"Exemestane is the 3rd anti estrogen medication I have taken. I was not able to take Tamoxifen due to a bad interaction with another medicationI take. The first 2other aromatase inhibitors I took gave me severe side effects. Exemestane has been the best so far, but it does give me insomnia and then fatigue, and headaches. My main problem is the expense! Although it is generic it is much more costly than the other medications I was on and I can't understand why!"
