Long-lasting otic solution containing mometasone furoate can influence intradermal testing in dogs with healthy ears and otitis externa.

Application of a long-lasting otic solution containing MF can interfere with IDT immediate reactions in healthy and OE dogs. Based on the subjective evaluation, IDT can be performed ≥2 weeks after application of the otic solution in healthy dogs, and ≥4 weeks in dogs with OE.
