BONIVA is a prescription medication for the management of osteoporosis in postmenopausal women.

You should not take BONIVA if you have low blood calcium, cannot sit or stand for at least 60 minutes, have severe kidney disease, or are allergic to BONIVA. Stop taking BONIVA and tell your doctor right away if you experience difficult or painful swallowing, chest pain, or severe or continuing heartburn, as these may be signs of serious upper digestive problems. Follow the dosing instructions for once-monthly BONIVA carefully to lower the chance of these events occurring. Side effects may include diarrhea, pain in the arms or legs, or upset stomach. Tell your doctor and dentist about all the medicines you take. Tell them if you develop jaw problems (especially following a dental procedure) or severe bone, joint, and/or muscle pain. Your doctor may also recommend a calcium and vitamin D supplement.
