This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
Shortage-driven price movement is real and is a separate question from availability.
Post #61 is right about the mechanism and I think understates the practical bit.
Reports that a pharmacy has stock are the least durable information on the site and are still worth posting with a date.
Old habit: I write down the expected answer before I calculate it.
On post #61 — agreed on the reasoning, with one qualification.
International supply chains: a shortage in one country does not mean shortage in another. That is why ordering from multiple suppliers before a shortage gets bad is prudent if you can.
I have said this before in a thread nobody could find, so it is worth repeating.
Nothing to add, except that this is the answer I would give if asked.
Shortage-driven price movement is real and is a separate question from availability.
Posted with less confidence than the sentence structure implies.
Post #65 put the caveat in the right place and I want to underline it.
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).
Reporting the observation and leaving the explanation open deliberately.
Right, and stated more narrowly than I would have dared to state it.
Reports that a pharmacy has stock are the least durable information on the site and are still worth posting with a date.
I read post #70 twice before replying, because I had assumed the opposite.
Switching presentation or strength during a shortage is a prescribing decision rather than a substitution anybody should improvise.
That is the shape of it. The detail is where I would expect to be corrected.
Where an alternative within the class is available, the comparison is a clinical one and the doses are not equivalent.
Two people can read the same figure differently here and both be reasonable.
On post #74 — agreed on the reasoning, with one qualification.
Both are useful and different. The notice tells you the national position; the account tells you what is happening on the ground.
Noting that the question and the thing people usually mean by it are different.
Post #76 is right about the mechanism and I think understates the practical bit.
Pharmacy-level availability varies enormously during a shortage, so two honest accounts from the same city can be opposite.
Written quickly, so the reasoning may be tighter than the wording.
Building on post #76 rather than restating it.
Regional differences during a shortage are large, and a supply position in one country says nothing about another.
I would call that likely rather than established.
This is the answer, and the reason it is the answer is the more useful part.
I had written a reply contradicting post #79 and deleted it. Here is what survived.
Anyone reporting availability should say the region and the date, because both determine whether the report is usable.
None of the above is medical advice and I am not qualified to give any.
Shortage-driven price movement is real and is a separate question from availability.
Picking up post #82: that is the part I would want checked first.
Where a shortage forces a gap, the pharmacokinetics mean a missed week is a perturbation rather than a reset, which is worth knowing.
The honest answer is that it depends, and here is what it depends on.
Coming back to post #84, because the follow-up matters more than the original answer.
Reports that a pharmacy has stock are the least durable information on the site and are still worth posting with a date.
I looked this up rather than remembered it, which is the right order.
Post #84 is right about the mechanism and I think understates the practical bit.
Manufacturer allocation decisions during a shortage are commercial and are rarely explained, which is frustrating and is not evidence of anything.
That is where I would start, not where I would stop.
Planning around a known shortage window is easier than reacting to one, and the notices give advance warning more often than people expect.
It is the sort of thing that seems obvious in retrospect and was not at the time.
