Which Should You Choose: Generic Orlistat or Xenical?
How Much Fat Does Xenical Block vs Generic Orlistat?
Both Xenical 120mg and generic orlistat 120mg block exactly the same amount of dietary fat - approximately one third. They contain identical active ingredients (orlistat) at the same dose, so the fat-blocking effect is clinically equivalent. Whether you choose branded Xenical or generic orlistat, you'll get the same mechanism of action: lipase enzymes in your gut are inhibited, preventing roughly one third of the fat you eat from being absorbed into your body.
Key Differences: Price vs Performance
The clinical effect is identical, but the price difference is significant. Generic orlistat costs £32.99 for a 4-week supply (£29.69 with EDM10), whilst Xenical costs £42.99 (£38.69 with EDM10). Over 12 weeks, you'll save approximately £27 by choosing generic orlistat at £86.39 versus Xenical at £116.09. Both require a prescription following clinical assessment by our UK-licensed prescribers.
Alli 60mg: The Lower-Strength Alternative
Alli contains half the dose at 60mg per capsule, blocking a smaller proportion of dietary fat compared to the 120mg prescription versions. At £49.49 for an 8-week supply (with EDM10), Alli may suit those preferring a gentler starting point, though it's clinically less potent than prescription-strength orlistat or Xenical.
Side Effects: Identical Across Both Options
Since both products contain the same active ingredient at the same dose, side effects are identical. Most side effects are gastrointestinal and directly related to dietary fat intake. Keep meals to approximately 15g fat each to minimise oily stools, spotting, and urgent bowel movements. These effects indicate the medicine is working by preventing fat absorption.
