Emtricitabine, Rilpivirine, and Tenofovirpronounced as (em tri sit' uh bean) (ril'' pi vir' een) (te noe' fo veer)
Emtricitabine, rilpivirine, and tenofovir 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 emtricitabine, rilpivirine, and tenofovir. If you have HBV and you take emtricitabine, rilpivirine, and tenofovir, your condition may suddenly worsen when you stop taking emtricitabine, rilpivirine, and tenofovir. Your doctor will examine you and order lab tests regularly for several months after you stop taking emtricitabine, rilpivirine, and tenofovir to see if your HBV has worsened.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests before and during your treatment to check your body's response to emtricitabine, rilpivirine, and tenofovir.
Talk to your doctor about the risks of taking emtricitabine, rilpivirine, and tenofovir.
Why is this medication prescribed?
The combination of emtricitabine, rilpivirine, and tenofovir is used to treat HIV in adults and children who weigh at least 77 pounds (35 kilograms). Emtricitabine, rilpivirine, and tenofovir are in a class of medications called nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs). They work by slowing the spread of HIV in the body. Although emtricitabine, rilpivirine, and tenofovir 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 emtricitabine, rilpivirine, and tenofovir comes as a tablet to take by mouth. It is usually taken with a meal (not just a protein drink) once a day. Take emtricitabine, rilpivirine, and tenofovir 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 emtricitabine, rilpivirine, and tenofovir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may prescribe or recommend a calcium and vitamin D supplement to take during your treatment. You should take these supplements every day as directed by your doctor.
Continue to take emtricitabine, rilpivirine, and tenofovir even if you feel well. Do not stop taking emtricitabine, rilpivirine, and tenofovir without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

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).
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.
In case of emergency/overdose
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
What other information should I know?
