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.

Example Input: Two patients are described who developed sensory neuropathy after the ingestion of 30.6 and 114 g metronidazole respectively.

Example Input: Recommendations that may help prevent these adverse systemic effects in premature infants include: (1) avoidance of excess subconjunctival anesthetic doses, (2) preoperative administration of systemic atropine to minimize the oculocardiac reflex, (3) consideration of an analgesic agent to decrease the pain and exhaustion, and (4) cardiorespiratory monitoring in a hospital setting, with an intravenous line in place, at the time of treatment.
Example Output: non-adverse drug event

Example Input: Clearance rates of cerivastatin metabolites in a patient with cerivastatin-induced rhabdomyolysis.
