Truvada is not approved for the treatment of chronic hepatitis B virus (HBV) infection. If you have both HIV and HBV infection and take Truvada, your HBV infection may get worse (flare up) if you stop taking Truvada. But do not stop taking Truvada without first talking to your health care provider. If your health care provider tells you to stop Truvada, you will be monitored closely for several months to check your HBV infection, or you may receive a medicine to treat your HBV infection.

Do not take Truvada to reduce the risk of getting HIV -- also called pre-exposure prophylaxis or PrEP -- unless you are confirmed to be HIV negative.

While taking Truvada, it is important to keep all of your appointments with your health care provider.


What Is Truvada?

Truvada is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the following uses:

Truvada is a single pill that contains the following two different HIV medicines:

Both HIV medicines belong to a class (group) of HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs). NRTIs block an HIV enzyme called reverse transcriptase. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking reverse transcriptase, the two drugs in combination prevent HIV from multiplying and can reduce the amount of HIV in the body.

HIV medicines can't cure HIV/AIDS, but taking a combination of HIV medicines (called an HIV regimen) every day helps people with HIV live longer, healthier lives. Whether you are taking Truvada for HIV prevention or in combination with other HIV medicines for HIV treatment, don't cut down on, skip, or stop taking your HIV medicine(s) unless your health care provider tells you to.


What Should I Tell My Health Care Provider Before Taking Truvada?

Before taking Truvada, tell your health care provider:

Take Truvada according to your health care provider's instructions.

If you take Truvada to reduce your risk of getting HIV, you will get tested for HIV at least every 3 months. Truvada used for PrEP must be taken every day to give the best protection against HIV infection. Always combine use of Truvada with other prevention methods, such as condoms.

If you take too much Truvada, contact your health care provider or local poison control center (1-800-222-1222) right away, or go to the nearest hospital emergency room.

What Should I Do if I Forget a Dose?

Take the missed dose as soon as you remember it. But if it is almost time for your next dose, skip the missed dose and just take your next dose at the regular time. Do not take more than one dose of Truvada in a day. Do not take two doses at the same time to make up for a missed dose.
