Which Should You Buy: Orlistat or Xenical?
Orlistat vs Xenical: Identical Effect, Different Price
Both orlistat 120mg and Xenical 120mg contain exactly the same active ingredient at the same dose. They work identically by blocking approximately one third of dietary fat absorption in your gut. The unabsorbed fat passes naturally through your body, supporting weight management alongside a reduced-calorie, lower-fat diet.
Generic orlistat costs £32.99 (£29.69 with EDM10) for a 4-week supply, while branded Xenical costs £42.99 (£38.69 with EDM10) for the same period. This represents a saving of approximately £9 monthly by choosing the generic version.
How Does Alli Weight Loss Work Compared to 120mg Options?
Alli 60mg contains half the dose of prescription-strength orlistat. While it blocks a smaller proportion of dietary fat compared to the 120mg versions, it may cause milder gastrointestinal side effects. Alli costs £28.99 (£26.09 with EDM10) for a 4-week supply of 42 capsules, taken three times daily with meals containing fat.
For maximum effect, most prescribers recommend the full 120mg dose, available as either generic orlistat or branded Xenical following clinical assessment.
Prescription Process and Delivery
All three products require clinical assessment by a UK-licensed prescriber. Complete our online medical questionnaire covering your BMI, medical history, and current medications. If treatment is deemed appropriate, your prescription will be dispensed by our GPhC-registered pharmacy in Leicester and delivered discreetly to your address with next day delivery available.
The prescription consultation is included in the price - no separate GP appointment needed. Use code EDM10 for 10% off every order.
Which Pack Size Should You Choose?
Start with a 4-week supply to assess tolerance and effectiveness. Longer supplies offer better value: 12-week orlistat costs £95.99 (£86.39 with EDM10) compared to three separate 4-week orders. Most patients find the first few weeks involve adjusting to the lower-fat diet that minimises gastrointestinal side effects.
Making Your Decision
Choose generic orlistat 120mg for the most cost-effective option with identical clinical effect to Xenical. Opt for Xenical 120mg if you prefer the branded version and don't mind paying extra. Consider Alli 60mg if you want to start with a lower dose, though the clinical effect will be reduced compared to prescription strength.
