Wait for prep 2 work: The purpose of the liquid prep (which everyone agrees tastes really awful) is to clean out your colon so the dr using scope can see clearly during the exam. It is designed to cause successive bouts of diarrhea, until you can't go any more. If you only vomited up a little, it may still work as designed. If you don't experience results, call and reschedule the exam. They may give you a diff prep ...Read more

AlwaysAGuess; agent,: dose & response relationships with all the usual complex individual variables. A full bottle of citrate of magnesia will likely be far more effective than the other agents, especially if one stays physically active, fasts, take 2 days prior & chase with another bottle 1 day prior. Just keep up clear liquids. Awareness of heart beats both a focus & a self-distraction (from other greater) issues. ...Read more

Mag Citrate: Several options: chill and drink slowly. Have hot coffee/tea before to get intestines simulated in the correct direction. Use MiraLAX (polyethylene glycol) the morning of and/or day before, again to get the tract flowing easily. ...Read more

Took 400mg of presc magnesium this am before starting colonoscopy prep. Noticed suprep has magnesium. Is it ok that i took magnesium supplement.

Probably ok: The magnesium supplement you took was probably eliminated during the bowel cleansing process, which uses a magnesium-based laxative such as magnesium citrate. The magnesium in the bowel prep isn't absorbed by the body but passes through the intestines and causes the bowel-cleansing cathartic effect. Check with your pcp or gastroenterologist. ...Read more

I took milk of magnesia (magnesium hydroxide) 6 hours ago to start colonoscopy prep, and it hasn't worked yet. I have not been constipated. What's wrong?

Not enough: MOM is only used for constipation and is inadequate as a preparation for colonoscopy. You may have been told to take Magnesium Citrate but even this is not usually enough. Call your doctor's office for their recommendation ASAP. ...Read more

Drank 10oz of magnesium citrate 4.5 hrs ago and still nothing. How long does it take? (It's for a flex sig prep)

Depends on whether: you are constipated and not drinking enough caffeine free/alcohol free fluid. Try some enemas to clear out any stool in your rectum. Do not take any more Mag Citrate without talking with your doctor first. May need to reschedule your scope. ...Read more

Surgery prep says take one bottle of magnesium citrate. bought milk of magnesia (magnesium hydroxide). Same or different?

Different: Magnesium citrate is different than milk of magnsesia. Look for citrate in a colored glass bottle usually. Ask the pharmacist if you cannot find it. It is a clear liquid and will cause BM fairly soon after you ingest it so I advise to take it at home. Milk of magnesia (magnesium hydroxide) will also cause a bowel movement but not as rapidly. ...Read more

Does magnesium citrate for a bowel prep cause water retention? Or just help clean the bowel out?

Does magnesium citrate for a bowel prep cause water retention? Or just help clean the bowel out?

Magnesium Citrate: Magnesium citrate retains water in the intestines by osmosis. Increasing water in the bowel aids motility, usually producing a bowel movement within one-half to six hours. Magnesium Citrate does not cause water retention. ...Read more
