Whoa, whiplash here. I had to go back two years to refresh my memory. My original comment had been on dental issues. Here's an update. I've now been on Prolia for almost 4 years. I've not experienced hair loss since chemo. My hair grew back thinner, but the variables here that might cause that include aging (I'll be 70 in October) and 4 1/2 years on AI's. I used to have fairly thick hair so thinner is only obvious to me.
Recently I experienced some serious jaw pain so I visited my dentist. After special x-rays she concluded that all was well. She told me the jaw muscle ages like the rest of our body. My oncologist told me that jaw pain with Prolia is not uncommon and doesn't have to mean bone damage. It later occurred to me that I'd been taking collagen supplements for my knees and had recently cut the dosage in half. After resuming the prior dosage, my jaw issues improved significantly. I will transition off Prolia in December with Zometa and will discontinue AI's at the end of the year. Prolia has worked for me, so fingers crossed that next year my hair thickens, and my muscles and joints stop giving me fits.
