Which Should You Buy: Orlistat or Xenical?
Orlistat vs Xenical: The Key Facts
Both orlistat 120mg and Xenical 120mg contain identical active ingredients at the same dose. The clinical effect is equivalent - both work by inhibiting lipase enzymes in your gut to block approximately one third of dietary fat absorption. The primary difference lies in cost and branding.
Generic orlistat costs £32.99 for 84 capsules (4-week supply), reduced to £29.69 with code EDM10. Branded Xenical costs £42.99 for the same supply, reduced to £38.69 with EDM10. This represents monthly savings of £9 when choosing generic orlistat.
Clinical Equivalence Explained
Whether you choose orlistat or Xenical, you receive the same weight management support. Both medications work locally in your digestive system, preventing absorption of approximately one third of the fat you eat. Unabsorbed fat passes naturally through your body, reducing calorie intake from dietary sources.
Following clinical assessment by UK-licensed prescribers, both options may be prescribed for adults with BMI 30+ or BMI 28+ with weight-related health conditions. Treatment must always be combined with a reduced-calorie, lower-fat diet and increased physical activity.
Cost Comparison Across All Pack Sizes
Generic orlistat pricing with EDM10: 2 weeks £15.20, 4 weeks £29.69, 8 weeks £57.59, 12 weeks £86.39. Xenical pricing with EDM10: 2 weeks £19.35, 4 weeks £38.69, 8 weeks £78.29, 12 weeks £116.09. Longer treatment courses show greater savings with generic orlistat.
Alternative Option: Alli 60mg
Alli provides half the dose at 60mg orlistat per capsule. While clinically less potent than prescription-strength options, Alli may suit those preferring a lower-strength starting point. Available in 84 capsules (8 weeks) for £49.49 with EDM10.
