As of 06 Nov 2026 13:32 UTC. Status is always as stated in the latest recorded notice; the sources do not publish resolution, so nothing on this page says a medicine is back — see methodology.

Each line is re-expressed from MSN/2025/047 (24 Jul 2025): the product named, the status the source stated, and the expected-back phrase kept as written. Not the source's sentence, and not an observation of stock.
