Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with plecanatide and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests to check your body's response to plecanatide.
Talk to your doctor about the risk(s) of taking plecanatide.
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.
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.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

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. Web Site
