A 55-year-old man was hosipitalized with hypertension, diabetes and hyperlipemia. He had no history of drug hypersensitivity in the past. The patient was treated with intravenous infusion of sodium ferulate 0.15g. 5 minutes later, he suddenly developed restless, sweat, paleness, cold limbs, diminished heart sounds and undetected BP, which was considered in association with allergy of sodium ferulate. The liquid was withdrawn immediately and his BP was raised to 110-130/60-80mmHg after receiving dopamine 20mg, dexamethasone 10mg and adrenaline 1mg.
