Enhance activities of ciclosporine, antidiabetics, thyroxine, anticoagulants. Long term use of testosterone may cause resistance to effects of neuromuscular blockers. Enhance fluid retention from corticosteroids.
May decrease protein bound iodine (PBI) and thyroxine-binding globulin concentrations. May cause a decrease in excretion of creatinine and creatine and increase in excretion of 17-ketosteroids.
Category X: Studies in animals or human beings have demonstrated foetal abnormalities or there is evidence of foetal risk based on human experience or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit.
