Linzess (linaclotide) is a prescription medicine used to treat constipation-related bowel problems. It is approved for adults with irritable bowel syndrome with constipation (IBS-C) or chronic constipation, and for children and teens ages 6 to 17 with functional constipation. Linzess works by increasing fluid in the intestines, which softens stools, makes bowel movements easier, and helps reduce stomach pain linked to IBS-C.
Take Linzess on an empty stomach at least 30 minutes before the first meal of the day. Swallow the capsule whole with water. Don't break, chew, or open it. Take the medication at around the same time each day.
Standard dosing varies by condition:
For those with trouble swallowing capsules, the capsule can be opened and the contents mixed with applesauce or water. When mixing with applesauce, use 1 teaspoon and swallow it immediately without chewing. When mixing with water, add the contents to approximately 1 ounce of room temperature water, gently swirl for at least 20 seconds, and drink the mixture. It may be recommended to add another ounce of water to the cup, swirl it, and drink it to ensure the full dose is taken.
Linzess should be taken exactly as directed without adjusting the dose unless a healthcare provider recommends it. Store the capsules at room temperature in their original container with the desiccant inside to protect them from moisture.
Linzess contains linaclotide as its active ingredient.
Avoid taking or using this medication if any of the following apply:
Common side effects of Linzess include:
Diarrhea is the most common side effect and often starts within the first two weeks of treatment. While it is usually manageable, it can sometimes be severe. Stop taking Linzess and contact your healthcare provider if you develop severe or persistent diarrhea.
More serious symptoms need urgent medical attention. Call your healthcare provider or go to the emergency room if you have severe or unusual abdominal pain, especially if it occurs with bright red blood in the stool or black, tar-like stools.
What is Linzess (linaclotide)?
Linzess is a prescription medication that contains linaclotide and is used to treat certain chronic bowel conditions. It works locally in the intestines to help improve bowel movements and reduce abdominal discomfort.
What conditions is Linzess used to treat?
Linzess is approved to treat irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in adults. These conditions involve ongoing constipation that is not caused by another medical disease.
How does Linzess work in the body?
Linzess increases fluid secretion in the intestines and speeds up the movement of stool through the digestive tract. It also helps reduce pain signals from the gut, which can relieve abdominal pain associated with constipation.
How is Linzess usually taken?
Linzess is typically taken once daily on an empty stomach, at least 30 minutes before the first meal of the day. The capsule should be swallowed whole and not crushed or chewed.
How long does it take for Linzess to start working?
Some people may notice improvement in bowel movements within the first week of treatment. Relief of abdominal pain and bloating may take longer and can continue to improve with consistent use.
What are the most common side effects of Linzess?
The most common side effect is diarrhea, which can sometimes be severe. Other possible side effects include abdominal pain, gas, bloating, and stomach discomfort.
What should I do if Linzess causes severe diarrhea?
If severe or persistent diarrhea occurs, the medication is usually stopped and a healthcare provider should be contacted. Dehydration and dizziness can occur if diarrhea is not addressed.
Who should not take Linzess?
Linzess should not be used in children under 2 years of age due to the risk of serious dehydration. It is also not recommended for people with known or suspected bowel obstruction.
Can Linzess be taken long term?
Linzess may be used long term if it remains effective and well tolerated. Ongoing use should be monitored by a healthcare provider to assess symptom control and side effects.
Does Linzess interact with other medications or foods?
Linzess has minimal drug interactions because it works mainly in the gut and is not significantly absorbed into the bloodstream. Taking it with food may increase the risk of diarrhea, which is why it is recommended on an empty stomach.
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (e.g., different shape or color), as trademark laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
