@gigi05 What would you like to know? It is Zolodronic Acid, IV infusion that takes about 30 minutes. It is one of those drugs that is associated with jaw fractures. I could swear my primary dr said it wasn't one of those when I started it 2 years ago. I haven't had any reactions or side effects that I was conscious of. But have realized my issues with swallowing and GERD started about the same time I started the Zolodronic.
