Polytrim Eye Drops for Dogs

Polytrim is an ophthalmic medication that is used to treat bacterial infections of the eye in dogs and cats. It is a combination of two antibiotics, polymyxin B and trimethoprim, which work together to kill bacteria that are causing the infection. Specifically, polymyxin B sulfate is an antibiotic that works by killing sensitive bacteria in the eye, while trimethoprim prevents the growth of bacteria by stopping the production of essential proteins.

Polytrim is frequently recommended by veterinarians to address issues like conjunctivitis (commonly known as pink eye) and other bacterial eye infections in dogs.

Just like with human medications, it's crucial to follow the veterinarian's instructions meticulously, finish the entire treatment as advised, and administer the medication exactly as prescribed. This helps achieve the best results and reduces the risk of antibiotic resistance or adverse effects. Always seek advice from a veterinary professional for accurate diagnosis and treatment suggestions for your dog.

Polytrim is highly effective in treating a wide range of bacterial eye infections and related conditions in dogs. Its efficacy and versatility make it a valuable tool for veterinarians in managing various eye disorders.

Common bacterial eye infections treated with Polytrim

• Conjunctivitis: conjunctivitis, also known as pink eye, is a common bacterial infection that affects the conjunctiva, the lining of the eyelids and eyeball. Puppies and adult dogs are equally susceptible to this infection. Polytrim can effectively treat conjunctivitis, alleviating symptoms such as redness, swelling, discharge, and discomfort.
  
  
• Secondary eye infections: in cases where dogs develop secondary bacterial infections due to underlying eye conditions or injuries, Polytrim can be effectively employed to prevent or control these infections while addressing the primary issue.
  
  
• Post-traumatic eye injuries: following trauma or injuries to the eye, such as scratches or foreign objects entering the eye, veterinarians may prescribe Polytrim to prevent secondary bacterial infections and promote healing.
  
  
• Surgical aftercare: Polytrim plays a crucial role in ophthalmic surgery, both before and after procedures. It is used as a prophylactic measure to prevent bacterial infections and ensure proper healing during the post-operative period.
  
  
• Recurrent eye infections: for dogs prone to recurrent bacterial eye infections, particularly those associated with chronic conditions, Polytrim may be incorporated into a treatment plan to manage and prevent the recurrence of these infections.

Specific bacterial eye infections addressed by Polytrim

• Purulent bacterial conjunctivitis: this type of conjunctivitis is characterized by inflammation of the ocular conjunctiva, leading to symptoms such as red eyes, pus (thick yellow discharge), burning, and itching. Polytrim effectively combats this infection, alleviating these uncomfortable symptoms.
  
  
• Keratitis: keratitis refers to inflammation of the cornea, the clear outer layer of the eye. In dogs, bacterial keratitis can cause eye pain, redness, blurred vision, and sensitivity to light. Polytrim effectively treats bacterial keratitis, alleviating these symptoms and promoting corneal healing.
  
  
• Corneal ulcers: these are open erosions in the cornea that typically manifest with symptoms such as eye discharge, pain, blurred vision, and red eyes. Polytrim effectively treats corneal ulcers, promoting healing and reducing the risk of complications.
  
  
• Chronic Dacryocystitis: this condition involves prolonged inflammation of the lacrimal sac, the structure responsible for tear production. Symptoms in dogs include excessive tearing, recurrent infections, eye pain, and red eyes. Polytrim effectively treats chronic dacryocystitis, alleviating these symptoms and restoring normal tear drainage.

The dosage of Polytrim for dogs varies depending on the weight of the dog and the severity of the infection.

• For dogs weighing under 4.5 kilograms (10 pounds), the typical dosage is 1-2 drops in the affected eye(s) 1-2 times per day for 7-10 days.
  
  
• For dogs weighing 4.5 kilograms (10 pounds) or more, the typical dosage is 2-3 drops in the affected eye(s) 1-2 times per day for 7-10 days.

It is important to follow the veterinarian's instructions carefully when administering Polytrim to your dog. Do not use more Polytrim than directed by your veterinarian. If you miss a dose, give the missed dose as soon as you remember, but do not give two doses at once.

If your dog's eye condition worsens or does not improve after 7-10 days of treatment, take your dog to the veterinarian.

As with any medication, it is important to be aware of the potential contraindications of Polytrim before using it on your dog.

• Hypersensitivity to trimethoprim or sulfamethoxazole: Dogs who are allergic to either of these antibiotics should not be given Polytrim.
  
  
• Perforating eye injuries: Polytrim should not be used in dogs with perforating eye injuries, as it can increase the risk of infection and worsen the injury.
  
  
• Pregnancy and nursing: Polytrim should not be used in pregnant or nursing dogs, as it can be absorbed systemically and potentially harm the developing puppies or kittens.
  
  
• Kidney or liver disease: Polytrim should be used with caution in dogs with kidney or liver disease, as these conditions can affect the body's ability to metabolize the antibiotic, potentially leading to toxic buildup.
