Applies to:Zantac 25 mg EFFERdose (ranitidine) and Tarceva (erlotinib)
Talk to your doctor before using erlotinib together with ranitidine. Ranitidine can interfere with the absorption of erlotinib and reduce its effectiveness if they are taken too close together. In some cases, your doctor may want to prescribe alternatives that do not interact. Otherwise, you may be able to minimize the interaction by taking erlotinib at least 2 hours before or 10 hours after ranitidine. Contact your doctor if your condition worsens during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
