For Irritable Bowel Syndrome "This medication is a lifesaver. I was to the point that I couldn’t eat without terrible stomach cramping and running to the bathroom over and over again. I get very mild cramping now, if any, after starting this. I finally have relief, and I hope it continues to help. It has only been day 3, but the first day I took it, I immediately noticed a difference. I am forever thankful for this medication as I was getting depressed, and it was making it hard to live and do my daily job. My side effects are next to none. I have been keeping up with drinking water, as recommended. If you’re having stomach issues, please give this a go."

For Irritable Bowel Syndrome "Severe IBS-D most of my life, flare-ups have gotten worse as I’ve gotten older to the point where the pain is so bad I black out. Turned blue the last time, fun! So I got prescribed this last month. Light episodes - basically everything passes with a whisper of discomfort. Mid-range - mild cramping but everything is still tolerable & basically a boring bout of diarrhea (totally new to me). Had a severe flare an hour or two ago, immediately took one, sublingual 0.125 mg. It helped ease the pain, but didn’t stop it. Got sick, came back & took another since it seemed to be kind of painful still. This current episode has by far been the worst, about the level of intensity a light flare would be normally. A bit painful, but not doubled over just trying to stay conscious. Side effect of taking two pills this time vs. one - green poo. Be sure to stay hydrated, this will dry you out. Overall though, it’s changed my life for the better & I’m grateful."

For Irritable Bowel Syndrome "I have been really sick since September of 2019. I recently went to my regular doctor, and he prescribed this medicine for what he thought might be IBS. My dose was 0.125 mg every four hours, I take it every four hours, which means 6 a day. It is the ONLY medicine that has helped me at all. No real side effects. If I miss the 4-hour time, my stomach and intestines start cramping."

Hyoscyamine for Crohn's Disease "I have been using Levsin SL for many years for Crohn's (severe spasms). It is very effective. Two years ago, I started having severe spasms and leg cramps due to some unknown disease that is affecting my legs. I have constant pain in my leg muscles and long bones. I also have severe leg spasms/cramps at night. I discovered one night when having both colon and leg spasms that the Levsin SL stopped the leg muscle spasms. I discussed with my doctor, and I started using it at night to treat my leg spasms. The spasms are quite severe, with a pain level of up to 9 out of 10. Levsin is the only medication that I have found to be effective. The half-life for me is around 2-2.5 hours."

For Irritable Bowel Syndrome "I originally was prescribed this for a 'nervous stomach' due to diarrhea from severe anxiety. It works to control my bowels and stop the cramps. I have been on and off the meds for about 10 years, using it to help with flares - it is now known I have IBS. If I take it more than 3 days - 3 times a day as prescribed, I have severe constipation. I use it as needed, taking a single dose every day, and more if I have a flare, stopping for a few days only if I have harder stools."
