Compare Omeprazole vs. Carafate

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Omeprazole (Prilosec) and Sucralfate (Carafate) are both used to treat conditions related to stomach acid, but they work in different ways. Omeprazole is a proton pump inhibitor (PPI) that reduces stomach acid by blocking its production, and it can be used for heartburn, GERD, and ulcers. It is available both over-the-counter and by prescription. Sucralfate, on the other hand, is an antiulcer medication that forms a protective barrier over ulcers to help them heal, and it is only available by prescription. Omeprazole is typically taken once daily, while Sucralfate needs to be taken up to four times a day on an empty stomach. Omeprazole can cause side effects like headache and stomach pain, whereas Sucralfate's most common side effect is constipation. Additionally, Sucralfate can interact with many medications by attaching to them in the stomach, so you need to take other medications at different times. Both medications are available in generic forms.

  • Summary of Omeprazole vs. Carafate

    Summary for PPI

    Omeprazole (Prilosec) is a proton pump inhibitor (PPI). Over-the-counter (OTC) omeprazole (Prilosec) can ease heartburn, while the prescription version can treat gastroesophageal reflux disease (GERD) and other conditions involving too much stomach acid. Omeprazole (Prilosec) is taken by mouth, typically once daily 30 minutes before breakfast. Some of the more common side effects of omeprazole (Prilosec) include headache, stomach pain, and nausea. It's available as both brand name and generic medications.

    Summary for Antiulcer
    Prescription only

    Sucralfate (Carafate) is a prescription ulcer medication. It treats ulcers in the intestine (duodenal ulcers) in adults. Sucralfate (Carafate) is a protectant; the medication works directly at the site of the ulcer to protect it so it can heal. Although the medication helps ulcers heal, it isn't used to prevent future ulcers. Sucralfate (Carafate) comes in an oral suspension and tablets that are available as brand-name and generic versions. It's taken by mouth up to 4 times per day and it doesn't have many side effects since very little is absorbed from the gut.
