can you mix these meds together

I really don't know, but I thought the silver sulfadiazine cream was a topical medication. Since it was put on a mouth abscess, maybe some of it was swallowed and that caused a problem?

While ingesting silvadene is potentially toxic, the OP did not say whether the abscess was in, on or around the mouth.

A snake isn't like a dog - it isn't going to use it's tongue to lick or ingest enough of the ointment to be toxic.

I doubt that a Vet would prescribe silvadene in an area where it could be ingested - but maybe I'm wrong................
