Pharmaceutical compounding rules, summarised from primary sources posts 151–164

Pharmaceutical compounding rules is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

An honest declaration on pharmaceutical compounding rules: I have a prior here and it is strong enough that you should weight what I say downward. Stating it rather than hiding it.

I read post #151 twice before replying, because I had assumed the opposite.

Compounding and pharmacy rules: some jurisdictions allow a pharmacy to compound a drug that is not on the market under specific conditions. The conditions are strict and vary by jurisdiction. Generalising from one country's rules to another's is unreliable.

Adding it in case it saves somebody the afternoon it cost me.

Import restrictions vary by compound and by jurisdiction: what is a controlled substance in one place is legal to purchase in another. What you can import for personal use depends on your country's rules, not on where it is sold.

For what it is worth, the same held on the two occasions I checked.

Small methodological point on pharmaceutical compounding rules: repeating a measurement is cheap and resolves most of what is being argued about here at no cost to anyone.

Where a claim about legality is made here, the useful follow-up is which instrument it rests on. Most such claims turn out to rest on a forum post.

If the premise is wrong, everything after it is decoration.

A compound in a compounding pathway in one country and unavailable in another is a common situation and produces most of the confusion here.

On post #155 — agreed on the reasoning, with one qualification.

Primary documents matter: regulatory positions are published in official documents. Reading the regulatory agency's website directly is more reliable than reading a forum summary of it.

I would be glad to be shown a cleaner way of putting this.

Picking up post #159: that is the part I would want checked first.

I changed my mind about pharmaceutical compounding rules after someone here asked me for the source and I could not produce one. That is worth saying out loud because it is the ordinary way it happens.

If you can confirm or contradict a position for your own region, please date the answer. An undated regional claim is the least useful thing in this category.

I have left out the parts I could not verify.

Building on post #160 rather than restating it.

Pharmaceutical compounding rules came up in a thread eighteen months ago and was answered well. I cannot find it, which is itself the problem, so here is the reconstruction.

Post #162 put the caveat in the right place and I want to underline it.

Contradicting a claim in this subcategory is most useful when it comes with a link to the primary source and a date of access.
