Diagnosed with GCA 4+ yrs ago. Had relapses at 1, 7, 5 and 4 mg pred/day. When I was on 8mg/d in July this year, Dr advised to take 15mg of Methotrexate once a week. Side effect was severe tiredeness days following taking the drug. Dr has now advised to replace Methotrexate with Imuran, an Azathioprine drug at a dose of 50Mg daily.
Does anyone have any experience of Imuran, and/or been advised to take/ not to take, and any possible side effects.
