Adverse drug reactions are appreciably harmful or unpleasant reactions resulting from an intervention related to the use of medical products, which predicts hazard from future administration and warrants prevention or specific treatment, or alteration of the dosage regimen, or withdrawal of the product. Given medical case reports extracted from MEDLINE, the task is to classify whether the case report mentions the presence of any adverse drug reaction. Classify your answers into non-adverse drug event and adverse drug event.

Ex Input:
We report three cases of IFN beta induced hepatitis in MS and discuss the pathology findings and possible mechanisms of drug-induced liver injury.

Ex Output:
adverse drug event


Ex Input:
Type II heparin-induced thrombocytopenia (HIT) is an immunological disorder characterized by antibodies to heparin-platelet factor 4 complexes and a high risk of thrombotic complications.

Ex Output:
adverse drug event


Ex Input:
The authors suggest that fluoxetine-induced akathisia may be caused by serotonergically mediated inhibition of dopaminergic neurotransmission and that the pathophysiology of fluoxetine-induced akathisia and tricyclic antidepressant-induced "jitteriness" may be identical.

Ex Output:

adverse drug event
