I have been taking natural medicine called phenocane for years. I am now taking Topamax for migraines and had not taken them together until today. Actually take 25 mg at night of Topamax and took the phenocane this morning with my vitamins. Had a dizzy spell at work and had to seek medical attention as I work in an industrial area, can t be walking around dizzy. Had an EKG, perfect, everything good. Dr never heard of phenocane so I was just curious as to what you on your sight knew. Thanks! :)
