Orlistat vs Xenical: Which Should You Choose?
Is Orlistat a GLP-1 Medication?
No, orlistat is not a GLP-1 medication. Orlistat works as a lipase inhibitor in your digestive system, blocking approximately one third of dietary fat from being absorbed. Unlike GLP-1 medications that affect hormones and appetite, orlistat acts locally in the gut without being absorbed into your bloodstream in significant amounts.
Orlistat vs Xenical: The Key Differences
Generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at identical doses. Both work by inhibiting lipase enzymes to reduce dietary fat absorption. The primary difference is cost - generic orlistat offers the same clinical effect at a lower price point.
Our 4-week supply comparison: Generic orlistat costs £32.99 (£29.69 with EDM10) versus Xenical at £42.99 (£38.69 with EDM10). This represents savings of approximately £9 per month when choosing generic orlistat over branded Xenical.

Which Option Should You Buy?
Both products are clinically equivalent and require prescription following assessment by a UK-licensed prescriber. Generic orlistat provides excellent value for cost-conscious patients, whilst some prefer branded Xenical. Both work identically when used alongside a reduced-calorie, lower-fat diet.
For those preferring a lower-strength option, Alli 60mg (half the prescription dose) is available: 4-week supply £28.99 (£26.09 with EDM10), offering a gentler introduction to orlistat therapy.
