 5  Lose weight None I am a healthcare professional. I give out box after box of xenical. I have done masses of training on this medication, and I will tell you this for fact - THE ONLY WAY YOU WILL GET THE SIDE EFFECTS IS IF YOU DO NOT ADHERE TO THE INSTRUCTIONS! It partly disables an enzyme in your gut called lipase, which breaks down fat, so it cannot be broken down and absored. About 30% of your dietry fat will be expelled. There is physically no way you can get such explosive side effects if you adhere to the instructions - there would not be enough fat in your system for this to happen! So take a good hard look at what you have eaten, every little thing you added to food, and ask yourself again if you adhered to the fat allowance. M 27 3 days

 5  Over-weight, High BP & Cholest. Less bowel movements??? I have really been watching my fat intake. Almost to the point of Hardly any at all. I did go to Outback Steak house 1 day...husband ordered cheese fries..I had not even 1 cup....Oh did this pill work! But I did that for a test. As long as you eat very low fat intake things should be pretty normal. My weight loss in 2 weeks has been approx 8-9 lbs. Ive tried everything....."I Hope this works" M 40 2 weeks

 5  Cholesterol, weight. Orange oily fluids released 4 hours after the fist time I took one pill! The pain in my wallet! So expensive. Combined with a healthier diet, less alcohol and brisk walking I dropped 15 pounds in 3 months. I will add that I take two anti-depressants, one mood-stabilizer, and have still been able to lose the weight whereas before taking Xenical, I could never have done that. M 42 75 days

 5  obesity Oily, fatty stools, sudden and immediate urgency to Works well, lost 35+ pounds in a year. The annoying side effects actually provided incentive to remain on a healthy,low fat diet; the price paid the next day for cheating with a few slices of pizza, for example, just are not worth it, and any binge or visit to a Las Vegas buffet exacts a heavy price and possible clothing loss. After awhile, my eating habits and preferences changed thanks to the psychology provided by the gross-out factor, and I have not gained the weight back. That I believe is the M 45 1 years

 5  Weight Loss Oily stools, orange toilet pan, risky farts, mild stomach pain All in all this drug is sensational imo. I use it together with exercise and have lost about a stone in a month. For anyone taking Anti Depressants, it certainly works to counter any Weight gain from AD's which is what Ive been looking for for years. Side effects really can catch you out, but are well well worth it if being a porker gets you down!! M 32 40 days

 5  Fat blocker If you cook/make your own food, very little oil in pooh. But if you eat process food - lots of oil. Thai, Indian, Chinese also lots of oil !! It is amazing how much oil is in some foods. Butter on toast - no oil ? I only take one at dinner for a fat blocker. Also when I go out to restaurants. Also on holiday I take 3 a day. basically any time I eat out. I think these are the best pills to keep your weight down. M 46 2 years

 4  weight loss lethargy, itchy / sore anus, increased flatulence and the dreaded oily turd. Most of my weight problem stems from a) being a chef and eating all day and b) drinking too much alcohol. I've managed to get down to 88kg from 95kg in one month taking this drug, with only a modest adjustment to my diet. I'm finding the side effects amusing more than inconvienient but I guess thats alright for me being a bloke! I feel sorry for the ladies though... M 34 1 months

 4  Overweight Loose stool, orange oil, not much more gas, more frequent bowel movements So I've been on it for about 2 weeks. After a week I had the dreaded 'accident'. Went to fart, and it wasn't a fart. Not a pretty sight. Though I did have pizza and wings the night before. Xenical mainly teaches you to eat better. You eat like crap, and you suffer shortly after. I am trying to eat better. I've lost about 1 lb since I started. M 28 14 days

 3  To lose Weight Fatty or oily stool, Uncontrolled & spontaneous bowel movements, Increased frequency of bowel movements, Unexplained rash, Headaches, Abdominal pain In my country, you don't need any prescription for this drug and you just go to pharmacy and buy it. First started in 2002 and same side effects i mentioned. Till 2006 i took 2 Xenical tablets before meals. It kept me no matter what i eat in same weight that time. But i decided not to use it later because of the warnings of some doctors. After stopping this medicine i started to gain weight and believe or not i put somehow 50 pounds in 3 years time. Then i decided to use Xenical once again, in fact it did not make me lose weight and side effects came back. Now over a year now, i use Xenical, and it don't make me lose weight, even gained few pounds. I think if u use for the time period, it helps to stay in same weight. But if you give a break later and restart this medicine, you don't lose weight at all. Side effects can occur as we all know and no need to mention especially within 1st & 2nd year and lessens afterwards, but oily thing never goes away. I think it works for not everyone but some and if you stop taking it, then never ever restart Xenical because it don't help at all. Somehow your body get used to this medicine and restarting it, don't make you lose weight at all. I understand now. All we need is to reorganize our diet and lose weight. Drugs and all medications is not the answer of weight loss. M 41 8 years

 3  lose weight some "treatment effects" - oily stools, sudden urgency I was already pretty good at sticking to a low fat diet, but I am amazed at how much fat and grease I am passing even when sticking to 45 G of fat for the whole day (no more than 15 at a meal). Hey - better out my behind than on my hips! The side effects are not as bad as they sound -- at least if you eat relatively low fat. M 51 2 weeks

 5  Weight I have had the usual bowel movements with oily stool. I have good control so have not experienced any accidents. I experimented with this first week and have not changed my diet. Would you believe I have lost 2 lbs regardless. When I start going to the gym and cut some of the fat from my diet, weight will drop off of me. I cant barely wait. I know the side effects are unappealing and can actually be uncomfortable, but if you cut a good amount of fat from your diet, you cant go wrong. Yes, it is expensive, but since when has losing weight ever been easy or cheap? F 33 7 days

