Eptoin is the brand name; the name of the medicine is phenytoin sodium. Similarly Tegrital contains carbamazepine. I suggest you buy the Epsolin brand of phenytoin sodium made by Cadila Healthcare that costs Rs. 70 for 100 tablets along with required quantity of Tegrital and take them with you to USA. If more supplies are needed your family member/friend can just mail the same to you in America. Insurance will not solve your problem because of exclusion clause for disorders that existed before a cover is taken out.
