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.

Input: Consider Input: Patients in whom CSC develops while using corticosteroid inhalers or nasal sprays should be alerted to the possible relationship between CSC and these agents.

Input: Consider Input: Transthoracic or better transoesophageal echo-cardiography and Doppler are by far the most accurate diagnostic tools that can entirely replace angiographic assessment.

Output: non-adverse drug event


Input: Consider Input: Within 3 weeks of beginning continuous daily isoniazid and rifampin therapy for pulmonary tuberculosis, a patient developed acute renal failure.
