Hi there,
My husband was diagnosed on April 13th with glioblastoma IV, and withing a week, he went on Lexapro (doctor chose that one because it is fast acting). It has worked beautifully, and has not had a bad interaction with any other meds...temador, decadron, keppra, etc., etc.
As a matter fact, I'm on it as well. It has worked fast to lift our spirits and get us through this terrible time.
Good luck. My thoughts and prayers are with you.
Alison
