Ive been on methotrexate, pred and hydroxy since march. In the last week ive developed a red itchy rash. Ive bought my specialist appointment forward a few weeks but i still have a week to wait. Iam taking antihistamines but it doesnt seem to help and iam so terriblly itchy. Iam contenplating taking myself off all medication to let my skin heal. Has anyone experienced this reaction before??
