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 20mls 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, 2hrs after my 3rd dose, I feel about 5 kilos lighter. Im 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. PS. I'm in New Zealand where a lot of medication is funded by the government."

For Constipation, Chronic "Given lactulose for chronic constipation from IBS. At first it wasn't too bad, but then I started getting severe gas pains, lots of gas, abdominal pain and nausea. Yes it worked for the constipation, but I felt sick all the time, and it made IBS pain much worse"

For Constipation, Chronic "I had surgery on my stomach and was severely constipated after it was agony to go, I was prescribed lactulose but it’s far too sweet and syrupy I gagged every time I tried to take it even when I mixed it with other liquids. Even the thought of taking it made me gag, and it didn’t help at all when I needed to use the bathroom I used it for about a week and still couldn’t go without being in agony. I switched to dulcoease capsules and they worked the same day!"

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

For Constipation, Chronic "I was prescribed lactulose at 10 ml, 2-3 times a day. It looks like syrup and tastes like a syrup with a lot less sugar in it. I did not suffer from cramps, but did pass a lot of gas while taking it. Also, it did improve my constipation quite a bit so I'm happy with it."

For Constipation, Acute "Try different ways of taking this medicine lactulose. For me, taking it the way the label said just didn’t do anything. It caused major and very embarrassing gas. Honestly don’t leave the house the day you begin this dosing. What I found was it hindered my sleep because of the gas, a lot of tummy rumbling, luckily was sleeping alone that night. Don’t underestimate the frequency of the gas either, constant. I think try out different ways. I take 1 entire capful, and that usually does the trick. Just don’t make any plans for that day."

For Constipation, Acute "4 days of suffering, nothing was coming out of me despite 30 times of trying, also had lot of pain at kidneys. I had all the Fibre foods, drank gallons of water but nothing!! One of my friends suggested Loose syrup which I drank 40ml. Finally I felt some pressure, took my chance but the size of the tool was so wide that my body was under sized. What came next is graphic but I literally had no choice. I had to manually clear some of the hard stool out of butt. Passage still felt super small for the huge train but I had to push it so hard, it felt like I was giving birth as it exited me. What followed the impact stool was runnier and everything was just free flowing. This is super painful experience and I now understand what others go thru. If my experience could be of any help, the medicine is for sure effective but took 8+ hours to show results with lot of my own efforts to make it work"

For Constipation, Acute "I have an anal fissure which is very painful if my stool is hard. Each time I go to the toilet the fissure can reopen and the healing process has to start again. Taking lactose has soften my stool so giving my anal fissure time to heal. I take 15ml once a day before bed with a cup of water. Certainly makes life in the morning a lot less painful."

For Constipation, Chronic "Hubby is having chronic constipation. Many of us will when approaching 90. He used and still uses Casgara Sagrada (which never loses its potency. You don't have to take more and more.) This lactulose seems to work for him when he takes it regularly. He is also now taking two tablespoons of ground flaxseed stirred in 8 oz. of liquid daily. I do not have constipation now although I did as a child mainly from poor diet and not drinking very much water. A former mother-in-law religiously chewed a few slices of apple with some stewed prunes every night before bed. I understand that now she is 102. What a surprise!."

For Constipation, Chronic "I've been taking it for about 2 weeks twice a day. Indeed it causes some very funny noises in my tummy, which my kids find hilarious. I definitely have the passing gas issues as well. Although my kids seem to have some giggles, I find it a bit embarrassing. It does work wonders for my issues, as it works within a few hours of taking it."

For Constipation, Chronic "I passed gas and a bit of abdominal discomfort the 1st time I took this med, but the side effect of the 2nd time is worse. Although defecation occurred one hour after I took the med at 10mL dose only, I experienced painful bowel cramping last for hours into early morning."

For Constipation, Chronic "Absolutely brilliant. You must drink lots of water for it to work. Having been very constipated my Pharmacist advised 40ml twice a day but I only needed one dose at this amount. Would definitely recommend it."

