Can some one tell me about osteoporosis medication side effects?

Upset stomach: Generally osteoporosis medicines are well tolerated. The most commonly used are bisphosphonates taken by mouth. They most commonly cause heartburn. Intravenous bisphosphonates cause fever and muscle aches for 1-2 days in 30-40% of patients. Very rarely bisphosphonates are associated with jaw problems and fractures of the mid thigh bone. Teriparatide may cause nausea and muscle cramps.
