Shortage ATC — · also listed as: ACETYLCYSTEIN · Acetylcysteine · ACETILCISTEINA · data refreshed 8 September 2026
As of 8 September 2026, 3 of the 9 tracked registers list current availability issues for Acetylcysteine, covering 8 affected product presentations. The longest-running open report was filed in Ireland on 2023-02-01 and has now been open for about 43 months. Where agencies state a cause, manufacturing problems lead with 2 of the 5 stated-cause reports, followed by commercial decisions or discontinuation with 1. The furthest expected-resolution date currently on file is 2026-12-31; the earliest is 2026-10-16. 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: 5 of the open reports were filed within the last 90 days. The issue spread across registers over time rather than at once: Ireland reported first (2023-02-01), with Italy following roughly 37 months later — a pattern typical of supply problems cascading between national markets. Registers in Ireland, Italy, Sweden indicate that alternatives or equivalents are available — a pharmacist or doctor can advise on switching.
