Official shortage notices and what they authorise Writing it up because I had to work it out twice and would rather nobody else did.
Official shortage notices — I have the observation and I do not trust my interpretation of it, so I am posting the observation and holding the interpretation back.
Numbers, method and the conditions under which they were collected are below. Interpret them however they warrant.
Supply interruptions: official shortage notices are published by regulatory agencies. That is the correct primary source rather than pharmacy rumors or forum discussion.
Compounding during shortages: some jurisdictions allow pharmacy compounding when a marketed product is in shortage. That permission is jurisdiction-specific and time-limited (usually for the duration of the shortage).
Genuinely open to being wrong about this one.
The opening post is right about the mechanism and I think understates the practical bit.
Managing an unplanned gap: if a shortage causes a gap in treatment, the questions are how long the gap will be and how that affects your condition. Discussing with your clinician is prudent if the gap is weeks or longer.
Flagging that the sources on this are thinner than the confidence in the thread suggests.
On the opening post — agreed on the reasoning, with one qualification.
An update on my earlier Official shortage notices post: the pattern held for another six weeks and then stopped, which I did not predict and cannot explain.
Anyone reporting availability should say the region and the date, because both determine whether the report is usable.
If that is already documented somewhere, ignore me and link it.
I came in to disagree and I am leaving without a disagreement.
Building on post #9 rather than restating it.
Stockpiling in response to a shortage worsens it, which is true and is a poor argument to make to somebody who has run out.
Filing this under things that are true until someone shows me otherwise.
Dose hold versus tapering: if a temporary shortage forces a gap, holding your dose and resuming when supply returns is different from gradually tapering. The two are different decisions.
That is all I can say without guessing.
Post #10 answers the question as asked. The question underneath it is different.
The published shortage register maintained by the national regulator is the authoritative source here, and it is updated far more often than any thread.
Pharmacy-level availability varies enormously during a shortage, so two honest accounts from the same city can be opposite.
Switching presentation or strength during a shortage is a prescribing decision rather than a substitution anybody should improvise.
I would put a moderate confidence on that and no more.
Post #17 is the version of this I will quote in future. One addition.
Where a shortage forces a gap, the pharmacokinetics mean a missed week is a perturbation rather than a reset, which is worth knowing.
I read the earlier replies on Official shortage notices twice before writing this, because I had assumed the opposite and wanted to be sure I was disagreeing with what was said rather than what I expected.
Appreciated. The plain phrasing does more work here than a longer post would.
Reports that a pharmacy has stock are the least durable information on the site and are still worth posting with a date.
I have written this out at length because the short version keeps being misread.
Official shortage notices has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.
Worth separating two things that post #23 runs together.
Shortages end and the notices are updated. Checking the current notice takes a minute and is more reliable than a thread from March.
Noting that the question and the thing people usually mean by it are different.
This follows post #25 rather than contradicting it.
Manufacturer allocation decisions during a shortage are commercial and are rarely explained, which is frustrating and is not evidence of anything.
Official shortage notices: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle this.
Picking up post #28: that is the part I would want checked first.
The arithmetic on Official shortage notices is the easy part and it is where the errors are, which is an uncomfortable combination. Show your working and someone will catch it.
