For 14 years husband has been taking nutritionals rated #1 in the world. Aprox 2 yrs ago he was diagnoised with Myasthenia Gravis - He has been taking Prednisone and Pyridostigmine BR 60mg at perscribed directions. The past 6 months he has been loosing his hair by the "handsfull". Is there any known side effect or connection of "natural nutritionals and either of these Rx's" that would cause the hair loss.
