Buying Guide

Know the drug class

Understand whether you need a proton pump inhibitor (omeprazole, lansoprazole) or an H2 blocker (famotidine, ranitidine alternatives) — they differ in onset, duration, and typical use

Match formulation to use

Choose delayed‑release tablets like omeprazole or lansoprazole for daily acid control and chewable or immediate‑action tablets for quick heartburn relief

Check active ingredient strength

Compare milligram doses (for example omeprazole 20 mg or famotidine 20 mg) to ensure you’re selecting an appropriate potency for your symptoms

Review additional ingredients

Note non-medicinal components such as calcium or magnesium in chewables and flavoring agents if you have sensitivities or dietary restrictions

Consider package size and value

Evaluate tablet count and dosing instructions to estimate how long a bottle will last and whether the unit cost fits your budget under $50
