How does this medication work? What will it do for me?

Omeprazole belongs to the family of medications called proton pump inhibitors (PPIs). It slows or prevents the production of acid within the stomach.

It is used to treat conditions where reduction in acid secretion is required for proper healing, including stomach and intestinal ulcers (gastric and duodenal ulcers), the prevention and treatment of ulcers associated with medications known as NSAIDs, reflux esophagitis, Zollinger-Ellison syndrome, heartburn, and gastroesophageal reflux disease (GERD).

It is also used in combination with antibiotics to treat stomach ulcers caused by H. pylori bacteria.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.



How should I use this medication?

The usual recommended dose of omeprazole is 10 mg to 40 mg once daily. The dose and length of treatment depends on the condition being treated. This medication can be taken with or without food.

When used to treat stomach ulcers caused by H. pylori in adults, the dose of omeprazole is 20 mg twice daily taken with amoxicillin 1,000 mg twice daily and clarithromycin 500 mg twice daily, all for 7 days. Another dosing regimen for H. pylori infections is omeprazole 20 mg, metronidazole 500 mg, and clarithromycin 250 mg, all twice daily for 7 days.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
