Choose Your Ideal Pack Size for Weight Management
Orlistat Pack Sizes and Average Weight Loss Expectations
When considering orlistat for weight management, choosing the right pack size depends on your treatment goals and budget. Our GPhC-registered pharmacy offers flexible supply options from 2-week starter packs to cost-effective 12-week courses. Orlistat 120mg may help reduce the absorption of approximately one third of dietary fat when used alongside a reduced-calorie, lower-fat diet.
2-Week Supply - Trial Period (42 Capsules)
Perfect for first-time users wanting to assess tolerance. Orlistat 120mg costs £16.89 (£15.20 with EDM10), whilst Xenical 120mg costs £21.50 (£19.35 with EDM10). This starter pack allows you to experience how orlistat works with your dietary routine before committing to longer treatment. Many patients use this period to adapt to the recommended low-fat diet whilst monitoring for side effects.
4-Week Supply - Most Popular Choice (84 Capsules)
Our most requested pack size offers excellent value for those established on treatment. Orlistat 120mg costs £32.99 (£29.69 with EDM10), Xenical 120mg costs £42.99 (£38.69 with EDM10), and Alli 60mg costs £28.99 (£26.09 with EDM10). This monthly supply provides consistency whilst allowing regular prescriber review of your progress.
8-Week Supply - Extended Treatment (168 Capsules)
Ideal for patients achieving good results who want to reduce ordering frequency. Orlistat 120mg costs £63.99 (£57.59 with EDM10), Xenical costs £86.99 (£78.29 with EDM10), and Alli costs £54.99 (£49.49 with EDM10). Eight-week supplies offer better value per capsule compared to shorter packs whilst maintaining treatment momentum.
12-Week Supply - Maximum Savings (252 Capsules)
Our longest supply offers the best cost-per-capsule value for established users. Orlistat 120mg costs £95.99 (£86.39 with EDM10), representing significant savings compared to multiple shorter packs. Xenical 120mg costs £128.99 (£116.09 with EDM10), whilst Alli costs £129.99 (£116.99 with EDM10). This option suits patients achieving consistent weight management results.
Average Weight Loss Expectations with Different Pack Sizes
Individual results vary significantly, but clinical studies suggest orlistat may support weight loss when combined with appropriate dietary changes. The 2-week supply allows initial assessment, whilst 4-8 week supplies typically provide clearer indication of treatment response. The 12-week supply aligns with recommended treatment durations for assessing longer-term effectiveness. Always maintain realistic expectations and follow your prescriber's guidance.
Choosing Between Orlistat, Xenical and Alli
All three products contain orlistat but at different strengths. Orlistat 120mg and Xenical 120mg are clinically equivalent prescription-only medicines, with generic orlistat offering cost savings. Alli 60mg provides half the dose for those preferring a lower-strength option. Your choice may depend on budget, preference for branded versus generic medication, and desired potency level.
