Telotristat

Telotristat is used in combination with another medication (a somatostatin analog [SSA] such as lanreotide, octreotide, pasireotide) to control diarrhea caused by carcinoid tumors (slow-growing tumors that release natural substances that can cause symptoms like diarrhea) in patients with diarrhea not controlled by a somatostatin analog alone. Telotristat is in a class of medications called antidiarrheal agents. It works by blocking the formation of a certain natural substance in the body that is released by the carcinoid tumors and causes diarrhea.

Telotristat comes as a tablet to take by mouth. It is usually taken with food three times a day. Take telotristat at around the same times 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 telotristat exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take while taking telotristat. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

• tell your doctor if you have or have ever had liver disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking telotristat, call your doctor. If you are breastfeeding while taking telotristat, call your doctor if you child becomes constipated.
