It is a know side effect - hot flashes and night sweats. It is because of lower estrogen levels. Just like menopause.

This discussion talks about same symptoms, but with a different drug used during breast cancer treatment, tamoxifen. https://connect.mayoclinic.org/discussion/alternative-medicine/

Sounds like it is affecting your quality of life and you should let your providers know.
Have you talked to your oncologist or care team about?

@roch yes. They suggest stopping Letrozole for three weeks to see if it gets better and then talking with the oncologist to perhaps change drugs. Of course last night I didn’t have any! I had stopped Letrozole for two weeks for surgery that I had to have and went back on it 9/17 so perhaps it is resolving? I am not supposed to stop it until 10/17 and if I no longer have then I will stick on the drug since I believe Letrozole is the drug of choice for jar positive invasive lobular cancer.

I did a search but couldn’t find anything. One person said take primose oil but my research shows that it shouldn’t be taken with letrozole.
