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

Example Input: Drug-induced aseptic meningitis (DIAM) is commonly seen with nonsteroidal anti-inflammatory drugs (NSAIDS), antibiotics (with TMP/SMX being the most frequently implicated), intravenous immunoglobulins and OKT3 antibodies.
Example Output: non-adverse drug event

Example Input: Successful desensitization to high-dose methotrexate after systemic anaphylaxis.
Example Output:
adverse drug event
