Generic Orlistat vs Branded Xenical - Your Complete Guide
Orlistat vs Xenical: The Key Differences
When searching to order Xenical online UK, you'll encounter two prescription options: generic orlistat 120mg and branded Xenical 120mg. Both contain the exact same active ingredient (orlistat) at the identical 120mg dose, meaning they work in precisely the same way - blocking approximately one third of dietary fat absorption in your digestive system.
The primary difference lies in cost. Generic orlistat offers substantial savings: a 4-week supply costs £29.69 (with EDM10 discount) compared to Xenical at £38.69 - saving you over £100 annually. Both require the same online clinical assessment by UK-licensed prescribers and deliver identical weight management support when used alongside a reduced-calorie, lower-fat diet.
Price Comparison: Orlistat vs Xenical
Here's how the costs compare for both prescription weight loss medicines:
Generic Orlistat 120mg: 2 weeks (42 capsules) £15.20, 4 weeks (84 capsules) £29.69, 8 weeks (168 capsules) £57.59, 12 weeks (252 capsules) £86.39 (all prices with EDM10).
Branded Xenical 120mg: 2 weeks (42 capsules) £19.35, 4 weeks (84 capsules) £38.69, 8 weeks (168 capsules) £78.29, 12 weeks (252 capsules) £116.09 (all prices with EDM10).
The savings are significant - choosing generic orlistat over Xenical saves approximately £30 on a 12-week supply, with identical clinical outcomes.
Which Should You Choose?
From a clinical perspective, generic orlistat and Xenical are therapeutically equivalent. Both inhibit lipase enzymes to reduce dietary fat absorption, both require three capsules daily with main meals, and both may cause similar gastrointestinal side effects when high-fat meals are consumed.
Many patients choose generic orlistat for the cost savings, whilst others prefer branded Xenical. The decision often comes down to personal preference and budget considerations. Your prescriber can discuss both options during your online clinical assessment.
Alternative: Alli 60mg
For those preferring a lower-strength option, Alli 60mg contains half the orlistat dose of prescription strength. Available without prescription, Alli costs £26.09 for 4 weeks (with EDM10). Whilst less potent than 120mg formulations, it may suit those wanting to start with a lower dose or who experience side effects with prescription strength.
How to Order Online
Ordering either orlistat or Xenical through our GPhC-registered pharmacy involves completing an online health questionnaire reviewed by UK-licensed prescribers. If clinically appropriate, your prescription is dispensed and dispatched for next day delivery across the UK. The prescription consultation is included in the price - no separate GP appointment needed.
Both medications require commitment to a reduced-calorie, lower-fat diet (approximately 15g fat per meal) to maximise effectiveness and minimise gastrointestinal side effects. A daily multivitamin is recommended due to potential reduced absorption of fat-soluble vitamins.
