Boniva vs. Prolia
See how Boniva and Prolia compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Boniva is a once-monthly oral tablet, while Prolia is an injection given by a healthcare provider once every 6 months.
Boniva is approved only for postmenopausal women, while Prolia covers postmenopausal women, men, and people with steroid- or cancer-treatment-related bone loss.
Both drugs carry warnings for osteonecrosis of the jaw and atypical femoral fractures, but Prolia also carries a boxed warning for severe hypocalcemia in advanced kidney disease.
Boniva vs. Prolia Drug Summary
Boniva
Boniva (ibandronate) is a nitrogen-containing bisphosphonate used to treat and prevent osteoporosis in postmenopausal women. It comes as a tablet taken once a month on an empty stomach, and the person must stay upright for 60 minutes afterward to avoid esophageal irritation.
Prolia
Prolia (denosumab) is a RANK ligand inhibitor given as an injection every 6 months in a doctor's office or clinic. It treats osteoporosis in postmenopausal women, men, and people at high fracture risk from steroid use, prostate cancer therapy, or breast cancer therapy.

Boniva vs. Prolia Pros and Cons
Boniva
Boniva offers a simple, self-administered pill taken once a month, but it requires a strict routine around timing and posture to avoid esophageal irritation. Its FDA approval is limited to postmenopausal women, so it is not an option for men or for steroid-related bone loss.
Pros
Self-administered tablet, no clinic visit needed
Long track record, FDA-approved since 2003
Approved for prevention before major bone loss occurs
Lower monthly list price ($155 to $285)
Cons
Must be taken on an empty stomach and upright for 60 minutes
Not approved for men or glucocorticoid-induced osteoporosis
Only covers postmenopausal women
Common GI side effects like dyspepsia and diarrhea
Prolia
Prolia covers a much broader group of patients, including men and people with cancer-treatment-related bone loss, and only needs to be given twice a year. It requires in-office administration and carries a boxed warning for severe hypocalcemia in patients with advanced kidney disease.
Pros
Only 2 doses per year instead of a monthly pill
Approved for men and multiple bone-loss conditions
No dosing-related esophageal or posture restrictions
Given by a healthcare professional, reducing dosing errors
Cons
Requires an in-office visit every 6 months
Boxed warning for severe hypocalcemia in advanced kidney disease
Risk of rebound vertebral fractures if stopped without follow-up therapy
Higher list price of $1,600 to $2,000 per injection
