Retrovir Drug Interactions

When medications such as fluconazole, methadone, or rifampin are taken with Retrovir, drug interactions may occur. While some medicines may increase the level of Retrovir in your blood and cause potentially serious side effects, others may decrease Retrovir levels and possibly reduce the effectiveness of the drug. Other medications that can cause Retrovir drug interactions include ritonavir, nelfinavir, probenecid, and ganciclovir.
