How shortages have affected compounding permissions I have a specific reason for asking rather than idle curiosity, and the context is below.
I would like to know what people here actually do about shortages, as distinct from what is usually recommended. Those have diverged in every other subject I have looked at closely.
Mine is below, with the reasoning, including the parts I am not confident about.
Building on the opening post rather than restating it.
Careful with the language on shortages. "Not detected" and "not present" are different findings and the first is a statement about the method.
Shortage-driven price movement is real and is a separate question from availability.
It is the kind of thing that is obvious once and never again.
Post #5 is the version of this I will quote in future. One addition.
Shortage status determines what compounding is permitted in some jurisdictions, which links two questions that otherwise seem unrelated.
Posting my shortages numbers with the method attached so they can be discounted properly. Uncontrolled, unblinded, and collected by someone who wanted a particular answer.
Staff rationale: Hidden by community flags. The claim about a named supplier was not accompanied by a batch, a date, a method or a document, which R6 requires.
I have been on both sides of the shortages argument in this category within eighteen months, which should tell you how strong the evidence for either side is.
The corresponding entry is in the public moderation log. Hidden posts are never deleted.
That is a fair summary of where the discussion has got to.
The arithmetic in post #8 is right; the assumption feeding it is the part to check.
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).
It is worth checking rather than assuming, which costs nothing.
That is consistent with mine, for whatever one more account is worth.
Post #13 put the caveat in the right place and I want to underline it.
The published shortage register maintained by the national regulator is the authoritative source here, and it is updated far more often than any thread.
Reading it again, the caveat matters more than the finding.
Narrowing post #14, because the general version has more than one answer.
Anyone reporting availability should say the region and the date, because both determine whether the report is usable.
It is worth stating the boring hypothesis before the interesting one.
Everything in post #13 holds. The case it does not cover is the one I have.
Shortage predictions: regulators and suppliers issue shortage alerts before they become acute. Checking the regulatory website for shortages gives you advance notice.
Not disagreeing with anyone above, just adding the bit I keep having to look up.
An observation about shortages that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.
Both are useful and different. The notice tells you the national position; the account tells you what is happening on the ground.
The number people quote for shortages is a central estimate presented without its interval, and the interval is wide enough that the estimate is nearly uninformative on its own.
Shortages end and the notices are updated. Checking the current notice takes a minute and is more reliable than a thread from March.
Shortage predictions: regulators and suppliers issue shortage alerts before they become acute. Checking the regulatory website for shortages gives you advance notice.
That is all I can say without guessing.
Grateful for the specificity. Vague answers to this question are what sent me looking.
One caution on shortages: everything above assumes the underlying documentation is what it claims to be. That assumption is doing real work and is rarely stated.
Shortages was covered in the wiki last year and the page has a review date on it, which is a better starting point than my memory of a thread.
