Magnesium hydroxide for Constipation "Absolute worst medication ever. I took the recommended dose and have never felt such pain in my abdomen, along with the absolutely worst nausea and diarrhea for the whole day and counting. I can’t express how bad of an experience this was."

Magnesium hydroxide for Constipation "Took at 9 a.m., hoping to move bowels the same day, after days of horrible constipation and bloating. MoM claims it works within 6 hours, but nothing happened. I took another dose at bedtime, still without any movement. The following morning, I have awful diarrhea. It's so bad it gave me an anal fissure, and I've been taking Imodium and putting on lidocaine to ease the pain. Ridiculous to go from one extreme to the other. Yes, I should not have taken a second dose, but thought it would be fine since it did not work at all after 14 hours, and supposedly, you can take this daily. I thought this would just quicken transit time, but no, it stayed in my gut, mushed everything to liquid, and gave me the worst diarrhea ever. Never taking again!"

Magnesium hydroxide for Constipation "First time I took this (60 mL), I drank a full cup of water with it and then went and laid down with my heating pad and Netflix—within one episode of my show, I had to run to the bathroom. Then had watery diarrhea for the next two days. It definitely cleansed me. I took (30 mL) two more times, and nothing happened [without drinking water with it], and now just took 60 mL followed by a full glass of water, and instantly after, I was running upstairs to the bathroom, so while sitting here, I thought I’d write a review! This stuff is gentle and gets the job done without worry!"

Magnesium hydroxide for Constipation "Been having really bad pain in my lower right belly and backed up for 3 days and throwing up. Couldn't keep food down. I was really bloated and constipated and in a lot of pain. Tried the Milk of Magnesia and it worked in an hour, but then I have been up with really bad diarrhea non-stop and cramps. I took the lowest dose."

Magnesium hydroxide for Constipation "Took MOM (Milk of Magnesia) yesterday afternoon around 3:40 pm to be exact. It did not start working until almost 7 hours later, and it’s still working after 12 hours later. Started out as very watery stools, then it hit like crazy. I hope I never have to use this again. Definitely works, that's for sure. Just don’t go far from the bathroom and drink water to keep from being dehydrated."

Magnesium hydroxide for Constipation "I was very constipated for about 5 days, in pain and feeling sick. I went to a very small pharmacy, and MoM was the laxative they had. I took 65 mls at 11 pm, then went to bed. I woke up at 9 am with some stomach gurgling and nausea and nothing else. I woke up again at 11 am with some gas, which I passed, then right after felt an extreme urgency to use the washroom. I had diarrhea that was mostly water, and on my way back downstairs, I felt the same urgency and needed to be back on the toilet NOW. I went back for round 2. It is now 1 pm and I am still having diarrhea, always mostly water and has been explosive a few times. This product definitely does its job but has caused me to have diarrhea several times, and based on the stomach gurgling and gas, I do not expect it to end soon."

Magnesium hydroxide for Constipation "I had a baby, and afterwards, was constipated for 9 days (even with daily stool softeners). On day 9, I got MoM. I did not take the max dose. I was able to have a bowel movement (what I believed to be 9 days' worth) within an hour. My baby is now 12 days old, and I still have constant diarrhea and can't eat without ending up on the toilet. I won't take this again."

Magnesium hydroxide for Constipation "I will never take this again! I had been constipated for about 3 days. It was horrible. I was in so much pain. I decided I needed something to help. I've never taken a laxative before, but I've read that MOM is supposed to be gentle. I took it at about 10 pm. At 11:30 pm, I was in the bathroom with explosive diarrhea! It's been over 24 hours, and I still have diarrhea and feel disgusting. Thank goodness I don't work on the weekends, or I would have to call out! I do not recommend!"

Magnesium hydroxide for Constipation "Traveled to the US to visit my significant other, but hadn't gone to the bathroom for a whole week. My s/o's mother explained that traveling can cause constipation, but I was desperate for a BM nearing 8 days and no BM, and was looking up all sorts of routes to try and take. I bought suppositories and other laxatives to try, but Milk of Magnesia worked in exactly 12 hours, 60ml. Took it before bed, woke up exactly 12 hours later, and I'm still glued to the toilet seat---I'd pick the runs over being constipated any day."

Magnesium hydroxide for Constipation "I’ve been having more than usual constipation lately. There’s a good chance that it’s from my poor diet. At least I now have a bottle of MoM ready. Mostly because, decades ago, my mother, an RN, gave it to me and my three siblings. I hated the taste then, and the “original” sold now is still bad tasting. But I took it anyway and, unfortunately, a little extra, thinking that was needed. If you read of others' experience with taking extra, you know what happens. With me, it worked overnight and then kept on working. Diarrhea is NOT what I wanted. Next time, I’ll be more careful, maybe starting at a low dose. Be sure to read the directions and use the supplied measuring cup. You’ll probably be very happy with MoM."

Magnesium hydroxide for Constipation "I took the max dose of it after breakfast for the first time for chronic constipation. I didn't have a BM after 7 hours and just had horrible heartburn, stomachache, nausea, bloating, and vomiting. It was basically a lot of pain, and I was so sad that I took this in the first place because the pain was worse than not pooping for 2 weeks! I got a BM the next morning, and it was completely watery diarrhea, and it was the worst pain ever. I told my doctor that this is just painful, but he told me I have to take this because I already tried everything, nothing worked, so MOM was the last choice. I already done a test, and it was all normal. Anyway, it was the worst pain ever, and I would NOT recommend this!!!"

Magnesium hydroxide for Constipation "I took Milk of Magnesia at around 10 p.m. after being constipated for about four days. I drank half the bottle. At four o'clock in the morning, I woke up to terrible cramps. I sat in the bathroom for almost thirty minutes until I got a solid stool. Then I spent the next four to five hours dealing with violent diarrhea."

Magnesium hydroxide for Constipation "If you want this medicine to be effective, drink plenty of water after taking it. All magnesium does is draw water into the bowel, so the more you drink, the faster and looser the stool will come. :)"