For Constipation, Acute "I started to take this the way it says on the label, 15ML twice a day. It did nothing for me other than cause terrible, vile flatulence. The smell was like a sewer, and zero relief. Annoyed after about 3 days, I decided to take more. So I took 60ML in one. Within 2 hours, I had had a bowel movement. In the end all that came out was liquid. There seemed to be less flatulence also. I find it’s sort of unpredictable when you take it day and night, you may or may not have a movement the next day. Or you might, and it might not be satisfactory (could be very small, still feel like you need to go after) which is very almost upsetting really when you know what it’s like to suffer so much from constipation. The flatulence ends if you take it for a few days it’s as though ur body needs time to get used to it. If you’re going to use this, use it on a day when you don’t need to be anywhere or meet anyone! Take the 60ML and take it with a warm drink to help it along."

For Constipation, Chronic "I have been using lactulose for chronic constipation for three years. It is very effective. I now find that the sweet taste is making me gag and/or vomit. There are times when just looking at the bottle invokes the nausea. I have mixed in other liquid so I can't taste it, however I can't take it anymore. Any wise ideas?"

For Constipation, Chronic "I have IBS-C and it's slowly been getting worse over the years (I'm 26). I've tried everything from MiraLax to enemas. After 2 ER visits, I was prescribed 30mL of lactulose. Well, I took one dose and nothing happened, but that's because I didn't realize I needed to drink a boatload of water with it (you should drink at least 1-2 full cups of water after taking the dose). A few days later, I tried again, this time with a ton of water, and holy moly, did it clean me out. It wasn't painful; cramps weren't even that bad, just more like a lot of grumbling from my gut, and the more fluids I put in, the more my system "cleaned house." Sweet relief! My only qualm is the gas pockets afterward, which got a little uncomfortable, but at least I was able to go!"

  • December 8, 2016

For Constipation, Chronic "I have had chronic constipation since 5 yrs old I had chronic pain from a condition I was born with, and at 30 received oxcontin for the pain other wise I would be in a wheel chair. As a child after eating I would bloat I still do even on just 2 cups off coffee, it has taken 4 days for lactulose to work but I feel a lot better my Doctor said water water water! as the lactulose draws the water into our bowels, she also mention try the msp diet as you can be misdiagnosed as IBC and it could be certain proteins and sugars as well as wheat, barley, beans, dairy and makes it too hard for our gut to process."

For Constipation, Acute "I occasionally use this lactulose for severe constipation most often caused by drugs. I don't find it works straight away. I have lymphocytic colitis and ibsd so my gut is very sensitive. Yes, lactulose is effective but very quickly the frequent farts become smellly and toxic. I stay away from people because of it. Over a few days farts start to expel little bits of poo and I soil my pants. I become too frightened to fart when out. I also can't tell the difference between a fart or a poo so I have to go to the loo every time just incase. Bit of a nuisance when it turns out to be just a fart. For those without lymphocytic colitis and ibsd its probably fine. Don't be put off by my experience."

For Constipation, Chronic "I have a motility problem after some of my bowel was cut out after diverticulitis. Then 2 Hernia's repaired. I have no sense of needing to go to toilet at all. I have to take either Lactulose or Magnesium sulphate to empty my bowel twice a week. I prefer Lactulose, it's easier on my bowel it doesn't make my bowel as sore as magnesium. I take 60ml of lactulose single dose twice a week. Sure there is some flatulence but it works fine."

For Constipation, Acute "If you don't mind the overwhelming feeling of urgency and flatulence, you can take 5 tablespoons of lactulose along with a bowl of bran cereal for breakfast. No matter how hard they try, most people won't be able to hold back the results after 4 hours."

For Constipation, Acute "My Dr prescribed a bottle of this 45ml twice a day. Had very little effect me, just a few tummy rumbles. Dr then decided I was partially impacted and prescribed Movicol 3 times daily. Did clear the impaction after 8 days. Now use Lactulose 30ml twice daily after my IBS diagnosis. Keeps me reasonably regular."
