You should take Dexilant for as long as your doctor prescribes it. Most people take Dexilant for 4 weeks to 6 months. Taking Dexilant long term may increase your risk of certain side effects. (For more details, see “Long-term side effects” in the “Dexilant side effects” section above.)
Talk with your doctor if you’re interested in taking Dexilant for longer than you were originally prescribed. They can determine if it’s safe for you to keep taking Dexilant or if you should switch to a different medication.
