Editorial policy
How we research and write
Medical information has to be right. This is how we try to make sure it is, and what we do when it is not.
Sources first
Medical statements on this site come from primary sources: the official prescribing information (the FDA label, the EMA product information and the UK summary of product characteristics), published clinical trials, and guidance from regulators and health services such as NICE, the NHS and national medicines agencies. Each claim that could change or be disputed carries a numbered reference to its source.
Country information (availability, strengths, public funding, prices, rules on pharmacies) comes from regulators, public price lists and suppliers' own published pages, and shows the date it was last checked.
How pages are written
Pages are researched and drafted with the help of AI tools working from the sources above, then checked and edited by a person before publication. We write plainly, avoid hype, and describe what the evidence shows, including its limits. We do not describe any medicine as the best, and we do not make claims a medicine's licence does not support. Where we have not yet had a page reviewed by a pharmacist or doctor, we do not say that it has been.
Keeping it current
Each page shows when it was last updated. Prices and availability are rechecked regularly; when a regulator or manufacturer announces a change we update the affected pages. If you find an error, tell us and we will correct it and note the date.
Independence
No manufacturer, pharmacy or clinic reviews our content before publication or pays to influence it. Commercial relationships, where they exist, are described in how we make money and never change the order of a list, what we say about a supplier, or which suppliers we include.
