I had a chat with Professor Lumsden about this when I saw her last week, as I covered in my previous post. GP's have a lot of catching up to do with how HRT should be prescribed! Professor Lumsden (who formulated the NICE guidelines) said that women should be prescribed HRT at the EFFECTIVE dose for their symptoms. GP's are still stuck on the WHI study and are still very nervous about prescribing at a level that addresses the individual woman's needs, preferring to stick to low doses which may be ineffective and also forcing women off HRT after 5 years of use.
Provided you are well, have no other contraindicating health problems and receive regular follow ups (and attend mammograms) there is no reason why you should not stay on it until 60, and thereafter each woman's risk of continuing treatment should be assessed on an individual basis.
As Professor Lumsden said, GP's are very slowly 'getting it' when it comes to HRT, but it's not good enough. And she is continuing to push for better awareness.
Remember, the NICE guidelines published last year are EVIDENCE BASED and you are entirely entitled to wave these under your GP's nose and demand that you receive appropriate treatment to manage your symptoms.
Hope this helps! xxxx
