How corrections work

  • Anyone can report a problem with the “Tell us” link at the bottom of every page, or through the contact form.
  • We check the report against the primary source (the label, regulator page or study) and aim to fix factual errors within two working days.
  • When a fix changes a number, dose or rule, the page's “Updated” date changes too.
