This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Dexlansoprazole comes as a delayed-release (releases the medication in the intestine to allow some of the medication to be released about 1 hour after it is taken and some of the medication to be released 4 to 5 hours later) capsule to take by mouth. It is usually taken once a day. Dexlansoprazole may be taken with or without food. Take dexlansoprazole at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dexlansoprazole exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.

Swallow the delayed-release capsules whole; do not chew or crush them. If you have difficulty swallowing capsules, you may open the capsule, sprinkle the contents on 1 tablespoon of applesauce, and swallow immediately without chewing. You can also open a capsule and pour the contents into 20 milliliters of water; using an oral syringe, draw up the entire amount, shake the syringe gently, and squirt the contents into your mouth immediately. Then draw an additional 10 mL of water into the syringe, shake gently, and squirt that water into your mouth.

The capsule contents can be given through a feeding tube. If you have a feeding tube, ask your doctor how you should take the medication. Follow these directions carefully.

Continue to take dexlansoprazole even if you feel well. Do not stop taking dexlansoprazole without talking to your doctor. If your condition does not improve or gets worse, call your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
