On the subject in the title: Prescription portability between countries — the long version Working notes rather than a conclusion.
Documenting an access outcome, dated, because everything in this category expires.
As of May 2026, in my region, the position is as described below. I have linked the primary source rather than a summary of it, because the summaries are consistently a year behind.
If anyone can confirm or contradict this for their own region, please date your answer. An undated claim in this category is worse than no claim.
