I’m 70, just had my second infusion. Other than the 2 day flu the first time, I’ve had no side effects that I notice. However I happened to have a previously unplanned CT scan with contrast just 7 days after the second infusion - so they ran kidney function bloodwork before the scan. My eGFR dropped from 80 to 49 and my creatinine is now 1.2. It is believed the cause was the Reclast, but it’s expected to be a temporary change. I will have another blood draw in a week and a half - the hope is that the kidney function will recover to its normal level.
So the one caution I would have is if your kidney function is low already you would want to discuss the implications of Reclast with your doctor.
Reclast has worked for me, I’m no longer in osteoporosis (my lowest level was -2.9 before tx). But I would not risk my kidneys for it - if my eGFR doesn’t rise back up I won’t be taking Reclast again (3 infusions were recommended).
