Worth it?Is it worth it?
Works well?Does it work?
Hassle?Is it a hassle?
  • 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 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.
  • In studies it was better than a placebo (sugar pill) and as good as other proton pump inhibitors at treating heartburn.
  • Available as both a generic and over-the-counter option, so it's pretty affordable.
  • Doesn't start working as fast as some other antacids like Tums, Rolaids, or Maalox.
  • Like with other proton pump inhibitors, long-term use can cause weak or broken bones.
  • Can cause low levels of magnesium in the blood. You might need to take a magnesium supplement if you use Zegerid long-term.
  • Although the generic is affordable, other medications might still be cheaper than Zegerid.
  • Can interact with other drugs so be sure your doctor knows all the medicine you're taking before starting Zegerid.
