenofovir AF exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If unable to swallow the bictegravir, emtricitabine, and tenofovir AF tablet whole, you can cut the tablet in half and swallow each half separately as long as they are both swallowed within 10 minutes of each other.
Continue to take bictegravir, emtricitabine, and tenofovir AF even if you feel well. Do not stop taking bictegravir, emtricitabine, and tenofovir AF without talking to your doctor. If you stop taking bictegravir, emtricitabine, and tenofovir AF even for a short time, or skip doses, the virus may become resistant to medications and may be harder to treat.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not remove the desiccant pack that comes in the bottle.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
