The Medicines Management Programme (MMP) has identified best-value biological (BVB) medicines for medicinal products containing ustekinumab.

The MMP recommends the following as BVB medicines for ustekinumab:

  • Imuldosa® (Accord Healthcare Ireland Limited)
  • Otulfi® (Fresenius Kabi Ireland)
  • Pyzchiva® (Sandoz Limited trading as Rowex)

Clinicians should give due consideration to prescribing Imuldosa®, Otulfi®, Pyzchiva® or Wezenla® when issuing a prescription for ustekinumab for the treatment of plaque psoriasis, psoriatic arthritis or Crohn’s disease.

The MMP recommends that:

  • all new patients being initiated on ustekinumab for the treatment of plaque psoriasis, psoriatic arthritis or Crohn’s disease should be prescribed a BVB medicine
  • patients currently established on ustekinumab for the treatment of plaque psoriasis, psoriatic arthritis or Crohn’s disease should be considered for switching to a BVB medicine at the earliest possible opportunity.
