I was scheduled for colonoscopy two years ago and was told to drink the Fleet soda prep. I TRIED AND TRIED to drink it but it just came back up and pretty soon the smell made me dry heave so the doc told me to forget it.

March 2 is round two w/a new GI doc. They use Movi Prep... BUT I'm worried that the same thing will happen--I am VERY sensitive to smells and taste. BUT I keep coming across that many member on this forum talk about using Miralax for a prep... REALLY?? HOW and WHY did your doc prescribe it?? Why wasn't that given to me as an option?? Did you have to use 'magical words' to convince your doc to let you try it?? I've been super sick for almost two weeks--totally blocked up, distended, pain in right side of stomach/tender... and used two doses close together yesterday to get things moving--finally--success..and then more success...yellow D 6 times in 1 1/2 hours. I don't know if that's normal for miralax...but wouldn't that be a good sign to the GI doc that Miralax could be an alternative if I can't get movi prep down??


I would love to hear ANY ideas!

I have never used Miralax, but when I told a previous Dr that I didn't think I would be able to keep the prep down (I was having SEVERE nausea during that flare) he allowed me to do a 3 day clear liquid diet and 2 fleet enemas, 1 the day before and 1 the day of the procedure. That Doc was cool though, the one I had recently wouldn't hear of it. That was about 12 years ago tho, give or take...
Dx'd w/ Crohn's in 1979 at age 14, have had minor flares throughout the years, but mostly kept in remission. Bad flare 2008 but no health insurance so I dealt with it. Colonoscopy in July 2009 caused a perforated colon, emergency bowel resection. Was on Pred. Dr. wants to try Humira...
Currently just take a multivitamin, calcium, magnesium, and fish oil.

For my son's first colonoscopy he had to use the Mag Citrate which he had a bad experience with (throwing up, lots of tears, and refusal to drink any more).  When it came time for his second one, I told his GI that he couldn't take the Mag Citrate and asked if there were any alternatives.  He was told to take Miralax mixed with gatorade.  It's one dose of Miralax mixed with 8 oz. of gatorade, every hour for 8 hours.  I think he also took Dulcolax the evening before he started with the Miralax.  Anyway, he's done this prep twice and it's been fine both times.  I don't know if it's different because he's a kid, but it wouldn't hurt to ask your GI about this prep.
Take care,

My last Colonoscopy they gave me the MOVIPREP solution which was a first as many previous were GoLitely. They are all pretty rough on the system, flavored now with somewhat tolerable flavorings, I think the lime is best, all are better chilled. Unfortunatley none are great, some just more bearable.
My first time (back in the dark ages, 1976) they gave me Mag Citrate and I had bad reaction, projectile vomit and dry heaving, etc. I now politely refuse and ask for alternates, which are usually the Movi or GoLite solutions.
Not sure what is recommended for children, should consult a physician and ask what alternatives are.

My daughter just had her second scope today.

Prep is easy.  2 Dulocolax tablets at 12 noon. Then starting at 3 pm, empty and entire 238 mg bottle of Miralax into an entire 64 oz. bottle of gatorade (no red or purple obviously). Drink that gatorade mixture over the next three hours, with the goal being to drink 8 oz every 15 minutes. If not cleaned out, take more Dulcolax.  That's it. Very simple. 

My daughter can't tolerate even the Gatorade so we used apple juice instead. She also can't drink that much liquid in such a short period of time, so we started her earlier in the day (about 12 noon with the juice), and the cleanout last longer (till about 6 pm till she was emptied out.) She did fine and was cleaned out after only about 4-5 trips to the bathroom. She's tiny so it was fast, but this same prep method was used by my husband when he had his scope last summer.

Hope this helps.

    last colonoscopy I used just the Miralax and Dulcolax tablets. I'm missing 3 feet of intestines - so I figure stuff moves thru pretty quick. No problems.... Miralax is much tastier - you mix it with Gatorade and is pretty tasteless. :-) good luck.

    Oh my gosh!!! You guys, thank you soooo much! I put a call into my doctor's nurse today and left a message asking about alternatives to nasty tasting stuff. But you guys were so helpful w/laying out a schedule. I pray that my doc is open to it!! I am so grateful for the information that I get from this forum!

