These medications both require they be taken on an empty stomach at least 2 hours after eating and 1 hour before eating. With 2 doses of zytiga/day, these two 3 hour windows remove 6 hours every day from Fosamax dosing. Taking Fosamax at the same time as the before-breakfast zytiga would greatly simply these procedures on the one day a week when Fosamax is dosed! Can I?
