What are proton pump inhibitors?
Proton pump inhibitors (PPIs) are a group of prescription medications that prevent the release
of acid in the stomach and intestine. Doctors prescribe proton pump inhibitors to treat people
with heartburn (acid reflux), ulcers of the stomach or intestine, or excess stomach acid
PPIs include Aciphex® (rabeprazole), Prevacid® (lansoprazole), Prilosec® (omeprazole), Nexium® (esomeprazole) and Protonix® (pantoprazole).Most people tolerate proton pump inhibitors well with few side effects. The most common side effects include mild dizziness, headache, nausea, diarrhea, constipation, and rash. Rare side effects are breast enlargement in men and anemia.
