Hello,
Thank you for asking at HCM.
I went through your history and would like to make suggestions for your son as follows:
1. Although an overdose, I would think an approximate double dose of
paracetamol (Calpol) would not cause any serious consequences. Of course, grave consequences can occur after a very large dose of paracetamol.
2. Please observe your son for any symptoms like
nausea,
vomiting,
abdominal pain,
lethargy, uneasiness, etc. Should any of above symptom appear, please consult a doctor and get him examined by him/her.
3. In pediatrics, doses of drugs are based on weight of the child, not on age of the child. So in future, please do not give any drug without consulting a doctor. Dosing of a drug based on labels on the medicine can be harmful.
Hope above suggestions will be helpful to you.
Wish your son a safe outcome and a good health ahead.
Thank you & Regards.
