Escitalopram takes time to start showing its effects. Hormone replacement therapy in the form of estrogen and progesterone is also available for those who do not respond to escitalopram. You can discuss about this with your doctor. I am recommending some lifestyle changes which might help you in coping with hot flashes. Advice 1. Keep taking escitalopram regularly. Do not stop it abruptly unless suggested by your doctor 2. Regular exercise at least 30 minutes for 5 days in a week such as walking, jogging and swimming 3. Do meditation 4.
