Osteoporosis Treatment Guidelines

First-Line Pharmacologic Treatment

• The American College of Physicians recommends oral bisphosphonates, such as alendronate or risedronate, as the first-line treatment for osteoporosis in postmenopausal women and men, with strong evidence for reducing hip, vertebral, and nonvertebral fractures 1, 2

Pharmacologic Treatment Options

• Alendronate is recommended at a dose of 70 mg once weekly or 10 mg daily 2
• Risedronate is recommended at a dose of 35 mg once weekly, 5 mg daily, 75 mg on two consecutive days per month, or 150 mg monthly 2
• Zoledronic acid is recommended at a dose of 5 mg IV annually for patients unable to tolerate oral bisphosphonates 2

Treatment Duration and Drug Holidays

• The treatment duration for oral bisphosphonates is typically 5 years, after which fracture risk must be reassessed to determine whether to continue therapy or initiate a drug holiday 2
• Drug holidays are appropriate for low-to-moderate risk patients after 3-5 years of oral bisphosphonates or 3 years of IV bisphosphonates 2, 3

Second-Line Treatment

• Denosumab 60 mg subcutaneously every 6 months is recommended for patients with contraindications to bisphosphonates or who experience adverse effects, with moderate-certainty evidence for postmenopausal women and low-certainty evidence for men 2

Glucocorticoid-Induced Osteoporosis (GIOP)

• The American College of Rheumatology recommends that all adults and children receive initial clinical fracture risk assessment within 6 months of initiating long-term glucocorticoid treatment (≥3 months) 4, 5
• Oral bisphosphonates are strongly recommended for adults ≥40 years at moderate-to-high risk, with a treatment hierarchy that includes IV bisphosphonates, teriparatide, denosumab, and raloxifene 6

Essential Adjunctive Measures

• All patients must receive adequate calcium (1000-1200 mg daily) and vitamin D (800-1000 IU daily) supplementation throughout osteoporosis treatment, as recommended by the American College of Physicians 1, 6, 2
• Lifestyle modifications, such as weight-bearing or resistance training exercise, smoking cessation, limiting alcohol to 1-2 drinks/day, and maintaining weight in the recommended range, are strongly recommended 6

Cost Considerations

• Generic bisphosphonates should be prescribed whenever possible rather than brand-name medications, as they are significantly less expensive while maintaining equivalent efficacy, as recommended by the Praxis Medical Insights 2
