[Discussion] the shortage list advice in here is 3 years out of date
the shortage list advice in here is 3 years out of date, and I am aware this is a minority view on this board.
The numbers the title promised, since a headline without them is worthless: 3 years. Everything below is context for those.
Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.
Switched between two compounded preparations and the concentration on the label was different. Redid the arithmetic on paper before drawing anything.
Tell me where this is wrong. That is the useful part of posting it.
best — the order this archive was captured in
Nothing in this thread is medical advice, and the choice between arrangements is one for you and a prescriber who knows your history.
503A is patient-specific, 503B is outsourcing facility, they are not the same thing
The intake asked me three questions and none of them were about my history. That told me everything I needed to know about the model.
Right, and the concentration genuinely can differ from the branded product, which breaks people’s arithmetic.
Careful. Naming a clinic without describing what actually happened turns this into a different kind of thread.
Same view. If the intake asked you nothing, the intake was a formality and you should factor that in.
This. Compounded preparations carry no equivalence claim, and treating them as generics is a category error people make constantly.
This.
Disagreeing with this bit: registration is not equivalence, and the two get run together constantly.
the shortage list is the whole legal hinge and people skip it
Added a jurisdiction tag — the answers to this question are completely different in different countries.
Who is the prescriber, and are they the same organisation as the pharmacy?
Cosigning the beyond-use date question. What it is based on tells you whether anybody has done stability work.
What is the beyond-use date and what is it based on?
Asked which facility and got a name straight away. Looked it up, found the registration, felt considerably better about the whole thing.
ask which facility, then ask for their testing
Small fix — 503B facilities register with the regulator; 503A pharmacies are licensed by the state board. Different mechanisms.
Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.
do not assume the concentration matches the branded product
Concentration on the compounded vial was different from what I had been using and I nearly did the arithmetic on autopilot.
a telehealth intake that asks nothing has told you what it is
salt forms are the recurring argument and the answer is boring
That figure is the starting material purity, not the finished preparation potency. Two different tests.
That is not what patient-specific means. It refers to the prescription, not to a customisation of the formula.
Kept the label from every vial. When the shortage status changed, having the paper trail made the conversation much shorter.

The shortage list is the legal hinge: the permissions that allow certain compounding to happen at scale are tied to a drug’s shortage status, which changes.
Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.
The five questions worth asking before you commit to any compounded arrangement.
Which facility, by name. Whether it is a 503A pharmacy or a 503B outsourcing facility. What concentration is on the label. What the beyond-use date is based on. Whether there is potency testing on the finished preparation rather than only on the starting material.
All five are answerable in one email and the pattern of what comes back is more informative than any of the individual answers. An organisation with a quality system finds these questions ordinary.

prior_auth_pain is right about the concentration trap. It breaks arithmetic that has been reliable for months.
