How long do the effects of Magnesium citrate last?

Hi, looking to take about 15oz. of Magnesium Citrate at 7 or 8 am and wanted to know how long the effects last for. Has anybody used this stuff before? I'll be fully diapered of course! I used it awhile back but can't remember how long it last for. Thanks in advance

Cheers

Hi. Expect it to kick in after about two hours on an empty stomach, (nothing to eat since the night before). It will generally last about two hours but some people have results many hours later. In the future you can take a single Dulcolax tablet with magnesium Citrate and it will get done faster once it kicks in.

Had a hernia operation last week. The pain killers TOTALLY stopped all bowel movement. My daughter bought a bottle and I drank it before bed. Actually did little to help. Lots of bowel sounds but nada. A small enema helped but was afraid to take much for fear of the incisions. One week passed and was the most miserable I've ever been. Ducolax and another bottle gave the relief I needed. A sense of well being after a wonderful bowel movement. Will never make fun of constipation again.

A standard 10 oz bottle takes 45 minutes if there has already been a series of enemas, and about 90 minutes if there hasn't. It typically peaks in about 2 hours after that, and is basically done 6 hours after you take it.

My experience has been the same as StephenS -- about 2 hours on an empty stomach. I have found it goes through rather quickly with not much after the first session on the toilet. So for me I am past the effects in under 3 hours. On a full stomach it will take longer to start and the completion will drag out a bit -- but I think I have only taken it once not on an empty stomach. I do not find it a big thrill so most of my experiences have been for medical reasons when I the instructions included an empty stomach.

Hi - you have to experiment a bit with the oral laxatives, including the Mag Citrate. For me, they tend to take hours, sometimes 2 days to work. Some just don't work at all. I have not yet tried any of the "prescription" laxatives like the ones used for colonoscopy preps.

If you experiment before you want a big day of play, then you will have a better idea of the time and intensity expected so you will not be disappointed.

As others have said a lot depends on how recently you have eaten. I have had it go through in a little over an hour on a totally empty stomach or take 3 hours or so if I have eaten more recently. Typically after the first round there is not much left so once the action begins I am finished in a half hour.

Ginger695, If you try citrate of magnesia, 10 oz bottle, quite cold, on an empty stomach, don't plan to take out the trash any time soon! If you want to get it out of you a couple of Dulcolax tablets will quickly propel the liquid once it reaches the bowel. More than two Dulcolax and I would not recommend leaving the bathroom once the first cramp is felt, accidents can be very sudden and messy.

This sounds awesome. Someone explain this to me. Where do you get the stuff, what does the ducilax do and how do you take it. Is this like a total flush out?

Citrate of Magnesia is a saline laxative, holding liquid in the bowel thereby flushing things out.

Dulcolax is a stimulant, (irritant), laxative. It directly stimulates the nerves in the bowel producing evacuation. You need to read the label on Dulcolax, (bisacodyl), then start experimenting. Just remember, when it kicks in there is no waiting, just a rush to go. Taking more than three tablets usually results in a violent movement; loss of control can occur without warning!!

Had a lithotripsy yesterday (Monday), which required an empty bowel to improve stone imaging. 10 oz. of Mag. Citrate at 5:00 p.m. on Sunday produced results in @ 45 minutes and continued to produce some watery diarrhea until bedtime - and again in the a.m.

I resumed a normal diet by noon on Monday. It's now 48 hours since I took it and nada, except for some farts. My regularity is usually like clockwork. I know that I have to "refill the pipeline" but this is annoying and doesn't seem normal.

When I engage in serious enema sessions (3 - 4 - 5 in a day) it occasionally takes two days to resume, but this seems odd. I have plenty of resources available to make things happen, but wondered if anyone else had similar results. Of course, all of the on-line information talks about the beginning of the process and a tiny bit about adverse side effects, but longevity is completely missing.

I took something over the counter for colonoscopy prep and drank it with a couple of liters of water. I'm assuming it was magnesium citrate or some derivative thereof. I was on the potty in 30 minutes and it seemed like it lasted less than an hour. I have heard horror stories about it but I really thought it was pretty easy. The colonoscopy itself was really too bad either after being put mostly under. All in all not a bad experience.

For a full bottle about 6-8 hours

Begins anywhere from 1-12 to 3 hours after you take it. Peaks about 4-5 hours in and starts to lose effect after 5 to 6 hours. Is completely done in 8 hours.

That strange BE that my Mom had when she was 14. The prep instructions recently turned up.

Of course there was the fasting, No solid food the whole day before.

The prep itself started at 3PM with a Fleet enema. Then at 4 PM the Magnesium Citrate, at 7 PM the 30 mg oral bisacodyl. At 4 AM the second Fleet enema and at 6 AM the potassium bitartate suppository

YMMV. In me it didn't START for 8-9 hours and kept up for about 4-5 after that. Not planning on doing it again.

