Regarding the moisturisers, some surgeries will prescribe, but the products (eg, Replens) are not always suitable for all. Also, because these products are available otc, I think they might be reluctant. If they will prescribe Sylk and you get free prescriptions, it might be worth getting some. It is useful for dipping the Vagifem applicator into the bottle to aid insertion, and it will help the Vagifem adhere to the vaginal wall if you are dry inside 😊.
