Buy Xenical (orlistat) online

Xenical is a prescription strength weight loss aid which contains a lipase inhibitor called Orlistat. When taken alongside a low-fat, reduced calorie diet, it is possible to lose 5% or more of your body mass within a year.

It's important to note that Xenical is most effective when taken alongside a healthy, balanced diet. Taking Xenical (orlistat) on its own, without a diet and exercise plan, is unlikely to produce desirable results and may increase your risk of side effects.

Our confidential service makes it easy for you to get the weight loss treatment you need delivered straight to your door. If your order is approved before 3pm, Monday to Friday, our UK pharmacy will dispatch your item the same day, intended for a next-day delivery.

Any changes to diet and exercise when taking Xenical should be continued after treatment.

Xenical weight loss capsules contain 120 mg of orlistat and are available in packs or bottles of 21, 42, and 84 doses. Orlistat is also available as a generic weight loss supplement and contains 120mg of Orlistat.

Orlistat is also available as the brandnames Alli and Orlos.

How does Xenical (orlistat) work?

Orlistat, the active ingredient of Xenical weight loss pills, works by suppressing enzymes in the gut called lipase, which process the fat you consume in your diet. By stopping these enzymes, it is estimated that a third of the fat you consume passes through the body without affecting your weight while taking Xenical.

While taking Xenical you should avoid fatty foods, such as sweet treats and savoury snacks, and ingest more fruits and vegetables. For an adult eating a 2000kcal diet, it is recommended to consume less than 67g of fat per day while taking Xenical (orlistat).

Consuming fatty foods while taking Xenical (orlistat) may result in steatorrhoea - a condition similar to diarrhoea which causes loose and oily stools.

How do I take Xenical (orlistat)?

Always take medicines as prescribed by your doctor.

The typical dose of Xenical (orlistat) is one 120 mg tablet immediately before, during or within an hour after one of the three main meals a day - breakfast, lunch and dinner.

If a meal is skipped, or contains no fat, there is no need to take Xenical (orlistat).

Taking more Xenical (Orlistat) weight loss pills before a meal will not make you lose weight faster but may increase your risk of side effects.

Xenical (orlistat) should be taken alongside a healthy and balanced diet. You should speak to your doctor about finding a suitable diet and exercise plan which is safe for you.

Weight loss tips

Weight loss requires more than just taking pills. It takes commitment to a diet and exercise regime, which should be continued even when you stop taking Xenical. You will most likely need to make changes to your eating habits and learn how to control portion sizes. If you are unsure about what kind of diet or exercise plan is suitable for you, speak to your doctor.

It may make your weight loss journey easier if you get your family or friends to support you. It can also give other people you live with the opportunity to learn a thing or two about healthy eating.

For some, just the thought of exercise can be difficult. For others, their busy lifestyle can make it challenging fitting in a rigorous workout routine. But there are a number of small exercises you can do which can have great results. Instead of standing around and waiting for the kettle to boil, do some lunges or squats to give your legs a light workout. There are plenty of other ways you can fit in small exercises to your daily schedule.

A fitness tracker, such as a FitBit, can help you track your exercise. They link up to your phone and show you how much exercise you do on a day-to-day basis.

Keeping a food diary to document your weight loss journey can be used to identify your eating habits, keep a track of your weight changes, and note down changes you should consider. Keep a note somewhere, such as on your phone, of what you eat after each meal. Note down how many calories and the amount of fat in the meal you ate.

Frequently asked questions

What should I do if I forget to take Xenical?

If you forget to take Xenical when you should, take it as soon as you remember and continue to take it as you regularly would. Do not take more Xenical to make up for the missed dose.

What should I do if I take more Xenical (orlistat) than I should?

If you accidentally take more Xenical weight loss pills than prescribed, speak to your doctor as soon as possible.

What results can I expect from taking Xenical?

If you take Xenical weight loss pills alongside a controlled diet and exercise routine, you can expect to lose 5% of your body weight within the first 12 weeks.

We have prescription medication that works alongside your own efforts to maximise your weight loss and to give you the break you need in the quest for a slimmer figure.

If I take Xenical (orlistat), does it mean I don't have to exercise?

Xenical weight loss pills should be taken alongside a healthy lifestyle, which includes a sufficient amount of activity.
