@daisy17 I am 63 I asked the same thing but I found on the web this : Key Age Considerations for HRT
Under Age 60: Starting HRT before age 60 or within 10 years of menopause onset is generally considered to have a more favorable benefit-risk profile, particularly for heart and bone health.
Over Age 60/65: While once a common "cutoff," modern research shows that healthy women with persistent symptoms can safely continue HRT beyond age 65 with regular medical evaluation.
Long-Term Use: You can potentially take HRT for the rest of your life. However, doctors often recommend yearly reviews to assess if the benefits (e.g., symptom relief, bone protection) still outweigh increasing age-related risks like breast cancer or blood clots.
