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?

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?

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. ...Read more

I took miralax prep for colonoscopy tomorrow..also 4 stool softeners as directed along with the broth jello diet..started the cleanse at 4 p.m. still ?

May take awhile: Hi BShetty, The bowel prep for a colonoscopy can be very challenging to take. Because the goal is to clear your colon of stool completely, the regimen is very aggressive and you may be having bowel movements almost continuously until it is just clear liquid coming out. Depending on the regimen, you may also experience residual cramping as the effects of the laxative wear off. Hope this helps. ...Read more

I have drunk miralax (polyethylene glycol) all day ever 2/3 hours because I'm getting an endoscopy and colonoscopy tomorrow, but I just threw up a lot is this bad?

Lot of miralax (polyethylene glycol): Regurgitating too much miralax (polyethylene glycol) is not uncommon if the stomach gets overloaded and cant handle the volumn injested. I prefer GoLightly which adsorbs fluid into the small bowel and secondarily cleanses the colon. In spite of everything I still suggest a Fleet enema before going for the procedure. ...Read more

Best to : Discuss this with your GI doctor or colon and rectal surgeon who will be performing the procedure. Try drinking less caffeine and more fluid to 80 ounces per day or more and you will probably not need the MiraLAX (polyethylene glycol) any longer. ...Read more
