This handout is for osteoporosis & fragility-fracture prevention (dxa/frax → treat-to-target). Your care team identified this based on: postmenopausal woman or man ≥ 50 — screening / risk-assessment visit (bhof 2022 pmid 35478046).
Other reasons your team may use this plan: prior low-trauma (fragility) hip or clinical/morphometric vertebral fracture — clinical osteoporosis regardless of bmd (endo soc 2019 pmid 30907953); chronic glucocorticoid (≥ 2.5–7.5 mg prednisone-equivalent ≥ 3 months) — glucocorticoid-induced osteoporosis surveillance (aace/ace 2020 pmid 33577971); incidental vertebral fracture / low bone density on imaging (vfa, ct, plain film) (bhof 2022 pmid 35478046).
Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.
| Medication | Starting dose | How | When | What it does |
|---|---|---|---|---|
| cholecalciferol (vitamin D3) | 800–2000 IU/day, titrate to 25-OH-D ≥ 30 ng/mL | PO | once daily | BHOF 2022 (PMID 35478046) — adjunct (NOT monotherapy); replete BEFORE a potent antiresorptive to avoid hypocalcaemia; Bischoff-Ferrari fall RR 0.81 (0.71–0.92) in deficient (PMID 19797342) |
| calcium carbonate (diet-first) | 500–600 mg elemental BID with meals; total diet + supplement ~1000–1200 mg/day | PO | BID with meals | BHOF 2022 (PMID 35478046) — adequate calcium with vitamin D underpins every antifracture regimen |
| treat the identified secondary cause first (parathyroidectomy / control hyperthyroidism / replace gonadal axis / gluten-free diet / taper glucocorticoid / treat myeloma) | — | — | — | Endo Soc 2019 (PMID 30907953) — a reversible secondary cause is treated before (or with) the antiresorptive; route primary HPT to endo.hyperparathyroidism.v1 |
Plan: Osteoporosis treat-to-target ladder — foundation/secondary-cause → HIGH-risk antiresorptive-first → VERY-HIGH-risk anabolic-first → directional anabolic→antiresorptive sequencing + denosumab transition → SERM/MHT → drug-holiday logic (Endo Soc 2019 PMID 30907953; AACE/ACE 2020 PMID 33577971; ASBMR/BHOF 2024 PMID 39073912)
Use these zones to know what to do based on how you feel.

Drug-holiday logic: reassess oral bisphosphonate at ~5 years / IV zoledronate at ~3 years (FLEX PMID 17190893) — continue if still high/very-high risk, holiday if risk reduced; denosumab has NO holiday (transition to a bisphosphonate on stopping). Re-stratify very-high-risk patients; sustain calcium/vitamin D, weight-bearing/resistance exercise, smoking/alcohol counselling and a falls-prevention programme; lifelong surveillance — the diagnosis persists even if T-score rises above −2.5 (BHOF 2022 PMID 35478046; AACE/ACE 2020 PMID 33577971)
