What is Truvada?Truvada is a combination medicine used to treat HIV (human immunodeficiency virus) infection (AIDS) with other anti-HIV medications. Truvada contains two medications, emtricitabine and tenofovir disoproxil fumarate. Both of these are types of HIV medications called nucleoside analogue reverse transcriptase inhibitors (NRTIs). Truvada works by lowering the amount of HIV in your blood.
What is the most important information I should know about Truvada?You must take Truvada with other HIV medications. Always stay on continuous HIV therapy to control your HIV infection and decrease HIV-related illnesses. Though Truvada can slow the progress of HIV, it is not a cure. Also, Truvada does not lower your chance of passing HIV/AIDS to others through sexual contact, sharing needles, or being exposed to your blood. You may continue to develop infections and other complications associated with HIV.
Truvada can cause a rare but serious condition called lactic acidosis (a build-up of an acid in the blood). Tell your doctor immediately if you feel very weak or tired; have unusual muscle pain; trouble breathing, or stomach pain with nausea and vomiting; feel cold, especially in your arms and legs; feel dizzy or lightheaded; or have a fast or irregular heartbeat.
Truvada can cause serious liver problems with liver enlargement and fat in the liver. Tell your doctor immediately if you experience yellowing of your skin or whites of your eyes, dark urine, light-colored stools, loss of appetite, nausea, or lower abdominal pain.
You have a higher chance of getting lactic acidosis or liver problems if you are a woman, are very overweight, or if you have been taking Truvada or similar products for a long time.
If you have hepatitis B virus (HBV) and stop taking Truvada, your HBV can worsen.
