Downsides

  • Other antacids like Maalox, Tums, or Rolaids often start to work more quickly than Famotidine.
  • Medication like omeprazole (proton pump inhibitors) works better at healing and preventing stomach ulcers than medication like Famotidine (H2 blockers).

How it works

Pepcid (Famotidine) is a type of antacid called an H2 blocker. It blocks the chemical histamine, which lowers acid production in your stomach. This treats heartburn and helps ulcers heal.
