For Constipation, Chronic "Has anyone gained weight using lactulose? I’ve been taking it daily for the past almost two years. It works well for me, but the weight part is annoying. 20 pounds, ugh. I don’t know how to get the weight off. I don’t eat a lot. I drink liters and liters of water. I’m frustrated. Please, someone tell me how to lose the weight."

For Constipation, Acute "I had been in hospitals, and I was able to go, but never much. Imaging showed a moderate amount of stool in me. The doctor ordered lactulose. The nurse said it would just make it easier for me to go. It was in a cup that looked like an oversized coffee creamer. I took it right before I went to OT. Less than an hour after, I started cramping. Before I could finish saying I needed to get to a bathroom, I was going. They took me to my room, and I got on the bedside commode. I wasn't able to get off of it for 1.5 hours. I always thought magnesium citrate was awful stuff. This was way more harsh for me. It was effective, but I was not expecting that much of an effect or for it to hit so soon. I would be afraid to take it again."

"Earlier this evening, had 'severe cramps and bloating but no output into my colostomy bag.' I think it could be related to a Metro Egg Sandwich that I had earlier. Tried Divol Plus and 2 Extra Strength Tylenol and heating pad...nothing helped. Called Shoppers in Toronto, they suggested I take 1/2 capful of lactulose. It did the trick within 15 minutes, cleared me right out. Cramps dropped 80%. Came within seconds of calling 911, but I didn't, and I made it through. Remember, too much can cause serious diarrhea in the colostomy bag, so limit lactulose if you can. Take every 3 to 4 days. Not too much."

For Constipation, Chronic "I developed chronic constipation out of nowhere and am a vegetarian, had tests run, colonoscopy, etc., no answers but was suffering daily, every day. Tried dietary changes, bowel training, Movicol, Metamucil, more water, you name it. Became extremely debilitating and distressing. After 8 months of this nightmare, I tried Lactulose (Actilax), and whilst it took a week to really work, now I’m having a normal BM same time daily. I’m currently taking 20 ml twice daily, you may need to see what dose works for you. I know medicine isn’t always a long-term solution, but when you are suffering, it’s worth a shot until you can find another solution. I will keep taking it daily along with a healthy diet, etc., until I can see another specialist. Beware, initially it can cause bloating and discomfort, so start off slowly and drink plenty of water and build up the dose rather than start big."

For Constipation, Chronic "Lactulose 30ml twice a day with lots of water, doesn't seem to work on its own for me. I still need Senokot every three days to get things out, but I think the lactulose at least makes it soft so my hemorrhoids can heal. At this dose, a bottle only lasts 10 days, so I'm hoping I can reduce the dose gradually."

For Constipation, Acute "FLATULENCE! So chronic you’d almost be proud of it. Don’t have visitors over or even use this on a day when you have an empty house. I use it when I maybe drift away from my usual diet and need help, so maybe once or twice a month I take 60 ml in one go. Your poo basically ends up as liquid by the end of the experience. I used to use it every day for a while, but found I was both bloated and flatulent."

For Hepatic Encephalopathy "I take lactulose 3 times a day. Since taking the higher dose, I no longer have any hand tremors and have not had another episode of going to sleep and not waking up for 36 hours. I still have periodic leg swelling if I am really active."

For Constipation, Acute "If you’re really chronic and you need to go like NOW, then take 45 mL 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."

For Constipation, Acute "I have been taking Duphalac for the past 2 years and was quite satisfied with its results. But for the past 4 months, I have been having the problem of excessive water retention and bloating in my abdomen. Water retention was such that my stomach used to get swollen, and hence I had a loss of appetite. Because of my inflated abdomen, I used to feel chest pain along with dry coughing. It was really a miserable feeling as I had lost 5 kg in weight because of not having proper meals. Finally, I had to stop Duphalac, and within 3-4 days, the water retention, bloating, etc., had stopped. It's my advice to people facing a similar problem to stop Duphalac immediately and switch to some other laxative after consulting the doctor."

For Constipation, Chronic "I've had issues with constipation on and off my entire life, may be the cause of my decades of migraines, actually. Once went an entire MONTH without going, can you even imagine that?! Got a high colonic (colon cleanse), and that flushed it all out! This time a doctor prescribed this lactulose stuff for me, thought I'd give it a try. Suggested 30 ml a day, three days later, NOTHING but gas! Today, the fourth day, I decided to up the dose! So I took TWO 30 ml doses, five hours apart, and BOOM! Had one BM, and I KNOW there's lots more still in there, very bad gas too. I am feeling a little crampy, so probably tomorrow I will continue a higher dose and will go again. Eventually, I will lower the dose back down and even see if I can quit altogether as laxatives become a crutch that you can't function without eventually. I don't take any other drugs, no pain meds, and I eat healthy and am healthy in every other aspect but the migraines and constipation, would LOVE to get rid of those!"

