Why is this medication prescribed?
Plecanatide is used in adults to treat chronic idiopathic constipation (CIC; difficult or infrequent passage of stools that lasts for 3 months or longer and is not caused by a disease or a medication) and irritable bowel syndrome with constipation (IBS-C; a condition that causes stomach pain or cramps, bloating, and constipation.) Plecanatide is in a class of medications called guanylate cyclase-C agonists. It works by increasing the movement of food and waste through the stomach and intestines.
How should this medicine be used?
Plecanatide comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take plecanatide at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take plecanatide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split or chew them.
If you are unable to swallow the tablets, you can crush and mix them with water or applesauce. Do not mix the tablets with other liquids or other foods. Be sure to ask your pharmacist or doctor if you have any questions about how to mix or take this medication.
- To mix the tablet with applesauce, crush it into a powder and combine with 1 teaspoonful of room temperature applesauce. Swallow the entire mixture immediately; do not store the mixture for later use.
- To mix the tablet with water, place the tablet in a clean cup and add 30 mL of water at room temperature. Mix by gently swirling the mixture for at least 10 seconds. Swallow the entire mixture immediately. If any portion of the tablet is left in the cup, add another 30 mL of water to the cup and swirl for at least 10 seconds; then swallow the mixture immediately. Do not store the mixture for later use.
- If you have a feeding tube, the tablets can be crushed and mixed in water and given through the feeding tube. Ask your doctor or pharmacist how you should take the medication. Follow those directions carefully.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Remove and discard the polyester coil (used to protect the tablets during shipping) after opening the bottle. Do not remove the desiccant (drying agent) from the bottle, if one has been provided.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
