My mother has been on Revlimid and Dex.for a month, She developed a horrible rash on her face. (like acne) The doctor took her off dex and revlimid until it cleared up. She is going to be taking revlimid next week. Has anyone else had this reaction? While taking dex by itself she did have a mild case of acne. She is 78 years old. She has been taking dex for 16 months and a bone builder. Now the doctor has added revlimid to her regiment.
