MedDRA is maintained as a living terminology. Users can propose terminology changes through the MSSO change-request process rather than treating gaps or preferred local wording as permanent workarounds.
Core official resources
- MedDRA Self-Service Application — access to subscription credentials and Change Request IDs for authorised users.
- MedDRA homepage — links to WebCR and current change-request information.
Practical use
WebCR supports proposals for changes to MedDRA, including simple and complex terminology changes and SMQ-related requests. Acceptance is controlled through the MSSO/JMO review process; submitting a request does not mean the requested concept will necessarily be introduced.
