Exemestane (Aromasin) is an aromatase inhibitor (AI) commonly prescribed for hormone receptor-positive breast cancer. It works by blocking estrogen production in the body, which helps slow or stop the growth of cancer cells that are fueled by estrogen.
It's typically prescribed after initial treatments like surgery, chemotherapy, or radiation to help keep cancer in remission. It's most effective for postmenopausal women, and can be taken for five to ten years after surgery. Like other aromatase inhibitors, exemestane can come with some side effects. Here are the most common ones to be aware of:
- Joint, bone, and muscle pain — this is one of the most frequently reported side effects
- Hot flashes — a result of lower estrogen levels
- Fatigue — feeling more tired than usual
- Osteoporosis — reduced bone density over time
- High cholesterol — worth monitoring regularly
- Sleep disturbances — including difficulty falling or staying asleep
If side effects become hard to manage, it's really important to talk to your oncology team before stopping the medication. There may be alternative solutions or adjustments they can suggest. Many MyBCTeam members have shared their experiences with exemestane — some find the side effects manageable, while others find them more challenging. You're definitely not alone in navigating this! Connecting with others on the team who are on the same medication can be really helpful for tips and support.
