4 min read Updated 2026-01-15Reviewed against manufacturer prescribing information

Generic Orlistat contains the same active molecule as Xenical / Alli and must demonstrate bioequivalence to be approved. The difference between a good and a bad generic lies in the manufacturer, not the molecule.

Key takeaways

  • Bioequivalence means the generic delivers the same exposure within accepted limits.
  • GMP status and batch documentation are the real quality signals.
  • Generic Orlistat is available across 60 mg, 120 mg.
  • A batch-specific certificate of analysis should always be available on request.
