How quickly does hormone replacement therapy relieve hot flushes?

Hormone replacement therapy replaces hormones that have fallen around menopause. As levels settle, episodes of heat, sweating, flushing, and night waking may become less frequent or less intense. The response depends on the preparation, dose, route, and your symptoms. Early side effects can overlap with menopause symptoms, so a short period of adjustment does not necessarily mean the treatment will not help.

Record flushes, night sweats, sleep disruption, and any new effects after starting treatment. Use the prescribed product exactly as directed and do not change the dose without advice. Arrange a treatment review if symptoms remain difficult after the initial adjustment period. Your clinician may discuss the dose, delivery method, other causes of sweating, or non-hormonal options.

Seek urgent help for chest pain, sudden breathlessness, coughing blood, or one-sided leg swelling and pain. Contact your clinician promptly for unexpected vaginal bleeding, a new breast change, severe headache, or symptoms that are rapidly worsening. Do not wait for a routine review if you feel seriously unwell.

Ask when your treatment should be reviewed, what bleeding is expected, and whether your medical history changes the safest option. Ask what to do if flushes continue or side effects interfere with daily life.
