Question 1

What is Xenical and how does it work?

Accepted Answer

Xenical contains Orlistat 120mg, a lipase inhibitor that works by blocking the absorption of about one-third of dietary fat. It is taken three times daily with meals. Unlike GLP-1 medications, Xenical does not affect appetite — it works purely by reducing fat absorption in the gut.

Question 2

Is Xenical the same as Alli?

Accepted Answer

Xenical and Alli both contain Orlistat, but at different strengths. Xenical is 120mg and requires a prescription. Alli is 60mg and is available over the counter without a prescription. Xenical is approximately twice as strong as Alli.

Question 3

Do I need a prescription for Xenical?

Accepted Answer

Yes. Xenical (Orlistat 120mg) is prescription-only in the UK. You will need a clinical consultation before a pharmacy can dispense it. If you prefer an over-the-counter option, Alli (Orlistat 60mg) does not require a prescription.

Question 4

What are the side effects of Xenical?

Accepted Answer

Common side effects include oily or fatty stools, increased bowel movements, flatulence, and stomach pain — particularly if you eat high-fat meals. These effects are reduced by following a lower-fat diet. Xenical should be taken alongside a calorie-controlled, lower-fat diet for best results.

Question 5

Is Xenical cheaper than Mounjaro or Wegovy?

Accepted Answer

Yes, Xenical is significantly cheaper than GLP-1 injectable medications. However, it works differently and typically produces less weight loss. It is suitable for patients who cannot take or prefer not to use injectable treatments. Compare current prices from all verified providers on Treatcompare.
