I am on NSAID, Prednisone, Methotrexate and now Enbrel. Since I started Enbrel I have been getting sick to my stomach when I take my Methotrexate. I take 8 pills a week. I was going to ask my doctor about injectable Methotrexate. Is hard to inject? I find that the Enbrel easy to inject with now site reaction. Would it help with being sick to my stomach? Is there any mixing of the drug? Any information would be great. Thanks.
