Drug & Food Interactions

Do not administer other steroid hormones during treatment with this medication. Do not use in combination with other aminoglycosides, such as neomycin. Notify your veterinarian of any other medications, including vitamins and supplements, your pet is taking while your pet is receiving gentamicin.


Before putting any medication into your pet's ear ear, examine the external ear canal thoroughly to be certain the tympanic membrane is not ruptured—this can cause the infection to spread to the inner ear, or damage the cochlea. If hearing or dizziness or lack of coordination due to inner ear damage is noted during treatment, discontinue use. Do not use in animals with known allergies to any of the ingredients. Prevent ingestion of the medication.

    Pharmacy Issues

    By CaptainObvious on Jun 17, 2020

    This is the second time I have had issues with Chewy pharmacy... I get the point that they need approval from the vet for prescriptions but it took us almost two weeks and a countless number of phone calls to get some coordination between the two. They tell ya that you and your pet are very important to them but I really don't think the pharmacy gives a d a m n. The other services have been great for providing food, treats, etc, but the pharmacy is terrible. Will be looking elsewhere my pharmaceutical needs for my pet.

    Wow, even the pharmacy is amazing. They contacted the vet for the prescription and the bottles arrived in light speeding time even in those strange times we are in. Cheaper then anybody else. Thank you and stay safe Ursu
