elizabeth1, your doctor may be correct. Knowing your health history might give them the best knowlege of what medication would work best for you.
Prolia is one of the most convenient an injection every six months.
It works in a way that is different than any of the other interventions. Prolia halts the body's normal process of bone acquisition. We have cells that break down the bone and cells that lay down fresh bone. Prolia is very effective at stopping the breakdown of bone, consequently you won't lay down any new bone. The increase in bone density will come from the collection of older fissured bone. This non-active bone less blood supply. While you are on Prolia for two years your fracture risk will be lower.
Unlike bisphosphonates the cells that break down bone are halted in the last stage of development. When you stop Prolia they will develope and be released with a vengeance on your bone. It is most common to take a bisphosphonate immediately following Prolia to try and cause those cell to die. The most effective of those bisphosphonates is Reclast. There are many articles and much discussion about how to stop Prolia safely.
There was a study indicating that taking Prolia with Forteo gives a better gain than either drug alone.
It isn't a popular option because it is difficult to get insurance coverage for two expensive medications.
You might want to use the search box for Prolia side effects.
In my opinion Tymlos and Forteo are safer pharmaceuticals that enhance the normal processes to build new vascularized bone.
I withhold a little panic I feel when anyone chooses Prolia. Wishing you the best luck.
