12 Apr 2021 to 18 Apr 2021: UK medicine supply changes
4 items dated 12 Apr 2021 to 18 Apr 2021, each a re-expressed fact linked to its source document. This week is over. Changes are filed by the date the source gives them, so this week can still gain one if a source is captured late. Protocol end dates and expected-back windows are shown as the NHSBSA register and the notices stood when last checked, not as they stood during this week: a later extension or update can move one of them to another week or remove it. Corrections are logged on the corrections page.
Sources are checked twice daily by scheduled jobs (not live). Last checked 2026-10-20 20:54 UTC. England first; Scotland in its own section, never summed. Absence from this page is not availability. Also as Atom and JSON.

Discontinuations · 0
Discontinuations stated in a notice, dated by the notice or update that states them.

Expected-back windows ending this week · 0
Notices whose current stated expected-back window ends this week. The end is derived from the phrase: the stated day where the source gave one; six days after a stated week-commencing day; otherwise the 10th for "early", the 20th for "mid" and the last day of the month for "late" or a bare month (six days after it for a "week commencing" phrase with no readable day). The sources mostly give phrases like "late July", not days, so each item says which rule applied.
None recorded for this week.
