I was wondering how many mg you are on of the Methotrexate? How often do you take it? I am on 7.5 mg a week. I have not experienced any side effects other than some hair breakage near the face. I have been taking it now for 2 months. My doctor is wanting to increase the mg's so I am wondering if I will have more side effects? Is hair loss a common side effect with Methotrexate?
