Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
How long after I take 10 milligrams of Dulcolax by mouth will it work? I have to take this two days before my colonoscopy then on the next day I have to prepare Pico Salax. One I drink in the morning and the other in the evening. Does the Dulcolax work right away or over night?
