Linzess (linaclotide)

What are the Indications for Linzess?

Linzess is primarily used to treat irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). IBS-C is a condition that causes abdominal pain and discomfort, along with constipation and infrequent bowel movements. CIC, on the other hand, is a chronic condition characterized by difficulty passing stools, infrequent bowel movements, and abdominal discomfort.

Linzess is not recommended for use in children under the age of 2, if you have a bowel blockage, or if you are allergic to any of its ingredients.

How is Linzess used?

Storage

Linzess should be stored at room temperature between 68° – 77°F(20° – 25°) in a tightly closed container, away from light and moisture.

Keep out of reach of children and pets.

Instruction

Linzess should be taken on an empty stomach at least 30 minutes before the first meal of the day, as directed by your doctor. The capsule should be swallowed whole with water and should not be broken or chewed.

If you are unable to swallow the capsule, the capsule can be opened and poured into a mixture of applesauce or water for easier consumption. The mixture must be consumed right away. Do not mix and use at a later time.

If the medication needs to be administered through a feeding tube, the capsule can be opened and poured into a clean cup with 30 mL of water. Carefully mix the medication for 20 seconds and administer it with the use of a syringe. If there is any medication left over in the cup, an additional 30 mL of water can be added to the cup and administered with the syringe again. Flush the feeding tube with water.

Dosage

Linzess is available in capsule form in the following strengths: 72 mcg, 145 mcg, and 290 mcg.

For irritable bowel syndrome with constipation (IBS-C), the recommended dose of Linzess is 290 mcg once daily.

For chronic idiopathic constipation (CIC), the recommended dose is dependent on tolerance and can be either 72 mcg or 145 mcg once daily.
