Xenical (orlistat): "10/06/19 I started these no side effects for first 3 days , but 4th day , loose orange stools , but that I can live with that. I am on my 4th day now and lost 6lbs .. can't believe it"

Alli (orlistat): "The new generation of Orlistat, sold over the counter as Alli, does NOT work. I was on Xenical when it first came out in the 1990's. It worked very well and the orange discharge was a daily thing. Now 4 months ago I purchased Alli over the counter. Paid $85 and was very disappointed to find out that I had wasted my money. First, each pill is filled only 60mg instead of the Xenical which is 120mg so it is not the same dose. Second, even when doubling up doses it still does not grab the fat and produce the orange discharge like the old ones used to. I will never purchase this again. It is basically a placebo. I tried the keto diet for awhile to help with weight loss but the constipation & limitations were so horrible it didn't work. Also tried Phentermine and it too was unsuccessful in the long run. What works? The MY PLATE model, using a toddler sized sectioned plate."

"This medicine is a life saver. I was up to 200 lbs, in January 2019. Today I’m down to 174. Plus I struggled with severe constipation for years. I now just go once a day. This medicine is wonderful."

Alli (orlistat): "I've used these many of times over the years and always found they helped a lot. Started taking these a month ago and lost almost 2 stone already "

"Being given orlistat less than a week ago, I cannot say about weight loss but this review is about side effects. Oh my goodness, feeling as though you need to poo all the time, explosive farts with orange oily residue, that also leaks in underwear so you have to be careful what colour clothes you wear, not good, not pleasant. Also the oily residue does not flush away but sits on side of the toilet, I'm stopping taking it it's not worth it."

Alli (orlistat): "I took Alli because I just wanted to shed 15 pounds. At first I was starting to lose weight but then I ruined a few pairs of pants and a bedsheet thanks to the embarrassing and unexpected oil leaks. lol. Needless to say, it’s not worth the discomfort and embarrassment of being out in public and not knowing if/when you’ll have a very noticeable accident."

"So last October I went to my doctor and I begged for help as my weight really depressed me. So he put me on orlistat and now 6 months down the line am 16kg lighter, I've gone from a size 18/20 to 12/14. Best thing I ever did."

Xenical (orlistat): "Started taken xenical on Saturday 23 March 2019 weighed in at 95kg it’s now Monday 25 March 2019 and I weighed myself I’m already 94kg I haven’t had any major side effects I’m a bit more gassy than normal my stools have changed to a orange colour but not been caught short I just feel the need to go to the bathroom more often I will add a further review in a week or so to say if any side affects have changed"

Alli (orlistat): "I used Alli years ago and it worked awesome, I lost a lot of weight in a relatively short amount of time. They took it off the shelves for a period of time and then reintroduced back to the retailers. I have tried it several times since the Alli has been back on shelves and it is complete garbage, waste of money and time. I could drink a whole bottle of olive oil and have absolutely no effects. What a waste........I meticulously follow the directions and it does not help shed any extra pounds."

Xenical (orlistat): "I started Xenical 120 just over 2 weeks ago. I only take 2 tablets a day and watch my fat intake. I use an app called My Fitness Pal - where I log everything I eat and it comes up with Carbs, Fat and Protein for everything I eat. I only eat around 1000 calories per day, do not eat chocolates, lollies, chips etc. I do note that my carb intake is sometimes higher than the daily 50% allowed. Could this be stopping me from losing weight? I exercise by doing Aqua Aerobics (high intensity) for an hour at least 4 - 5 days per week. I desperately need to lose around 15kgs but feel that I’m not doing something right. Is 2 weeks too short a time to tell if it’s working? I don’t own scales and have been told to go by my clothes. I have a back injury so cannot walk very far "

Xenical (orlistat): "This has been a miracle drug for me! I have tried and failed many times at dieting. I could not lose weight. I am type 1 diabetic, and I just kept packing on the pounds. Finally, at 271 lbs, I asked for help. In the U.S., my insurance would not cover the cost of Xenical. It was going to cost me $600 a month. Fortunately, the clinic has a prescription assistance program, and I am able to get it for $15 a month. I found out real quick what I could eat and what I could not eat. There were a few days spent on the toilet, but I learned to modify my eating. Xenical does not make you jittery or fill you up. It works in your stomach and gut. I went to my weight doctor yesterday, and in three months, I have lost 33 lbs without much effort at all!!! I am now 238 lbs, and do not need to sleep with my sleep apnea machine. I feel great and people comment that even my complexion looks better. I am still taking Xenical, and still losing weight."

Alli (orlistat): "I am not obese, just wanted to lose 20 lbs that I have not had luck shedding over the years. I have been taking Alli for 3 months now and have not lost any weight. It did however, help me from being constipated. If you're having trouble pooping, Alli will help."

