My brother got a lack of oxygen during birth, which led to his mental disability, he is 12 years old now. He suffers from epileptic seizures too. He takes tegrital (carbamazepine) and phenotal 60 (phenobarbitone ). Phenotal is no longer available in our country and with taking other brands of the drug, his seizure attacks wasn't controlled, the serum level of phenobarbitone was 34.96 umol/l which is below the therapeutic range, so his doctor decided to switch his medication to epanutin (phenytoin sodium) so we stopped phenobarbitone gradually within 5 days and started to give him phenytoin. That was last month. He is tired and upset most of the time and he has sleep disturbances. He had tonsillitis in the last 2 days. Today we were in the car, suddenly his face paled and he closed his eyes and then keep closing and opening them, but he talked to me, I thought that his blood pressure went down because he didn't have breakfast. When we got home he didn't remember that we were in the car, is this a type of absence seizure? Is that related to phenytoin? Is it normal when starting using phenytoin? Thank you.
