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.
  • Lasts longer than other medicines like it so you may not need to take it as frequently.
  • Affordable as an over-the-counter or generic medicine.
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.
  • Does not work as fast as antacids like Maalox, Tums, or Rolaids.
  • May not work as well if you have an inflammed esophagus. Your doctor will assess which medicine is best for you.
  • May not be the best option if you are elderly or have kidney or liver problems.
  • Can interfere with how other medicines work.
