Omeprazole 101
What is Omeprazole
Omeprazole is a Proton Pump Inhibitor (PPI), which is a class of drugs used to treat frequent heartburn symptoms by reducing the acid in the stomach that can cause heartburn.
How Does Omeprazole Work
Omeprazole works by binding to the acid-producing pumps in the stomach and turning them off, blocking the acid at the source. It starts working as early as an hour but may take 1-4 days for full effect.

Omeprazole Benefits
One of the benefits of omeprazole is blocking heartburn relief all day and all night after taking one pill in the morning.*
The active ingredient omeprazole works to fight heartburn differently from treatments like acid controllers/H2s or antacids. Omeprazole is a proton pump inhibitor (PPI) and PPIs are the strongest class of frequent heartburn medicines. They work to prevent excess acid production…something that antacids just can’t do.
| Antacids | Acid Controllers/H2 Blockers | Prilosec OTC’s Omeprazole |
|---|---|---|
| • Provide immediate relief by neutralizing acid in the esophagus • Do not reduce acid production at its source, and can actually turn on acid production, which may lead • Heartburn relief lasts 1-3 hours and you may need to take several times throughout the day | • Partially reduce acid production by blocking only one of the signals that tell your body to produce acid • Heartburn relief lasts 12 hours, so by the time you sit down for dinner, you might need to take a second dose | • Blocks many of the stomach pumps that produce acid • Prevents excess acid production that can cause heartburn** • Heartburn relief lasts for 24 hours with 1 pill in the morning*** • Has a unique delayed release formula |
PPIs work by reducing the production of stomach acid, providing relief from symptoms like frequent heartburn that are caused by excess acid production
