Our pharmacists’ bottom line
Pepcid (Famotidine) works well for heartburn but may not last as long or start working as quickly as other antacids.
- Most people can take Famotidine without any noticeable day-to-day side effects.
- Famotidine lasts longer than many other antacids like Maalox and Tums, and you only need to take it once or twice a day.
- You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
- Available as both a generic and over-the-counter option, so it's pretty affordable.
- Few drug interactions.
- 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).
- Can cause more serious side effects for people with kidney disease. Ask your doctor to give you a lower dose or choose a different option.
