Femara
"I've been taking letrozole(Femara) 9 months, after a right side mastectomy for stage IIA breast cancer.  I'm ER & PR positive.  No radiation or chemo.  I'm 58 & this is the only drug I take, besides vitamins.  The first 6 weeks I had trouble sleeping, occasional dizziness, some joint pain, & mild headaches.  Around 4 months in, I started losing hair.  I'd guess approximately 25% of my hair has fallen out.  Besides the hair loss, I have dry eyes, genitals, & skin.  There's some stiffness & joint pain in my hips.  These side effects are tolerable, especially, knowing that the drug is preventing a cancer recurrence.  None of these side effects are enough for me to stop taking letrozole!"
