"Once again I fell for a product despite knowing better. There is no such thing as a weight loss pill. Nothing. Weight loss comes from modified diet and exercise. There's no magic pill. Not only didn't I lose any weight... I GAINED another 10 lbs. This was a waste of money and I suspect messed with my metabolism in the process. The makers of this placebo should refund all our money. Total con."

"I lost over 20 lbs in 2008 & could only take 1 pill a day & the most was 2 a day & kept it off with just 1 pill a day, without out exercising because of back problems & couldn’t exercise. It was a miracle pill for me because it even helped my acid reflux when nexium & other meds’s didn’t work. But in 2012 when they had a shortage of them here so I started getting the orilast from India instead of the USA but it DOESN’T work. I’ve tried taking 2 pills at each meal & only got greasy stools but didn’t lose not 1 lb. I wasn’t immune to it either because I had to wait almost 6 months or more for it to buy otc again..Even tried the prescription brand as well & no difference..So sad that you can’t buy U.S.A. products anymore!!"

"Recently purchased alli tablets from chemist, after two weeks my liver and kidneys started hurting so much that I had to stop taking them. I emailed GlaxoSmithKline who said that they was aware that possible liver failure may result. As they originally removed them back in 2012. And they wanted me to sign a consent form (basically wanting me to keep on taking them as their guinea pig) for their research. "

"I also have had very positive results with Alli. I was only slightly overweight and now can say I am just a few pounds away from not being in that category any more. I read the insturctions in the starter kit very carefully and planned a good meal plan. I have not had any horror stories about the "treatment affects", but then again, I watch what I eat. "

"I used Alli for about three weeks . I didn't notice it helping me lose weight faster than I can with a weight watchers program . It did increase my bowel movements. I did have some stomach discomfort and gas. I stopped using it at the end of the third week because I went out to dinner and took my pill with my meal and it made me extremely ILL. Vomiting and Diarrhoea for over eight hours !!! I would not recommend this product to anybody !!! Weight watchers is working out very well for me . Eating healthy and exercise is the only way to go, there is no magic pill!!! I had to find out the hard way !"

"I have always been a small person but now I am 23 lbs. overweight for the 2nd go around again. I thought I would try Alli instead of going to get a prescription this time. It cost me $62.00 plus. I have been using it for 3 weeks and it does absolutely nothing to help curb your appetite, if anything, I seemed to eat more. So I thought I would try taking more than the suggested, well that did nothing either. I will report that there were no side effects or illness or anything like that which I have read on some postings. Alli was a big waste of money for me and I will just have to go and get a prescription again, which does work. Alli is Not a substitute for a prescription diet pill, no matter what it states."

"Don't bother. By the sounds of it... there's nothing beneficial in using Alli. Everyone stating successes here have said they have been on strict diets and exercising. DUH. That's why you're losing weight. Doesn't work if you don't do at least the "eating right" part. Nothing will. It's not a magic addition. I would say if you're going to diet and be healthy, do that. It's didn't add any value in my opinion."

"I started ALLI on Saturday 16th. I took all 3 pills throughtout the day with my moderately fat diet and its now Tuesday 19th and I've not had one oily stool or 'accidents'. My flatulence has increased and I have a gurgly sensation in my belly once in a while. Just wondering if these things are going to work. I will weigh myself in a few days to see"

"My doctor suggested Alli to help me lose weight. I took the medication for 6 months at twice the over-the-counter dose. I ended up gaining 10 pounds during the six months because I consumed too many carbs. Side effects were not an issue for me. My doctor told me to stop taking Alli and switched me to a keto diet. The keto diet has been yielding good results for weight loss. I rated the medication a 5 out of 10 because I don't think that Alli was the reason that I did not lose weight. I failed to watch my calorie intake while taking Alli. I also recommend Alli to those who are able to get on a calorie-restricted diet while taking the medication."

"I have been using Alli for a number of years, and I echo what many have already said. Alli seems to work in two ways, (1) Medical, by inhibiting the absorption of digested fat and (2) by offering a direct and timely feedback loop. Eating a high-fat meal? Alli will let you and your toilet know within a matter of hours. After a while, you learn to understand the relationship between food and fat. I have a small pill box of Alli that I take with me wherever I go, so I don't miss it at mealtime. With Alli, timing (both input and out) is everything."

"This was the worst decision I have ever made, taking this pill. I am only about 35 pounds over weight and I joined a national company and attend meetings. I started having orange bowel movements. There were droplets of orange oil all over the toilet bowl. I constantly dripped the oil and it was such a mess. I dumped the bottle in the trash. I will stick with my program and just lose a bit more slowly. Thanks for nothing Alli!!"

"This pill has worked for so many people so I thought I would give it a shot. I go to a dietician regularly for food allergies so my diet is already very healthy and effective. I took Alli not only for weight loss, but mostly because I had heard from friends it would help keep me regular. I will say if you cheat on your diet do not take Alli you will have oil movements instead of a normal bowel motion. However, even in my instance Alli caused me serious stomach issues. Although I did not have accidents I did have feelings that I was not going to make it to the restroom or extreme gas. This pill all depends on your body chemistry. Even with a good diet sometimes it will not work. However, I did start taking a veggie fiber after Alli and it has great benefits"

"I have never had kidney stones and started taking alli 1-2 times a day a few months ago. I was just taken to the hospital for a kidney stone. I have not changed any other meds or anything else. I believe the stone is a direct result of alli."

"We all know the side effect about diarrhoea of those pills but it's totally not candy. As a diabetic type 1, I do blood test every 6 months to watch if the function of my kidneys. My blood test is very bad after Alli. The kidneys are really tired cause of Alli. ALWAYS ask your doctor before using it. Alli is not candy, not natural The first week I loose 3 pounds and that's it. So no... it's totally don't worth it."

"I am reading all these great things about Ali and I’m so disappointed… I got so Very ill after I took it. I honestly thought I was going to die. I’ve looked for drug interactions and I can’t find any with the medication I take. I’m on an opiate pain reliever for my back. I took Ali with my lunch and felt like I got the flu within an hour body aches chills almost like I was withdrawing from my pain medication. But then I read and searched on the Internet and didn’t find any interactions so I took it again with my dinner . This time I broke into a sweat, profusely sweating had chills so bad that was violently shaking was so dizzy that I couldn’t even stand up I was nauseous, My muscles started cramping up and I couldn’t breathe…(I might have been panicking and I do have asthma ) and then after about two hours it went away again. It was a very scary experience and I thought about going to the hospital but I couldn’t even walk across the room to get to my phone."
