Medications can and often do cause vertigo issues and a friend dealt with this while taking gabapentin....she's off the drug now and doing good. Finally went to Grape Seed Extract and it's been wel over 8 yrs for her and she's WAS a major allopathic medicine person. Also, Grape Seed Extract cross the blood brain barrier and gives us more protection overall. I've been taking it for close to 25 yrs.
