For Constipation, Chronic "I have had chronic constipation most of my life and never thought too much about it, I just accepted it. I've been on pain meds for close to 6 years, and they are definitely making it worse since I'm having pain, which concerned me. So, I had a CT scan to make sure the pain wasn't coming from something serious. The doctor felt the constipation was the cause. I'm on day 1 of this stuff, and I was prescribed 30 ml 3 times a day. I waited for a day I could be home in case it got bad. I had my first bowel movement about 1 hour after the dose and 3 total since the 1st dose (took 3 hours ago). I think I'm going to stick with 1 a day for now, and if it slows down, then I will add the second dose and work my way up if necessary. It tastes like honey but has a thinner consistency."

For Constipation, Chronic "I take 6 Percocet daily for back pain. 30ml of lactulose generally takes effect in 4 to 6 hours. At times it can produce diarrhea if I take more. At times I can skip a day as I am able to have bowel motion naturally. It doesn't adversely impact my blood sugar levels."

For Constipation, Chronic "I would go up to one month without having bowel movements. I'm very afraid of using medicine because I take medication for epilepsy, and I do not want any interactions causing the anticonvulsants to be less effective. My doctor gave me lactulose and told me to drink water with it. He said not to be worried about it interfering with my medicine because what the lactulose does is pull water into the stool to make it soft. I still don't take it with my daily medication. I wait at least 3 hours after or 4 hours prior to taking my daily medication. The only thing I do not like is it is very sweet. Check to see if it is okay to take if you are diabetic. I assume it has sugar in it because of the sweetness."

For Constipation, Chronic "I had to see the doctor eventually due to having an anal fissure, a very painful thing to have. I was finding it hard to get any sleep without pain. My doctor suggested taking a lactulose brand called Actilax. I haven't ever taken laxatives. My first dose was after I purchased it at lunchtime and then in the evening. The next day at lunchtime, I had a soft bowel motion twice. Two days later, I took it once a day, no more pain going or blood. I suggest not diluting, yes, it is a thick syrup with an odd taste! But drink lots of water during the day. Side effects: wind! Didn't come with the special dosage cup. Lower the dosage on the third day. I'm so surprised I have no more bleeding, which I had for weeks."

For Hepatic Encephalopathy "Very effective! Usually starts to work for me within two hours and continues to work for hours. Stay close to a bathroom. It decreased blood ammonia level and cleared up the cloudy head in just a couple of days. Stress staying close to a bathroom!"

For Constipation, Acute "I am pleased with the results of this medicine, and the best part is that it has natural ingredients. I don't take a lot of medicines, but this is one that I trust, and I feel it won't do harm to my body, but help it. I always make sure I drink a lot of water with any medicine I take."

For Constipation, Chronic "I have early menopause-related constipation. For the last 5 years, moderate constipation. I've used lots of things - with success but also with fear of dependence. People have recommended lactulose as a non-dependent choice. I take 30 mL at night. It gives me a lot of wind. It does work, but it is an accumulative effect that takes about 4 days of regularly dosing to start working and produce a bowel movement... Not sure why so many others are lucky enough to get success the same day???"

For Constipation, Chronic "Since I began taking lactulose, I have seen a marked improvement with chronic constipation. Before beginning with this med, I would sometimes not have a BM for 10 days. Since starting this medication, I have been having 4-5 BMs a week, which should increase even more as my MD increases my dosage at my next appt. Besides the relief I have experienced, I also enjoy the pleasant taste, as previous meds were horrible tasting. I would recommend this medicine as a very good treatment for chronic constipation."

Lactulose for Constipation, Acute "The worst medication I have ever taken. Not only does it not work, it makes everything 10x worse. Painful gas and flatulence at an unprecedented level. Took it to deal with constipation post-surgery, and it made the surgery pain so much worse. Useless!"

For Constipation, Chronic "This has literally changed my life for the better. I have been told since I was 21 that I have IBS. I had IBS A (alternating between D & C). At 46, at my wit's end, I tried lactulose as my bowels didn’t know what they wanted! Most nights, I take 1 full soup spoon before dinner with a large glass of water, within two hours, along with huge amounts of wind, I am on the loo. If I get a little sluggish, I up the dose by 1/2 a spoon or even 1 spoon. Worst case scenario, there is more wind or a quicker dash to the loo or even a dose of D... but never any cramping anymore! I then reduce the dose. It is all about the dose. For anyone struggling, you may need a bigger dose to get it going, then a smaller dose to maintain. I have my life back! Finally, at 46, I am free again!"

For Constipation, Chronic "Well, after 11 months and with scans and doctors, the local chemist recommended this today, and 4 hours later, total clean out. I am so impressed, 10 hours later, it is the best. I have had this problem for 11 months, and I cannot understand why any of the doctors and specialists didn't pick up I just needed to go to the toilet properly and regularly. Try it for a while, but at first time, 10/10."

For Constipation, Acute "So I am a new nurse but have overcome a lot of health problems. Due to wearing a girdle to support my large hernia and lack of water from rushing around the ER, I became suddenly constipated. For three weeks it was wait until my days off and stay in the bathroom in agony. So I went to my doctor, and they gave me this, it was actually sweet! I took a shower, and by the time I was done, so was my problem! I am amazed, and my IBS even seems to be calming down!"

