Upsides
  • Relieves heartburn symptoms and heals ulcers better than other stomach medicines, such as Pepcid, Tagamet, and Zantac.
  • Lasts longer than other similar stomach medicines. Most people take it once a day.
  • Your body won't develop a tolerance to Dexilant (Dexlansoprazole), so it'll work the same way as long as you need to keep taking it.
  • Once heartburn symptoms are treated, a low dose of Dexilant (Dexlansoprazole) can be taken daily.
  • 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.
Downsides
  • Taking Dexilant (Dexlansoprazole) in high doses or for longer than 1 year can increase the risk for bone fractures, especially if you already have osteoporosis (weak bones).
  • Many drugs can interact with Dexilant (Dexlansoprazole), so talk to your doctor or pharmacist before starting any new medicines.
  • There's no generic version available, so it can be expensive.
  • 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.
