Hi My child is 11-months old she has febrile seizure on jan 02nd. On jan 13th she has seizures without fever and doctor said she has seizure disorder and given the medication epitoin syrup 3 ml morning and evening . After taking the epitoin syrup also she has again seizures on Jan 18th with 2 episodes. Now they have given epitoin syrup 3.5 ml and levetiracetam 0.7 ml.
