Antacids

Chewable tablets and liquid antacids provide fast, short-term relief of heartburn by neutralizing stomach acid; H2 blockers (e.g., famotidine) reduce acid production for several hours and are better for recurring symptoms; proton pump inhibitors (PPIs) reduce acid production more strongly and are intended for frequent or chronic symptoms under guidance from a healthcare provider

Check active ingredients and dosages, look for warnings about interactions with prescription drugs, verify suitability for pregnancy or existing kidney disease, and avoid products containing sodium if you need a low-sodium diet; when in doubt, consult a pharmacist or clinician

Fastest relief typically comes from liquid antacids and chewable tablets that neutralize acid within minutes, H2 blockers take 30–60 minutes and last several hours, while PPIs may take days to reach full effect but provide longer-term control for frequent symptoms

Over-the-counter antacids and H2 blockers are commonly available at lower price points, while branded or specialty formulations and PPIs (often sold as longer courses) tend to cost more; shoppers can expect a range from budget options under $20 to higher-priced or specialized supplements and formulas averaging higher

Store antacids in a cool, dry place away from direct sunlight and moisture; check the package for expiration dates—effectiveness can decline after expiration—discard if texture or smell changes

Yes—antacids and acid-reducing drugs can alter absorption of certain medications (including some antibiotics, iron supplements, and antifungals); separate dosing times when advised and consult a pharmacist or prescriber about specific interactions

See a healthcare provider if symptoms are severe, persistent or recur more than twice a week, if you have difficulty swallowing, unexplained weight loss, vomiting, black stools, or if over-the-counter products provide little or no relief
