THE SHORT VERSION
- The site includes several ways to make information easier to find and read. Use whichever helps you.
Reading controls
On a guide, open “Make this easier to read” to adjust text size, use a simpler focus view or try the optional paced reader. The paced reader does not start automatically. Pause or close it whenever you need; your place in the full article is still available.
Keyboard and smaller screens
Links and controls have visible keyboard focus. The menu, guide filters, dose selectors and native disclosure panels can be used with a keyboard. A skip link moves directly to the main content. Wide tables can scroll horizontally on smaller screens.
Motion and alternatives
The interface respects reduced-motion preferences. Core guides and source links are present in the HTML and remain readable without JavaScript. Browser zoom and reader tools can also be used.
Tell us about a barrier
We do not claim a formal accessibility certification. If something prevents you using the site, send a short description with the page and device. There is no need to diagnose the technical cause.
Sources you can check
See the evidence hub for primary medicine and NHS sources, and our editorial policy for how we use them.
