Hi XXXXXXX If it is just a yeast infection without any bacteria then using a different ear medication may be safer. Conofite or other miconazole drops can be used. Also Lotrimin or other clotrimazole drops can be used. Tresaderm or the new Baytril drops can also be used for mild yeast infection. The other big thing is to clean the wax out of the ears daily. Yeast need the wax to survive. Yes you can use Otomax, but as Dr Williams pointed out the antibiotic in it (gentocin) as some risk to it. Hope that helps, Jerry Murray, DVM [Posted in FML issue 3397]
