I had my last of 3 Reclast infusions in 2015.The infusions themselves are not a problem—just 15 minutes each. I had no obvious side effects. However, I had a dental implant placed in 2012, and waited 6 months before starting Reclast in early 2013. This past July the implant failed and eventually just fell out. My dentist is sure the Reclast was the cause. I am hesitant to start Prolia now, even though it is not a bisphosphonate.
