The distribution and usage of Paraquat, a potent herbicide, remain unrestricted in many regions despite its high fatality rate and absence of a specific antidote. Paraquat mostly involves lungs but can also involve the kidneys and liver. Diagnostic challenges and a lack of available samples at presentation contribute to underreporting and limited awareness among healthcare providers, making paraquat poisoning a neglected toxicological emergency. Herein, we present a case of a 40-year-old male who presented to the emergency department on the fourth day after ingesting paraquat in a suicidal attempt. Upon presentation, he had erosion on the tongue and posterior pharyngeal wall, along with deranged renal function tests and elevated serum creatinine levels. The patient developed acute kidney injury, with serum creatinine levels rapidly rising from normal to 3.85 mg/dl, accompanied by a decrease in daily urine output. He was managed conservatively, and his hospital stay was uneventful.en-USOther
