Generlac Reviews

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 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."


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've been having constipation problems for awhile now. I tried linzess and it worked just a few times, like 2 or 3, so I went back to the Dr 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 everyday and I'm hoping it keeps working."


For Constipation, Chronic "Only thing that actually works!"
