As of 7 August 2026, 4 of the 10 tracked registers list current availability issues for Donepezil hydrochloride, covering 11 affected product presentations. The longest-running open report was filed in Greece on 2025-11-15 and has now been open for about 9 months. Where agencies state a cause, delivery delays lead with 2 of the 4 stated-cause reports, followed by unexpectedly high demand with 2. The furthest expected-resolution date currently on file is 2027-02-08; the earliest is 2026-08-09. 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: Greece reported first (2025-11-15), with Austria following roughly 7 months later — a pattern typical of supply problems cascading between national markets. Registers in Spain, Greece, Ireland indicate that alternatives or equivalents are available — a pharmacist or doctor can advise on switching. In the WHO ATC classification, Donepezil hydrochloride is coded N06DA02 — a medicine acting on the nervous system — so clinically related products appear under “Related medicines” below.
