Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
If you have hepatitis B infection, your hepatitis symptoms may get worse or become very serious if you stop taking this medication. Talk with your doctor before stopping this medication. Your doctor will monitor liver tests for several months after you stop emtricitabine/rilpivirine/tenofovir alafenamide. Tell your doctor right away if you have symptoms of worsening liver problems.
This product contains 3 different medications: emtricitabine, rilpivirine, and tenofovir alafenamide. It is used to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Emtricitabine and tenofovir alafenamide belong to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs). Rilpivirine belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Emtricitabine/rilpivirine/tenofovir alafenamide is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This product may also be used to reduce the risk of getting HIV infection after contact with the virus. Consult your doctor for more details.
How To Use
Read the Patient Information Leaflet if available from your pharmacist before you start taking this medication and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with a meal as directed by your doctor, usually once daily.
Medications which reduce or block stomach acid (such as proton pump inhibitors/PPIs, H2 blockers, antacids) may reduce the absorption of rilpivirine, making it work less well. Do not take PPIs (such as omeprazole, lansoprazole) while using this medication. If you take antacids, take the antacids at least 2 hours before or at least 4 hours after this medication. If you take H2 blockers (such as famotidine, ranitidine), take them at least 12 hours before or at least 4 hours after this medication.
It is very important to continue taking this medication exactly as prescribed by your doctor. Do not take less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase and/or make the infection more difficult to treat (resistant).
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of side effects may increase.
For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time every day.
Headache or trouble sleeping may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including:
- unexplained weight loss
- severe tiredness
- muscle aches/weakness that doesn't go away
- headaches that are severe or don't go away
- joint pain
- numbness/tingling of the hands/feet/arms/legs
- vision changes
- signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores)
- signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter)
- signs of a certain nerve problem known as Guillain-Barre syndrome (such as trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking)
- signs of liver disease (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine)
Tell your doctor right away if you have any serious side effects, including:
- signs of kidney problems (such as change in the amount of urine, pink/bloody urine)
- mental/mood changes (such as depression, thoughts of suicide)
Rarely, this medication can cause a severe (sometimes fatal) blood problem (lactic acidosis). Tell your doctor right away if you develop symptoms of lactic acidosis (such as deep/rapid breathing, drowsiness, nausea/vomiting, unusual weakness).
Get medical help right away if you have any very serious side effects, including:
- fast/irregular heartbeat
- severe dizziness
Changes in body fat may occur while you are taking this medication (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs). The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of exercise to reduce this side effect.
This medication can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Get medical help right away if you develop any rash.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
- itching/swelling (especially of the face/tongue/throat)
- severe dizziness
- trouble breathing
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Rilpivirine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using this medication, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:
- certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
- family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using this medication safely.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
During pregnancy, this medication should be used only when clearly needed. Treatment can lower the risk of passing HIV infection to your baby, and this medication may be part of that treatment. Discuss the risks and benefits with your doctor.
Emtricitabine passes into breast milk. It is unknown if rilpivirine or tenofovir alafenamide passes into breast milk. Because breast milk can transmit HIV, do not breast-feed.
