Report suspected adverse drug reactions, even if you are unsure

Report suspected adverse drug reactions to your national pharmacovigilance system; proof of causation is not required.

In India, suspected adverse drug reactions can be reported to the Pharmacovigilance Programme of India (PvPI) through its reporting forms, helpline or app. You do not need to prove causation: a plausible temporal link, the drug and batch details, the outcome and any dechallenge or rechallenge are what matter.

Reports of unexpected reactions, reactions to new drugs and reactions in children and pregnancy are especially useful, and are the raw material for studies like the pharmacovigilance analyses above.

  • Report suspected reactions to PvPI even without proof of causation
  • Record drug, dose, batch, timing and outcome
  • Prioritise serious, unexpected and new-drug reactions
  • Note any improvement on stopping and any recurrence on restarting
