Emtricitabine/ rilpivirine/ tenofovir
Generic Name: emtricitabine/rilpivirine/tenofovir (EM-trye-SYE-ta-been/RIL-pi-VIR-een/ten-OF-oh-vir)
Brand Name: Complera
Severe and sometimes fatal lactic acidosis (a buildup of lactic acid in the blood) and liver problems have occurred with tenofovir. The risk may be greater in women. It may also be greater in 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; 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).
Emtricitabine/rilpivirine/tenofovir has not been approved to treat hepatitis B virus (HBV) infection. The safety and effectiveness of emtricitabine/rilpivirine/tenofovir in patients who have both HBV and HIV infection have not been confirmed. Some patients with both HBV and HIV infection who took emtricitabine or tenofovir experienced severe worsening of HBV infection after they stopped taking them. Patients who have both HBV and HIV infection need close medical follow-up to check for worsening liver problems for at least several months after they stop emtricitabine/rilpivirine/tenofovir. Keep all doctor and lab appointments. Do not stop taking emtricitabine/rilpivirine/tenofovir without checking with your doctor.
Emtricitabine/ rilpivirine/ tenofovir is used for:
Treating HIV infection. Emtricitabine/rilpivirine/tenofovir is not a cure for HIV or AIDS. It may also be used for other conditions as determined by your doctor.
Emtricitabine/rilpivirine/tenofovir is an antiviral combination of a nonnucleoside reverse transcriptase inhibitor (NNRTI) and 2 nucleoside reverse transcriptase inhibitors (NRTIs). It works by reducing the amount of HIV in the body by blocking its ability to multiply.
