How it works

A clinician injects local anesthetic into the stellate ganglion, a nerve bundle in the neck that is part of the sympathetic nervous system. This may interrupt the temperature-regulation signals that trigger hot flashes.

SERMs bind to estrogen receptors and act like estrogen in some tissues (bone, vagina) while blocking estrogen in others (breast, uterus). This tissue-selective action can treat menopause symptoms without systemic estrogen.
