@serious. My primary care doctor told me that I could take Fosamax for 5 years and then I was done. I could not take it again.

My endocrinologist told me this actually not true. A person can take Fosamax for up to about 5 years and then can take that med again - or a different one from the same classification - a year or two later. I was told this by an orthopedic surgeon and my endocrinologist, both at Mayo Clinic.

I had a bone density scan and blood tests prior to starting on Evenity last Fall, 2023, as I needed medication to "build" bone. Despite the gains I made on Fosamax I lost bone mass because I had a radiation therapy (a known side effect of radiation therapy to the pelvic area in particular where I had it for endometrial cancer).
