What the baseline shows
For each dose, the median is the middle advertised monthly price across the pharmacies we could read. The spread is the gap between the cheapest and the dearest for the same dose, in the same month.

Why you can check this
- The method is published in full and versioned, including what counts as a price and how we handle offers.
- Every figure links to the pharmacy page it came from, with the month it was read.
- This page earns nothing from any pharmacy listed. Healthcount does have commercial relationships with some pharmacies on other pages, disclosed in our affiliate disclosure.
- What we could not read this month is stated on the release rather than quietly dropped.
Journalists and researchers: figures are free to quote with attribution. For the underlying evidence on any row, or a comment, get in touch.
Why this is UK only, for now
The index covers UK online pharmacies because that is where we have enough coverage to publish a median honestly. The method sets a bar: a dose needs several independent pharmacies before a middle value means anything, otherwise one provider changing its price moves the whole headline.
Ireland and the United States do not clear that bar yet. Our Irish data covers two pharmacies, and the US market runs on published list prices and copay programmes rather than comparable advertised pharmacy prices, which is a different measurement problem rather than a smaller version of the same one. Extending the index means building the collection for those markets first. Until then we would rather publish one index we can defend than three we cannot.
In the meantime, prices for those markets are on the US prices page and the Ireland prices page, each with its own sources and dates.
