In this session, we will be discussing the consumer medication information for linaclotide, trade name LinzessTM.

What it’s for & How to take

Linaclotide is used to treat irritable bowel syndrome associated with constipation as well as a condition known as chronic idiopathic constipation. This type of constipation refers to infrequent passage of stool that lasts for 3 months or longer, and the cause is not immediately known.

Linaclotide works by causing an increase in movement of food and waste through the stomach and intestines by increasing intestinal fluid and motility.

Linaclotide is usually taken once daily, on an empty stomach, at least 30 minutes before the first meal of the day. This medication comes as a capsule that is meant to be swallowed whole. Do not chew or crush the capsule.

Linaclotide is available in 2 different dosages. Your dose is based upon your specific clinical condition and response to therapy. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Your constipation symptoms may improve within 1 week; however, it may take longer for your irritable bowel symptoms to improve. Remember, this medication only treats the symptoms of constipation, it does not treat the condition that caused the problem.
