@suslirsdlmayo72 most people do fine on Reclast. I am sorry for those who suffer on it and don't mean disrespect. If you are sensitive, ask your doctor if you can have a lower dose, IV hydration and a slower infusion (one hour). Take tylenol. I believe 40% have a flu like reaction to the first dose and then that tends not to happen again, according to what I have read.

If you have been on Prolia, not sure what choice you have to avoid rebound. You could take oral Fosamax (alendronate) but some say it isn't as potent against rebound from Prolia. One person posted about doing Evenity after Prolia but not enough info on that yet and you would have to do Reclast of Fosamax after that!

I am sensitive to just about everything and have handled Reclast well but at a lower dose with the above protocol. Reclast has been around for 22+ years.
