Normochromic normocytic anemia in a postmenopausal woman with severe osteoporosis treated with intermittent parathyroid hormone.

Intermittent exogenous parathyroid hormone (PTH) is a potent osteoanabolic agent used for the treatment of severe osteoporosis. Two molecules of recombinant PTH are commercially available: the full-length PTH (PTH 1-84) and teriparatide (PTH 1-34). We present the first report of PTH-induced mild, asymptomatic, normochromic normocytic anemia in a postmenopausal woman treated sequentially with PTH 1-84 and PTH 1-34.
