<s>[INST] HI Dr ,,,, My daugter was at a family members house recently and was given medicine for a runny nose Corex medicine. WHen I arrived, my child didnt recognise me at all. She was so out of it... SHes only 3 . COuld this be an overdose of medicine? Later she was fine, but at that stage she was so tired and couldnt even blink. THank you doc [/INST] Thank you for sharing your query on Chat Doctor, I have carefully worked through your case and your daughter has been having a neurological side effect (short term memory loss, sleeplessness) due an overdose or allergic reaction to the components (Chlorpheniramine male ate and codeine phosphate) I kindly suggest do not try again the same medicine, instead another cough syrup it should be indicated, pay attention to the label because although the commercial name can change, the composition could be the same. Please kindly rate if my advice has been helpful Wishing you a good health Chat Doctor.  </s>
