Epivir Drug Interactions
When zalcitabine, ribavirin, or interferon medications are taken together with Epivir, drug interactions may potentially occur. These interactions could increase the level of Epivir in your blood, decrease the effectiveness of the medicines, or increase your risk for dangerous side effects. Telling your healthcare provider about other drugs you are taking can help prevent these negative Epivir interactions.
Epivir® (lamivudine) can potentially interact with a few other medicines. Some of these medicines that may lead to Epivir interactions include:
- Interferon medications, such as:
- Interferon alfa-2a (Roferon®-A)
- Interferon alfa-2b (Intron® A)
- Interferon alfa-2b and ribavirin (Rebetron®)
