Omeprazole (Prilosec) is an inexpensive drug used to treat certain conditions where there is too much acid in the stomach, like ulcers and gastroesophageal reflux disease (GERD). It is more popular than comparable drugs. It is available in both generic and brand versions, and without a prescription. Generic omeprazole is covered by most Medicare and insurance plans, but some pharmacy coupons or cash prices may be lower.

Get Prilosec for as low as $452.71, which is 18% off the average retail price of $552.35 for the most common version, by using a GoodRx coupon.
