Summary

Background: Methotrexate is a widely used immunosuppressant with good efficacy and cost-effectiveness. However, one of the drawbacks of methotrexate has been toxicity due to accidental overdose. During the COVID pandemic, there was an alarming increase in the number of patients with methotrexate toxicity which prompted us to do this study. Objective: To evaluate the clinical features and contributing factors in patients presenting with methotrexate toxicity. Materials and Methods: A detailed evaluation of the clinical features, laboratory indices, contributing factors, and outcomes of the patients presenting with methotrexate toxicity was analyzed. Results: A total of 19 cases were seen during the study period. All of the patients had oral mucositis and several developed cutaneous ulcerations. Laboratory abnormalities included cytopenia, transaminitis, and renal impairment. While sixteen patients recovered successfully, three people died as a result of delays in medical assistance. In addition to comorbidities, pandemic-induced restrictions played a major role in patients accidentally overdosing with methotrexate. Conclusion: This study highlights the fact that even low-dose methotrexate taken incorrectly can result in a lethal outcome, which is preventable.
