How Linzess (linaclotide) works
Linzess (linaclotide) is a guanylate cyclase-C (GC-C) agonist. GC-C is a protein that works in the intestines.
Linzess (linaclotide) turns on the GC-C protein. This raises the amount of fluid in your intestines and speeds up the movement of food through your gut. These actions help you have regular bowel movements and possibly relieve belly pain.

Pharmacist tips for Linzess (linaclotide)
- Take Linzess (linaclotide) on an empty stomach, at least 30 minutes before a meal. It's a good idea to take the medication at about the same time each day. This helps make it a part of your everyday routine so you remember to take your medication.
- If you forget to take a dose of Linzess (linaclotide), skip the missed dose. Wait to take your usual dose the next day. Don't take two doses at the same time. This can cause stomach upset or diarrhea.
- Swallow the Linzess (linaclotide) capsule whole. Don't crush or chew the capsule or the beads inside. Talk to your prescriber if you have trouble swallowing it whole; there might be other options for you.
- Diarrhea is a common side effect of Linzess (linaclotide). It most often starts within the first 2 weeks of starting the medication. Drink plenty of fluids while taking Linzess (linaclotide). This helps prevent dehydration from any diarrhea that you have.
- Stop taking Linzess (linaclotide) and get medical help right away if you have severe diarrhea. Other signs to be aware of include sudden stomach pain and stool that’s bright red or black like tar. Also get medical help right away if you feel dizzy, very tired, faint, or confused. These could be signs of serious dehydration. You should get checked out by a healthcare professional and get treated if needed.
- Keep Linzess (linaclotide) in the original bottle. Don't remove the desiccant packet that's included because it keeps your medication dry. Store Linzess (linaclotide) in a dry place at room temperature.
Tips for taking Linzess (linaclotide) if you have trouble swallowing or have a feeding tube:
- You can open the Linzess (linaclotide) capsule. Then, sprinkle the beads on room-temperature applesauce or bottled water. Follow the instructions carefully, since they're different for applesauce and water. Don't use other foods or liquids since we don't know how they affect the medication.
- Once prepared, swallow the medication right away without chewing the beads. Don’t save any leftover mixtures for later. It might not be safe to take after it's left out for some time.
- If you have a feeding tube, follow the directions to prepare and take Linzess (linaclotide). Open the capsule and pour the beads into a clean container. Mix the beads with room-temperature bottled water. Then, use a syringe to draw up the mixture and put it through the feeding tube as directed.
- If you mix the beads from the capsule with bottled water, you’ll get your full dose of Linzess (linaclotide). This is true even if the beads stay in the cup or if you can't flush them through the feeding tube. The beads won’t disappear in the water. But the medication is on the outside surface of the beads and dissolves into the water.
