What are some possible side effects of exemestane (aromasin)?

Menopausal-like: The most common side effects include hot flashes, fatigue, joint pain, increased sweating, headaches, and sleep problems. However, most women tolerate Aromasin (exemestane) very well and less than half of the women who take this drug have any side effects at all.

Joint pain and more: 30-40% of women have severe joint pain, and studies show that many stop taking the drug without telling their doctors! vaginal dryness, hot flashes, and fatigue are common troubling symptoms. Some women have fewer side effects with other aromatase inhibitors, so tell your doctor if you have symptoms bad enough that you consider stopping your medication.
