Which Should You Choose: Generic or Branded?
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 blocking approximately one third of dietary fat absorption in your digestive system. The primary difference lies in cost and manufacturer preference.
Generic orlistat 120mg costs £32.99 for a 4-week supply (£29.69 with EDM10), whilst branded Xenical costs £42.99 for the same period (£38.69 with EDM10). This represents monthly savings of approximately £9 when choosing generic orlistat.
Kidney Function Considerations
During your online clinical assessment, our UK-licensed prescribers evaluate kidney function alongside other health factors. Orlistat may increase oxalate absorption, potentially affecting patients with kidney stone history. Both generic orlistat and Xenical require the same kidney function considerations - the assessment process remains identical regardless of your choice.
Your prescriber will review your medical history, current medications, and kidney health before determining treatment suitability. This comprehensive assessment ensures safe prescribing whether you choose generic or branded options.
Clinical Equivalence, Price Difference
Orlistat and Xenical deliver identical clinical outcomes when used alongside a reduced-calorie, lower-fat diet. Both inhibit lipase enzymes in your gut, preventing approximately one third of dietary fat absorption. The unabsorbed fat passes naturally through your body.
Many patients choose generic orlistat for value, whilst others prefer branded Xenical. Your prescriber can help determine which option suits your preferences and budget during consultation.
Alternative Option: Alli 60mg
For those preferring lower-strength treatment, Alli 60mg provides half the dose of prescription orlistat. At £28.99 for 4 weeks (£26.09 with EDM10), Alli offers a gentler introduction to orlistat therapy with typically milder gastrointestinal effects.
