Efavirenz/Emtricitabine/Tenofovir Tablet

HIV

What is efavirenz, emtricitabine, and tenofovir (Atripla)? Atripla is a combination antiviral medication that prevents human immunodeficiency virus (HIV) from reproducing in your body. Atripla is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). Atripla is not a cure for HIV or AIDS. Atripla is for use in adults and children who are at least 12 years old and weigh at least 88 pounds (40 kilograms). Atripla may also be used for purposes not listed in this medication guide. Warnings Do not take Atripla together with adefovir, atazanavir, voriconazole, or medications that contain emtricitabine, lamivudine, or tenofovir. Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together. Atripla can cause severe or fatal liver problems. Call your doctor at once if you have symptoms such as stomach pain or swelling, loss of appetite, dark urine, or yellowing of your skin or eyes. You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Call your doctor or get emergency medical help if you have unusual muscle pain, trouble breathing, stomach pain, dizziness, feeling cold, or feeling very weak or tired. If you've ever had hepatitis B, it may become active or get worse after you stop using Atripla. You may need frequent liver function tests for several months. Before taking this medicine You should not take efavirenz, emtricitabine, and tenofovir if you are allergic to efavirenz (Sustiva), emtricitabine (Emtriva), or tenofovir (Viread). Do not take Atripla together with adefovir, atazanavir, voriconazole, or any medications that contain emtricitabine, lamivudine, or tenofovir (such as Combivir, Complera, Descovy, Epivir, Epzicom, Genvoya, Odefsey, Stribild, Trizivir, Truvada, Vemlidy). Tell your doctor if you have ever had: liver or kidney disease; long QT syndrome; mental illness, use of antipsychotic medication, or injection drug use; epilepsy or other seizure disorder; low bone mineral density; or hepatitis B or C infection. You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, if you've taken HIV medication for a long time, or if you are a woman. Ask your doctor about your risk. Atripla can cause birth defects. Do not use if you are pregnant, and do not get pregnant for at least 12 weeks after you stop taking Atripla. Atripla can make hormonal birth control less effective, including birth control pills, injections, implants, skin patches, and vaginal rings. To prevent pregnancy while using Atripla, use a barrier form of birth control: condom, diaphragm, cervical cap, or contraceptive sponge. Women with HIV or AIDS should not breast-feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk. How should I take Atripla? Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed. Take this medicine on an empty stomach with a full glass of water. You will need frequent medical tests. This medicine may affect a drug-screening urine test and you may have false results. Tell the laboratory staff that you use Atripla. Store Atripla in the original container at room temperature, away from moisture, heat, and light. Keep the bottle tightly closed when not in use. If you've ever had hepatitis B, this virus may become active or get worse in the months after you stop using Atripla. You may need frequent liver function tests while using this medicine and for several months after your last dose. What happens if I miss a dose? Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time. What happens if I overdose? Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include uncontrolled muscle movements. What should I avoid while taking Atripla? Avoid driving or hazardous activity until you know how efavirenz, emtricitabine, and tenofovir will affect you. Your reactions could be impaired. Using this medicine will not prevent your disease from spreading. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person. Atripla side effects Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling). Mild symptoms of lactic acidosis may worsen over time, and this condition can be fatal. Get emergency medical help if you have: unusual muscle pain, trouble breathing, stomach pain, vomiting, irregular heart rate, dizziness, feeling cold, or feeling very weak or tired. Call your doctor at once if you have: unusual thoughts or behavior, anger, severe depression, thoughts of hurting yourself or others, hallucinations; a seizure (convulsions); kidney problems--increased thirst and urination, muscle pain or weakness; or liver problems--swelling around your midsection, right-sided upper stomach pain, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
