Hey Larry, I don't have any experience with the combo, or dilantin at all. But I was drawn to the thread because it was one of the meds my mom took. But then she took all kinds.
Isn't that a seizure med? My mom had epilepsy. I thought that one she took was for that. My mom is no longer living, or I' ask her. Becuase she abused all sorts of meds, and was taking that.
But you can look it up on the net. In a search engine. You should find some info.
Why are you asking? If I may ask????
Have a good day, Love, Becky
