How fresh the source is
Files updated regularly by the publisher (about monthly or more often); our copy is refreshed daily
Limits
Official reimbursement prices per unit, not what a patient paid: patients pay a share (usually 10-30%) at the pharmacy, which adds its own fees. Only medicines reimbursed by National Health Insurance; over-the-counter medicines and unlisted products are not included. A range spans all strengths and makers of one ingredient, so it mixes strengths; the price is per unit of the form shown (tablet, capsule, gram, millilitre), not per box. English names are matched through a built-in list of common ingredients; any ingredient can also be given in Japanese.
Rule
A figure built from records is shown only when at least 5 records sit behind it; official statistics are shown as such, with their reference period. See how we earn trust and the method.
