i would like to know why you want to take otc zantac. both of these medications are used to treat heartburn but they are usually not taken together. it should be one or the other. zantac works by trying to decrease the amount of acid in the stomach where prilosec turns off the pump that makes stomach acid. typically you should take prilosec for 14 days in the treatment of heartburn. i would also like to ask if you are taking any other medications since zantac can interact with many of them.
can i take otc zantac after taking otc prilosec?
