How Prilosec OTC Works To Block Frequent Heartburn?

Frequent heartburn sufferers know the burning sensation in the chest all too well, especially after a particularly spicy meal or a second cup of coffee as a mid-afternoon pick-me up. Heartburn is uncomfortable, and once it starts, you want relief. The good news: You can tackle the discomfort from frequent heartburn with Prilosec OTC. Prilosec OTC can block heartburn, providing relief all day and all night, with one pill in the morning.*

How Prilosec OTC Works

When you eat, millions of tiny pumps in your stomach lining create acid to break down food. Normally, your lower esophageal sphincter (LES) opens and closes to let food pass from your esophagus into your stomach. When your LES relaxes, excess acids can flow up, or reflux, into your esophagus. This can create the painful, burning sensation of heartburn.

Prilosec OTC works by preventing the excess acid production that can cause heartburn.* Its unique delayed-release formula helps it pass through tough stomach acids. With Prilosec OTC, you can block the acid that causes frequent heartburn for 24 hours with one pill in the morning.*

How to Take Prilosec OTC

Prilosec OTC should be taken once in the morning for up to 14 days, up to three times per year (or every four months). When starting a course, know that it can take 1-4 days for full effect. Some users feel relief as soon as 24 hours after the first pill—but if that’s not the case for you, stay the course and take the entire 14 days of dosing. Prilosec OTC isn’t meant for immediate relief, but one pill in the morning can block heartburn all day and all night.*

If you feel you need Prilosec OTC for any time beyond that, consult with your doctor. You want to make sure you’re not missing a bigger health problem.
