Injections of certain osteoporosis drugs, such as Boniva, Forteo and Prolia, can be administered every six months as an alternative to oral medications; these injections reduce the risk of fractures, according to the National Osteoporosis Foundation. Bisphosphonates like Boniva, for example, slow the rate of bone loss due to osteoporosis.
Many patients prefer to receive injections for osteoporosis rather than take oral medications. Injections are delivered less frequently (usually twice a year), so patients do not have to remember to take a pill every day or once a week. Injections are given in different dosage ranges based on whether they are intended to treat or prevent osteoporosis.
