Dear Md Arshad thanks for your question She is having epilepsy and is presently on Zenoxa (oxcarbamazepine), Epilex chrono (sodium valporate) and etilaam. She is taking correct prescription for epilepsy. oxcarbamazepine is a good Anti epileptic drug (AED) and with negligible side effects apart from a little high cost. Epilex is also one of best AED and a broad spectrum drug. It is a very safe drug but in a few patients during start of therapy Nausea, vomiting may be seen. But don t worry with time the side effect will go because the dose she is taking in not very high and she will start tolerating this dose. Etizolam is given usually to relieve anxiety in patients and it induces calmness in patient. So be assured nausea will decrease with time till then you can give her any OTC antacid medicines. thanks and take care hope i solved your query.
