Hello Mrs Bennet,
Go ahead and use the Vagifem. Don't be put off by the leaflet as most of the information in it is the same as for full HRT, so is not relevant for local oestrogen. I know it's daft, but that's how they do it! You will need Vagifem for the rest of your life, as symptoms return if treatment is stopped, so it would be as well to get started so that you feel better sooner rather than later.
CLKD is right about quality of life, and I should say that Vagifem is as near as one can get to risk-free; many of us have to use it every night as the dose of estradiol is so tiny. However, you may get on fine with the initial loading dose of two weeks nightly, then twice a week. If you find that doesn't do the trick, use it more frequently.
Best wishes,
