Drug class

PPIs

Also called Proton pump inhibitors

Reduce stomach acid for heartburn, GERD, and ulcers.

How it works

PPIs shut down the 'pumps' in stomach-lining cells that release acid. With less acid in the stomach, irritation and ulcers can heal.

What it treats

GERD (chronic heartburn), peptic ulcers, H. pylori treatment (with antibiotics), erosive esophagitis.

Common side effects

Headache, abdominal pain, diarrhea, gas. Long-term use is linked to lower magnesium, B12 deficiency, and a small increase in fracture risk.

Worth knowing

Generally meant for short courses (2–8 weeks) unless a prescriber tells you otherwise.
