Zoledronic acid
"I am 41 with Crohn's disease causing my lack of vitamin absorb. I had my monthly entyvio infusion and right after my first reclast infusion just yesterday.  I was just fine until about 5 hours after when I started having diarrhea. It later turned into severe watery diarrhea shooting out into my Ostomy, chills, sweating, fever, aches, and weakness. I was told it may happen but was hoping not to me. If this helps me a few days of this is worth it and I will do it again. Like on Harry Potter "growing bones is a nasty business!" Lol"
