Which Should You Buy: Generic or Branded Orlistat?
Orlistat vs Xenical: Identical Ingredients, Different Prices
When comparing orlistat ingredients in the UK, both generic Orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at identical doses. The 120mg orlistat works by inhibiting lipase enzymes in your digestive system, blocking approximately one third of dietary fat from being absorbed. This unabsorbed fat passes naturally through your body, supporting weight management when used alongside a reduced-calorie, lower-fat diet.
Price Comparison: Significant Savings Available
The primary difference between these medications is cost. Generic Orlistat 120mg costs £32.99 (£29.69 with EDM10) for a 4-week supply, whilst branded Xenical costs £42.99 (£38.69 with EDM10) for the same period. Over 12 weeks, you could save over £30 by choosing generic orlistat. Both options deliver identical clinical effects, so your choice depends on whether you prefer branded medication or value savings.
Alli 60mg: Lower-Strength Alternative
For those preferring a gentler starting point, Alli 60mg contains half the orlistat dose of prescription-strength options. At £54.99 (£49.49 with EDM10) for 8 weeks, Alli offers a lower-strength alternative that may suit individuals wanting to begin with reduced intensity. However, the clinical effect is proportionally lower than 120mg formulations.
Same Clinical Assessment Process
Whether choosing generic Orlistat or branded Xenical, both require the same online clinical assessment by qualified UK-licensed prescribers. Our Leicester-based GPhC-registered pharmacy reviews your medical history, current medications, and BMI to determine treatment suitability. The prescription process is identical - only your choice of generic versus branded differs.
How to Choose Between Orlistat and Xenical
Choose generic Orlistat 120mg if you prioritise cost savings whilst receiving identical clinical benefits. The generic version contains the same orlistat ingredient, manufactured to identical standards, and delivers the same fat-blocking effect. Choose Xenical 120mg if you prefer branded medication from Roche. Some patients feel more confident with established brand names, though the clinical effect remains identical to generic alternatives.
