Hi lkawausn,

Welcome to the forum! Vimpat and grapefruit don't go together very good. The enzymes in the grapefruit can mess up the vimpat and many other sz. meds. I know that since I've been on vimpat in Aug. 2010 I found out that grapefruit and grapefruit juice will mess up the vimpat so the drug will not work and it overloads the liver which can cause an overdose for a person and lead to death. It was the same thing for tegretol and trileptal also. I hope I have been of some help and May God Bless You!
