Compare Prevacid vs. Maalox
Head-to-head comparisons of medication uses, side effects, ratings, and more.
Prevacid (lansoprazole) is an effective and inexpensive acid reducer commonly used to provide heartburn relief and help heal ulcers.
Maalox (aluminum / magnesium / simethicone) gives quick relief for heartburn, gas, and bloating, but it may not be as effective or last as long as other antacids.
- Most people can take Prevacid (lansoprazole) without any noticeable day-to-day side effects.
- Comes in a dissolving tablet to be placed on the tongue if you cannot or do not like to swallow pills.
- Prevacid (lansoprazole) lasts longer than other types of antacids (like Zantac, Pepcid, or Tums), and you only need to take it once a day.
- You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
- Prevacid (lansoprazole) is available over-the-counter and as inexpensive, generic options.

- 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).
