Denials are usually procedural rather than clinical, and the order that works reflects that.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. Import rules are jurisdiction-specific and this board keeps giving US-shaped answers to non-US questions. What is a personal-import allowance in one country is a controlled-import offence in another.

One order arrived in nine days, one was held at the border for a fortnight, and one came back with a seizure notice.

International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:

Package cleared customs in 2 days, no issues.

Tips: always include a copy of your prescription, declare medication properly on customs forms, keep quantities reasonable (personal use = 3 month supply max), and use a vendor who has experience shipping to your country.

Coming at Dr.GutHealth’s question from a different direction. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.

Following on from tammy_FL — and this may be the naive question:

What actually works on a prior-authorisation denial, as opposed to the list of things that sound like they should work?

Closing the loop on my own question.

Update: approved on the third attempt after a peer-to-peer. Nothing about my case changed; only who was doing the talking.
