Coming back to: Cost per delivered dose, which is the number that matters

On the subject in the title: Cost per delivered dose, which is the number that matters Working notes rather than a conclusion.

Documenting an access outcome, dated, because everything in this category expires.

As of January 2026, in my region, the position is as described below. I have linked the primary source rather than a summary of it, because the summaries are consistently a year behind.

If anyone can confirm or contradict this for their own region, please date your answer. An undated claim in this category is worse than no claim.

Compute cost per delivered dose at your dose if you want a number you can act on. Everything else is a comparison of packaging.

Posting it because the silence on this was starting to look like agreement.

I came in to disagree and I am leaving without a disagreement.

Cost per week at a maintenance dose is the figure most people actually want and least often calculate.

The cost of an independent submission is worth stating in these threads, because it is the main reason people do not do it.

Post #5 is the version of this I will quote in future. One addition.

Cost per milligram is the only comparison that survives format differences, but even then it needs care. A pen and a vial are not the same product and cannot be compared on price per milligram alone because dead volume, wastage, and number of doses actually obtainable differ.

Happy to expand any of that if it is the useful part.

Where I part company with post #4, and it is a narrow parting.

Cost per milligram is the only comparison that survives format differences, and even then it needs care.

Scoping that to what I have actually seen rather than what I have read.

This follows post #7 rather than contradicting it.

Price variation between pharmacies: identical prescriptions can cost different amounts at different pharmacies because pharmacies negotiate individually with insurers and manufacturers.

Somebody will have a better source than mine, and I hope they post it.

Worth separating two things that post #8 runs together.

A pen and a vial are not the same product. Dead volume, wastage and the number of doses actually obtainable all differ.

It is worth stating the boring hypothesis before the interesting one.
