Summary
The topical combination has minimal systemic exposure on intact skin, so a meaningful interaction with entecavir is unlikely. Only large-area use with significant absorption could theoretically affect renal function and entecavir clearance.
What this interaction means in plain words
Bacitracin-neomycin-polymyxin and Entecavir have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Why it happens
Theoretical reduction in renal clearance of entecavir if systemic absorption of nephrotoxic components occurs.
