For Constipation, Acute "If you are at all sensitive to sugars, beware. What it was supposed to help, just made it 1000x worse. When I actually looked it up, I figured out why I was suffering. Was not a fun night, my poor dog lol"

For Hepatic Encephalopathy "My dr said this would soften stool. Well it does do that. Like liquid water in a matter of hours. Stayed up all night on the pot with constant diarrhea and some seriously explosive gas but I felt a lot better by morning"

For Constipation, Chronic "Haha I am so laughing you guys are funny. So mine is chronic for almost a year, after it started in the 3rd trimester of pregnancy. Its never been an issue my whole life, I'm almost 40. I have tried everything you can think of. It works and then just suddenly stop working. Which most of the stuff give such bad cramps. So I thought to try Lactulose. Well its been day 3 with 15ml morning and 15ml night. I went twice which is so little and feeling its not enough. Earlier I took 40ml and the gas, its just gas "

For Constipation, Acute "This worked after 48 hours. The label said that it could take up to 48 hours, but most of the other reviews said that it worked much faster, so when it didn't work quickly for me, I began to lose hope. Thankfully, it worked, pretty much exactly after 48 hours. I'm in my second trimester, and hadn't done a poo for 4 days, and the last time had been very painful. I'd felt incredibly bloated and uncomfortable, and hunched over when I walked, and couldn't get comfortable to sleep. When I first went again after 48 hours, it wasn't easy, but it wasn't really painful either. I stirred the medicine into large glasses of water to help me drink enough fluids, and also to dilute the excessively sweet taste."

For Constipation, Chronic "This works better for me than Miralax — which worked well but less consistently after taking it for a few years. I am underweight due to the GI issues making it hard to eat (110lbs 5ft 6in man) so I take a small dose, 10mL RIGHT before bed to avoid any gas pain (which isn’t bad, I sleep on my left side to help it pass, gone by AM) and drink 4-8oz of water with it. If I’m not well hydrated I learned I will cramp, but that’s an easy fix. By the AM after coffee I’m good to go. No diarrhea usually, just normal stool w/o pain. No bloating or nausea either. It leaves a coating in the throat so I chase it with juice and then drink water. I’d recommend using a syringe and aiming it past the tongue if the taste bothers you. Initially I was backed up so I took 15mL 2x/ day and now maintain with up to 10mL nightly, occasionally 15mL nightly if I’ve had a lot of carbs or fibrous veggies. I’m now able to eat well and gain weight."

For Constipation, Chronic "The negative effects of this medication make it the worst I have ever experienced in 70 years of living! Abdominal bloating, incredible painful stomach pressure, diarrhea, sweating, pressure on the prostate gland and hardly not relief from constipation. Let the user beware!"

For Constipation, Acute "I was prescribed lactulose for constant bloating and constipation but the taste is disgusting and taste so overly SWEET! ( like drinking syrup ) but apart from that I find that it doesn't works as well at all, unlike the sodium picosulphate it works instantly after 7hrs. This laxative isn't as effective at all apart from it causes excessive WIND and they smell so bad to the point it's too disgusting to bare. Plus I can't tell when it's a fart or a poo neither it's scary to expel it incase I poo myself :/ TMI I know but it's TRUE! I don't think it's as good for constipation but good for wind but it also has not helped with bloating as I still wake up bloated and have it all day and night :("

For Constipation, Chronic "After a colonoscopy, I was prescribed lactulose 10 ml. I have IBS and the Colonoscopist didn’t even ask if I have IBS Within half hour I was in a bad way - diarrhea, feeling sick, then after that, I got spasms, and muscle cramps in my foot. I’m pretty sure that was a side effect of the medication. This lasted through the night until the next day. Most of the symptoms went away except the foot muscle cramps and my whole foot is sore, numb, and tingling. I’m pretty sure it is a severe electrolyte imbalance that can cause serious health problems, such as muscle spasms; twitching; a seizure, or a fit. Yes it’s awful and I’ve been to the doctor and they don’t do anything. Apparently, lactulose shouldn’t have been given to me if I am an IBS sufferer. I just hope this pain goes away Painkillers don’t even help. I will never touch this stuff again."

For Constipation, Acute "This worked well for me and relatively quickly too. I took my first dose at 2pm and by 10pm I was all cleared out and more comfortable than I had been for days, The process was comparatively painless though not without its frustrations; literally hours of sitting on a toilet while a very slow but unstoppable molten flow issued from me! Other than a bit of a crampy and gurgly tummy, I suffered no side effects either - before this, I had tried Laxido and Dulcosoft, both of which made me vomit within an hour of taking and gave me acute abdominal cramps. The taste of lactulose is much more palatable as well - it is very sweet, though could be diluted in juice or water if this bothers you."

Duphalac (lactulose) for Constipation, Chronic "I was struggling to pass bowel motions so decided to seek advice from a pharmacy. They asked what medication I was on. I informed them that I took Gliclacide for diabetes & Allopurinol for gout. They recommended Duphalac. I have following observations and advice. The leaflet recommended a dose of 15 - 45ml. I chose 15ml. within two hours I had a HYPO and bowel motions that lasted over an hour on & off. There was no warning of that possibility. Also I noted that the plastic bottle container cap was not childproof!! I do not recommend this product....AVOID."

For Constipation, Acute "Lactulose does not work at all. I got it in the ER and was told to go home and continue taking it. I finished the whole big bottle days ago and still nothing. Before the lactulose I tried all the over the counter pills, psylium husk, fleet enemas, suppositories, magnesium citrate etc for 2 weeks. It's now approaching 3 weeks and still nothing. At least the mag citrate made me gassy and I felt belly rumblings like there was something trying to happen on but with lactulose no gas, bloating, nothing happening at all."

