How long does Omeprazole Magnesium stay in your body?

The elimination half-life of omeprazole magnesium is about 0.5 to 1 hour (roughly half an hour to an hour) in healthy adults — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. The half-life is longer in older adults (about 1 hour) and in people with chronic liver disease (nearly 3 hours); its metabolites have little or no activity, but because omeprazole irreversibly binds the stomach's acid pump, its acid-blocking effect lasts far longer than this short half-life would suggest.

It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.