    I just did miralax last friday for my colonoscopy prep. Basically same as what was mentioned above. Clear liquids the day before... 4 dulcolax at 3pm... at 5pm start drinking the 64oz bottle of gatorade/238mg miralax misture. 8oz every 10-15 mins for 60-90 mins. 4 hours before I left for the hospital, I drank the remaining 16oz of gatorade. I have a hard time drinking large amounts so it took me about 2 hours instead of the ideal 1 hour but I got it down.

    yay!! I'm still waiting for my doc's nurse to call me back to see if I can just do the miralax.. i hope my doc is down w/that.... WHY doesn't all docs do this?? it just seems like the EASIER on your stomach because it tastes much better... AND it's easier on your system. :D

    I have noticed with fleet prep it is good to do as a "shot", meaning in a shot glass.

    If it is any consolation I have used many different types of preps and that oral fleet crap is about as worse as it gets. I also threw it up and just the smell had me heaving and the nurse rolled her eyes at me (like i was the only person this had ever happened to!!). My Dr. that i have now uses a clear fluids diet started 2 days prior and then take pico salex 2 times the day before proceedure. It is just a packete mixed with a cup of water doesn't taste great but it isn't bad and can gulp it quick with your nose plugged and then drink down a bunch of water and its done lol. Its not as harsh on your system and some of the others are either.

    Once i had a really bad flare was bleeding badly hadn't eatten in days had nothing left in my system just water and blood coming out constantly and they made me do a prep im like why there is nothing there but i still had to do it.

    I'm not suggesting you go against your doctor's orders but they can't tell what you've used. They only care that you are cleaned out.

    I used to use a prep called Nutri-prep/Lo-so prep that included solid food. It was great for my hypoglycemia and it was easy. I used it for 6 colonoscopies plus my resection and other ab surgeries and procedures. My last GI refused let me use it even though I had pictures showing that it cleaned me out. Since I really needed the procedure, I just agreed to his prep and then did mine anyway.

    After the procedure the nurse said that I should be glad I used their prep because I was so clean. Since I was still loopy, I laughed and told her that I used my prep, not theirs. I told her I had problems with a liquid diet. She told me that it was funny how only fat patients had trouble staying away from food. Apparently, I then laughed at her and and started telling her in sailor language exactly what I thought of her. My husband almost smothered me getting me to shut up.

    I really use to struggle with the nauseating osmo prep... This time tried something different.
    I took two Ducolax tiny tablets at 3pm
    Mixed 238 gram bottle of Miralax into 64 ounces of Blue Gatorade
    Drank 8 oz every 10-15 minutes.
    Tasted fine, actually pretty plain Gatorade easy to tolerate
    Running clear ( actually green clear liquid, must be the Gaterade)by 2am ...just woke up, taking magnesium calcitrate and off to colonoscopy at 10:30
    Really, not too bad, but rather go to the beach!

    If I'm running clear, do I have to take the magnesium calcitrate?

    Honeycrisp does the same thing i do. I get 2 32oz bottles and pour half of the miralax into each. Taste really doesnt change. The only thing is it becomes a bit thicker. But totally tolerable. .

    I've been having colonoscopies every 2 years since I was in my 20's(I'm 55 now) The only prep I've been able to do is the mag citrate prep. I tried the miralax once but it was just too much to drink in such a short time and it gave me chills for hours. Having another one done next week. The preps have changed quite a bit over the years. I can barely get down one bottle of the mag citrate, but I rub lemon on my tongue before each gulp. That seems to help. Seems now, the doctors want you to do 2 bottles. Hmm, I don't think so. 1 has worked for me all these years. don't see a reason to change. I also take a couple of dulcolax tablets a few hours after I drink the mag citrate. It does seem to take longer and last longer for me though. I don't get much sleep the night before.

    I've found a way that helps with the nasty taste - it doesn't completely disappear, but it helps. :)

    I pour an 8-oz glass at a time and try to gulp it in 4 big gulps in quick succession, while holding my nose the entire time and standing in front of the sink (just in case, yo!)

    While still holding my nose, I take a big gulp of something sweet & carbonated (I like to use Coke), swish it around in my mouth and spit it in the sink.

    While STILL holding my nose, I put a hard candy (not red or purple!) in my mouth and suck on it for about 20 seconds before I let go of my nose. Between the sugary soda rinse and the taste of the hard candy, the nasty prep taste is usually completely gone. The hardest part is gulping it down....even with your nose plugged, you can sometimes taste it just a little, but it's way better than doing it unplugged!
