Key Points to Know:

  • The new formulation has the same efficacy, safety profile, and method of administration as the original.
  • Rybelsus should always be taken as one tablet once daily.
  • Both formulations will temporarily co-exist on the market. This may lead to confusion or dosing errors, increasing the risk of adverse effects.
  • Patients currently taking Rybelsus should be informed about the change and advised accordingly when the new formulation is prescribed or dispensed.
  • New patients starting Rybelsus will begin treatment with the updated formulation.
