What is the most important information I should know about Atripla?

Atripla can cause serious side effects, including:

  • Worsening of hepatitis B virus (HBV) infection. Your healthcare provider will test you for HBV before starting treatment with Atripla. If you have HBV infection and take Atripla, your HBV may get worse (flare-up) if you stop taking Atripla. A "flare-up" is when your HBV infection suddenly returns in a worse way than before.
    • Do not stop taking Atripla without first talking with your healthcare provider.
    • Do not run out of Atripla. Refill your prescription or talk to your healthcare provider before your Atripla is all gone.
    • If you stop taking Atripla, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your HBV infection, or give you a medication to treat hepatitis B. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking Atripla.
