  • 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.

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.

  • May not be the best choice for patients 65 years of age and older due to risk of bone fractures and C. diff infection (bacterial).
