Gentaved and Prednisolone combo for skin problem?

Rather than try another shot of Depo Medrol for my 9 year old female
longhair (last one was three months ago), our vet replaced Tresaderm with
Gentaved and added 5 mg/day of Prednisolone to try and stop the licking
which is either the cause or the effect of her hind leg sores.

Anyone have experience with Gentaved? I know it's a combo of an anti-
biotic and a corticosteroid.

Since I don't give her the Prednisolone by mouth, that means I have to
crunch into powder and get the low sodium turkey breast, or some Boars Head
roast beef. She actually will eat the pill powder as long as I roll some
small pieces of the meat around it.
