Tegrital (carabamazepine) is the best drug for complex partial seizure
. It is marketed by Novartis. In India, the name is Tegrital and in other countries, it is sold in the name of Tegretol. Both are same. Since, you have mentioned that your son had allergy, please consult your doctor before re-starting tegrital.
Other drugs useful in complex partial seizures are levetiracetam
