Relieves heartburn and excess stomach acid, and treats ulcers.

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

Relieves symptoms of indigestion and pain

Alka-Seltzer (aspirin / citric acid / sodium bicarbonate) provides quick relief for heartburn, upset stomach, headaches, and general pain. However, you have to take it a few times a day to continue getting relief of your symptoms.

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.
  • Alka-Seltzer (aspirin / citric acid / sodium bicarbonate) is a great option if you have an upset stomach and a headache or body aches at the same time.
  • Alka-Seltzer (aspirin / citric acid / sodium bicarbonate) works quickly to relieve symptoms.
  • Available over the counter without a prescription.
  • Also, available as generic and is fairly cheap.
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.
  • The effects of this medication don't last very long. Other medicines, like Zantac (H2 blockers) and omeprazole (proton pump inhibitors), work better and last longer.
  • Because this medicine contains aspirin, it raises the risk of bleeding, especially if you take any other blood thinning medicines.
  • People who are allergic to aspirin can't use this medication.
  • May not like the taste or fizz.
  • Kids or teenagers should not use Alka-Seltzer (aspirin / citric acid / sodium bicarbonate) unless instructed by a doctor.
