Sometimes.
But you don't have the best medication for you. Side effects are depressing. Alendronate is causing stomach issues. Your doctors need to prescribe something different.
You might ask for a low dose of slowly infused Reclast. You get better bone benefit and bypass the stomach.
It is the best medication to follow Prolia.
I don't like the idea of these medications, but at your age I started Forteo. I was prepared for the worst but two years later I'm begging for extension and getting extended use.
If you quit with a Tscore of -4, especially after Prolia you are likely to fracture. A fracture will change your entire life in ways you can't imagine.
Quit the alendronate, but please don't quit. Demand better care.