I was very glad I didn't have anywhere I needed to be!

2 enemas can be in and out in under an hour and 15 minutes.

The "how soon/how fast does it work" is in the past, as I related in my post.

The "time to resuming normal movements" is my question. It's now day 4 and nothing yet.

Perhaps no one knows.

Probably depends on how much you eat and drink. I would think 2 days is probably about average but 4 days is definitely going long. I'm sure you'll think of something

If you take lots of distention enemas and are completely cleaned out, you could take a long time -- even a week for your stretched colon to fill and resume normal operation.

EAT HIGH FIBER VEGETABLES

This is why I go at least 8 hours and if I can do it 12 or more without solid food and drink plenty of water before taking any laxative.

Lisa,

You are right: So it will be the best to take a laxative early in the morning, not having breakfasted.

When I had my last colonoscopy, magnesium citrate, was part of the prep. The instructions were to take one 10 oz. bottle at 4 pm two days prior to the procedure . ( I would later take the gallon of PEG in a split dose the evening before the procedure)

When the nurse was going over all the printed instructions with me to make sure I understood everything, she asked me if I had ever taken magnesium citrate before and when i answered no,she told me it was an over the counter laxative and recommended the lemon flavor and then said to just make sure I stayed near a bathroom for the next 4 hours after drinking it.

She was pretty much right on target with those instructions.

As i recall, it didn't "kick in" for about two hours, but I did spend the next two hours in and out of the bathroom. 😁

People are confusing how long the actions of mag citrate last and how long it takes for the colon to re-fill and produce a normal BM.

The mag citrate works for several HOURS. Refilling the colon to produce normal BMs can take up to a WEEK in some people due to their transit speed and diet.

I find that the BM's usually end after about six hours, although they have lasted eight. Sis and I like to do a total cleanout (bare walls) once a quarter. We start by fasting all day Friday then drink 4 ounces of castor oil Friday night, which usually moves us first thing Saturday AM. (We diaper up, just in case things happen as we sleep...not an infrequent occurance.) We follow that BM with 4 Dulcolax suppositories, held until cramping is strong. When we cannot hold ourselves, we release whatever the suppos bring down. We wait about an hour, then give each other two quarts of very strong Ivory soap solution, using our eleven ounce douche bulb. We alternate giving each other a bulbful, so the soapy water has time to work its way up into us between bulbs. We hold as long as we can, and usually surprise ourselves with how dirty the water is. After about thirty minutes, we give each other three quarts with the bulb, again alternating. This release is usually straw colored milky water, with almost no solids. As soon as we are empty, we switch to our four quart bags, and relax on the bed as we take them together. The final soapsuds enemas are as much as we can tolerate. We empty the four quart bags, then refill and take as much as we can hold. I usually manage five, sometimes six; Sis can sometimes empty the second bag. Obviously, we release immediately. We then do two salt and soda rinses, four quarts each. After resting (and perhaps releasing a couple of times) for two hours, (we drink four glasses of water as we rest) We drink a bottle of magnesium citrate as a check of how empty we are. This usually causes clear liquid BM's starting in one hour, and lasting three or four. We end the session by drinking Gatoraide to replenish electrolytes. We eat dinner after 2 hours. Our next BM's are usually five days later. So, our experience is three to four hours after total cleanout, six to eight if normally filled colons.

It depends on the situation … some times acts quick and sometimes takes a while has been my last time I took it it took 6 hrs to work and lasted effects were all day ??

Susie was the only one who understood my question and provided a useful answer.

As it turned out, my question was finally answered on the night of day 5 (Mag. Citrate ingestion + 5 days), although the BM was shy of normal. BTW, Susie, I am the chef at home and focused on foods with ample amounts of dietary fiber for the reason you noted. It still took 4 more days after I resumed a normal diet. My typical transit time is 12 - 18 hours, so that's another reference point.

My pre- and post-procedure did not involve any enemas (although one was eventually offered by a helpful friend! TYVM!!), so my re-establishment was longer than I expected. I was also reminded that because I had anesthesia for the lithotripsy, a side effect could include a sluggish digestive system.

This experience was 100% clinical, rather than kinky, so I was seeking a conventional answer. As is often the case, Suzi came through! Much appreciated and happy to add a coda to the story.

I was also reminded that because I had anesthesia for the lithotripsy, a side effect could include a sluggish digestive system.

You didn't say anesthesia here, and I didn't connect the dots. Hell yes, last time I had general it messed up my colon big time. Don't blame the prep for everything!

I can attest to not going for a while. I usually do 3 to 5 enemas in a series to run clear. The last few are done with a 5 foot colon tube which usually cleans me out completely. My next natural BM is usually 3-5 days later, sometimes longer. It’s kind of nice not having to worry about finding a bathroom to go for a few days. But when they do start back it’s usually 2 to 3 a day for a while.
