Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Linzess (linaclotide) and Motegrity (prucalopride) are both used to treat chronic constipation, but they work in different ways and have some key differences. Linzess is a guanylate cyclase-C (GC-C) agonist that increases fluid in the intestines to help with bowel movements and is taken on an empty stomach once a day. Motegrity, on the other hand, is a serotonin-4 receptor agonist that stimulates gut movement and can be taken with or without food once a day. Both medications are available as brand only medications. Common side effects of Linzess include diarrhea and stomach pain, whereas Motegrity often causes headaches and nausea. Additionally, Motegrity has a warning for potential mood changes and suicidal thoughts, which is not a concern with Linzess. Both medications should be taken consistently, but you should consult your healthcare professional to determine which is best for you.
