How is Prilosec OTC different from other many over-the-counter (OTC) heartburn products?
Prilosec OTC works differently from many other OTC heartburn products, such as antacids and other acid reducers. Prilosec OTC stops acid production at the source — the acid pumps that produces stomach acid. Prilosec OTC is to be used once a day (every 24 hours) every day for 14 days for treating frequent heartburn.
