My husband had a few vertigo attacks with Gem-Abraxane. First dose brought on an attack and that sorted itself out in a few days with medication. Thereafter, he had a few giddy spells but not severe. However 6 months later, he had a prolonged attack of 3 weeks. That also stopped with medication. So far no other attacks. But it seems to be a side effect of the chemo for him and when his red blood cells are low. We try to make sure he has some sugar in him daily (like a small slice of cake, fruit, raisins etc) rather than keep away from sugary stuff completely.
