Which Should You Choose: Generic Orlistat or Branded Xenical?
Orlistat vs Xenical: The Key Differences
Both orlistat 120mg and Xenical 120mg contain identical active ingredients at the same dose. They work by blocking approximately one third of dietary fat absorption through lipase inhibition in the gut. The primary difference is cost - generic orlistat provides the same clinical effect at a lower price point.
Generic orlistat costs £29.69 for 4 weeks with code EDM10, whilst branded Xenical costs £38.69 for the same supply. Over 12 weeks, you'll save £29.70 by choosing orlistat (£86.39 vs £116.09).
Side Effects: Do Both Cause Flatulence?
Yes, both orlistat and Xenical may cause gastrointestinal side effects including flatulence with or without discharge. These effects occur because unabsorbed fat passes through the digestive system. Side effects are more common with high-fat meals and typically reduce when keeping meals below 15g fat each.
The frequency and severity of side effects are identical between generic orlistat and Xenical - your choice shouldn't be based on tolerability differences.
Complete Pricing Comparison
Orlistat 120mg pricing: 2 weeks £15.20, 4 weeks £29.69, 8 weeks £57.59, 12 weeks £86.39 (all with EDM10). Xenical 120mg pricing: 2 weeks £19.35, 4 weeks £38.69, 8 weeks £78.29, 12 weeks £116.09 (with EDM10).
For those preferring a lower-strength option, Alli 60mg is available from £26.09 for 4 weeks with EDM10. This half-dose version typically causes milder side effects whilst still supporting weight management.
Our Recommendation
Most patients choose generic orlistat for the cost savings without compromising clinical effectiveness. However, some prefer the branded Xenical for peace of mind. Both require the same clinical assessment and are dispensed from our GPhC-registered pharmacy with identical service standards.
