When did Prilosec (omeprazole) switch from prescription to OTC?

Prilosec became available over the counter (OTC) in the United States in 2003.

What product wording should you look for on the OTC version?

The OTC option is omeprazole (the active ingredient in Prilosec). OTC labeling in the U.S. generally centers on treatment of frequent heartburn (an acid-related symptom) rather than the full range of prescription indications.
