Prilosec OTC was the first proton pump inhibitor (PPI) for the treatment of frequent heartburn available over the counter. Since becoming available without a prescription, Prilosec OTC has safely and effectively fought frequent heartburn for more than 11 million consumers.* And that number keeps growing.

The safety record of omeprazole magnesium—the active ingredient in Prilosec OTC—was demonstrated in 13 OTC clinical trials.¹

As with any drug, you’ll want to stop and ask a doctor if you experience any of the warnings as listed on the Prilosec OTC package label.

Stop use and ask a doctor if:

• Your heartburn continues or worsens
• You need to take this product for more than 14 days
• You need to take more than one course of treatment every four months
