51 patients diagnosed with chronic pain or fibromyalgia syndrome who were using duloxetine for at least 3 months and age and sex matched 51 healthy individuals were recruited for this cross-sectional study. Bone mineral density of both groups were measured by dual energy x ray absorbsiometry(DXA), bone biochemical markers, serum calcium, and vitamin D levels were investigated.
The aim of the study was to determine the effect of duloxetine as monotherapy on biochemical markers and bone mineral density.
