Relieves heartburn.

Pepcid (Famotidine) works well for heartburn but may not last as long or start working as quickly as other antacids.

Upsides
  • Most people can take Zegerid without any noticeable day-to-day side effects.
  • Zegerid lasts longer than other types of antacids (like Zantac, Pepcid, or Tums), and you may only need to take it once a day.
  • Contains both a quick acting and a long acting component to help provide fast and long lasting relief.
  • Is inexpensive as both generic and over-the-counter options are availabe.
  • 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.
Downsides
  • Zegerid (omeprazole and sodium bicarbonate) contains sodium bicarbonate which isn't good if your doctor's asked you to lower your sodium bicarbonate or if you have heart or blood pressure problems.
  • May not be the best option if you have Bartter's syndrome due to sodium bicarbonate. Speak to your doctor first.
  • Should not be used for occasional heartburns. Talk to your doctor or pharmacist about other medications if you do not have frequent heartburns.
  • 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.
