Cost per delivered dose, which is the number that matters

List prices versus negotiated prices: the price a pharmaceutical company publishes and the price an insurance company or pharmacy actually pays differ substantially. List price is not what anyone pays.

This follows post #8 rather than contradicting it.

Compute cost per delivered dose at your dose if you want a number you can act on. That requires knowing your dose, vial volume, and whether you are using a vial or a pen.

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.

Coming back to post #32, because the follow-up matters more than the original answer.

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

Biosimilars and future generics: as patents expire, biosimilar and generic versions might become available and prices might fall. That has already happened for some proteins; incretin agonist pricing might follow.

Thank you for the correction. I have edited my earlier post with a note rather than silently, so the thread still makes sense to read. The error was mine and it was the kind that comes from remembering a figure instead of looking it up.

Compute cost per delivered dose at your dose if you want a number you can act on. That requires knowing your dose, vial volume, and whether you are using a vial or a pen.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.
