Hi,
I would certainly discuss your change of reaction to Zometa with your consultant for their advice as to whether to continue with the treatment in its current format.
When I first received Zometa in 2010, I was hardly given any IV fluids prior or after Zometa which did contribute to certain side effects of dizziness and headache for a two to three days after the infusion. However when I changed hospitals in 2011, the nurses always ensured sufficient IV fluids were administered at the time of the Zometa infusion which certainly helped with the side effects. I was also advised to drink plenty of fluids for the days around Zometa. You might ask your consultant as to whether slowing down the rate of infusion from 15 minutes to 30 minutes might help reduce any side effects.
Regards
Jan
