Have you been reading the Daily Mail ?
Continuing to take medication, any medication, longer than necessary is undoubtedly not going to recommended by many GP's. (And not always for the right reasons.)
Menopause is a naturally occurring stage of life, and although using medication to help with the horrible symptoms is obviously going to be of great help, particularly if someone reaches this 'stage' earlier than is considered 'normal', it's not something that many GP's would be happy to continue to prescribe for the rest of your life because the risks eventually begin to outweigh the benefits.
But I'm happy to concede that this may vary between GP's, but I'd think that most would advise against lifelong use because of the cost, and the increased risk to benefit ratio with age, and the regular monitoring extended use would require (especially as no-one can even get a face to face appointment for illness at the moment, never mind regular BP's and bloods for regular monitoring). Also, as you get older, you often need other medication for other conditions, which may be either contraindicated or prescribe with caution (because of the increased risks), even for common conditions such as migraine or diabetes etc, which would make many GP's think twice about continuing to prescribe HRT.
So I'm afraid it's not as simple as ''you can take it for life'.