For Constipation, Chronic "This really helps me, I have an ongoing stomach issue which leaves me constipated at times, with really bad pain, my Husband brought it for me and when I read the label I was really disappointed as it says it takes 8 hours to work. BUT!!! To my absolute satisfaction, it worked in around 1 to 2 hours! It worked really well. But be warned to take it at home where you are readily accessible to a toilet as you will be making a few very urgent trips once it starts working"

For Constipation, Acute "After a week on codeine I hadn’t gone to the toilet properly, tried this before contacting my gp, took the max dose and within 2 hours it had worked and cleared me out, only downside is I can’t trust a fart!!! It said it would take up to 48hrs to work but didn’t expect it to work as quick, feel much better and less bloated"

For Constipation, Chronic "I’m on 30ml, 3x daily. I’ve had chronic constipation since I was a child. Water, fiber, exercise etc doesn’t help. I took lactulose for 4 days and was about to give up and take a stimulant laxative. I thank whatever higher power that’s up there that I waited another 20 minutes because all hell broke loose. I was in the bathroom for 42 straight minutes with a constant bowel movement. Honestly debated on calling 911 a time or two or praying I could get up long enough to get water. Is it a pleasant experience? No. Is it better than hemorrhoids, anal fissures and being completely unable to have a BM? Yup. 100%. Also pro tip, mix it with about a 1/2 cup to a cup (measuring cup) of apple juice. Completely masks the taste."

For Constipation, Acute "Take 45ml in one go, usually use this for one major blowout as opposed to the 15ml twice a day slow burner. Require constant toilet access for about 4 hours after. Toilet is pebble-dashed after, so being alone in the house while this is going on is best. Hate the consistency ."

For Constipation, Chronic "Suddenly over Christmas I just couldn’t go so I drank loads of water and waited a few days but still nothing. My GF went to the pharmacy and brought back a huge bottle of lactulose. I took 15ml cautiously and then another 15ml 20 minutes later, nothing much happened apart from gas until 6pm when I got cramps but that was from more gas. After 6pm I took a further 20ml and still had painful wind. I managed to pass a few tiny nuggets and then had to sleep on my side so I could pass wind all night. The next day I still had similar pains. I drank a glass or two of water and had a banana for breakfast and decided to have another 30ml in one go this time. I laid in bed sipping water and all of a sudden felt cold and feverish, cold sweat ran down my face as I felt sick and had to run to the bathroom and vomit my guts up. My body didn’t seem to like the 30ml I’d had. 30 minutes later the biggest stinkiest log was ejected from my soul, finally saved at last."

"Like 'weeing' out of your bottom?? Take Lactulose... about 60ml, then retire to a safe distance. Oh... you can't!! This is lethal stuff. Works great if you are 'blocked up'. Tremendous flatulence, in both directions. Turns your 'poo' to liquid, which is an advantage if, like me, you have an anal fissure and any straining causes painful bleeding. USE WITH CAUTION"

For Constipation, Acute "I have been taking Duphalac for past 2 year and was while satisfied with its results. But sincere past 4 Months have been taking problem of Excessive Water Retention & Bloating in Abdomen. Water Retention was such that my Stomach used to get swollen and hence had loss of appetite. Because of Inflated Abdomen used to feel chest pain along with dry Coughing. It was really a miserable feeling as had lost 5kgs weight because of not having proper meals. Finally had to stop Duphalac & within a 3-4 days time water Retention, Bloating etc had stopped. It's my advise to people facing similar problem to stop Duphalac Immediately & switch to some other Laxative after consulting the Doctor."

For Constipation, Chronic "After trying several other medications that didn’t work, my doctor prescribed Lactulose at 30ml twice a day, I decided to take 15ml to be safe. Well, I did have a bowel movement but with the worst stomach cramps and bloating. The cramps are unbearable. I only took this medication once and it’s horrible. I personally will never take it again."

For Constipation, Acute "If you’re really chronic and you need to go like NOW, then take 45ML in one go. Make sure you are near a bathroom because it definitely is very on and off for a while. That’s the dose I take when I realize it’s been a while since I went. At that dose it works within 2 hours for me. Effects last about 2 hours also. Is it pretty or pleasant? No, but it’s effective and you feel so much better: it’s also inexpensive which is great."

Enulose (lactulose) for Constipation, Chronic "Within an hour of taking a dose I experience severe nausea and sometimes throw up but when it starts working I feel somewhat better. I still feel constipated some but not as bad as I did. The taste keeps me from taking it twice a day as prescribed or it would probably work better."

For Constipation, Acute "My constipation I can manage with my diet when I’m at home and have a regular routine, but when my routine is out of synch on holiday then it becomes a real issue. when I come back from holiday I will take 50ML in one go. It tastes vile, goosebumps as it’s going down. Maybe the thought of what’s ahead makes it taste worse than it actually is. After that , in about maybe 2 hours I’ll have a movement. After that, I usually have chronic and very smelly gas. As a result I never do this when there’s anyone in the house. Literally I do this at 9am when my husband is gone to work. When he gets back by 6 the gas has usually subsided and I can close all the windows again!! Between gas there are trips to the bathroom, which become less and less solid until finally it’s just all brown water. My advice is, this is excellent for a one off where you have a day where you don’t need to be at work or anywhere else to be."
