Been on Letrozole 3 years and still get chills not as often now. Some days I’m just tired. Eating a healthy diet and exercise helps a lot. Recently my Ferritin was at 12. I had weekly iron injections for 8 weeks that helped. Do you get bloodwork done regularly?

While chills aren't officially listed as a top side effect of letrozole, they can happen for a few reasons related to your treatment:
- Hormonal changes — Letrozole lowers estrogen levels, which can disrupt your body's ability to regulate temperature
- Fatigue — Your body uses energy to stay warm, and treatment-related tiredness can make that harder
- Loss of appetite — Not eating enough can leave your body with less fuel to generate heat
- Flu-like symptoms — Letrozole can sometimes cause chills as part of a broader set of flu-like side effects It's worth mentioning to your doctor, especially if the chills are persistent or getting worse. You should seek prompt medical advice if chills come along with:
- High fever
- Chest pain
- Unusual or extreme fatigue
- Shortness of breath
- Unexplained pain anywhere in the body
