    • Bisphosphonates
    • SERMs
    • Calcitonin
    • Forteo
    • Prolia
  28. Osteoporosis Treatment Algorithm
    •Bisphosphonates: first line for treatment unless contraindicated

    –Most patients prefer weekly dosing

    –Alendronate preferred due to generic availability

    –IV reserved for patients who cannot tolerate oral or with adherence issues (Zoledronic acid is least expensive and most convenient)

    •Second line:

    • –Raloxifene
    • – good for patients with breast cancer risk

    • –Teriparatide
    • – may be first line in patients with T-score less than -3.5

    –Desunomab?

    •Third line:

    • –Calcitonin
