Orlistat vs Xenical: Making Your Purchase Decision
Generic Orlistat vs Branded Xenical: The Facts
When comparing orlistat 120mg with Xenical 120mg, you're looking at clinically equivalent medicines. Both contain exactly 120mg of orlistat per capsule and work identically - blocking approximately one third of dietary fat absorption in your gut. The primary difference lies in cost and manufacturer. Generic orlistat 84 capsules cost £32.99 (£29.69 with EDM10), whilst branded Xenical costs £42.99 (£38.69 with EDM10). That's a saving of £9 per month choosing generic orlistat.
Which Should You Buy?
For most patients, generic orlistat 120mg offers exceptional value without compromising clinical effectiveness. Both products require the same prescription process, following online clinical assessment by UK-licensed prescribers. Both are dispensed by our GPhC-registered pharmacy with identical next day delivery service. If you prefer branded medicines or have previously used Xenical successfully, the branded option remains available. However, the active ingredient, dose, and expected effects are identical between products.
Pricing Comparison Across All Pack Sizes
Generic orlistat pricing: 42 capsules £15.20, 84 capsules £29.69, 168 capsules £57.59, 252 capsules £86.39 (all with EDM10). Xenical pricing: 42 capsules £19.35, 84 capsules £38.69, 168 capsules £78.29, 252 capsules £116.09 (all with EDM10). Longer treatment courses offer better value per capsule. The 84-capsule pack provides four weeks of treatment at three capsules daily with main meals containing fat.
Alternative: Alli 60mg
Consider Alli 60mg as a lower-strength alternative. At half the dose of prescription orlistat, Alli may suit those preferring gentler introduction to fat-blocking treatment. Alli 84 capsules cost £49.49 with EDM10, providing eight weeks of treatment. However, the lower dose blocks a smaller proportion of dietary fat compared to prescription-strength products.
How Both Products Work
Whether you choose generic orlistat or branded Xenical, the mechanism remains identical. Both inhibit lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed. Unabsorbed fat passes naturally through your body. Both work best alongside a reduced-calorie, lower-fat diet with no more than 15g fat per meal. This dietary approach minimises gastrointestinal side effects whilst maximising effectiveness.
