With just one Prilosec OTC® pill a day, you can block frequent heartburn symptoms before they begin for a full 24 hours with zero heartburn. So you can get through the day-and rest at night-without the worry of heartburn flare-ups on your mind. That's because Prilosec OTC fights heartburn by shutting down many of the acid pumps in your stomach, giving you zero heartburn for 24 hours-with one pill a day.*

* It's possible while taking Prilosec OTC. Use as directed for 14 days for treating frequent heartburn.
