Orlistat, Xenical or Alli - Which Is Right for You?
All three medications contain the same active ingredient - orlistat - which works by blocking approximately one third of dietary fat absorption. Following an online clinical assessment, your UK-licensed prescriber will determine which option may be most suitable for your individual circumstances.
Orlistat 120mg - Most Cost-Effective Option
Generic orlistat 120mg capsules provide the same clinical effect as branded alternatives at the lowest cost. Available in 2-week supplies (42 capsules) for £15.20 with EDM10, 4-week supplies (84 capsules) for £29.69, 8-week supplies (168 capsules) for £57.59, or 12-week supplies (252 capsules) for £86.39. Take one capsule three times daily with each main meal containing fat.
Xenical 120mg - Branded Prescription Treatment
Xenical contains identical orlistat 120mg to the generic version but is manufactured by Roche. Some patients prefer the branded option. Available from £19.35 for 2 weeks with code EDM10, £38.69 for 4 weeks, £78.29 for 8 weeks, or £116.09 for 12 weeks. Clinically equivalent to generic orlistat with the same dosing schedule.
Alli 60mg - Lower Strength Alternative
Alli provides half the dose of prescription-strength orlistat at 60mg per capsule. This lower strength option may suit those preferring a gentler starting point. Available for £26.09 for 4 weeks with EDM10, £49.49 for 8 weeks, or £116.99 for 12 weeks. Take one capsule three times daily with meals containing fat.
How These Medications Support Weight Management
Orlistat works locally in your digestive system by inhibiting lipase enzymes that break down dietary fat. When these enzymes are blocked, approximately one third of the fat you eat cannot be absorbed and passes naturally through your body. This can support weight reduction when used alongside a reduced-calorie, lower-fat diet and increased physical activity.
