Xenical vs Orlistat: Same Medicine, Different Prices
When comparing Xenical and orlistat 120mg capsules, both contain identical active ingredients at the same dose. Clinically, they work in exactly the same way - blocking approximately one third of dietary fat absorption. The key difference lies in cost. Generic orlistat 120mg provides the same clinical effect as branded Xenical at a significantly lower price point.
2-Week Supply: Ideal for Starting Treatment
Perfect for first-time users wanting to assess tolerance. Orlistat 120mg (42 capsules) costs £16.89 (£15.20 with EDM10), whilst Xenical 120mg costs £21.50 (£19.35 with EDM10). This shorter supply allows you to evaluate how the medication works alongside your reduced-calorie, lower-fat diet before committing to longer treatment periods.
4-Week Supply: Most Popular Choice
The 84-capsule pack provides one month's treatment. Orlistat costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). This represents savings of £9.30 monthly by choosing generic orlistat. Four weeks allows sufficient time to establish routine and see initial weight management support effects when combined with dietary changes.
8-Week Supply: Enhanced Value
Two months' treatment with 168 capsules offers better value per capsule. Orlistat costs £63.99 (£57.59 with EDM10) versus Xenical at £86.99 (£78.29 with EDM10). Choosing orlistat saves £20.70 over eight weeks. This duration suits patients established on treatment who want to reduce ordering frequency whilst maximising savings.
12-Week Supply: Maximum Savings
The 252-capsule pack provides three months' treatment with the best cost per capsule. Orlistat costs £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10). Generic orlistat saves £29.70 over 12 weeks. This option provides excellent value for patients committed to longer-term weight management support.
Lower-Strength Option: Alli 60mg
Alli contains half the dose of prescription orlistat at 60mg. Available in 4-week (£28.99/£26.09 with EDM10), 8-week (£54.99/£49.49 with EDM10), and 12-week supplies (£129.99/£116.99 with EDM10). This option may be suitable for those preferring a gentler starting approach, though clinical potency is reduced compared to 120mg formulations.
How to Choose Your Pack Size
Consider your treatment goals and budget. New users often start with 2-4 week supplies to assess tolerance and effectiveness. Established users typically choose 8-12 week packs for better value and convenience. All options require prescription following clinical assessment by our UK-licensed prescribers. Treatment works best alongside a reduced-calorie, lower-fat diet and regular physical activity.
