-Major fracture risk > 20%
What is first-line treatment for osteoporosis?
Bisphosphonates
-Alendronate
-Ibandronate
-Risedronate
-Zoledronic acid
What are rare but serious concerns of bisphosphonates?

What are counseling points on the administration of bisphosphonates?
Should be taken with 6-8 oz of water at least 30-60 min before eating or drinking
Should remain upright for at least 30 min after being administered an oral dose

Who would be a candidate for romosozumab therapy?
One of the following:
-Multiple fragility fractures
-High risk of fracture who cannot tolerate any other therapies
-Other therapies have failed (fracture with loss of BMD despite adherence to therapy)
Which agents require antiresorptive therapy after treatment discontinuation?
-Romosozumab
-Teriparatide/abaloparatide
How often should DEXA be repeated after osteoporosis diagnosis?
Yearly (some insurances will only cover every 2 years if not on therapy)
What is the only intervention shown to reduce progression of OA?
Nonpharmacologic interventions (weight loss, low-impact exercise, PT, support braces)