Alli (orlistat): "I have been taking Alli for 2 weeks I changed my diet started eating healthier and have gained 3 pounds there are times I'm not sure if I will make it to the bathroom in time I go to the bathroom 4 or 5 times a day now and it's mostly yellow oily liquid. I'm throwing them away what a waste of money"

Alli (orlistat): "These do not work any more like they did back in 2010 .You took out the ingredients that really worked WHY! Friends will definitely know not to but these they don't work .Waste of my money now."

Alli (orlistat): "Years ago my doctor put me on Orlistat which worked wonderfully! I was able to easily lose 10-15 pounds in the first month which in turn motivated me to keep going even without the pill. Now years later when the same medication is over the counter it is half the strength as when it first came out. It never seemed to work as good. So this time I decided to give it the benefit of the doubt & take TWO to see if it would work the same way is used to….Needless to say it did NOT! One night while taking the pill out, I placed it on top of my dresser. The light from the bathroom hit it just right and I noticed something. I held the Alli pill up to the light and low and behold it was not even HALF full! You have taken something that actually worked for countless people without any serious side effects and turned it into something worthless! I again have wasted my money on your product when I can get better results from eating half a pack of sugarless gum! Thanks for nothing…."

Xenical (orlistat): "I started taking Xenical (Orlistat) almost a week ago. Im 5.3 and currently weigh 162lbs. I gained about 30 pounds after 3 and a half years of using Mirena IUD thats why I started taking Orlistat because nothing was working, it seemed as if my metabolism had been shut. I eat about 1200 calories everyday, I workout 3 days a week and I get around 6000 or more steps a day. So for the first 3 days I had no oily side effects but on the fourth day thats when it really kicked in for me. So far I haven't really lost any weight if anything I've gained about 2 pounds but I'm not sure if that's because I've been working out and my body's retaining more water, I also have my monthly visitor so not quiet sure yet. But I will keep you all updated after 2 weeks."

Xenical (orlistat): "Ive been with slimming world (SW) for over a year, I lost nearly 15kg (33lb) and still have 15kg to go. My wight lose ground to a stop as I have done so many times before but this time decided not to give up. I'm using xenical along with SW and lost 2kg in my first week. I have not had any of the side effects but SW is low fat anyhow. I have underactive thyroid RA and OA. I have had 2 knee and 1 hip replacements, 1 toe fusion 1 trapeziectomy in the last 3 years. Fingers crossed losing the weight will also help my poor joints. I would recommend it along with a low fat low carb diet. It is not a miracle cure but if you help yourself it will give you that little extra boost"

Alli (orlistat): "I started taking Alli 2x a day 10 days ago. I only had 15 pounds that I've been struggling to lose. It's curbed my appetite and I've lost 3 1/2 pounds in 10 days! The only Con if you eat a high fat meal you will be stuck on the toilet tomorrow morning. It will definitely remind you not to do that again. What I love about Alli no jittery diet pill side effects and rapid weight loss."

Xenical (orlistat): "I started Xenical two days ago and I've already lost 2 kilos. Yes the side affects aren't the best but I can live with them if this is the results. My pants are already loose on me! I have no experienced any side affects besides loose bowels and oily stools depending on what I eat. It is a little pricey is Australia its about $97 a month but its early days and I feel so much better, I am willing to pay the price!"

"Diagnosed with significant osteoarthritis in both knees and Dr decided to give Orlistat a try to help reduce pain quickly. I was extremely wary because of all the horror stories you read online. I have been taking 120mg x 3 per day and in 6 weeks have lost 11kg. I can honestly say that I have not had ANY side effects whatsoever . I have an app on my phone where I record EVERYTHING that I eat and drink. I take photos of EVERYTHING too so I know exactly what I’m eating. I worked on a 1400 calorie per day with no more that 40g of fat over 3 meals and 2 snacks. You have to change the way you think about food, if your serious about losing weight and feeling better then you have to make changes. Orlistat isn’t a wonder drug nor is it going to do all the hard work for you BUT if you change your mindset, move more, and eat a healthy balanced diet you will see amazing results. Well, I have "

Alli (orlistat): "I started taking Alli the other day. I have had to purchase Poise pads, just in case of an oil gas or stool. I have read nothing but horror stories. But I am just experiencing extra bowel movements in the toilet. Mild stomach cramps. I wear the pads in case of anything due to side effects, but have had nothing at all. Lost weight already. But I am not hungry at all. I tried out the first day on a Sunday in case of adverse side effects. So good. Hopefully this can be my go to for weight management going forward."

Alli (orlistat): "I took Alli 11 yrs ago only for less than 2 months and I still have all the side effects. I had my gallbladder removed, diagnosed with liver disease and do not feel like a myself anymore. Do NOT take these pills."
