Is taking too many codeine phosphate dangerous?
Of course, yes! It WILL (in large dose) cause death! Codeine phosphate, in pure form, without addition of eg paracetamol, is usually use for control of pain and severe unproductive cough. It is an opiate. These are the symptoms of overdosed – from mild to severe – giddiness, vomit, nausea, visual disturbance, dry mouth, difficulty passing urine, headache, tinnitus, tremors, insomnia, drowsiness, change in mental status, weakness, seizures, difficulty to breath, and eventually death. Care to explain why are you asking this question?
