### Human:\nwhat is omeprazole used for?\n\n### Assistant: omeprazole is also known as prilosec otc. its actually a proton pump inhibitor and it is used to treat like heartburn; if you have it for more than two or three episodes a week. it can be used longer term in the treatment of gerd or a gastroesophageal reflux disease or then also possibly in the healing of ulcers. it's a very popular product. it's very well tolerated. but once again we want to make sure that patients know that pharmacists need to know if you are taking this medication over-the-counter. it could still interact with some other medications. so present your medication list to the pharmacist of everything that you are taking and we will make sure that everything looks okay.
