If you take depakote 500mg EC for a very mild seizure disorder and take 1 every other day then stop for 4 days is it possible to have a seizure or is it still in your system enough to control it?

I hope you didn't decide to taper off the medication without medical supervision. There may or may not be enought med left in your system to control a seizure, but probably not. If you're at risk for seizure you shouldn't be discontinuing your seizure med :-)
