I was diagnosed with IDC 3 cm in May 2007. I have had lumpectomy, chemotherapy, and radiation. I have been taking Arimidex since 12/2007--about 6 weeks. Almost from the very beginning, I have been having a rash. The first rash started about 3 days after starting the medication and was on my neck and shoulders. When this rash cleared, I developed a rash on my eyelids. After taking the drug for about 4 weeks, I developed a small rash on my arm. This has now cleared. However, yesterday I awoke with a rash on the breast around the lumpectomy area. Also, the eyelids are also itching again. I want to take this medication very badly for the obvious reasons, and this is the only side effect I have experienced so far. I read that one of the side effects of this medication is a rash. Is this normal?
Hi. Arimidex can cause rashes in 8 - 11% of those who take this drug. If the symptoms are mild, you may take anti-histamines to relieve the itching, but if the rashes are severe, you may need to shift to an equivalent drug like letrozole or exemestane.
