What can help with vaginal irritation while taking Anastrozole?

I have been on Anastrazole for 1 year for my ER/PR breast cancer and have been having issues with vaginal irritation / itching. I do use Halogyn suppository gel three times a week per my gynecologist for moisture but it doesn't seem to help much. It's been pretty bad for a couple of weeks so I've tried monistat and some cream that you get at the pharmacy with no benefit and now my gynecologist has left the practice and I can't get in to see another one till August. Has anyone had this type of situation and has there been anything that you've used to help? Thank you
