Neo-Poly-Dex Eye Drops for Dogs and Cats

Bacterial infections of the eyes and eyelids cause swelling, redness, itching, and pain. Prescription Neo-Poly-Dex Ophthalmic for pets combines three active ingredients to treat the bacterial infection while easing discomfort for dogs and cats.

  • Contains two antibiotics to kill bacteria 
  • Includes a corticosteroid to reduce swelling and itching
  • For cats and dogs
  • Two formulations: ointment or suspension


If your pet has an eye infection, your pet's veterinarian may prescribe Neo-Poly-Dex Ophthalmic. This combination treatment contains two antibiotics, neomycin and polymixin B, to kill bacteria and help stop the infection. Neo-Poly-Dex also contains dexamethasone, a corticosteroid that effectively reduces inflammation and itching associated with the infection.  Neo-Poly-Dex is available as an ointment or suspension. 


What you should know about Neo-Poly-Dex Ophthalmic:

  • Talk to your pet's veterinarian before using this product. 
  • Follow dosing directions exactly - don’t give your cat more medication than directed and don’t skip doses. 
  • Read the label carefully for information about storage, possible side effects, and drug interactions.

Resistance is a major concern when giving antibiotics. Resistance occurs when bacteria survive and mutate and are then able to survive even after antibiotics are given. To help avoid any resistance, it is important to give antibiotics as they are prescribed for as long as they are prescribed even if your pet is looking and feeling better.
