Which Should You Buy: Generic Orlistat or Xenical?
How Long Before Orlistat Works
Both generic orlistat 120mg and branded Xenical 120mg work immediately once you start taking them with meals. Orlistat inhibits lipase enzymes in your gut, blocking approximately one third of dietary fat absorption from your first dose. You may notice effects within 24-48 hours, particularly if you eat higher-fat meals. However, meaningful weight management results typically develop over weeks when combined with a reduced-calorie, lower-fat diet and increased physical activity.
Orlistat vs Xenical: The Facts
Generic orlistat and Xenical contain exactly the same active ingredient at identical 120mg strength. Both are clinically equivalent prescription medicines that work by the same mechanism. The primary difference is cost—choosing generic orlistat over Xenical can save you approximately £9 per month. At EverydayMeds, orlistat 84 capsules (4-week supply) costs £29.69 with EDM10 discount, while Xenical costs £38.69 for the same quantity.
Some patients prefer branded Xenical, while others choose generic orlistat for better value. Both require the same online clinical assessment by UK-licensed prescribers and are dispensed by our GPhC-registered pharmacy in Leicester.
Pricing Comparison: Orlistat vs Xenical
Generic Orlistat 120mg pricing: 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 with EDM10 discount. Xenical 120mg pricing: 2 weeks £19.35, 4 weeks £38.69, 8 weeks £78.29, 12 weeks £116.09 with EDM10. The savings with generic orlistat are significant over longer treatment periods.
Alli 60mg: Lower-Strength Alternative
Alli 60mg offers half the dose of prescription-strength orlistat and may be suitable for those preferring a lower-strength starting point. At EverydayMeds, Alli costs £26.09 for 4 weeks with EDM10 discount. While less potent than 120mg options, Alli blocks a smaller proportion of dietary fat with typically milder gastrointestinal side effects.
