Xenical Review

xenicalOne of the most popular prescription diet pills right now is Xenical. Besides aggressive advertising, what has made Xenical so popular is its effectiveness.

People turn to this product when they’ve lost a lot of weight and need a strong solution that keeps that weight from coming back.

On the plus side, Xenical does work. On the down side, it may cause serious side effects that aren’t a concern when you use a natural diet pill like Stimuretix.

What Is Xenical?

Xenical is the brand name for an ingredient called orlistat, which is also the main ingredient in the Alli diet pill. Orlistat is classified as a lipase inhibitor, which means that it prevents fat from being absorbed by the body.

What Is the Benefit of Xenical?

A diet that is high in simple carbs, unhealthy fat, or calories introduces a large amount of fat into your body. Because it prevents fat from being absorbed, Xenical can prevent weight gain. It may also help you lose body fat; however, Xenical is designed to be used by people who’ve already lost a significant amount of weight and want to prevent it from coming back.

How to Use It

Xenical comes in capsule form and it is supposed to be taken with every meal that contains fat, or in other words, 3x a day. You’ll get the best results from this diet pill if you take it during the meal or up to an hour after the meal.

Because this is a prescription product, it is very important that you use it as directed by your doctor. Don’t take more than the recommended amount and don’t take it for longer than you are supposed to.

What Are the Concerns?

As is the case with every prescription diet pill on the market, Xenical has a list of side effects that tag along with it. If you have these symptoms and they are severe or don’t go away, you should inform your doctor:

• Gas with oily spotting
• Loose stools
• Difficulty controlling bowel movements
• Stomach pain
• Headache

These symptoms are very serious and you need to call your doctor immediately if you experience them:

• Difficult breathing or swallowing
• Nausea
• Vomiting
• Loss of appetite
• Yellowing of the skin or eyes

Final Thoughts

Xenical is very effective, there’s no doubt about that, but it may not be worth trying because of the high-risk of nasty side effects. The most common side effect reported by users is loss of control over bowel movements. In fact, many people say that they have to carry an extra change of clothes around, just in case.

If you want a diet pill that prevents fat absorption, I recommend that you try Stimuretix. It contains Razberi-K and ThermoDiamine, which have both been proven to prevent the body from storing fat. These and all the other ingredients in Stimuretix are natural, so side effects are rarely reported by users. Stimuretix is more affordable than Xenical; it’s easier to obtain (you don’t need a prescription); and it comes guaranteed, so you can try it risk free.

    I’ve been taking Xenical for one month now and the only thing I’ve seen is the oily discharge and uncontrollable gas not to mention gas pains in my side.
    First I thought that was good if the oil is running out so is the fat. My diet is not overly fatty so I figured these pills would work on the fat already stored in my body. WRONG they work on stopping the fat coming in. Would NOT recommend this product at a price od $183.00 per month in Canada. I got better results from cheaper fat blockers.

    sorry cant agree with you all.i have underactive thyroid and have struggled for 4 years to lose weight .I went to my doctore five months ago and was subscribed xenical….i have lost 20lbs.I know it has been a slow process but after every diet going and no weight loss to me its such a positive!If you follow a low fat diet then you wont get those side effects ..there is no such thing as a miracle diet pill but to me they come close to being one!!!!

    hi, if you use xenical properly they work and you do not experience any off the side affects. If you ring the no on the boxs, if you get them off your gp they will mapp your progress and send you booklets with recipes in and they also explain how much fat you should be eating, in the recipe book they show you how much fat is in the meal so it gives you some idea. It is no good just buying them from anywhere as you need to know how to use them

    Well, 2 years ago I started on xenical and in 4 months I had lost 2 stone!! BRILLIANT!! However…I will most definitely back the claims about gas, unpredictable and VERY messy bowell movements! The ‘fallout’ is without doubt DISGUSTING especially if you dont get to the bathroom in time! And it stinks!! Nothing ladylike about this pill AT ALL. I didnt work when I was taking these pills. I was a stay at home mum so it was ok to run the risk of accidents which did happen regularly. If you work, these will NOT be for you because you simply cant predict when or where youre gonna be caught short…and this WILL happen!! So…if you can handle all of that then I say go for it. It worked for me with no other side effects.

This has worked for my mom she was on them for about 5 months and lost 1st 7lbs and has now come off them and has managed to keep the weight off!! i would NEVER try these again, very embarassing when your out in public and need to go to the loo, the colour of your stools stain the loo….lol…sorry to sound crude but really is bad,and you can see fat floating about the toilet even when you have a wee!! really hard to contol your bowel movement!

    I have been using xenical for over a year now and love it. My weight has dropped from 24.5 stone to 20, slow and steady but its the first time i have lost weight and not put it all back on again and more. My bowel habits have changed, but thankfully, for the better. To be honest, if i was more active, i would loose weight quicker. Can take it just before, with,or just after meal, it doesnt seem to make a difference.

    I’ve been on Xenical for a couple of years on and off and it does have good results! I’ve got to come off it my GP tells me but I’ve stored up 3 boxes so I’ll be able to take one a day until I can go back on it—Going for Lipo examination in 2 days so may not need it—the wind is good fun if you let one go queitly after someone has ‘parped’ loudly in our local social club then they get all the blame—have to watch no follow through though.

