Was advised by medical provider to use 1 3-mg tablet of Melatonin. By morning, woke up with anxiety and nausea. Stopped taking it after the one dosage. 24 hours later, bout of diarrhea.
I'm positive it was from the melatonin. Or was was it the pill because it had Magnesium Sterate, which is a natural laxative. What? I'm glad I have Google but so much research. I checked the label of the new Tums "smoothies" I have taken and it too has Magesium Sterate in it as well as Sorbitol (never do I take an sweetner with an -nol ending). Regular chalky Tums does not have these additives. I'll take chalky over anything going in and OUT of me way too smoothly!

So, I'm not attempting Melatonin again! But is it Melatonin or the additives in the pill? As my own advocate, the research continues......By the way....I read that MIT says that any does over 1 mg is too much. So why do they sell doses at 3 mg, 5 mg, 10 mg...etc. They state .3 to 1 mg is regular dose. I ordered 1mg tabs from Walgreens on-line but won't be using it. I'm sure it was the Melatonin but the additives may not help.

My doctor put me on Melatonin for Insomnia and almost immediately I got horrible explosive diarrhea, going over 7 or 8 times a day. I had no idea what was causing it and only briefly wondered if was the Melatonin. I went to the dr and he didn't think it was Melatonin. But after eliminating everything I could think of, I decided to quit the Melatonin and no more diarrhea.

Doctors should be notified about this!

I too have been experiencing diarrhea for three weeks. I made an appointment with my GI doctor, thinking something was really wrong. After finding this forum, I'll stop taking melatonin and cancel the appointment.

Thank you all for posting your stories. Almost three months after starting to take melatonin almost nightly as a sleep aid, I began a bout of horrible diarrhea that only ended last week after stopping the melatonin two weeks earlier. I never connected the melatonin with my problem so I never mentioned it to my doctor who did stool samples, blood tests, etc., which were all negative. Finally, in searching my mind, I told her about the melatonin and she told me to stop taking it. That's when I found this forum. Since then I learned that it is not be be used as a regular sleep aid, especially long term.

Again, thank you all for posting. Your stories helped confirm my problem.

I did not read this whole thread, but I have started taking melatonin from a company called Patch MD. all their supplements are in patch form so they bypass your stomach. I am trying a few of their products trying to cut back on all the pill supplements I take.

hi there, i could not help to share my horrible experience with melatonin. I started taking 3 mg after my mother tragically passed away and slowly increased the dosage to 25 mg as the effects on my sleep was as i used it nightly was decreasing. just so you know all it has been a week since i took my very last pill and im not 100% myself yet but getting better everyday. my experience was really bad until i found this group and confirmed my suspicion with my several times a day diarrhea, stomach cramping and bloating. i though the worse until i realised that melatonin was causing this. i also was feeling tired, moody and put 5 pounds. im a extremely healthy person i put an average of 40 miles on intervals workouts a week. i had not mut energy. im 5'5, 105 pounds quite consistent with my weight, loosing weight more than gaining due to extreme hikes. i was very surprised with my weight gain due to the hormonal effects of melatonin. but the very worse was the horrible uncontrollable burst of diarrhea. yes melatonin helped me sleep but the side effects are absolutely not worth it. im slowly getting back to norm (diarrhea only in the morning, instead of several times a day).
im taking powerful chamomile tea (pure from flowers) and im sticking with it. neve melatonin again

