Important Safety Information

What is the most important information I should know about TRUVADA for PrEP?

Before taking TRUVADA for PrEP:
  • You must be HIV-negative before you start taking TRUVADA for PrEP. You must get tested to make sure that you do not already have HIV-1. Do not take TRUVADA to reduce the risk of getting HIV-1 unless you are confirmed to be HIV-negative.
  • Many HIV-1 tests can miss HIV-1 infection in a person who has recently become infected. If you have flu-like symptoms, you could have recently become infected with HIV-1. Tell your healthcare provider if you had a flu-like illness within the last month before starting or at any time while taking TRUVADA for PrEP. Symptoms of new HIV-1infection include tiredness, fever, joint or muscle aches, headache, sore throat, vomiting, diarrhea, rash, night sweats, and/or enlarged lymph nodes in the neck or groin.
While taking TRUVADA for PrEP:
  • You must continue to use safer sex practices. Just taking TRUVADA for PrEP may not keep you from getting HIV-1.
  • You must stay HIV-negative to keep taking TRUVADA for PrEP:
    • Get tested for HIV-1 at least every 3 months.
    • If you think you were exposed to HIV-1, tell your healthcare provider right away.
  • To further help reduce your risk of getting HIV-1:
    • Know your HIV status and the HIV status of your partners.
    • Get tested for other sexually transmitted infections. Other infections make it easier for HIV to infect you.
    • Get information and support to help reduce risky sexual behavior, such as having fewer sex partners.
    • Do not miss any doses of TRUVADA. Missing doses may increase your risk of getting HIV-1 infection.
  • If you do become HIV-1 positive, you need more medicine than TRUVADA alone to treat HIV-1. TRUVADA by itself is not a complete treatment for HIV-1. If you have HIV-1and take only TRUVADA, your HIV-1 may become harder to treat over time.
TRUVADA can cause serious side effects:
  • Worsening of hepatitis B (HBV) infection. TRUVADA is not approved to treat HBV. If you have HBV and stop taking TRUVADA, your HBV may suddenly get worse. Do not stop taking TRUVADA without first talking to your healthcare provider, as they will need to monitor your health.

Who should not take TRUVADA for PrEP?

Do not take TRUVADA for PrEP if you:
  • Already have HIV-1 infection or if you do not know your HIV-1 status. If you are HIV-1positive, you need to take other medicines with TRUVADA to treat HIV-1. TRUVADA by itself is not a complete treatment for HIV-1. If you have HIV-1 and take only TRUVADA, your HIV-1 may become harder to treat over time.
  • Also take certain medicines to treat hepatitis B infection.

What are the other possible side effects of TRUVADA for PrEP?

Serious side effects of TRUVADA may also include:
