Why not gel then ? As you can play around with it , there is somewhere on the wide world net reasons why you should NOT cut patches.
The reason given is a scientific one that I can't remember. HRT is really important for pelvic health , I don't feel the average GP practice nurse knows much if anything about HRT, it's why I have had to go private , shouldn't but I have the bladder/ vagina from hell. Although better than it was. Aka 5 times a week vagifem and sandrena gel.
The specialist I no of via a friend said , GPs are still very ignorant/ arrogant about HRT and are ignoring the latest guidelines , where it clearly states local OESTRGEN can be used for life as can full HRT , with the risks benefit ratio known, also if more local HRT is needed than two /three times a week then that's Fine.
If you do the ,ATMs as to how much each vagifem contains of OESTRGEN it is minute tiny tiny , it can't over OESTRGENise you.
