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 Omeprazole for as low as $5.17, which is 94% off the average retail price of $87.62 for the most common version, by using a GoodRx coupon.
