Use the pessaries every day until you start to feel better then reduce the dose if you can, if pessaries alone are not helping you can also use an oestrogen cream to smear on the outside. Treatment can take four months to take effect, patience is the key here.
The tablet composition should not have changed, if they have given you a cheaper version ask for what you had previously, some women don't get on when changed to a different pessary, something to do with the filling they use.
