yesterday I was admitted into the hospital because my body was trembling. Stiffness in the body, chills, shaking and headache. A blood test was taken and the doctor said " your level is good, at 100." But your phenytoin level is a little high at 22. I'm taking a daily dose of Phenytoin 100mg 6x with Valproic Acid 250mg 12x. Before I went to generic I was on the name brand Dilantin same dose and Depakote that were 500mg 6x daily. Am I taking to much Valproic Acid.
