Hello glad you stopped by. I am glad your son is being weened off of Depakote(Valporic Acid). I used to be on it when i was 12 and was removed from it because the drug can cause serious damage to the liver in your system. The weening process is a tough one for anyone child or adult because your system will be altered for at least a month. Usually when you reduce the drug you have been taking and begin taking a new drug you can suffer from side effects from both drugs. The only thing to do is continue until he is no longer taking the old drug. Next, is to start a diary with the new drug of when to take the drug, what is the dosage, what time to take it. Also how you are feeling before taking the meds and after the meds. The information gathered will be helpful the next time you speak to the doctor. Try going to this website; www.epilepsy.com It has a lot of good information. Take care.
