Most overdoses come to no harm. For all overdoses (even common ones) it is good practice to refer to TOXBASE www.toxbase.org (password required). Print out a copy of the advice to put in the patient’s notes and follow the advice. If patient is unwell or you are not sure or a mixed overdose has been taken, discuss with a senior and contact the National Poisons Information Service (NPIS) on 0344 892 0111.
