For Constipation, Acute "Wow! I took 60 mL of lactulose and OH WOW, two hours later my farts became atomic. They kept coming, one after another - shooting out like a machine gun. Once I raced to the toilet, it was as if a hydrogen bomb had gone off. The back splash was a deluge, almost a tidal wave. It was mind-altering."

For Constipation, Chronic "Just start at one tablespoon (15 ml) and then start increasing the dosage by one teaspoon (5 ml) every day until your bowel movement is soft. There are very few complications. It can be taken safely for decades. In fact, you may have to increase the dosage over time."

For Constipation, Chronic "This worked well to soften hard stools and make straining unnecessary, but it surprisingly gave me an irregular heartbeat after taking it for two weeks. I did not realize what the source of the irregular beats was for a few days, but when I stopped taking the lactulose, my heart was back to normal in a couple of days. It could just be a coincidence and unconnected to the lactulose, but after digging deep into an FDA site, I found that 5% of users find it can cause some type of heartbeat irregularity - AF, palpitations, slow beats, fast beats, etc. Hope that is useful to someone."

For Constipation, Chronic "Have suffered constipation for 45 years, having tried everything doctors prescribed me - did the high fiber diet, you name it, I've tried it. I discovered lactulose 4 months ago and wish I had discovered it years ago. I have the right dosage for me down to a T so as not to suffer cramps or embarrassing wind. For me, it has been great, I'm not sick with constipation anymore."

For Constipation, Acute "I was given this bottle of Lactulose by the local hospital where I am currently undergoing chemotherapy for cancer. My constipation causes me more pain than I can describe, the cramps and vomiting have caused me quite a few sleepless nights. I felt the pain coming on at about 3 in the afternoon and was expecting to be in agony by 7 pm. I took the Lactulose at about 3:30 pm and by 7 pm, I was alright, and the cramps disappeared, and no vomiting. I cannot state how much relief I felt knowing that I would get a good night's sleep without pain and constipation. I've just rang my family to let them know that I've finally found something that gives me relief without grief. Best yet."

For Constipation, Chronic "I have suffered from terrible constipation my whole life... I'm 61 now. I eat tons of vegetables, drink lots of water, and have tried Fybogel and other bulking agents. Nothing worked! Three weeks ago, I had an operation and was advised to take lactulose to avoid straining my wound. Well, what a transformation. Since then, I take 30ml per day and have a perfect bowel movement daily. I only wish I had discovered lactulose earlier in my life. I'm lucky in that I actually enjoy the sweet syrup, and I suffer very little wind at all. Everyone's different, but I would definitely say it's worth a try."

For Constipation, Chronic "I have been severely constipated on and off for four years. I have tried other laxatives, they barely worked for me. Before my doctor prescribed this to me, I couldn't produce a bowel movement for a month. I was really sick, I couldn't eat or drink for days at a time. I was running fevers, I couldn't walk, and I was fainting. I take 90 ml three times a day. It's a really high dose, so be sure to take your own recommended dose, but I can now use the bathroom at least twice a day. My stools were literally compacted, and now I am all cleared out. I highly recommend this medication."

For Constipation, Chronic "I'm on lactulose 15-30 ml for almost two years. I've had constipation my entire life. Until I was four, I thought it was normal. I've bounced from specialist to specialist. Nobody can give me a diagnosis, but all I knew was the feces buildup was releasing toxins into my body and it was just unhealthy. An x-ray of my torso showed that the buildup was literally putting pressure on my lungs and it had impacted my breathing. Specialists gave me one of two options: laxatives or surgery. So, I tried countless laxatives, diets, exercise regimens. The only thing that's helped so far in my 15 years of life is sennas and enemas, both of which are extremely painful and give me awful diarrhea. Until lactulose. It's helped tremendously, and I can have natural movements. The only uncomfortable thing is all the flatulence, but that's better than curling up into a ball in pain."

