Compare Prescription Weight Loss Options vs Alli

How Alli Compares to Prescription Orlistat

Alli 60mg works by blocking approximately one third of dietary fat absorption, but prescription orlistat 120mg contains double the active ingredient strength. While Alli is available without prescription, orlistat 120mg requires clinical assessment and may provide more comprehensive weight management support when used alongside a reduced-calorie, lower-fat diet.

Prescription Orlistat 120mg - Generic Option

Generic orlistat 120mg offers the same clinical effect as branded alternatives at exceptional value. Available from £16.89 for 2 weeks (£15.20 with EDM10 discount), this prescription weight loss medication works in your digestive system to reduce dietary fat absorption. Our 4-week supply costs £32.99 (£29.69 with EDM10), while 12-week treatment is £95.99 (£86.39 with EDM10).

Xenical 120mg - Branded Prescription Option

Xenical contains the same orlistat 120mg active ingredient as generic versions but is manufactured by Roche. Some patients prefer this branded option, available from £21.50 for 2 weeks (£19.35 with EDM10). A 4-week Xenical supply costs £42.99 (£38.69 with EDM10), with 12-week treatment at £128.99 (£116.09 with EDM10).

How Prescription Weight Loss Treatment Works

Orlistat acts locally in your gut, inhibiting lipase enzymes that break down dietary fat. This unabsorbed fat passes naturally through your system rather than being stored. The medication works best when combined with meals containing no more than 15g fat, helping minimise gastrointestinal side effects while supporting your weight management goals.

Online Clinical Assessment Process

Our UK-licensed prescribers review your medical history, current medications, and weight management goals through a comprehensive online consultation. If clinically appropriate, your prescription is issued and dispensed by our GPhC-registered Leicester pharmacy. Treatment includes discreet next-day delivery across the UK, with no separate GP appointment needed.

Who May Be Suitable for Prescription Treatment

Orlistat 120mg may be prescribed for adults with BMI 30+ or BMI 28+ with weight-related health conditions like type 2 diabetes or high blood pressure. Individual suitability is assessed during clinical consultation, ensuring treatment safety and effectiveness alongside your reduced-calorie diet plan.