    Hi, I think a lot of you are really just not eating right whilst taking Xenical – you are NOT SUPPOSED to be having pizzas and heavy cheeses or saturated fat – you can have Salmon which has good fat and you just have to realise by erring that you will suffer the consequences for eating STUPIDLY…….I follow a really healthy mediterrean diet as I live in Spain and so I have couscus which I make myself and add a little olive oil which is healthy..I have lost a quite a few kilos and better than that I am now wearing size 46 trousers instead of horrible size 20 ones -I am 1.67 in height and a shop assistant asked me if I was a size 44 and I said , “erm, no – actually a 46 but I’m getting there!!” I was SOOOOOOOOOO pleased because I just hated going into shops and some thoughtless assistant saying, “We don’t have anything in your size sorry” – it was soooooo disheartening but now I’m more active and use my static bike and even do some hill-climbing occasionally…..everyone remarks on how I look younger etc… and now I feel happier, ok sometimes there is a rush to the loo but I wear slimline panty liners and only once did i have some oily spotting, ok admittedly when I go to the loo there is quite an explosion but now I’m used to it and I know that it’s therefore working as I drink semi-skimmed milk and eat low-fat cheeses but they do contain some fat!!! Just don’t take them if you’re going out on special occasion – I can’t eat as much as before – my appetite has altered and I eat smaller portions of food.
    I think Xenical gave me a new lease of life and I feel healthier and younger…….(I am 50 something!!!).
    So POO to all you losers who are poo-pooing xenical so easily – you deserve to soil yourselves if you don’t know how to eat more sensibly……….
    All the best to those are perceveering and don’t let the cynical ones or unfortunate ones get you down – I just spray OUST in the loo or put on the air-conditioner, most loos have them fortunately…
    I’m not trying to get thin just to feel good in a smaller size of clothes and THANK YOU XENICAL MAKERS , YOU SURE DID A GOOD JOB WHEN YOU THOUGHT THIS ONE UP!!!
    OH, AND ALWAYS TRY AND DRINK A LOT OF WATER IT HELPS!

    Am thinking of going on Xenical.
    I go to my doctors all the time and they say “what do you want me to do about it?”
    I tried dieting and exercising, plus am fitter than some skinny people!
    But the weight comes off slow. so now I am looking at the net reading up on good pills….
    reading both good and bad comments….
    I am going to look in it somemore… feeling,looking good is a killer… you need to work hard at it! but like people like me we need help to help ourselves.

    hi everyone, have been taking xenical for the past twelve months, (had a ahort break from them inbetween).I found them to be alright. No nasty discharge. in the begining one or two nasty smelling gas releases, apart from that ok. All i can suggest is you take a serious look at what you are eating,cause it only tries to get rid of the excessive fats you eat, you do have to try and eat sensible. It is obvious that if you eat lots of pizza, fatty foods and chocolate, these tablets will give you nasty side effects, there are trying to help you and your body get rid of excessive fats and unneed things in your system. JUST TRY AND STICK WITH IT SENSIBLY AND YOU WILL FIND YOU WILL BE ALRIGHT. hope you all lose the weight with no side effects.

Gone from size 10 to 18! – Am having about 20-25gramsof fat a day and have only had 2 bowel movements and abit of smelly wind!

    i have been taking xenical for few years now, everytime i loose some weight i just start it again, and believe me it really works specially if u do some exercise with it,it remooves a part of your intake fat, and when i read the reviews about people having problems with bowel moovement i get surprised because it is all related to what you eat it seems that theeses people were eating too much fat and of course they will have problems coz the pill is doing it s job wich is remooving the fat! as for the spasm you may have some and some gases too but nothing too much, they are all worth the fat that is getting out of ur body. This pills works definitelly try it and don’t get shocked when u see the fat coming out, and don t put it on the pill, remember this is what u ate last night so try to eat healthier. Eve

    I’ve been taking xenical for 7 months and i lost over 40 kilos, no complaints, just had to go to the loo everyday at exactly the right time, but no gas oil at all. but the secret is to exercice two hours after u take it, and u should take the pill in the middle of ur meal , so that it could be 100% effective, if u do that, there won’t be no sideeffects.

    xenical does work but yes can be messy, only downfall in the uk is Doctors put you on it, you lose weight but not the target they give you, but although it works and you are losing weight but not as quick as they want you to, they take you off it. Then you get fat again without the help.

    After stopping smoking 2 1/2 years ago, my weight has increased slowly by 4 stone, i’ve tried every diet going and only lost 1-2lb in a month, Xenical was my last hope, i started doing a wheatfree regime at the same time and have lost 1st in one calendar month and i’m over the moon, so i recommend Xenical, i have not suffered any of the nasty sided effect’s i’ve read about and am hoping that i can get rid of the other 3st without any problems too.

    To: Victoria Hammond: Your comment that if you don’t eat fat you will not get the nasty side effects.

    Isn’t that what Xenical is used for, to block the fat?

    In other words if you are not eating fat then you DON’T take Xenical.

    Plus, one does not need a prescription for Xenical in Pennsylvania. It is over the counter.

    P.S. Oh and the side effects are to say the least stinky ! What comes out of the other end is a foul smelling like diarheaa smelling oil. You must wash your clothes several times to get the stinky smell out of your clothes.