For Constipation, Chronic "I've taken codeine and morphine for a long time and have been constipated for years, on and off. I've tried senna, Movicol, and they'd take at least 5 days to work. And the taste of 2 Movicol sachets with 250ml was yuck. Also made me bloated. I've started lactulose on 15ml 3 times a day, but around 2 hours after taking 15ml, I was going to the bathroom! It's very convenient too as I just add the 15ml to a drop of juice/squash. Very happy to have found something so good, but it does cause me a lot of wind."

Lactulose for Hepatic Encephalopathy "Initial symptoms included brain fog, disorientation, and confusion. I took the lactulose for one week... all symptoms disappeared. However, I must advise you to stay close to the bathroom. Also, I should note that my physician said that I may be taking this medication for the rest of my life and I'm only 47 years old."

Lactulose for Constipation, Chronic "This was the only treatment that worked after my hemorrhoidectomy - had to go to the ER to get this prescription though after three days of constipation from the pain meds - too bad my surgeon did not prescribe this to me earlier."

For Constipation, Chronic "I have been on a large dose of Morphine for years for my worsening back problems. I have gone as long as 8-10 days without a bowel motion. Lactulose is the only thing that has worked. Usually within 4-6 hours I will start having BM's. I haven't had any side effects, not even cramping. I use 15 to 30 cc on an as needed basis. I did read that you should not use Lactulose if you are diabetic because it is a sugar."

For Constipation, Chronic "This is a miracle. Taking Oxycodone makes you so constipated, it's not funny. I take 80ml-100ml, which is a dose I wouldn't recommend to someone taking it for the first time. Start small and see how it works for you. I take it right before bed. And by the time I wake up, it's toilet time, every time. Sometimes I will get a slight pain in my stomach during sleeping and it can't wait till my usual wake-up time."

For Constipation, Chronic "I've suffered with Irritable Bowel Syndrome all my life, got worse in adulthood. Mixture of constipation and diarrhea. I'm now 6 months pregnant, got no more IBS cramps, but painful gas that doesn't pass. I took this for the first time in my life this morning at 9 AM. Took 30mls as suggested by the pharmacist. Only ONE hour later and I'm having bowel movements and a lot of wind. No pain or cramps for once! Only thing is it's been non-stop toilet runs for 10 hours."

For Constipation, Chronic "12 weeks pregnant and constipated really bad with no movement for nearly 7 days. I had a really bad tummy ache and I couldn't take much while being pregnant. The pharmacist gave me this (liquid) and after about 4 hours, it was gone. I was so pleased. It's the best thing I've ever used for constipation."

For Constipation, Chronic "Doctor prescribed 3x/day. It worked and still works wonderfully after 7 years. But, 3x/day was too much. I decided nightly before bed, and it works GREAT. Sometimes I have to take a double dose, but I'll tell you, this medicine is a dream come true for me as when I am not going (I have irritable bowel syndrome with constipation - IBS-C) I get sick as a dog: nausea, cramping, lightheaded, and more. Don't be afraid to experiment in the beginning to find the right dose and dosing schedule for you."

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, 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."

Lactulose for Constipation, Chronic "I’ve been struggling to have a bowel motion for years. I am on a high dose of OxyContin and Oxycodone daily due to pancreatic cancer, so I have what they call opioid-induced constipation. I was going two weeks without having a bowel motion, then my doctor started me on Generlac, and it works wonderfully. I took 30ml for the first dose, and 24 hours later, I was on the toilet. I take 15ml daily to keep me going. No cramping or diarrhea... just a little gas."

For Constipation, Chronic "This drug is a miracle worker, as I have MS and slow digestive transit. As a result, my stools dry out and I can't go for 7-8 days. Taking only 25 ml of lactulose every second day does the trick, no bloating, no pain, just regular movements that are normal to pass. A side effect for me is, yes, wind-normally 4-8 hours after taking the dose, but 4 hours of wind is a small price to pay. It is very sweet, sweeter than sugar, but I actually like it, I must have a very sweet tooth. It’s in no way unpleasant to take, just sweet."
