Clenpiq is a combination medicine that causes diarrhea for the purpose of cleaning your colon before a colonoscopy. Cleaning the colon allows the inside of your colon to be seen more clearly on the colonoscopy.

Clenpiq is for use in adults and children at least 9 years old.

Clenpiq may also be used for purposes not listed in this medication guide.

Clenpiq can cause severe dehydration, which can lead to a serious electrolyte imbalance, seizures, kidney failure, or abnormal heartbeats that can cause death.

The risk of dehydration is highest in people with heart problems or kidney disease, or if you take certain other medicines. Tell your doctor about all your current medicines and any you start or stop using.

Call your doctor if you are sick with vomiting and cannot drink enough water for your bowel prep, or if you have a headache, dizziness, or decreased urination.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

It is especially important to follow all instructions about what to eat or drink in the days before your colon prep.

You must dilute the powder form of Clenpiq with 5 ounces of cold water before taking it.

The oral solution (liquid) may be taken without adding water.

Do not eat solid food once you start taking this medicine. Stop drinking all fluids at least 2 hours before the colonoscopy.

You will need to drink extra water once you start your colon prep. Drink only clear liquids and avoid alcohol, milk, or any drink that is red or purple.
