Hello Ralph: A common skin disorder associated with PD is SEBORRHEA: the oil glands secrete a substnace that inflames the skin and causes redness and greasy scaling. The rash shows up as yellow-red patches of scales...usually on the scalp, the face and chest. Its direct cause is unknown.... Selsun Blue shampoo works in mild cases....and hydrocortisone cream .05% is effective. Good luck Stephan 55/9 >>> Ralph Reichert <[log in to unmask]> 02/03/00 05:08pm >>> Dear colleagues of the List: Has anyone heard of a rash developing after years of taking carbidopa/levodopa, ( 25/100) that was attributed to either component of this drug? Please reply if you have any information> Thanks, Ralph.
