Zegerid (omeprazole and sodium bicarbonate) is an effective medicine for heartburn, but it's more expensive than buying omeprazole by itself.

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.
  • Prilosec (omeprazole) lasts longer (up to 72 hours) than other classes of acid reducers (like Zantac, Pepcid, or Tums).
  • Only take once or twice daily.
  • Can take together with a quick-acting antacid (like Maalox or Tums) for quick relief.
  • Generic and over-the-counter options available.
  • Safe to use in children ages 1 or older.
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.
  • Takes up to an hour to start noticing the effects of Prilosec (omeprazole).
  • Prilosec (omeprazole) can interact with other drugs. Let your doctor and pharmacist know what medications you're taking before starting Prilosec (omeprazole).
  • Long-term use of Prilosec (omeprazole) can put you at risk for many health issues such as osteoporosis, low magnesium or vitamin B12 levels, and rebound acid secretion (where your body starts to create more acid than before after stoping Prilosec (omeprazole)).
