%X This case describes a rare occurrence of high anion gap metabolic acidosis due to chronic acetaminophen (paracetamol) usage, which can be confirmed by measuring 5-oxoproline (pyroglutamate), an organic acid metabolite. As acetaminophen is an extremely common drug prescribed in both inpatient and outpatient settings, a high degree of clinical suspicion is required to isolate it as the aetiology for metabolic acidosis. Management includes discontinuation of acetaminophen use and at times the supplementation of oral bicarbonate. Metabolic acidosis due to a high anion gap is commonly described by the mnemonic 'MUDPILES' in daily practice. A newer mnemonic, 'GOLD MARK' is proposed to be a more inclusive tool to assist in determining the cause of high anion gap metabolic acidosis, especially with such cases being reported.
