We must always live with some measure of
uncertainty.

What is Pharmacovigilance?
WHO definition:
The science and activities relating to the
detection, assessment, understanding
and prevention of adverse effects or any
other drug-related problem.
This applies throughout the life-cycle of a medicine equally
to the pre-approval stage as to the post-approval.

What is the scope of pharmacovigilance?
improve patient care and safety in relation to the use of
medicines, and all medical and paramedical interventions,
improve public health and safety in relation to the use of
medicines,
contribute to the assessment of benefit, harm, effectiveness
and risk of medicines, encouraging their safe, rational and more
effective (including cost-effective) use, and
promote understanding, education and clinical training in
pharmacovigilance and its effective communication to the public
