I am new to RA. In the past I have used Echinacea when I felt like I had a cold coming on. I read on the information pamphlet that I recieved with my RX for Methotrexate that I should not use it. Now I have a cold and wonder what OTC remadies I could maybe use. I used to use elkaseltzer plus also and wonder if I could use that. I'm pretty frustated as I haven't had a cold in a very long time. I am also on prednisone, hopefully for the short term only.
