Buying Guide

Identify active ingredient

Choose based on mechanism—PPIs (omeprazole, lansoprazole) reduce acid production, H2 blockers (famotidine) limit acid release, and antacid minerals neutralize stomach acid for quick relief

Match onset and duration

Use antacids or H2 blockers for faster, short-term relief and delayed‑release PPIs for longer-lasting control of frequent or chronic symptoms

Check dosage form

Select tablets, chewables, or disintegrating forms based on swallowing ability and whether you need on-the-go chewable relief or scheduled delayed-release dosing

Consider safety and interactions

Review potential drug interactions and speak with a clinician if you take other medications, have kidney disease, or require long-term therapy

Flavor, additives, and dietary fit

If you prefer flavored chewables or sugar-free options, check ingredient lists for sweeteners, flavors, and minerals like calcium or magnesium
