Generic Prilosec
A generic version of prescription Prilosec (omeprazole) is currently available. Generic over-the-counter (OTC) versions of omeprazole are also available, although these products are not identical to prescription Prilosec.
Prilosec® (omeprazole) is a prescription medication used to treat several conditions related to the esophagus, stomach, and intestines. Prilosec is part of a class of drugs known as proton pump inhibitors (PPIs). Over-the-counter Prilosec OTC® (omeprazole magnesium) is also available for treating heartburn.
Prilosec is manufactured by AstraZeneca, while Prilosec OTC is made by Procter and Gamble. The patents for prescription Prilosec have expired and there are generic versions of prescription Prilosec available. "Generic" OTC omeprazole versions are also available.
Generic Prescription Prilosec
Generic prescription Prilosec capsules are available in the following strengths:
- Omeprazole 10 mg
- Omeprazole 20 mg
- Omeprazole 40 mg.
A generic version of prescription Prilosec packets for oral suspension is not yet available.
Generic omeprazole 20 mg OTC (over-the-counter) tablets and capsules are available, but they cannot be considered strictly equivalent to Prilosec. Most healthcare providers (and consumers) would agree that this difference is not important for most people. For practical purposes, the generic nonprescription versions should be considered equivalent to prescription Prilosec.
