Background: Organophosphorus (OP) poisoning is a major health problem all over the world, particularly in the developing countries. Aim: The present study aims to explore the clinical and epidemiological features found in patients presenting with OP poisoning. Materials and Methods: A 1-year cross-sectional study was conducted on patients presenting with clinical features of OP poisoning in a tertiary care medical college. Results: A total of 968 patients presented during the study period. Poisoning with suicidal intent (82.02%) was more common than the accidental one (17.98%). Majority of the patients were housewives (42%) followed by farmers, shopkeepers, laborers, students. Methyl parathion was the most common poison consumed by the patients (35.74%) followed by diazinon, chlorpyriphos, dimicron. Nausea and vomiting (85.02%) was the most common symptom while miosis was the most common sign observed in 91.94% patients. A total of 56 patients of OP poisoning died (5.78%) with respiratory failure being the primary cause of death followed by CNS depression, cardiac arrest, and septicaemia. Conclusion: The present study showed that majority of the patients were of young age with females outnumbering males. Poisoning with suicidal intent was more common than accidental.
