Alendronate and risidronate are not as potent as Reclast, which is a plus and a minus. They are bisphosphonates, like Reclast, but oral, not infused. The only caveat is that the former are hard to tolerate if you have GERD. I am hoping my more frequent lower dose Reclast can sort of mimic an oral regimen but it will avoid aggravating my GERD.
