You can buy Eumovate CREAM over the counter and this is/can be different to that you are prescribed. The scrip I got for it was an ointment and stronger. Though available over the counter I have been told that it is a 'medium' strength steroid and not 'mild' as you would expect.
Though the lit in the pack tells you that it is not to be used for P OR on the face, some derms say it is OK for short periods of time, some will not prescribe it for the face at all (it being a medium steroid etc).
The problem with using steroids on the face is the old 'vicious circle'; you use it and it helps the P but as soon as you stop using it the P comes back and then you start to use it again until it doesn't make any difference to the P very much and then you are risking the side effects and, as the derms put it' 'abuse of a steroid'.
I used Eumovate with moderate success a few years back, but I was very worried about abusing it. So I stopped and let Doublebase and time take effect.
Be careful. I personally think your doc is wrong to allow you to use it for so long unchecked.
