Xenical is a brand name that people commonly use to refer to the drug Orlistat, which is available both as a prescription and an over-the-counter drug, aimed at helping the user to lose weight. It is a product specifically made for overweight individuals as a supplementary drug. The application is emphasized in persons with obesity co-morbidities like diabetes, hypertension, hyperlipidemia, and ischemic heart disease. In the UK, France, and Spain, Xenical is known as a popular choice for those who want help from a doctor to manage their weight.

Xenical comes in 120 mg capsules. An over-the-counter lower-dose version which contains 60 mg of Orlistat is available. Both of these operate on the same concept of fat-blocking. The standard prescription for the 120 mg strength is one capsule taken with each main meal containing fat, not more than three times a day. Moreover, in Belgium, Croatia, Denmark, and Poland, the anti-obesity drug Xenical is considered a reliable member of the therapy plan of excess weight. Doctors in these areas keep on explaining the importance of the drug as a treatment method which gives the best outcome when used together with the changes in lifestyle.
