Upsides
  • 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.
  • Works quickly.
  • Inexpensive and available over-the-counter.
  • Is one of the first choice medications for heartburn relief if you are pregnant.
Downsides
  • Doesn't start working right away like some other acid reducers (Tums, Rolaids, or Maalox).
  • 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).
  • Is used if you have frequent heartburns that occur more than 2 days per week. Speak to your doctor or pharmacist if you only have occasional heartburn.
  • Doesn't last very long. Talk to your doctor or pharmacist if you need longer lasting relief.
  • Is not a good option if you have frequent symptoms (more than 2 times a week). Talk to your doctor or pharmacist about stronger medications.
