First thing to do is don't take any notice of what's written in the leaflet, its completely out of date. I would urge you to search for Vaginal Atrophy on here, you will find it very educational.
I can only speak for myself but unless you replace the oestrogen that you are losing down below, you will always suffer with VA flare ups.
I tried going down the alternative route, they didn't work with my symptoms becoming chronic which had me crawling back to the doctors asking for treatment.
I use Vagifem pessaries, Ovestin cream topically and Sylk moisturiser daily. I am now VA free, but it soon returns if I leave off the treatment.
