How to Take Orlistat 120mg Correctly
Orlistat 120mg works by blocking approximately one third of dietary fat absorption when taken correctly. Take one 120mg capsule three times daily with each main meal containing fat - immediately before, during, or up to one hour after eating. If you miss a meal or eat a fat-free meal, skip that dose. This dosing schedule means 21 capsules per week, helping you calculate which pack size suits your treatment duration.
2-Week Supply Options (42 Capsules)
Perfect for starting your weight management journey or trying orlistat for the first time. Generic orlistat 2-week supply costs £16.89 (£15.20 with EDM10), whilst branded Xenical costs £21.50 (£19.35 with EDM10). Both contain identical 120mg orlistat and require prescription following clinical assessment. Many patients start with 2-week packs to assess tolerance before ordering larger supplies.
4-Week Supply - Most Popular Choice (84 Capsules)
Our 4-week packs offer excellent value whilst providing sufficient treatment duration to establish routine. Generic orlistat 4-week supply costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). This pack size allows patients to monitor progress and side effects over a full month of treatment alongside their reduced-calorie, lower-fat diet programme.
8-Week Supply for Continued Treatment (168 Capsules)
Ideal for patients established on orlistat who want to reduce ordering frequency. Generic orlistat 8-week supply costs £63.99 (£57.59 with EDM10) whilst Xenical costs £86.99 (£78.29 with EDM10). Eight-week packs provide significant savings per capsule and ensure treatment continuity. Perfect for patients who have completed initial assessment periods and want longer-term supplies.
12-Week Supply - Maximum Value (252 Capsules)
Our largest pack size offers the best value for established patients. Generic orlistat 12-week supply costs £95.99 (£86.39 with EDM10) whilst Xenical costs £128.99 (£116.09 with EDM10). Twelve-week packs provide the lowest cost per capsule and are ideal for long-term weight management programmes. All 12-week supplies include prescription and next-day delivery from our GPhC-registered Leicester pharmacy.
Orlistat vs Xenical - Choosing Between Generic and Branded
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose. The clinical effect is equivalent - both block approximately one third of dietary fat absorption when used correctly. Generic orlistat offers significant cost savings, with 4-week supplies costing £9 less than Xenical. Some patients prefer branded Xenical whilst others choose generic orlistat for value. Your prescriber can advise which option suits your needs and budget.
Lower-Strength Option: Alli 60mg
Alli provides half the dose of prescription-strength orlistat at 60mg per capsule. Available in 4-week (£26.09 with EDM10), 8-week (£49.49 with EDM10) and 12-week (£116.99 with EDM10) supplies. Alli blocks a smaller proportion of dietary fat compared to 120mg versions, making it suitable for patients preferring lower-strength treatment. Take one 60mg capsule three times daily with main meals containing fat.
