Osteoporosis
Primary prevention of osteoporosis starts in childhood. Patients require adequate calcium intake, vitamin D intake, and weight-bearing exercise. Patients should be counseled on smoking cessation and moderated alcohol intake. Patients who have disorders or who take medications that can cause or accelerate bone loss should receive calcium and vitamin D supplementation
Medications known to cause or accelerate bone loss
Corticosteroids - Prednisone (≥ 5 mg/d for ≥ 3 mo)23
Anticonvulsants - Phenytoin, barbiturates, carbamazepine (These agents are associated with treatment-induced vitamin D deficiency.)
Heparin (long-term)
Chemotherapeutic/transplant drugs - Cyclosporine, tacrolimus, platinum compounds, cyclophosphamide, ifosfamide, methotrexate
Hormonal/endocrine therapies - Gonadotropin-releasing hormone (GnRH) agonists, luteinizing hormone-releasing hormone (LHRH) analogs, depomedroxyprogesterone, excessive thyroid supplementation
