Dear Patient, the prolia injection will have some stabilizing effect on your bone mass, i am assuming the bone mass got detected through special x ray (osteodensitometry) examination and the result showed that it is to low for your age group. The following serious adverse reactions are discussed: Hypocalcemia (low blood calcium) Osteonecrosis of the Jaw Atypical Subtrochanteric and Diaphyseal Femoral Fractures Infections Dermatologic Reactions Other possible side effects with Prolia in patients with postmenopausal osteoporosis are musculoskeletal pain, hypercholesterolemia, back pain, pain in extremity, and cystitis. Also back pain and constipation can occur. However, it is still advisable you give it a try since low bone mass can also lead to a lot of dangerous conditions like spine and femoral fractures. It is also important you take in enough calcium and vitamin D (ask your dotor about that). Hope this is helping you , if you have any clarificatons you can get back to me, if this was helpful please kindly rate my answer. Best regards
