Laxatives are drugs that makes faeces soft and bowel movements easier. They can be used to lose weight, treat constipation or used to clear out still from the colon for a colonoscopy.

Coloprep can be used in treating constipation. It works by stimulating more water to be absorbed from the body to make the stools softer to be passed out. It can also help the muscles in the digestive tract to contract rhythmically so as to allow stool passage. It is recommended for people who are going for colonoscopy procedure.

A colonoscopy is a procedure that involves inspecting the colon for abnormalities, a flexible fibre-optic device is inserted into the rectum and the connected camera shows the inside of the colon. If there is stool in your colon, it will be difficult for the device to get the exact image of the tract. So to avoid repeating the procedure, coloprep is given to the patient prior to the appointment. The laxative clears out stools by retaining water and cleansing the intestines. 


Coloprep is usually prescribed and used as advised by the doctor. You should talk to your doctor if you are taking any other laxative or have other medical issues like bowel perforation, gastrointestinal blockage or even stomach retention. Read the instructions on the medicine package on how to take the medication.

However, coloprep is taken in two doses; the first dose is taken in the evening before the day of the colonoscopy procedure. The second dose is taken on the day of the procedure but at least 3 and half hours before the colonoscopy is done. The second dose is taken 10 to 12 hours after the first dosage. If the medicine is used for constipation treatment, the dosage is twice. One to be taken at anytime and the other to be taken 10 to 12 hours after. You can even add lemon juice to the medicine if you wish.
