my son is 2 years and 3 months old and we have given zental 10 ml as dosage as per doctor advised but he suffers from worm again .only 1.5 months have past.what shall to do

A. 10 ML you have given in one go or twice within the gap of 14 days because for a small child 5ML in the first night and five after 14 should be given to the child I hope you’ve given it this way if you’re facing this issue and you need to consult your doctor because the deworming is not suggested before six months
