[Rise in serum creatinine under the androgen fluoxymesterone in chronic renal disease (author's transl)]

Eight men with chronic renal disease in the stage of compensated retention were given high doses of the androgen fluoxymesterone (40 mg/m2/day) for erythropoietin stimulation for 4 weeks. Seven of them showed a transient significant average rise in the serum creatinine level of 3.8 to 6.1 mg% which partly regressed only 8 to 12 weeks after stopping the medication. The rise in serum creatinine which appears under fluoxymesterone is attributable to a transient increase in the renal excretory function disturbance and/or a raised catabolism. Warning should be given against the further use of this drug in the treatment of renal anemia.