I'm so glad I found this forum as I honestly thought I was losing my mind. I've been taking Melatonin (10mg!!!) to help me sleep (Ive always been a really poor sleeper) since the end of September 2017. For the first 6 weeks, all was good, getting a great night sleep. And then for no reason at all on 20th November I woke with the worst diarrhea imaginable. I thought it was food poisoning but I didn't feel sick. This has been going on until now, 9 weeks later. I've been to numerous doctors, had acupuncture and reflexology and I went for energy healing last Thursday. She told me she felt my body was saturated with melatonin, despite the fact I hadn't told her I was using it. Because all the doctors results, blood tests, coeliac testing, stool tests etc came back negative everyone was suggesting I was very stressed. I was very down, anxious, exhausted, low energy, paranoid, the total opposite to how I normally am. Crying and feeling I was going insane. I stopped taking the melatonin 4 days ago and already the fog has lifted from my brain, I'm back to myself emotionally and feel life is good. The diarrhea has not yet stopped but it's definitely reduced. I was going 10-12 times a day, explosive bursts of uncontrollable diarrhea, some cramping but no weight loss. I couldn't believe after 9 weeks of diarrhea there was no weight loss! Hopefully my body will get back to normal very soon, I'm booked for a colonoscopy next week and I'll go ahead with it, but my advice is to steer clear of melatonin. Thank you for all the posts, they've confirmed what my energy healer suspected.

Hello!
I am so thankful to have found this forum. I have been researching for over a month with regard to my problem. After having all blood, urine, and stool sample tests coming back negative, I felt very frustrated! I have requested an ultrasound before seeing a gastroenterologist. It has been 9 years since my first colonoscopy. I have not been diagnosed with IBS, and I may not have a serious intestinal disorder.
But I believe I have discovered the cause of my diarrhea!
I began taking Melatonin (5 mg) as a sleep aid in mid-October. Explosive diarrhea began on December 7th. I keep a daily log of food intake, number of trips to the bathroom, Bristol stool chart rating, etc.
Last night I stopped taking Melatonin and I sincerely hope that this horrible onslaught will end soon!
Like most, I feel like I was going crazy, crippled in daily activities, having to map my daily route with knowing where the restrooms were located in the stores, etc. I even have had to slip out of church service several weeks in a row because of this.
I agree with others: the side effects of Melatonin and safe dosage amounts should be CLEARLY labelled. I do believe this side effect is not as common for most people, but those of us who have extreme sensitivity are the most impacted.
I was using the Walmart brand: Equate. The label does indicate short time use only, with a peel back label I just noticed as I'm writing (pale grey lettering/not easy to read) that lists non-medicinal ingredients and warnings, etc. Diarrhea is not listed, only "Mild gastrointestinal symptoms (nausea, vomiting, or cramping), none of which I experienced, as well as "rare allergic reactions have been known to occur, in which case discontinue use."

So, I am really hopeful that I have discovered the cause of my chronic diarrhea.

Also a question: Has anyone else experienced any hair loss? I am upset with the amount of hair clumps/strands that are in my comb. Could it be due to malabsorption of nutrients due to the diarrhea?

I came across this thread last week, and I to wanted to let others know what was happening to me. I started taking a chewable mint melatonin tablet about 2 months ago. about 1 month ago I started have extreme diarrhea. I waited about one week and then went to instacare because I couldn't get in to my regular doctor. They did stool cultures including giardia and found nothing. I waited another 2 weeks of this horrible cramping, explosive diarrhea 10-15 times a day and finally made an appointment with a gasterenterologist. He ordered blood work, and more stool cultures and found nothing. The following week I had an upper GI and lower GI done at the hospital. They took biopsies, but the conclusion was colitis. My doctor did start me on 10 days of Flagyl. After finishing that I was still having problems. They ordered a very expensive round of 3 months of Entocort that was stepped down from 3 pills a day, then 2, then 1.

I have ordered the pills from a Canadian drug company due to my cost in US is almost $2500 for the 3 months of medicine.

I did stumble on this forum and ask my doctor if Melatonin could have started this, but his opinion was that not likely. I did however stop the Melatonin and after the first round of antibiotics of Flagyl I have improved. I am not perfect yet, and when my Entocort gets here I will likely start that. In Canada the Entocort was $131 for the 3 months. I just want others to know, I still think the Melatonin is what started my issues. I am 63 yrs young and a female. I have read where Melatonin can be more sensitive with women over the age of 60 and taking Vitamin D. Which I am. Hope this helps someone else.

