Yes you are right @quirkychick
It is a BP med.
However, the same principle applies that HRT is the first line of treatment.
If you want to google- loads online- you will see that the only real no-nos for HRT are recent cancer, recent blood clot, recent heart attack. Nothing else matters (except a very strong history in immediate family of b cancer.)
Also, the medical info says that transdermal estrogen does not raise the risk of blood clots beyond the individual's baseline risk.
NICE
1.5 Long-term benefits and risks of hormone replacement therapy
Venous thromboembolism
1.5.1 Explain to women that:
the risk of venous thromboembolism (VTE) is increased by oral HRT compared with baseline population risk
the risk of VTE associated with HRT is greater for oral than transdermal preparations
the risk associated with transdermal HRT given at standard therapeutic doses is no greater than baseline population risk.
1.5.2 Consider transdermal rather than oral HRT for menopausal women who are at increased risk of VTE, including those with a BMI over 30 kg/m2.
1.5.3 Consider referring menopausal women at high risk of VTE (for example, those with a strong family history of VTE or a hereditary thrombophilia) to a haematologist for assessment before considering HRT.
You might also be better off on natural micronised progesterone rather than a synthetic type as in the Mirena.
