I am taking st. johns wort 300mg at night and am considering taking depakote125mg. I was recently prescribed it for bipolar disorder, but im hesitant to take it, especially combining the two. My psychiatrist says that I probably wont have any problems, but shes also not a pharmacists or herbal health "master"; so i have been looking into it myself. Like Jikan mentioned in his answer it seems they both work in different ways, depakote is an anti seizure med while SJW acts as a ssri, so its unlikely that they will interact, but yeah its scary to just try it. Did you ever decide to try them both at the same time?
Namaste,
Taking St. Johns' Wort with Depakote would not, in all probability, cause you any significant problems, but remember that St. Johns' Wort is used to treat depression, whereas Depakote is a mood stabilizer.
There is a very minor possibility that St. John's Wort would place in you in a manic state and that's not where you want to be.
You should not take any supplements or combine medications without your doctors' approval. If you have an appointment with him/her on the 28th, I think you can wait until then before making any decisions.