My husband is a retired physician. Some years ago, he began to take a small dose of a prescription sleep aid and that has worked well over the years. Browsing in the drug store recently, he walked past the "natural supplement" shelf and spied melatonin advertised as a non prescription sleep aid, so he decided to try it and purchased a bottle of 10 mg (!) pills.

That evening he started by taking one pill at bedtime, and yes, it helped him sleep, and he was very happy as a result. So, the next night he took another pill and did so again for about six days in all.

about four days after the first pill, he began to experience watery diarrhea two or three times a day, and it was the same for the next few nights, and so I began to investigate the cause. I came upon this site, and read these posts about similar cases.

So, he stopped taking the melatonin immediately.

The diarrhea has continued for at least three weeks, with no help from imodium or peptobismol. Finally he got a prescription of Lomotil, and that has helped. The diarrhea attacks are lessening, finally. And, he and I are convinced it was caused by the melatonin, especially the 10 mg dosage. The real concern is that the problem has lasted for so long.

It is hard to believe that there are not more warnings out there about melatonin in particular.

Hello with an update after two months...

My diarrhea cleared up within a week of stopping Melatonin. I did go ahead with the c. difficile test which came back negative. I cancelled the appointment for a colonoscopy (due next year, every 10 years here in Ontario).
I informed my family doctor through her nurse....sounded skeptical. I am seeing my doc in a couple of weeks and I am printing out this thread.
I wish the potential dangers of overdosing on Melatonin were more in the forefront of information.
Dr. Oz?????

@ jha.....My diarrhea lasted from December 7th through January 24th...so hang in there; I'm sure it will lessen soon
@ Madgreen: I hope you haven't spent a fortune on meds. I personally think that time is needed. How are you now?

I am 67 and female.
Also, I experienced some hair loss; I believe it to be from malabsorption of nutrients due to the diarrhea.

P.S. I also began taking Vitamin C in flavoured chewable form in late January. After a couple of weeks I experienced diarrhea again. I stopped the Vitamin C. I'm back to normal.

Hi all,

After reading this thread I felt relieved as I was also going crazy myself. I stopped taking Melatonin about 2 weeks ago and I'm still having diarrhea several times a day that usually stops around noon or 1. Has anyone elses side effects lasted this long? All my tests are also coming back negative and I'm at a loss of what to do. Any recommendations of what to do would be great.

Thanks all.

I am so thankful for reading this post! I have been in the bathroom for days!!!! Like 10 times a day! Been to the doctors, had all the test done, on a probiotic, ultrasound of my bladder and everything was negative. As I’m driving home today from work I said to myself what have I been taking that’s different... sure as hell I realized it was Melatonin 5mg. Bam! That was it! I immediately came home googled it and found this site. Thank you sweet baby Jesus! You can bet your bipy that I shot that bottle right in the garbage. My question now is how long before the 10 times a Day bathroom issue goes away??? Please someone tell me 😉

How long does it take for Melatonin to leave your system?

I have been dealing with the same thing for 2 weeks now, went to the doc yesterday and he wanted to run a bunch of test. I, like everyone here had tried everything under the sun to fix and figure out what was going on since nothing seemed to help. I woke up this morning to do more research and stumbled on this site and I am so happy!! Now I know why I call myself Dr Google since most Dr's do not look for the simple things that could be causing things. Now it's time for getting back to normal!!

I read in this forum that it will take anywhere from 2-7 weeks to get better.

I also developed watery diarrhea following taking 1 mg of melatonin at bed time for about 5 to 6 weeks. The diarrhea was persistent and worse in the morning. I had a negative stool culture for giardia. After reading this blog, I stopped the melatonin. The diarrhea resolved within a week. Fortunately, I read this blog before undergoing colonoscopy and biopsy, as well as treatment for irritable bowel syndrome.
