Can I take Tagamet HB 200® if I am on other medication?
Consult your doctor before taking Tagamet HB 200® if you are taking a medication that contains theophylline (oral asthma medication), warfarin (blood thinning medication) or phenytoin (seizure medication). If you are concerned specifically about other prescription medications that you are taking, you may want to discuss this with your doctor. If you are taking other non-prescription heartburn medications, check with your doctor or pharmacist before using Tagamet HB 200® in conjunction with other heartburn medications.
