What is Xenical

Xenical is a prescription medication specifically designed for weight loss and maintaining a healthy weight. Here’s what you need to know:

Active ingredient

Xenical contains Orlistat, which acts directly in the digestive system to block fat absorption.

How it works

Xenical inhibits enzymes responsible for fat breakdown, helping you to reduce your calorie absorption from meals.


Xenical is taken three times a day, aligned with main meals that contain fats.


Xenical is ideal for adults with a BMI of 30 or more, or 28 or more with comorbidities like type 2 diabetes.


Clinical studies show Xenical can lead to significant weight loss — about 5-10% of body weight over 6 to 12 months.

Side effects

Potential side effects include increased frequency and urgency of bowel movements, farting more often, oily or fatty stools, and oily discharge from your rectum.
Xenical is a proven solution for effective weight control when combined with a balanced, calorie-controlled diet.

Missed dose

If you miss a meal or have a meal without fat, skip the Xenical dose for that meal.

Supporting your mental health

Obesity, being overweight mental health problems, such as depression and eating disorders, can negatively affect each other, making it harder to manage your weight. It’s important to recognise the link between your mental health and your weight so you can seek help if you need it.

Talking therapies

Cognitive Behavioral Therapy (CBT) can be effective for tackling the psychological challenges associated with eating disorders and obesity. It focuses on changing the way you think and behave, helping to break the cycle of negative thoughts and actions that can impact eating habits and body image.

To find a CBT therapist via the NHS, you can refer yourself or speak to your GP, who can refer you to talking therapies in London.

Why it’s important

By addressing mental health alongside physical health, you have a much better chance of succeeding with Xenical, improving your overall wellbeing and quality of life. If you find yourself in need of urgent mental health support, contact your local mental health helpline provided by the NHS. These resources can provide immediate care and support in times of need, ensuring that no one has to face their challenges alone.

Keeping active

Exercise doesn’t just burn calories. By triggering the release of endorphins, the body’s natural mood enhancers, exercise has been shown to help combat depression and anxiety.

There’s plenty of ways to stay active in London, from local gyms and fitness classes to parks and recreational facilities.

Support in London

In London, Central and North West London NHS Foundation Trust provides comprehensive mental health support for Xenical patients. They can help with eating disorders and weight-related mental health issues.

Discuss your mental health with your GP in London who can refer you to a specialist. You may also be able to refer yourself directly without a referral, but you will need to be registered with a GP to get talking therapies on the NHS. You can find a GP in London on the NHS website.
