Topamax (topiramate) addto dilantin + med change then increased multiple seizures er dr said dilantin levels are toxic. caused by topamax (topiramate)? when seizures stop?

Me no understand: Your statement sounds like Morse Code to me. Some of it I get but maybe you can restate it a bit more calmly. If Dilantin were added to Topamax (topiramate) then, yes toxic levels of Dilantin could occur. If other way around then, we'd expect levels of Topamax (topiramate) to decrease not Dilantin increase. Sounds like you need to check in with your neurologist for a "realignment" of some sort with your meds.
