Which Should You Buy: Generic Orlistat or Branded Xenical?
How Quickly Do Both Orlistat and Xenical Work?
Both orlistat 120mg and Xenical 120mg work identically from your first dose. They begin blocking approximately one third of dietary fat absorption within the digestive system as soon as you take them with a meal. The lipase inhibitor mechanism acts locally in the gut, preventing fat absorption immediately. Neither requires a "build-up period" — the effect starts with your first capsule taken alongside a reduced-calorie, lower-fat diet.
Orlistat vs Xenical: The Key Differences
Generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose. Clinical effectiveness is equivalent between both options. The primary difference is cost: orlistat 84 capsules (4-week supply) costs £32.99 (£29.69 with EDM10), whilst Xenical 84 capsules cost £42.99 (£38.69 with EDM10). This represents potential savings of £108 annually by choosing generic orlistat over branded Xenical.
Pricing Comparison: Orlistat vs Xenical
Generic orlistat offers significant savings: 42 capsules from £15.20, 84 capsules from £29.69, 168 capsules from £57.59, and 252 capsules from £86.39 (all with code EDM10). Xenical pricing: 42 capsules from £19.35, 84 capsules from £38.69, 168 capsules from £78.29, and 252 capsules from £116.09 (with EDM10). Both require prescription following online clinical assessment by UK-licensed prescribers.
Alli 60mg: The Lower-Strength Alternative
Alli 60mg contains half the orlistat dose of prescription-strength options. At 42 capsules for £26.09 (with EDM10), it offers a lower-strength starting point. However, prescription-strength orlistat 120mg or Xenical 120mg may be more clinically effective for eligible adults with BMI 30+ or BMI 28+ with weight-related health conditions.
How to Choose Between Orlistat and Xenical
Both options work identically, taken three times daily with main meals containing fat. Generic orlistat provides the same clinical benefit at lower cost — ideal for budget-conscious patients. Some prefer branded Xenical for familiarity with the manufacturer. Your prescriber can discuss both options during online consultation. Both are dispensed by our GPhC-registered pharmacy with next day delivery across the UK.