 5  Lose weight for daughter's wedding Constipated first couple days, then the usual oily stools (or worse!) with too much fat intake. Works for me. It keeps me from cheating on my diet. It's simple, if you eat too much fat you may not make it to the toilet in time. And it's not like you can eat fat and not take a pill to escape the side effects because it stays in your system for several days. You can still have a drink because alcohol is sugar, not fat. When I need something sweet I eat licorice which has no fat. F 54 4 months

 5  Weight loss after having a baby Orange stools, slight headaches I have been taking xenical for one week, alongside a relatively low fat diet and have lost (to my surprise) 3kg. I haven't been that carefull with the amount of fat I have eaten and have been caught out once. Towards the end of the week though I started to become a little constipated, has anyone else experienced this? I'm pleased with the product and hoping that the weight loss will continue :O) F 30 7 days

 5  obese teenager in the first couple of weeks i didnt get any side effects, i felt great and completely normal. yesterday was the first time that i had orange, oily stool. this can be explained though, because i ate kfc and didnt watch my points that day. it wasnt bad/painful though. i weighed 120kilos when starting xenical, honestly it has changed my life. i cant remember a time when i loved shopping, my body and clothing so much! i wore a size 24-26 for the past year, which is horrible as a teen in highschool. in just four weeks im now wearing size 18 jeans! big big big improvement, i cant believe it. i can now also fit into (the biggest size though) of normal clothes, not pluz size for once! i currenty weigh 112kgs. its great, i dont feel like a burden to myself, family or friends. its now october and ill probably stay on xenical until january, just to get over the xmas period. xenical is great, i havent had any side effects and it has boosted my fitness, confidence and ability to love myself.. email me if you wish for any other details.

 5  Obesity One incident of dark orange oil in my stool but that was because I had 2 slices of pizza that had 12g of fat EACH. So far this has been really good for me. I haven't actually weighed myself yet but I certainly feel smaller. A lot of people on here are saying that they're experiencing really bad side effects, but then they say they're eating about 12g of fat with every meal. It's no surprise if you're eating that much! The most I'll have in one meal is 7g. The pills work wonderfully but only if you cut down enough. F 18 6 days

 5  obese only slight hunger pains due to less/healthier food consumed than previously this product is great! although expensive, ive seen results. i feel fine and normal in every way. just make sure you keep under the 30gram limit fat intake or you will pay in leakage and disgusting toilet habits. there isnt much help on the internet for a diet under 30grams so ill give you a typical day for me: four strawberries, a banana and a kiwi fruit for breakfast with a dollop of low fat yogurt on it - 2.5grams museli bar - 6grams steamed brocolli, carrot and potato with chicken - 12grams vita weats with vegemite - 3.5 grams grilled chicken breast with white rice and side salad - 6grams this can be varied accordingly. i find xenical great and im thankful for this product and my weight loss!

 5  to help me loose weigh Lot of gas in my stomach. A bit rash on my skin, But I think Is due to thefact that my body is expeling the fat. Nothing major. Firts of all I want to say, I exercise every day. 40 min on the bicycle, 45 to 1 hour running/walking with the dog and a bit of weigh and sit up. Is hard! Before start xenical I was 81kg. In 3 week`s time I lost 4 kg, the exercise and xenical together done the job. There is one problem only. Gas in my stomac. When I`m home is fine, but at work is really unconfortble, I need to run to the toilet every 30min and hope noone is there. If I don`t go it hurt. I know is not the solution, but is helping me alot. Once I reach my ideal wiegh I`m gonna stop xenical and keep going with the exercise. I`ve done soo many diet nothig really work, but since I change my life style (wich was really hard) I`m happy. God I was soo blind b4. I`m healthy now and I`m planning to have a child with my partner and is really imprtant for me to give a good example to my child. I don`t want him to think that be overweigh is ok. I would like to thanks the persnon that invent xenical. Good luck with your weigh loss to all of you. Melissa F 26 3 weeks

 5  To help me loose weight The only sideeffects I have experienced are the ones I have asked for by eating too much fatty foods which causes the horrible orange diarreah. I started off with "Alli" which in Norway has half the amount of orlistat in it. It worked fine so I asked my doctor for a prescription on Xenical.(Which has twice the amount of orlistad and half the prize) I have no sideeffects of the pill unless I eat too much fatty food. The pill helps me get consious about what I put in my mouth, and together it has made me loose 1 kg every week so far. I have tried every diet available before this without effect, but this pill har really helped med loose weight and made me more consious about my intake of food. F 46 2 months

I am really determined to lose the weight and this pill has been a great aid in doing so. Yes, I have the oily stool but you take the bitter with the sweet you know?~~~ I say to anyone who is serious about losing weight, this is a wonderful companion to your dedication and willpower because the pill wont work a miracle on it's own, you have got to change your habits.

 5  very overweight. Very windy, urgent need to use toilet. I was prescribed these tablets by my GP last week, as I told him I find it very hard to lose weight on my own, I tend to binge eat regularly. Also,as a big help, they are free on prescription if you live in Wales, UK, as all prescribed medication is now. I also joined WW on the same day as I started them, so it gives me more motivation not to eat a high fat diet. I don't think the side effects would bother me too much, it's a small price to pay for the outcome. F 39 6 days
