Neomycin not emycin (erythromycin): Yes, you can use topical creams or ointments containing neomycin and polymyxin if you are allergic to e-mycin, also called erythromycin. The three medications do not cross react. It is confusing, because 2 of the medications' names end in the letters "mycin, " but in this case the names are misleading and there is no relationship between the medications.

Yes, but....: Polymyxin cannot be used for a long time. But the combination is a legitimate substitute in most, but not all, cases.
