Evenity (romosozumab) injection is a sclerostin inhibitor used to treat osteoporosis in menopausal women to reduce the risk of bone fractures. It helps build new bone and reduce bone loss, improving bone mineral density and lowering the risk of spine fractures. Evenity works by blocking sclerostin, a protein that reduces bone formation. This increases bone building while decreasing bone breakdown, leading to increased bone density.