For Constipation, Acute "So... I have been having trouble passing a bowel motion as currently there is a tear. Anyway, I would hurt when I was trying. So I was quite scared to go to the toilet knowing it was going to hurt. My partner has lactulose, which was for himself previously. So I took the recommended dose. A couple of hours passed, and I was delayed by the fact I needed to go to the loo. So I took another dose. OMG... DO NOT TAKE ANOTHER DOSE 2 HOURS AFTER. I was farting, burping, farting, left, right, and center, stinking the place out. I was ready to go to bed when the trapped wind came along. So I ran to the toilet, and that’s when all hell broke loose. OMG. I’ve never been that bad ever. It’s really gross, and I wouldn’t want anyone to go through that. My partner came through to see if I was okay, and funny enough, he’s making a joke out of it, but trust me, DO NOT TAKE MORE IN 2 HOURS, your toilet will hate you. I’m okay now, it does its job if that’s what you were looking for."

For Constipation, Chronic "I've literally tried everything for my constipation. A high-fiber diet made it worse, and I was relying on more dangerous laxatives. Lactulose didn't work for me to begin with until my gynecologist told me to increase my dosage, so I take 40 ml twice a day. I now have a bowel movement every day, whereas in the past, I'd go once a week and still be blocked up. It is a lifesaver. The only negative thing about it is the water retention. It has made my stomach so bloated and made me gain about 5 lbs in water weight, but these side effects are tolerable. I'll just keep to loose-fitted tops for the mean time :)"

For Hepatic Encephalopathy "My wife started getting dehydrated at the beginning of this year, and I repeatedly took her to urgent care for rehydration. Her symptoms would go away but come back three weeks later. During a hospital stay in Aug 2017, my wife was given Reglan in her IV to treat nausea with disastrous results. She immediately forgot where she was, who I was, or that she was in the hospital. This lasted 24 hours, but the incident left her with profound hallucinations for about three weeks. She got dehydrated again, got over-medicated on hyperidol, and then got a blood test that pinged on ammonia. It all fits. The Reglan damaged my wife’s already overworked liver, and she’s been dying of ammonia poisoning ever since. Lactulose may be a Godsend. We hope so."

For Constipation, Chronic "Having had a hysterectomy, was told I was not to strain when needing to poo. Having had a dose after trying other methods, i.e., drinking more water, extra fiber, and other laxatives, finally relief. When at home, I purchased Lactulose over the chemist counter. WOW, one dose a day, no more constipation, very content with this product. I can’t recommend it more highly."

For Constipation, Acute "So I've been constipated for about 4 days, and I've tried everything. I went from eating more fiber to trying to force it out. I told my parents, my mom, who was clueless on what to do, told my dad, and he gave me lactulose. It took about 4 hours to kick in, and it did not hurt at all to poop, and it was just so amazing getting it all out. My stomach did feel uncomfortable before I pooped, but it really does go away. I stayed near the bathroom for about an hour, but I guess it depends."

For Constipation, Chronic "I’m 17 weeks pregnant and have been struggling even before I found out I was pregnant to empty my bowels. Before I fell pregnant, it was normal for me to poo once a week. I can’t even remember when I had my last bowel movement, it was over a week ago and very small. I rushed to the pharmacy today to get something as my stomach feels bloated and painful. I took 45 mls, and within half an hour, I started feeling sick, and an hour after that, I started cramping. Three hours later, I’m shooting to the toilet before I end up having an accident. What started off as a normal stool turned into explosive diarrhea. But I guess with 7+ days of waste in me, it was going to be a bit of a mess. So glad I took this, however, I wouldn't recommend taking it before work/going out, etc., as it can be unpredictable as to when it will take effect. Also, the wind is a bit embarrassing, so better to be in the comfort of your own home. I would recommend."

For Constipation, Chronic "I have inflammatory bowel syndrome that sometimes causes me not to have bowel movements for weeks. My primary care doctor prescribed this to me for my IBS. I take 15 ml of this twice a day. It says it's supposed to take 48 hours to work, but it certainly doesn't take that long for me. It tastes horrible on its own, but I mix it in with pink lemonade, and I can't taste a thing."

For Constipation, Chronic "My doctor put me on Constulose after years of me using over-the-counter medicine for chronic constipation. I had 3 ERCPs, a tube down my nose to drain fluid trapped in my stomach. Lots of hospital stays and the pain from not having a bowel movement is torture! I would go two weeks without having a bowel movement. I've tried senna, stool softeners, milk of magnesia, and more. Finally, my doctor wrote for Constulose 15 milliliters and warned me to only take it for emergencies. I go to the bathroom every 3 days or less now. Best medicine so far!"

Lactulose for Constipation, Chronic "I've been having constipation problems for a while now. I tried Linzess, and it worked just a few times, like 2 or 3, so I went back to the doctor and got Generlac. I took it on a Friday at 4 PM, and the next morning it worked. I'm so relieved. So I'm going to continue taking it every day, and I'm hoping it keeps working."

For Constipation, Acute "I was prescribed this only a few days ago because I generally only pass a bowel motion about once a week. My dosage is 20 mls per day, and I initially didn't think it was working, but it has most definitely kicked in now! I've had heaps of flatulence since first taking it, and now, 2 hrs after my 3rd dose, I feel about 5 kilos lighter. I'm so glad that I am not at work because the smell of this first visit to the bathroom is absolutely revolting... (sorry for over-sharing). It tastes sickly sweet, but I'm getting used to it. I think this product will actually change my life for the better. P.S. I'm in New Zealand, where a lot of medication is funded by the government."
