Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, dizziness, pain spreading to the arm or shoulder, sweating, nausea or vomiting, and a general ill feeling.

Before using this medication, tell your doctor if you are allergic to any drugs, or if you have heart disease or liver disease. You may need a dose adjustment or special tests to safely take this medication.

Omeprazole is not for immediate relief of heartburn symptoms.

Some conditions are treated with a combination of omeprazole and antibiotics. To best treat your condition, use all of your medications as directed by your doctor. Be sure to read the medication guide or patient instructions provided with each of your medications. Do not change your doses or medication schedule without advice from your doctor.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the condition is completely treated.

Prilosec OTC (over-the-counter) should be taken only once every 24 hours for 14 days. It may take up to 4 days for full effect. Do not take more than one tablet every 24 hours.

Allow at least 4 months to pass before you start another 14-day treatment with Prilosec OTC. Call your doctor if you have additional symptoms and need treatment before the 4 months has passed.
