Emtricitabine, Rilpivirine, and Tenofovirpronounced as (em tri sit' uh bean) (ril'' pi vir' een) (te noe' fo veer)
The combination of emtricitabine, rilpivirine, and tenofovir may cause life-threatening damage to the liver and a potentially life-threatening condition called lactic acidosis (buildup of lactic acid in the blood) when used alone or in combination with other medications that treat human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS). Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: nausea, vomiting, pain in the upper right part of your stomach, loss of appetite, flu-like symptoms, extreme tiredness, unusual bleeding or bruising, weakness, dizziness, lightheadedness, fast or irregular heartbeat, trouble breathing, dark yellow or brown urine, light-colored bowel movements, yellowing of the skin or eyes, feeling cold, especially in the arms or legs, or muscle pain that is different than any muscle pain you usually experience.
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 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 12 years of age and older. 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.

If you have new or worsening symptoms at any time during your treatment with emtricitabine, rilpivirine, and tenofovir, be sure to tell your doctor.
