Which Should You Choose: Orlistat or Xenical?

How Many Calories Does Orlistat Block vs Xenical?

Both Orlistat 120mg and Xenical 120mg block exactly the same number of calories - approximately one third of dietary fat from each meal. This translates to roughly 5g of fat blocked per 15g consumed. The active ingredient is identical (orlistat), so the calorie-blocking effect is clinically equivalent regardless of which you choose.

Price Comparison: Orlistat vs Xenical

Generic Orlistat offers substantial savings over branded Xenical. For a 4-week supply, Orlistat costs £29.69 with EDM10 versus Xenical at £38.69 - saving you £9 monthly. Over 12 weeks, choose Orlistat for £86.39 or Xenical for £116.09. Both require the same prescription process and provide identical clinical effects.

Why Choose Generic Orlistat?

Orlistat 120mg delivers the same fat-blocking mechanism as Xenical at a lower cost. Many patients prefer the generic option for ongoing treatment, especially for longer courses. Starting from £15.20 for 2 weeks with EDM10, it's the most economical choice for weight management support alongside your reduced-calorie, lower-fat diet.

Why Some Patients Choose Xenical

Some patients prefer the branded Xenical option despite the higher cost. Made by Roche, Xenical has brand recognition and identical packaging consistency. However, the clinical effect remains the same as generic Orlistat - both block approximately one third of dietary fat when taken with meals.

Alli 60mg: The Lower-Strength Alternative

Alli contains half the dose at 60mg per capsule. While blocking fewer fat calories than the 120mg prescription options, it may cause milder gastrointestinal side effects. Alli costs £26.09 for 4 weeks with EDM10. A prescriber can advise which strength suits your individual needs.
