Reclast is generally recommended after Prolia. Some people have adverse reactions to Reclast. Recommendation from a Stanford bone expert.

"I have prescribed a lot of Reclast (zoledronic acid), which to my knowledge is always administered in an infusion center, and not in a physician's office.My strong recommendation based on my knowledge of bisphosphonates (given that I helped to develop three of them, and treated 13,000 patients in phase 3 trials with them) is to have the infusion center dilute the 5 mg of zoledronic that comes in 100 mL of D5W into 500 mL of NS, and infuse the endodoc recnow 600 mL over 60 minutes. Making the drug more dilute and administering it more slowly significantly improves the renal safety for N-containing bisphosphonates.I also strongly recommend that the infusion nurses give the patient 650 mg of acetaminophen (Tylenol) at the time of the infusion, and that the patient take that same dose with dinner and at bedtime the day of the infusion, with all 3 meals and at bedtime the day after the infusion, and a final (7th) dose of acetaminophen with breakfast the 2nd morning after the infusion. These 8 doses total of Tylenol reduce the chance of a symptomatic APR (Acute Phase Reaction) from 22% to < 1%.Best, endodoc"
