Five myths about adverse reaction reporting

“I don’t need to report that.” — a sentence that can prove costly in pharmacovigilance. Five persistent assumptions and what actually applies.

01

Myth 1: Only serious cases are reportable

Both are reportable. The difference lies in the deadline: serious suspected adverse reactions must be reported within 15 days, non-serious ones within 90 days. GVP Module VI distinguishes between the deadlines, not the obligation.

02

Myth 2: This only concerns the pharmacovigilance department

The clock starts on the day anyone in the company becomes aware of the case — not only when the case reaches the specialist department. This makes sales, field force, customer service and reception part of the pharmacovigilance system.

The practical effect is unwelcome: a case that sits with the field force for two weeks arrives in the specialist department with half of its deadline already used up.

03

Myth 3: Without a confirmed diagnosis it is not a case

Four minimum criteria are sufficient for a reportable case: an identifiable patient, an identifiable reporter, a suspected adverse reaction and a medicinal product.

A confirmed diagnosis is not one of them. What matters is the suspicion of a possible causal relationship — not proof of it.

04

Myth 4: Known reactions do not need to be reported individually

Reactions already listed in the product information are also reported as individual cases. The frequency of a known reaction is itself safety-relevant information — and it can only be evaluated if the cases are available.

05

Myth 5: Incomplete information makes the report invalid

If the four minimum criteria are present, the report is valid. Missing details are added through follow-up.

The error in the other direction is the more costly one: holding back a case until it is complete and letting the deadline pass in the meantime.

06

Why this is more than detailed knowledge

Pharmacovigilance compliance begins with a correct understanding of these basics — among everyone who has customer contact, not only at the next audit. This is precisely why training for employees outside the specialist department is regularly examined during inspections.
