MHRA Alert – Rybelsus (semaglutide) formulation transition and medication error risk

Medication Safety Alert: Rybelsus® Formulation Change

The MHRA has issued a safety alert regarding a planned transition to a new formulation of Rybelsus® (semaglutide tablets). During this transition period, both the original and new formulations will be in circulation. Although bioequivalent, they carry different stated mg doses, creating a significant risk of medication error.

Key Points

  • Two formulations of Rybelsus® will coexist during the transition period
  • Different stated doses despite bioequivalence increases confusion risk
  • Medication errors could result in patient harm
  • All clinical and pharmacy staff involved in dispensing, administration, and patient counselling should be aware of this change

Affected Medication

  • Rybelsus® (semaglutide tablets) – all strengths

Recommended Actions

  • Review your local prescribing and dispensing protocols for semaglutide tablets
  • Ensure all staff are briefed on the formulation transition and the risk of confusion
  • Double-check prescriptions and dispensing records, particularly during the transition period
  • Reinforce patient counselling to confirm the correct formulation and dose
  • Report any suspected medication errors or near-misses to your local reporting system and the MHRA Yellow Card scheme
