Does anyone else in this WHOLE WORLD have Asthma, multiple allergies & PD ? Even before my PD had a name I knew something was terribly wrong as everytime I took an antihistimine I fell flat on my face within an hour. My Pulmonary Doctor & I have tried EVERYTHING. The only thing I can tolerate is Cortisone, and then I have to take it over a 7 to 10 day period. I would like to find an antihistmine I could tolerate, I need it soon or will have to start on Cortisone. P.S. I'm allergic to aspirin so any over the counter medications usually won't work. As Ever, Marjorie Moorefield just another librarian (with PD) in Florida
