Atripla is not approved for the treatment of chronic HBV infection. If you have both HIV and HBV infection and take Atripla, your HBV infection may get much worse (flare up) if you stop taking Atripla. The HBV drug adefovir dipivoxil (brand name: Hepsera) should not be taken with Atripla.
If you take Atripla, you should not take certain other HIV medicines. Atripla may interact with some drugs, which can cause serious or life-threatening side effects.
While taking Atripla, it is important to keep all of your appointments with your health care provider.
What Is Atripla?
Atripla is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children 12 years of age and older who weigh at least 88 pounds (40 kg). Atripla can be used alone as a complete treatment regimen or with other HIV medicines.
Atripla contains the following three different HIV medicines combined in one pill:
Both NNRTIs and 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 three 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. HIV medicines also reduce the risk of HIV transmission.
