First of all u were not mentioned for which reason you were taking codeine
Paracetamol and burden used for relief of fever
and pains, codeine will be prescribed by doctors advice , becoz it has high chances of addiction and abuse , so I recommend you to not use codeine unless otherwise your doctor asks you to take . Excessive intake of paracetamol causes liver damage
.you shouldn't take paracetamol more than 3 grams per day.
