ClearLax Reviews

For Constipation "I haven't used the bathroom like I was supposed to in the last month. I have taken Fleet and other laxatives, but they just did not work. I felt so bloated, and I never stopped eating. Finally, I couldn't take it anymore, so I went to the doctor, and she prescribed me something to take. The medicine that she prescribed for me wasn't covered by my insurance, so I went to Walmart and saw that ClearLax had almost the same ingredients. I bought some apple juice and mixed it together. About an hour later, I really used the bathroom, and I feel great. If it works for me, it is some good stuff, and I am serious."


For Constipation "I've been taking ClearLax for a little over a week now. I kept complaining to my wife for years about bowel movement troubles. She told me if I'm having so much trouble to buy some Miralax. I found ClearLax with the same ingredients as Miralax. Anyway, my constipation was driving me crazy and was painful. I was having trouble with hemorrhoids, stomach cramps, bowel movements, and etc., you name it. I no longer use Preparation H and feel great."


For Constipation, Acute "I was chubby for years and almost never had bowel movements. When I did, it was with pain so severe I nearly passed out. My doctor recommended MiraLax and I started taking it every night. I do go to the bathroom now and sometime multiple times a day. I feel so much better and have lost over 50 pounds over two years. I have blood work and a complete workup every three months, but so far, so good. Best part I am no longer a couch potato and work outside a lot and swim. It really changed my life."


For Constipation "I take bicycodil and 1 cap of clear lax (in water or Sprite/7up) before bedtime - it works brilliantly for me. Highly recommend that you at least try Clearlax; you don't have to use the dulcolax/major tablets with it but that's what works for ME .. so everyone's body is different. I have not experienced any upset tummy as I did with dulcolax; but with the major and clear lax, I feel perfectly fine and good to get on with my day after noon .."


For Constipation "Following horrific food poisoning, I became extremely constipated. Could not poop for roughly 2 weeks. I have IBS-C and ClearLax (polyethylene glycol 33350) is the only medication that has helped me. 3 days post taking ClearLax, I had a loose bowel movement that was smelly. But after I cut the amount of ClearLax from 17g to 10g, BM's have been relatively normal. Side effects: queasiness after drinking ClearLax with water, rumbling stomach, excessive gas, and looser BM's. there is a slight flavor to it, almost tastes like artificial cucumber. Highly recommend this product"


For Constipation "It works but is hard to regulate dose. I always eat a lot fruits and veg so sometimes I cut down dosage then stop going. Some others have results in a day or two, takes at least 3 to 4 days for me. Eating the way I do its hard to regulate especially having to wait for result. I really like the product, just sometime it works too good!!!"


For Bowel Preparation "I used it instead of Miralax because of the nice price, but soon regretted it. Clearlax made me extremely sick. I was very nauseated with vomiting, and no pooping at all (probably because I threw up everything). I poured it all out and bought more Miralax."


For Constipation "I struggle with constipation and other stomach issues. This stuff works better than almost everything I have tried. It gets things moving within 2-3 days after I take the first dose. I usually stick to every other-day dosing when things get backed up. I like to pair this with IBgard/FDgard. It works wonders. Highly Recommend!!!"


"I’ve been taking miralax for the past 3 days, and haven’t had any bowel movements? I’ve never taken a laxative powder but I have used duolex pills which are a whole different other experience in my opinion. But clearlax says it’s supposed to work within 3-4 days. The first day I took about 10g, and yesterday and today I took the full 17g, and still nothing. I guess we will see tomorrow... if nothing happens I think I’m going to go buy miralax."


"I am now 63, had many colonoscopies, this time I had to also do an endoscopy, so I came here and ClearLax had the highest reviews. I tried Miralax, which is another name for it, but for some reason ClearLax worked out much better. I drank it with my eight mixed glasses, with four of them 7-Up, no sugar, and could not tell it had prep in it. The other four had two different flavors of Powerade, and they also had very little taste of it in them. It helped clean me out with no problems, along with two Dulcolax tablets, and then I had two simethicone tabs for bloating and gas. I bought it all myself at Walmart for under $25. It was the easiest and best colonoscopy prep experience I've ever had. I will definitely stick with ClearLax, most don't realize it's your choice what prep to take."


For Constipation "I have been using ClearLax for 3 months, as I take many medications every day that constipate me. I have not had any problems and continue to take it every day with no problems."


For Constipation "The low keto diet my doctor put me on plugged me up a little, so I tried this product ClearLax, and it worked like a charm!"


For Constipation, Acute "Works too well. Forget going anywhere!! Set A Guinness Record For Number of Daily Poos. I have a sore ass so am getting getting off this stuff!!"


For Constipation "Take once a day. Effective but pronounced stomach cramps."


For Constipation "I take ClearLax every day and it works great. Only thing that has made me regular on an ongoing basis."
