Choose Your Orlistat Pack Size - Best Value Options
Orlistat Pack Sizes - Which Supply Length is Right for You?
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 for all three orlistat products - generic Orlistat 120mg, branded Xenical 120mg, and lower-strength Alli 60mg.
Generic Orlistat 120mg - Most Cost-Effective Option
Generic orlistat 120mg offers the best value for prescription weight loss treatment. Available pack sizes include: 2-week supply (42 capsules) at £16.89 (£15.20 with EDM10), 4-week supply (84 capsules) at £32.99 (£29.69 with EDM10), 8-week supply (168 capsules) at £63.99 (£57.59 with EDM10), and 12-week supply (252 capsules) at £95.99 (£86.39 with EDM10). The 12-week pack provides maximum savings per capsule whilst ensuring consistent treatment.
Xenical 120mg - Branded Orlistat Option
Xenical contains the same active ingredient as generic orlistat at identical strength but at a premium price. Pack options include: 2-week supply at £21.50 (£19.35 with EDM10), 4-week supply at £42.99 (£38.69 with EDM10), 8-week supply at £86.99 (£78.29 with EDM10), and 12-week supply at £128.99 (£116.09 with EDM10). Some patients prefer the branded option, though generic orlistat delivers clinically equivalent results.
Alli 60mg - Lower Strength Alternative
Alli provides half the dose of prescription-strength orlistat and may be suitable for those preferring a gentler starting point. Available in: 4-week supply (42 capsules) at £28.99 (£26.09 with EDM10), 8-week supply (84 capsules) at £54.99 (£49.49 with EDM10), and 12-week supply (252 capsules) at £129.99 (£116.99 with EDM10).
Why Longer Pack Sizes Offer Better Value
Purchasing longer supplies provides significant cost advantages. The 12-week generic orlistat pack saves over £10 compared to buying six 2-week packs. Additionally, longer supplies reduce delivery frequency and ensure treatment continuity. Most patients find 8-12 week supplies optimal for establishing sustainable weight management routines alongside dietary changes.
How Orlistat Works - Why Pack Size Matters
Orlistat works by blocking approximately one third of dietary fat absorption in the gut. This mechanism requires consistent daily dosing - one 120mg capsule three times daily with meals containing fat. Irregular dosing reduces effectiveness, making adequate supply essential. Each weekly supply contains 21 capsules, so calculate your needs accordingly when selecting pack sizes.
Clinical Assessment Required for All Prescriptions
All orlistat 120mg and Xenical products require prescription following clinical assessment by a UK-licensed prescriber. Our online consultation process reviews your medical history, current medications, and weight management goals. Treatment suitability is assessed individually - not everyone will be eligible. The prescriber determines appropriate pack size based on your treatment plan and previous response to orlistat.
