Since the beginning, we’ve led the way in OTC frequent heartburn treatments. We were first on the market and have continued to provide relief to heartburn sufferers with our trusted formula. For nearly 5 years now, Prilosec OTC has been in the strongest class of one-pill-a-day heartburn medicine available over the counter.
Proven Strength for Heartburn Relief

Prilosec OTC is strong enough to fight heartburn before it begins. It’s the only over-the-counter PPI (proton pump inhibitor) clinically proven to block heartburn for 24 hours.
And that means with 1 pill a day for 14 days, you get the relief you need from the pain of frequent heartburn.*
And, while taking Prilosec OTC, heartburn won’t keep coming back.
In a recent study, we tested the strength of Prilosec OTC against frequent heartburn. Take a look at the results:
|78% ||of consumers were heartburn free on the first night |
|81% ||of consumers had complete relief*/only mild symptoms on day one |
|94% ||of consumers were satisfied with how well Prilosec OTC worked |
See for yourself if Prilosec OTC is right for you.

Why Prilosec OTC Is Different
As the first over-the-counter proton pump inhibitor (PPI), Prilosec OTC is different from many other heartburn treatments and medications. Here’s a quick breakdown:
PPI (Proton Pump Inhibitor)
When you eat, millions of tiny pumps in your stomach produce acid to break down food — heartburn occurs when these excess acids reflux into your esophagus. Prilosec OTC works by directly blocking many of these pumps. Your stomach produces enough acid to digest food, but reduces excess acid — making it the most effective heartburn treatment choice and the #1 doctor recommended OTC acid reducer.† Prilosec OTC blocks heartburn for 24 hours with one pill a day.*
Antacids neutralize the acid in your stomach. Unlike the proactive PPI, antacids are commonly taken after you eat or when pain begins. While no heartburn treatments cure the condition, antacids provide only temporary relief.
H2 Blockers relieve heartburn symptoms by reducing the acid production. They begin working within an hour and last for 12 hours. H2 Blockers are not as effective in treating severe heartburn as PPIs.
*It’s possible with Prilosec OTC. Use as directed for 14 days for treating frequent heartburn.
