Is Cepodem 100 a very strong antibiotic for a 3 year old

Is Cepodem 100 a very strong antibiotic for a 3 year old?

My daughter is suffering from a fever and the recent blood test reports have indicated a slight infection which the doctor says is nothing serious. She has been recommended Cepodem 100 for seven days. Her weight is 29 lb and I am giving 3 ml of the antibiotic twice a day. Is the antibiotic too strong for her?
