Standard Prolia Dosing Schedule
Prolia (denosumab) is injected subcutaneously every 6 months to treat osteoporosis and increase bone density in postmenopausal women, men at high risk for fractures, or patients with glucocorticoid-induced osteoporosis.1
Why Every 6 Months?
This schedule stems from clinical trials showing sustained bone mineral density gains with biannual dosing. Prolia targets RANKL to inhibit osteoclasts, providing long-lasting effects that align with its 6-month half-life and pharmacokinetics.1
How Is the Injection Given?
A healthcare provider administers a 60 mg dose in the thigh, abdomen, or upper arm using a prefilled syringe. Patients should receive calcium and vitamin D supplements daily to prevent hypocalcemia.1
What If a Dose Is Missed?
If delayed beyond 6 months, administer as soon as possible, then resume the 6-month schedule. No double-dosing.1
Common Side Effects Patients Report
Back pain, muscle pain, high cholesterol, and bladder infections occur frequently. Serious risks include jaw osteonecrosis, atypical femur fractures, and severe hypocalcemia—monitor blood calcium levels.1
Prolia vs. Other Bone Density Treatments
| Treatment | Dosing Frequency | Key Difference |
|-----------|------------------|---------------|
| Prolia | Every 6 months | Targets RANKL; no oral option |
| Fosamax (alendronate) | Weekly oral | Bisphosphonate; daily calcium needed |
| Forteo (teriparatide) | Daily self-injection | Anabolic; 2-year max use |
| Evenity (romosozumab) | Monthly injections for 12 months | Dual action; cardiovascular risks1 |
When Does Treatment Stop?
Discontinue after 3-5 years if benefits outweigh risks; rapid bone loss can follow cessation, sometimes requiring bisphosphonates.1
Cost and Access
A single 60 mg dose costs $1,500-$2,000 without insurance; Medicare Part B covers injections.4
