A rash is common with Revlimid, but I'm not sure why you are getting a rash after being on it awhile. You will need to let your doctor know. They usually give steriods, antihistamines, and maybe steriod skin cream💕
Call your doctor asap. I also had a rash. They gave me prednisone. Then we tried 5mg. Same result. I had to discontinue revlimed. My rash was intense and borderline dangerous.
