Which Orlistat Pack Size Should You Choose?
Understanding Orlistat Pack Sizes and Treatment Duration
When starting orlistat treatment, choosing the right pack size depends on your treatment plan and commitment to weight management. Our GPhC-registered pharmacy stocks all standard pack sizes for orlistat 120mg (generic), Xenical 120mg (branded), and Alli 60mg. Each capsule is taken three times daily with meals containing fat, so weekly requirements are consistent at 21 capsules per week.
2-Week Supply (42 Capsules) - Starting Your Journey
Our 2-week orlistat supply costs £16.89 (£15.20 with EDM10) and provides an ideal starting point for new patients. This allows you to assess tolerance and adapt to the lower-fat diet essential for minimising gastrointestinal side effects. Generic orlistat 42-capsule packs offer the same clinical effect as Xenical at a lower cost. Perfect for those wanting to trial the medication before committing to longer supplies.
4-Week Supply (84 Capsules) - Building Routine
The 4-week pack (£32.99, £29.69 with EDM10) represents our most popular choice for established patients. This duration allows proper assessment of treatment response whilst building sustainable dietary habits. Xenical 4-week packs cost £42.99 (£38.69 with EDM10). Both options require the same online clinical assessment and provide identical fat-blocking effects - orlistat inhibits approximately one third of dietary fat absorption.
8-Week Supply (168 Capsules) - Better Value Treatment
Eight-week supplies offer improved value at £63.99 for generic orlistat (£57.59 with EDM10) versus £86.99 for Xenical (£78.29 with EDM10). This duration suits patients established on treatment who have adapted their diet successfully. The longer supply reduces reordering frequency whilst maintaining consistent treatment. Most patients experience reduced side effects by week 8 as dietary adjustments become routine.
12-Week Supply (252 Capsules) - Maximum Savings
Our 12-week packs provide the best value per capsule - orlistat 120mg costs £95.99 (£86.39 with EDM10) compared to £128.99 for Xenical (£116.09 with EDM10). This represents significant savings for committed patients following structured weight management programmes. The 12-week duration aligns with standard medical review intervals whilst maximising convenience and cost-effectiveness.
Alli 60mg Pack Options
Alli 60mg offers lower-strength orlistat in 4-week (£28.99, £26.09 with EDM10), 8-week (£54.99, £49.49 with EDM10) and 12-week (£129.99, £116.99 with EDM10) supplies. At half the prescription dose, Alli may produce milder effects and side effects, making it suitable for those preferring a gentler introduction to orlistat treatment.
