This article states that there have been reports of kidney problems with patients taking thalidomide and zoledronic acid at the same time.

Has anyone reading who is undergoing both therapies had kidney problems?  David 

"Previous case reports suggested that multiple myeloma patients
receiving thalidomide for disease control along with zoledronic acid
for bone maintenance faced higher risks of renal impairment than
patients receiving other treatments, the authors explain.

Mean maximal plasma concentrations and mean plasma concentrations
over 24 hours for zoledronic acid did not differ significantly when the
drug was administered with or without thalidomide, the authors report."
