Generic Name: emtricitabine/tenofovir (EM-trye-SYE-ta-been/ten-OF-oh-vir)
Brand Name: Truvada
Severe and sometimes fatal lactic acidosis (a buildup of lactic acid in the blood) and liver problems have occurred with this type of medicine. The risk may be greater in women, patients who are very overweight, or patients who have been taking nucleoside medicines (eg, emtricitabine, tenofovir) for a long time.
Tell your doctor right away if you develop symptoms of lactic acidosis (eg, unusual weakness or tiredness; unusual muscle pain or cramps; fast or difficult breathing; stomach pain with nausea and vomiting; feeling cold, especially in the arms and legs; dizziness or light-headedness; fast or irregular heartbeat). Tell your doctor right away if you develop symptoms of liver problems (eg, yellowing of the skin or eyes, dark urine, pale stools, persistent loss of appetite, nausea, stomach pain).
Truvada has not been approved to treat hepatitis B virus (HBV) infection. The safety and effectiveness of Truvada in patients who have both HBV and HIV infection have not been confirmed. Some patients with both HBV and HIV infection who took Truvada experienced severe worsening of HBV infection after they stopped taking it. Patients who have HBV infection need close medical follow-up to check for worsening liver problems for at least several months after they stop Truvada. Keep all doctor and lab appointments. Do not stop taking Truvada without checking with your doctor.
If you are taking Truvada to reduce the risk of getting HIV, you must have a negative HIV test before you start Truvada and at least every 3 months during use. Tell your doctor if you think you have been exposed to HIV. Contact your doctor right away if you develop fever, headache, tiredness, joint or muscle aches, vomiting, diarrhea, sore throat, rash, night sweats, or swollen glands or lymph nodes, or if you have had any of these symptoms within 1 month before starting Truvada.
Truvada is used for:
Treating HIV infection in combination with other medicines. Truvada is also used in combination with safer sex practices to reduce the risk of getting HIV in patients who are at high risk of getting infected with HIV through sex. It may also be used for other conditions as determined by your doctor.
Truvada is an antiviral combination of 2 reverse transcriptase inhibitors. It works to treat HIV by reducing the amount of HIV in the body by blocking its ability to multiply. Exactly how it works to reduce the risk of getting HIV is not known.

- you are taking adefovir, medicines that contain lamivudine, or another medicine that contains emtricitabine or tenofovir
- you take a medicine that may harm your kidneys (eg, an aminoglycoside antibiotic [eg, gentamicin], amphotericin B, cyclosporine, a nonsteroidal anti-inflammatory drug [NSAID] [eg, ibuprofen], tacrolimus, vancomycin). Ask you doctor if you are not sure if any of your medicines might harm your kidneys
- you are taking Truvada to treat HIV and you also have severe kidney problems or you are on dialysis

- Do not stop taking Truvada without checking with your doctor. If you do, you may be at greater risk of getting HIV. Discuss any questions or concerns with your doctor.
