Shortage ATC J05AF10 · also listed as: Entecavir · Entecavir-Monohydrat · entekavirmonohydrat · data refreshed 11 September 2026
As of 11 September 2026, 6 of the 9 tracked registers list current availability issues for Entecavir, covering 12 affected product presentations. The longest-running open report was filed in Italy on 2022-08-08 and has now been open for about 49 months. Where agencies state a cause, manufacturing problems lead with 4 of the 6 stated-cause reports, followed by delivery delays with 1. The furthest expected-resolution date currently on file is 2026-12-31; the earliest is 2026-09-15. Momentum is current, not historical: 7 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 (2022-08-08), with Greece following roughly 47 months later — a pattern typical of supply problems cascading between national markets. Registers in Germany, Spain, Ireland, Italy, Sweden indicate that alternatives or equivalents are available — a pharmacist or doctor can advise on switching. In the WHO ATC classification, Entecavir is coded J05AF10 — a medicine acting on anti-infectives for systemic use — so clinically related products appear under “Related medicines” below.

Yes. As of 11 September 2026, availability issues are reported in: Germany, Spain, Greece, Ireland, Italy, Sweden. Availability is national — a shortage in one country does not mean it is short everywhere.
Agency prognoses on file range from 2026-09-15 to 2026-12-31. These are manufacturer-reported estimates and frequently move; check the linked register entry for the latest date.
10 of the active register entries indicate alternatives or equivalents (same active substance or an alternative treatment). Do not switch on your own — a pharmacist or prescriber can confirm the right substitute in your country.
Directly from the official medicines-agency registers that list Entecavir: BfArM (Germany), AEMPS CIMA (Spain), EOF limited-availability list (Greece), HPRA (Ireland), AIFA (Italy), Läkemedelsverket (Sweden). Every row on this page links to the underlying official record, and the dataset is refreshed from the primary sources every morning. Cross-language matching groups the same active substance across registers, so national spellings all resolve to this page.
