Also, point out if he/she has any heart, kidney or liver disease, or for those who have had these diseases in the past. Patient has to mention any allergies he/she has with medicines to the physician. For those who have had difficulty with bowel prep previously, be sure to mention this too.

Bowel Prep Medications
Polyethylene glycol; Electrolytes oral solution may come as a powder to be combined with water before use. They are available only by doctor prescribed and are taken by mouth. Although given in a greater volume than other items used in bowel prep, PEG-based products are often preferred for patients with kidney, heart and liver conditions. The reason is that they do not cause mineral or fluid changes that can lead to dehydration. Sodium phosphate comes in tablet form to be taken by mouth as well as a prescription. In rare cases, sodium phosphate can cause kidney failure. Physicians consider this when deciding if sodium phosphate is appropriate for any given patient.
Understanding Bowel Preparation before Colonoscopy
It is extremely essential that patient’s colon be thoroughly cleaned before colonoscopy. This can allow physician see any abnormalities, such as colon polyps, throughout the procedure. Polyps are small growths in the colon that may later become cancer. Cleansing the colon before a colonoscopy is called bowel preparation, or “prep.” It calls for taking medicine that triggers diarrhea, emptying the colon. The drugs are taken orally, and are available in liquid or tablet form. Additionally, patient will need to change that which he/she eat during the day or two prior to the colonoscopy.
