Upsides
  • 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.
  • Works quickly.
  • Inexpensive and available over-the-counter.
  • Is one of the first choice medications for heartburn relief if you are pregnant.
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).
  • 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.
  • Doesn't last very long. Talk to your doctor or pharmacist if you need longer lasting relief.
  • Is not a good option if you have frequent symptoms (more than 2 times a week). Talk to your doctor or pharmacist about stronger medications.
