Hi welcome to Health care magic forum, One should not take self decissions regarding treatment of kids. For children or adults there should be at least 4to 5 hours of gap between giving antipyretics, if there is more fever
in between sponging with ice water, if there is rigour with ordinary water.
Only anti pyretics wont solve the problem, some more drugs are to be given . Children should always be taken to doctor after first aid
at home, it not the sole treatment.
Any how your kid is safe till now , means no harm but should not be repeated. When the drugs effect ceases he may get fever again, so i advise you to consult a pediatrition for diagnosis and treatment . thanks for calling.
