pricing for mounjaro and wegovy weight loss

Wondering whether to choose generic orlistat or branded Xenical? Both contain the same active ingredient (orlistat 120mg) and work identically by blocking approximately one third of dietary fat absorption. The key difference is cost - generic orlistat starts from £15.20 for a 2-week supply with code EDM10, whilst Xenical costs £19.35. Both require prescription following clinical assessment by our UK-licensed prescribers. Treatment typically begins working with your first fatty meal, though weight management results develop over weeks when combined with a reduced-calorie, lower-fat diet.

Which Should You Choose: Generic or Branded?

Orlistat vs Xenical: The Clinical Facts

Both generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at identical doses. They work by blocking approximately one third of dietary fat absorption through inhibiting lipase enzymes in your digestive system. Clinically, there is no difference in effectiveness - both start working with your first meal containing fat, though weight management results develop over several weeks when combined with a reduced-calorie, lower-fat diet and increased physical activity.

Price Comparison: Substantial Savings Available

The primary difference lies in cost. Generic orlistat offers significant savings compared to branded Xenical. For a 4-week supply (84 capsules), orlistat costs £32.99 (£29.69 with EDM10 code) whilst Xenical costs £42.99 (£38.69 with EDM10). Over a typical 12-week treatment course, choosing generic orlistat saves approximately £30 compared to Xenical - £86.39 versus £116.09 with our 10% discount code EDM10.

When Do Both Treatments Start Working?

Both orlistat and Xenical begin working immediately with your first dose when taken with a meal containing fat. The medication blocks approximately one third of dietary fat from that specific meal within 1-2 hours of taking the capsule. However, meaningful weight management results typically develop over 4-12 weeks when treatment is combined with appropriate dietary changes. Most patients notice gastrointestinal effects within 24-48 hours if eating high-fat meals - these side effects indicate the medication is working but can be minimised by keeping fat intake to approximately 15g per meal.

Alli 60mg: The Lower-Strength Alternative

For those preferring a gentler starting point, Alli 60mg contains half the dose of orlistat found in prescription-strength products. At £26.09 for a 4-week supply (with EDM10), Alli offers a middle-ground option between no treatment and full-strength orlistat. Whilst clinically less potent than 120mg formulations, Alli may suit patients concerned about potential side effects or those wanting to trial orlistat treatment.

Making Your Decision: Value vs Brand Preference

Choose generic orlistat if cost-effectiveness is your priority - you receive identical clinical benefits at a lower price. The generic version undergoes the same regulatory approval process and meets identical quality standards. Choose Xenical if you prefer branded medication - some patients find reassurance in the original branded product. Both options require prescription following online clinical assessment by our UK-licensed prescribers and are dispensed by our GPhC-registered pharmacy in Leicester with discreet next day delivery.
