Terramycin for Cats

Terramycin is an antibiotic ointment suitable for cats. Residents of most states can purchase the medication without a prescription. However, if you live in California, you will need to acquire a veterinary prescription first.

Common Eye Infections in Cats

Conjunctivitis is the most common eye infections in cats. Conjunctivitis can be a viral or bacterial in origin. Some cases occur where no cause is ever found.

Conjunctivitis occurs when the thin lining on the underside of the eyelid becomes inflamed. Getting a foreign object in the eye can also cause the inflammation. You should visit your veterinarian to ensure the cornea isn't damaged. Antibacterial eye ointment quickly clears up the condition.

Ingredients in Terramycin Eye Ointment

Oxytetracycline and Polymyxin B make up the antibacterial medications in Terramycin. They're mixed into a base of petroleum and packaged in small tubes to heal eye infections.

Oxytetracycline is part of the tetracycline group of antibiotics. The medication prevents bacteria from developing and multiplying. Polymyxin B is a sulfate. It binds to bacterial cells and causes them to absorb so much water that the cell dies off. Together, the medications team up and both kill cells and prevent them from multiplying allowing the body to quickly fight off the infection.

Proper Dosing for Terramycin

When using the antibacterial eye ointment, you should first consult your veterinarian. The medication will be administered directly to the cat's eye two to four times per day.

It's usually easiest to apply the medication by careful wrapping your cat in a towel to keep him from scratching you. Hold open the eyelid and place a small line of the medication onto the rim of the upper eyelid. Release the cat and his blinking will help spread the medication to the rest of the eye.

Side Effects of Terramycin

When using this cat eye ointment, you'll find there are few side effects. The one thing you should watch for is blurred vision. While the medication is spread to the eye, the petroleum base can make vision blurry for a while. Make sure your cat is kept in a room free of dangerous obstacles and is unable to jump up into high areas until his vision seems normal. Monitor his behavior to watch for rare incidences of allergic reaction.

Some cats are a little sensitive to the medication and their eyes may sting after administration. This is common in some cats. If you notice your cat really rubbing or scratching at his eye after using the eye ointment, call your vet for advice.

If you use the medicinal eye ointment for a prolonged period of time, the cat may develop a fungal infection or serious bacterial infection. Make sure you use the medication only as indicated by your veterinarian. If the infection hasn't improved in a few days, call your vet.

If you notice your cat's face, especially the area around the eyes, swelling or it seems like he's in severe discomfort or breathing seems difficult, immediately return to your veterinarian. While rare, this can signal a severe allergic reaction that requires emergency care.
