Ustekinumab currently has availability issues reported in 3 European registers: Greece, Ireland, Italy.
Shortage ATC L04AC05 · also listed as: USTEKINUMAB · data refreshed 11 September 2026
As of 11 September 2026, 3 of the 9 tracked registers list current availability issues for Ustekinumab, covering 6 affected product presentations. The longest-running open report was filed in Italy on 2025-10-01 and has now been open for about 11 months. Where agencies state a cause, unexpectedly high demand lead with 2 of the 5 stated-cause reports, followed by delivery delays with 1. Notably, 3 reports have already passed the expected-resolution date without closing — prognoses for this medicine should be read as estimates, not commitments. Momentum is current, not historical: 2 of the open reports were filed within the last 90 days. The issue spread across registers over time rather than at once: Italy reported first (2025-10-01), with Ireland following roughly 8 months later — a pattern typical of supply problems cascading between national markets. Registers in Greece, Ireland, Italy indicate that alternatives or equivalents are available — a pharmacist or doctor can advise on switching. In the WHO ATC classification, Ustekinumab is coded L04AC05 — a medicine acting on antineoplastic and immunomodulating agents — so clinically related products appear under “Related medicines” below.
