What is Dexilant for?

Dexilant is a brand product that contains Dexlansoprazole, which is a type of acid-reducing drug. It works by blocking proton pumps in the stomach to inhibit the production of stomach acid.

Capsules should be swallowed whole. If you have trouble swallowing Dexilant capsules whole, you can open the capsules and sprinkle the contents on a tablespoon of applesauce.
