Information on Xenical

Xenical is the branded version of Orlistat which works by blocking one third of the fat in your diet from being absorbed by your body. Rather than being absorbed, it’s excreted through your stool (poo).

Clinicians will only prescribe Xenical to those with a BMI of 30 or over. In some cases, if you have a chronic condition such as diabetes that may improve with weight loss, then Xenical may be prescribed to those with a BMI of 28.

Xenical is not suitable for anyone with a BMI of under 28.

How to take Xenical for the best results

Xenical is effective when combined with a healthy diet and exercise. If you take Xenical but are still eating a high fat diet, then the medicine will only be able to bind to one third of the fat and therefore no meaningful weight loss will occur.

Some tips for cutting out fat in your diet include:

  • Low fat cooking sauces
  • Lean white meat rather than fatty red meat
  • Margarine instead of butter

Follow our advice pages for more information on how to incorporate healthy eating and exercise into your daily life.

Alternatives to Xenical

Nothing can replace a healthy diet and exercise when it comes to weight loss, but there are other options to help your weightloss journey. For example, alli is available over the counter at LloydsPharmacy which is half the strength of Xenical and does not require a prescription.

LloydsPharmacy are also now offering an exciting new medicated weight loss service, which you can find out more about here.

Can you buy Xenical over the counter?

No, Xenical can only be purchased with a prescription after a consultation with a qualified clinician. Your height and weight will also need to be measured in pharmacy upon collection for your own safety. Never attempt to buy Xenical online from a website that does not require a consultation with a registered clinician.
