Choose the Right Orlistat Pack Size for Your Needs
How Long Does Orlistat Take to Work?
Orlistat begins working immediately after taking your first capsule, blocking approximately one third of dietary fat from being absorbed. However, noticeable weight management effects typically develop over 2-4 weeks when used alongside a reduced-calorie, lower-fat diet and increased physical activity. This is why choosing the right pack size matters for your treatment success.
2-Week Supply: Perfect for Starting Treatment
Our 2-week orlistat supply (42 capsules) is ideal for first-time users who want to assess tolerance and suitability. Generic orlistat 120mg costs just £16.89, or £15.20 with code EDM10. Xenical 120mg (branded equivalent) is available for £21.50, reduced to £19.35 with EDM10. This shorter supply lets you evaluate how your body responds before committing to longer treatment periods.
4-Week Supply: Most Popular Choice
The 4-week supply (84 capsules) represents our most popular pack size, providing sufficient time to establish a routine and see initial weight management benefits. Orlistat 120mg costs £32.99 (£29.69 with EDM10), while Xenical 120mg is £42.99 (£38.69 with EDM10). Alli 60mg 4-week supply is £28.99 (£26.09 with EDM10). This duration aligns with typical clinical assessment timelines.
8-Week Supply: Better Value Option
For sustained weight management support, our 8-week supply (168 capsules) offers improved value per capsule. Orlistat 120mg is priced at £63.99 (£57.59 with EDM10), compared to £86.99 for Xenical (£78.29 with EDM10). Alli 60mg 8-week supply costs £54.99 (£49.49 with EDM10). This pack size suits patients committed to longer-term treatment following successful initial assessment.
12-Week Supply: Maximum Savings
Our 12-week supply (252 capsules) provides the best cost per capsule for established users. Orlistat 120mg costs £95.99 (£86.39 with EDM10), offering significant savings versus shorter packs. Xenical 120mg 12-week supply is £128.99 (£116.09 with EDM10), while Alli 60mg costs £129.99 (£116.99 with EDM10). This option suits patients with established tolerance and ongoing treatment plans.
Generic Orlistat vs Xenical: Same Effect, Different Price
Both orlistat 120mg and Xenical 120mg contain identical active ingredients at the same dose, providing clinically equivalent effects. The primary difference is cost - generic orlistat offers savings of approximately £9-33 depending on pack size, while maintaining the same fat-blocking mechanism. Both require prescription following online clinical assessment by our UK-licensed prescribers.
