What is Xenical and what does it do?

Xenical is a medicine used to help obese patients lose weight. It contains 120mg of the active ingredient orlistat and may be prescribed to patients with a BMI above 30.

Xenical works by binding to enzymes in the digestive system called lipases. Lipases break down fats from your food so that it can be absorbed in the intestines. When this effect is hindered, the fat from your food will pass through the intestines instead of being absorbed.

When is Xenical prescribed?

Xenical capsules are indicated for use in patients with a BMI above 30. They may also be prescribed to patients with a BMI above 28 if there are associated risk factors present, such as type 2 diabetes.

What does BMI mean and how do I measure my BMI?

BMI is short for Body Mass Index. It is a chart used to help yourself and health professionals understand your healthy weight range based on your height. WHO, the World Health Organisation, considers a BMI of between 18.5 and 25 represent a healthy weight. A BMI of 30 or above is considered obese.

Not sure of your BMI? Use the NHS BMI calculator here (link opens in new tab).

Is Xenical suitable for my condition?

Xenical may be prescribed by our doctors if you are obese and have a BMI of 30 or above. There are however some medicines and health conditions that may affect the suitability of Xenical.

Xenical is not suitable if any of the below applies to you:

  • If you are allergic or sensitive to orlistat of any of the other ingredients in the patient information leaflet.
  • If you suffer from chronic malabsorption syndrome.
  • If you have cholestasis.
  • If you are breast feeding.
  • If you are taking ciclosporin.
  • If you are taking acarbose (to treat type 2 diabetes mellitus).

Always let our doctors know if you are taking any other medicines by including this information in the medical questionnaire.

What is the recommended dosage of Xenical?

You should follow the doctor’s instructions on how to take this treatment. The doses outlined below is for your reference only. Swallow the Xenical capsules whole with a glass of water, immediately before, during or after a meal.

Xenical dosage for Weight Loss

Note, Xenical should only be taken if your meal contains fat. If your food does not contain fat, do not take Xenical.

Does Xenical cause any side effects?

Yes, just like all medicines, Xenical may cause side effect in some users. Most side effects caused by Xenical affect your digestive system and are more likely to occur during the beginning of the treatment.

Can I reduce the risk of getting side effects?

Yes, you can reduce the risk of side effects by letting our doctors know of any other medication you may take as well as any other medical condition you may have. Please include this information when you fill in the medical questionnaire.

You can also reduce the risk of side effects by following a balanced and nutritious diet. For best results, you should follow a controlled calorie diet plan while taking Xenical.
