Hello, I am a 51 year old Caucasian female with rheumatoid arthritis and fibromyalgia. How long after stopping methotrexate (MTX), should I continue folinic acid (Leukovorin)? I was on methotrexate for ~1 1/2 years (last 6 month at 20 mg/ week). I had hair fall, then finally frank alopecia and discontinued the MTX one month ago. During the last month of treatment, I asked that my folic acid be changed to folinic acid (Leukovorin). Not sure if it helped the hair loss or not, but it helped my fingernails. I finally discontinued the MTX ~1 month ago . About 1 week after stopping MTX, I stopped my folinic acid and my hair loss seems to be worse and also my nails are splitting and my tongue is sore. ( I also had 2 Remicaid infusions 2 months ago in August and 1 week of Arava in May and am on Plaquenil (past 4 months and for awhile in the past).
