Ibandronate
Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Ibandronate is a bisphosphonate used for treatment and prevention of postmenopausal osteoporosis. Oral absorption is extremely low and is substantially reduced by food, beverages other than plain water, calcium, magnesium, iron, antacids, and vitamins, so strict fasting administration and mineral separation are essential.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Ibandronate is a bisphosphonate used for treatment and prevention of postmenopausal osteoporosis. NutriStack rates the supporting evidence as strong. Common adult dosing is Oral: 150 mg once monthly, taken first thing in the morning with plain water at least 60 minutes before food, drink, supplements, or other medications; older daily regimens used 2.5 mg daily. Intravenous: 3 mg every 3 months in appropriate patients., though a prescriber sets the actual dose. This profile indexes 3 sources.
The bottom line
Evidence rating strong. Most-documented uses: treatment of postmenopausal osteoporosis, prevention of postmenopausal osteoporosis, increased bone mineral density. 3 sources indexed (2004–2026), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Ibandronate binds hydroxyapatite at bone resorption surfaces and is taken up by osteoclasts during bone breakdown. As a nitrogen-containing bisphosphonate, it inhibits farnesyl pyrophosphate synthase in the mevalonate pathway, impairing osteoclast function and survival. Reduced osteoclast-mediated resorption increases bone mineral density and lowers vertebral fracture risk.1,3
Dosing & protocol.
Take oral ibandronate after an overnight fast with 6 to 8 ounces of plain water only. Remain upright and avoid food, beverages, supplements, and other medications for at least 60 minutes.
