We're sorry that you didn't experience the expected relief, R Bright. Prilosec OTC is different from antacids and other acid reducers. It may take up to 4 days for Prilosec OTC to take full effect, although some people get complete relief of symptoms within 24 hours. You should use Prilosec OTC once a day for 14 days. If heartburn symptoms continue or worsen while using this product, this may be a sign of a more serious condition, and you should stop taking the product and consult your doctor. We're sorry this has been your experience, and our Prilosec OTC Team would like to gather details to see how we can further help. Please give us a call at 1-800-289-9181 from 9AM — 6PM EST Monday – Friday.
