LINZESS™ (linaclotide) is a prescription medication used in adults to treat irritable bowel syndrome with constipation (IBS‑C) and chronic idiopathic constipation (CIC). "Idiopathic" means the cause of the constipation is unknown. It is not known if LINZESS is safe and effective in children.
LINZESS can cause serious side effects, including diarrhea, the most common side effect, which can sometimes be severe. Diarrhea often begins within the first 2 weeks of LINZESS treatment. Stop taking LINZESS and call your doctor right away if you get severe diarrhea during treatment with LINZESS.
Other common side effects of LINZESS include gas, stomach‑area (abdominal) pain, swelling, or a feeling of fullness or pressure in your abdomen (distension). Tell your doctor if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of LINZESS. For more information, ask your doctor or pharmacist.
In addition, call your doctor or go to the nearest hospital emergency room right away if you develop unusual or severe stomach‑area (abdominal) pain, especially if you also have bright red, bloody stools or black stools that look like tar.
Take LINZESS exactly as your doctor tells you to take it. Take LINZESS one time each day on an empty stomach, at least 30 minutes before your first meal of the day. Swallow LINZESS capsules whole. Do not break or chew the capsules.
Store LINZESS at room temperature (68ºF to 77ºF), and keep LINZESS in the bottle it comes in. Keep the LINZESS bottle tightly closed, in a dry place, and keep the desiccant packet (the drying agent) in the bottle. Keep LINZESS out of the reach of children.
