Orlistat (also known under the brand name Xenical), is a prescription medicine which is licensed to treat obesity. It is currently the only approved medicine available on prescription in the UK for weight loss. It works by stopping your body from absorbing the fat from food which can help you to lose weight more easily. The fat is then excreted through the stools. Orlistat is NOT an appetite suppressant.
Orlistat is taken three times a day during or up to an hour after each meal. It must be taken with a meal that contains no more than about 30% of calories from fat.
If you forget to take the medicine, take it as soon as you remember but only within one hour of eating a meal. Do not take a double dose.
When you first start taking Orlistat your target weight loss after 3 months is to lose 5% of your body weight. If you are able to do this, then it means that Orlistat is working for you and you can continue to take it to lose more weight. Orlistat can be prescribed for weight loss for up to 2 years. Once your body mass index falls below 28, you must discontinue use of Orlistat.
It is advisable to take a multivitamin supplement as Orlistat can also reduce the absorption of fat soluble vitamins. The vitamin can be taken once a day at least two hours before or after taking Orlistat.
Side effects can include:
Note that side effects such as changes in bowel habits can be more frequent if Orlistat is taken with a diet high in fat. No more 30% of calories with each meal should come from fat.
Also note that if excessive diarrhoea is present then additional contraceptive precautions may need to be taken in those patients taking the contraceptive pill.

Obesity is a term used to refer to people who have a high degree of body fat.
It is measured using a scale called body mass index (BMI) which is your weight in kg divided by your height in m2.
BMI below 18
BMI 18-25= normal
BMI 25- 29= overweight
BMI 30-40= obese
BMI more than 40= very obese
Body mass index can be calculated by taking your weight in kg and dividing it by your height in m2. Orlistat is intended for use in patient’s whose body mass index is greater than 30 or else greater than 28 with other associated risk factors (e.g. diabetes).
It is expected that you will lose a minimum of 5% of your body weight after 12 weeks of treatment with Orlistat. If you don’t lose any weight in the first 3 months of treatment, then you will not be able to continue treatment as the medicine has not worked for you. You can try again after 6 months break and see if the medicine has any further effect.
You can continue to take Orlistat for up to two years or until your body mass index reaches 28.
