I was just prescribed Methotrexate for RA today and I have heard so many negatives about it. One major side affect is HAIR LOSS.. I have very long hair and it has already been falling out due to the illness itself, I can't afford for it to get any thinner. Just wondering if anyone has been on this drug for a long time, how much of your hair falls out? A lot or a little? I'm really scared to start this new med. And how long did you have to take it to be able to tell a difference in the way you feel? Please help!
