sorry, don't know anything about that..not a mental health problem...
I am not sure. Did your doctor indicate that they might? You might like to research the name of the pills for more information. I sometimes use the website rxlist.com.
You may find some more information on the breast cancer forums. People there will probably be a little more informed about such things.
I would have expected a doctor to discuss all this prior to you being prescribed the med.
Good luck -I think!
