Report a correction or source update
Help us keep this resource accurate. Include the page URL, the specific statement and a reliable source that supports your correction. For a product update, identify the exact product and market version. This is an editorial contact route, not a medical advice service.
Please do not submit medical records, treatment photographs or other sensitive health information. For a personal treatment concern, contact your treating healthcare professional.

How corrections are evaluated
A correction should be checked against the original source and the context of the claim. Material errors require changes to affected pages and a clear revision note; connected guides should also be checked. Unresolved claims should be qualified or withheld.
Meaningful update dates
Substantive changes receive an updated date. A typography or layout edit does not imply that all medical evidence has been reviewed again. A corrected conclusion should identify what changed and why.
