Compare pantoprazole vs. Alka-Seltzer

Head-to-head comparisons of medication uses, side effects, ratings, and more.

Treats heartburn and excess release of stomach acid.

Protonix (pantoprazole) is usually only taken once a day for long-lasting heartburn relief, but it can increase your risk of bone fractures if you've used it for a long time.

3.8/ 5 average rating with 584 reviewsforpantoprazole
Relieves heartburn, headache, and body pains.

Alka-Seltzer Original (Aspirin / Citric Acid / Sodium Bicarbonate) gives quick relief for headache, body pains, and upset tummies, but might be hard to swallow if you don't like the taste or fizz.

Upsides
  • Most people can take Protonix (pantoprazole) without any noticeable day-to-day side effects.
  • Protonix (pantoprazole) 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 with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
  • Unlike other proton pump inhibitors, it can be taken with or without food and have the same effectiveness.
  • Can be used in children age 5 or older.
  • Works great if you have an upset stomach and a headache or body pain at the same time.
  • Works really fast.
  • Available over the counter without a prescription.
  • Cheap.
Downsides
  • Doesn't start working as fast as some other antacids like Tums, Rolaids, or Maalox.
  • Needs to be taken every single day for a certain period of time to be effective.
  • Like with other proton pump inhibitors, long-term use can cause weak or broken bones.
  • Only available as a prescription medicine, not over the counter.
  • Can lower the magnesium level in your body so you may need to take a supplement for it.
  • Doesn't last very long.
  • Other antacids like Zantac (H2 blockers) and omeprazole (proton pump inhibitors) can work better and last longer.
  • Because it has aspirin in it, it increases the risk of bleeding, especially if you take any other blood thinning medicine.
  • Can't be used by people with allergy to aspirin.
  • You may not like the taste or fizz.
