Severe worsening of liver disease has occurred in some people co-infected with hepatitis B virus (HBV) and HIV when they stopped treatment with lamivudine, an anti-HIV medicine included in Combivir. Worsening of liver disease, sometimes causing death, has also occurred in people co-infected with hepatitis C virus (HCV) and HIV who were taking anti-HIV medicines and also being treated for HCV with interferon with or without ribavirin. Tell your health care provider about any side effects you have.
While taking Combivir, it is important to keep all of your appointments with your health care provider.
Combivir is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children. Combivir is always used in combination with other anti-HIV medicines.
Combivir contains the following two anti-HIV medicines combined in one pill: lamivudine and zidovudine. Lamivudine and zidovudine are types of anti-HIV medicines called nucleoside reverse transcriptase inhibitors (NRTIs). NRTIs block HIV reverse transcriptase, an HIV enzyme. This prevents HIV from replicating and lowers the amount of HIV in the blood.
Combivir does not cure HIV/AIDS. It is not known if Combivir reduces the risk of passing HIV to other people.
Before taking Combivir, tell your health care provider:
