The information in VA medication leaflets is OUT of date, Dr Newson is trying to get Companies to class it as medication rather than HRT. VA treatment is safe to use every night when necessary and when symptoms flair for me, I put an extra dose of 'estriol' up in the afternoon and then every night for 5.
Some find that 'sylc' or 'yes' products on the outer labia eases soreness or inserting 'vagifem' and using 'estriol/ovestin' externally.
Let us know how you get on.
