How long before HRT patch starts working?
Patches are neither the most effective or efficient form of HRT as their absorption is very variable.I always described them as women’s magazine medication more hype than substance. I very much hope that you are either being prescribed an oral sequential progestogen unless you have had a hysterectomy, as unopposed oestrogen CANNOT be used otherwise due to the risk of doubling ovarian cancer risk and also endometrial cancer. Assuming one or other of these is the case and your patch is ‘safe’, (ignoring the inherent risks of all HRT,) then your 25 patch is the lowest dose and is seldom sufficient to abolish symptoms.
