I guess it works. I don't get as much pain when I eat, but if I do forget it the pain that I have when I do eat comes back terribly. I still have some pain when I eat, but it's not nearly as rough when I take the Omeprazole.

What is omeprazole?

Omeprazole decreases the amount of acid produced in the stomach.

Omeprazole is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions caused by excess stomach acid. Omeprazole is also used to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).

Omeprazole may also be given together with antibiotics to treat gastric ulcer caused by infection with helicobacter pylori (H. pylori).

Omeprazole may also be used for other purposes not listed in this medication guide.


Precautions

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.

Do not use this medication if you are allergic to omeprazole.

Ask a doctor or pharmacist about using this medicine if you have heart disease or liver disease. You may need a dose adjustment or special tests to safely take this medication.

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.

  • trouble or pain with swallowing;
  • bloody or black stools;
  • vomit that looks like blood or coffee grounds;
  • heartburn that has lasted for over 3 months;
  • frequent chest pain;
  • heartburn with wheezing;
  • unexplained weight loss;
  • nausea or vomiting; or
  • stomach pain.
