MedDRA Training Online: A Live Practice Tool, Not a Course

How to learn MedDRA

Learning MedDRA has two halves, and most training programs only cover one of them. The first half is conceptual: understanding the five-level hierarchy (SOC, HLGT, HLT, PT, LLT), knowing what a verbatim term is, and learning the coding conventions the MSSO publishes. That's the part a course, a manual, or an internal SOP covers well.

The second half is procedural fluency — actually being fast and accurate at taking a real (or realistic) verbatim and finding the right term in the dictionary. That skill only comes from repetition against the real thing, the same way you don't learn to drive by reading the manual twice. This is the half MedDRA Learner trains: search, browse, and code live against the MedDRA dictionary, with an AI tutor that nudges you toward the right answer instead of just handing it over.

MedDRA training for pharmacovigilance

If you're training for a pharmacovigilance coding role, the day-to-day skill you'll be judged on is LLT selection — taking a verbatim adverse event as reported by a patient or reporter and mapping it to the closest Lowest Level Term. MedDRA's own coding convention is to always code to the LLT nearest the term as reported, so that's exactly what practicing here builds. Every lookup and coding decision is logged to an append-only audit trail, the same discipline a real case-processing environment expects from day one.

MedDRA training for clinical trials

Clinical trial teams — CRAs, data managers, safety reviewers — use MedDRA differently than a PV case processor does, but the underlying skill is the same: read a reported term, find where it sits in the hierarchy, and code it consistently. If your organization runs its own MedDRA subscription, an Enterprise account gives your associates individual logins and full SOC-to-LLT visibility for structured onboarding, without touching your live coding queue or pooling one shared MedDRA login across the team.

Two ways to train

MedDRA Learner splits by whether you hold a MedDRA subscription personally:

• Individual / public tier — no MedDRA subscription required. Practice is scoped to LLT-level terms, since the full hierarchy (PT, HLT, HLGT, SOC) is licensed content under MedDRA's subscriber terms.
• Enterprise — for organizations with their own active MedDRA subscription. Full SOC-through-LLT visibility, one login per associate, audit export, and 21 CFR Part 11 controls.

Both routes run against the live MedDRA dictionary — never a cached or reconstructed copy.
