You can ask your pharmacist about
any steroid foams or enemas. Generally they are either hydrocortisone or buedisone-based.
The steroid enemas go much further than most foams do (with the exception of uceris-foam that goes up the left side at least to the sigmoid colon). Entocort is an example of a steroid enema and that would treat the whole left side.
