Heartburn Treatments
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
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
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 to treat frequent heartburn. Visit PrilosecOTCGuarantee.com for Satisfaction Guarantee offer details.
