I have a colonoscopy tomorrow. i took my bowel prep of about an hour ago. in how much time will it start working? will a gatorade/miralax mix not work?

A couple of hours: There are a variety of different bowel preps, some more aggressive than others. In general, these start to work after a couple of hours. The gatorade/miralax is a bit more gentle. The goal is to get things cleaned out by the morning.

A few hours: Usually takes a few hours.

By the time you read: Will need short 2 hrs to start to work , and complete by the time you see your doctor you will be clean for the procedure. ( if you took it properly as instructed ) , .

May not work: A gatorade and MiraLAX combination is not a common bowel prep in my experience. Miralax is an excellent laxative but if only one dose is taken, it is not likely to clean the colon out as well as is optimal for colonoscopy. A single dose might not produce a bm for a day or 2. Gatorade is an electrolyte-rich drink but not likely as effective as GoLytely or other polyethylene glycol solutions.
