anastrozole

Hi Moly,  my situation was a little different as I had been on anastrazole for about 6 months.  I started to get itchy basically on my chest and near my underarms.  I have atopic dermatitis so thought it was that at first but had never had any issues of itching from that in that area.  The itching became worse so saw oncologist and told her I thought it was anastrazole.  Well she gave me meds for itching and told me to stay on the Anastrazole and call her in a few days.  Well the itching got worse and started to spread to other areas so on Sunday I stopped taking it.  Called oncologist Monday and she told me to stop anastrazole for 2,weeks and continue with antihistamines.   I didn’t get any better off the Anastrazole and felt tired from the antihistamines so decided it must be something else.  Only thing I could come up with was a benzoyl peroxide wash that I had been using under my arms as I didn’t need antiperspirant if I used it.  Well guess what it was that wash that I had become allergic to.  I had been using it for well over a year. 
If you have started to use any new products on your skin you may look into it.  Sometimes it can be the Anastrazole but maybe not.  Good luck in getting to the root cause.  If it is Anastrazole they can try letrozole or exemestane.  Take care.
