How does Losec 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.

Omeprazole 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.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. 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 Losec?

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 ulcers in the duodenum, the recommended adult dose is 20 mg taken once daily for 2 to 4 weeks.

To treat ulcers in the stomach, reflux esophagitis, and ulcers associated with the use of NSAIDs, the recommended adult dose is 20 mg taken once daily for 4 to 8 weeks.

For treatment of heartburn, the recommended adult dose is 20 mg daily.

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.

When treating Zollinger-Ellison syndrome, the dose of omeprazole varies, but is often higher than the doses used to treat ulcers. Doses larger than 80 mg daily are often needed.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

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. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, protect it from moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
