With one Prilosec OTC pill a day, you can block frequent heartburn symptoms before they strike for a full 24 hours of heartburn relief. That way you can power on with your day—and rest at night—without concern that your frequent heartburn will flare up. That’s because Prilosec OTC fights heartburn day and night by shutting down many of the acid pumps in your stomach. It’s the all-day, all-night heartburn protection you need.
When you eat, millions of tiny pumps in your stomach lining create acid to break down food. Normally your lower esophageal sphincter (LES) works as a door, opening and closing to let food pass from your esophagus into your stomach.
When your LES relaxes, excess acids flow up, or reflux, into your esophagus. This creates the painful sensation of heartburn.
Prilosec OTC works by directly blocking many of the active stomach pumps that produce acid before they start. Prilosec OTC is a proton pump inhibitor (PPI). The way Prilosec OTC works to fight heartburn sets it in a whole separate class from other treatments such as histamine blockers or antacids.
