Case report: Pesticide-related methemoglobinemia: Tebufenozide and indoxacarb poisoning.
Background: Methemoglobinemia can be inherited or acquired. Acquired forms are more common due to drugs or poisonous substances that oxidize hemoglobin, and pesticide-related cases are notably rare.
Case presentation: We report a 69-year-old woman who ingested 30 mL of tebufenozide and indoxacarb and was asymptomatic for 3 h; however, the patient was admitted to the hospital after 8 h, unconscious, with tachypnea, cyanosis, and 61.9% methemoglobin. The patient was administered methylene blue, mechanically ventilated, and hemoperfused. Subsequently, the patient recovered and was discharged with no discomfort and with normal laboratory test results.
Conclusion: Tebufenozide and indoxacarb may cause methemoglobinemia, leading to cyanosis, unconsciousness, and respiratory failure; therefore, they should be handled with care in clinical practice.
