Hi carer with mother with MM --I was on Aridia for almost 2 years and only went off it when I heard about the osteonecrosis of the jaw problems which were beginning to show up around the world. Although it took longer to recieve I felt that it was safer than Zometa. I experienced NO side effects, however after being on it once a month for 14 months I was hit by a car while crossing the road. Everyone in oncology was amazed that I did not suffer any broken bones as a result of the accident given that I have MM lesions on all the bones in my body! Given that I was thrown in the air and over the top of the cars bonnet before landing with a thud on the roadway, the only thing we could put it down to was that the Aridia had actually STRENGTHENED my bones! So, although I have stopped taking it I often wonder whether I'm doing the right thing. Revlimid has been working wonders for me and my latest skeletal survey shows no NEW lesions in over a year so I'm hoping that my bones are still as strong as they were at the time of the accident. Needless to say, I think Aredia is GREAT! Best wishes, Cath
