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.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

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