For Constipation, Chronic "I have tried this stuff twice over the last 5 years and still doesn't work. I've had 25 ml twice this time, and it does nothing, which is annoying because when I sent the person to get laxatives in the first place, I told them not to buy this, but the guy behind the counter said it was the best. But twice in the last 5 years, I bought this, and it doesn't work. First time I was 18 years old, now I'm 23."

For Constipation, Chronic "I was prescribed Lactulose for constipation that had troubled me for over three years. Had tried other medications. I took Lactulose for two months every day as prescribed, and now have been with no medication at all for over a month. I had no adverse effects while taking it and would return to it if I need."

For Constipation, Chronic "I have been constipated badly, many visits to ER, urgent care, and many CT scans, X-ray, and always dry stools stuck in the intestines. One doctor prescribed lactulose. At first, it caused me bloating. I called the pharmacist and recommended 15 ml and Gas X together. Now I have my normal BM."

For Constipation, Chronic "Brand: XactDose. Manufacturer: VistaPharm. Dose: 20g/30mL. Great results with this medication. I was using Miralax for a few days (4 or so) but didn't get any results. I then took XactDose after going to a doctor. First day taking it, I felt really gassy and bloated within 3-4 hours. My second day I experienced the same things, only this time I actually expelled a good amount of stool. It felt like a decent burden was done away with, and I felt lighter. It's my go-to whenever I get really constipated, it works very well. Didn't get the same results with generic lactulose (10g/15mL) that I got after I ran out of XactDose. I even tried a double dose of it. Maybe I should've tried one more day with the doubled dose? Oh, and it seems like Sam's Club pharmacy is the only place that is able to get this for you now. Many pharmacies don't have it. Call around and ask for lactulose made by the manufacturer VistaPharm and save yourself some gas."

Lactulose for Constipation, Acute "I used this Duphalac syrup, but I can say that it's the worst medicine I have seen ever in my life and has not even a single percent of laxative effect. In fact, it had the opposite effect, it will even increase the hardness of stool. If I had an option to rate this medicine, I would have rated it negatively. Such a waste of a company and product. I would request to don’t buy this medicine at any chance. Rating: -10, the worst."

For Constipation, Chronic "65-year-old male. Have had chronic constipation for 15 years from pain meds for a bad back, sheet metal worker. Since retiring, the condition got worse. Tried everything on the planet. On a 25 mcg fentanyl patch every 3 days AND 5 mg oxy for pain flare-ups. What I have found that works for me is in the morning, I take 450 mg Relistor with coffee, get 25-40% out. Then take 1 290 mg Linzess with 15-20 ml lactose. Works 90% of the time with a restricting diet. Still drink a few beers. No liquor. Went through 12-15 gastroenterologists before finally getting relief. Finally had major back surgery 3 months ago. Healing well, went to have a torn rotator cuff fixed only to find out I have arthritis and cannot be fixed. Hope this helps someone younger. Life has been rough since retirement. Oh well, could be worse. Also take 2 Senokot before bedtime. Hope this helps someone younger."

For Constipation, Chronic "Developed digestive issues out of nowhere and became consistently constipated. Doctor said to take MiraLAX, but after 24 doses over a period of 24 hours, nothing happened. Stool softener pills? Nope. Adding 20 g of daily fiber? Nope. One dose of lactulose (30 ml) and I pooped in 14 hours. One dose a day has kept me regular. A miracle."

For Constipation, Acute "After three days of working on my small boat, I had extreme difficulty passing a motion. Very solid stool not going to come without a lot of effort. I never have problems, and I’m in my 70s. But I’d not eaten well, worked in awkward spaces, done heavy lifting, etc., and was probably dehydrated. Weekend and away from usual medical help. Wife overseas, away from family. I had read the book GUT by J. Enders some time back out of interest. Did the exercises she recommended to no avail and very uncomfortable. To cut the story short: Bought a bottle of Laevolac lactose solution over the counter. 30 ml down the hatch. Tastes great. Ate lots of fruity fiber. Two to three hours later, rear end all joy and back in business, albeit a little gas, but who cares? Men enjoy that. 12 hours on, all is bliss. Two sloppier poos and just now normal production. Bit of borborygmus but understandable."

For Constipation "I’ve suffered with IBS my whole life, but since becoming pregnant, I find it extremely hard to pass my stools. I don’t use lactulose every day, but I do when I haven’t pooped in a few days. 30 mL of this stuff, and it makes me poop in 2-3 hours, which is very quick considering it says it takes 2 days to kick in. The bulk-forming laxatives have never helped me as it hurts too much to push out the hard poops when I’m pregnant, and it takes too long to have an effect. The stimulant laxatives are also a no-no as I have a very sensitive belly from years of IBS, and all it does is make me cramp up. So lactulose has been a lifesaver, and I recommend it to anyone."
