when nhl play resumed in 2005–06, it was revealed on february 9, 2006, he had failed a random drug test conducted prior to the 2006 winter olympics. the failed test was later revealed to be caused by a prescription hair loss medication propecia, which théodore had been taking legally for eight years. propecia contains the drug finasteride, which can be used as a masking agent for the performance-enhancing drug nandrolone among weight-trainers and bodybuilders, but it is not a performance-enhancing drug in itself. théodore did not face any punishment from the nhl because he had applied and received approval for a therapeutic use exception. however, he did receive a two-year suspension from international play.
