Terramycin is an antibiotic ointment used to treat and prevent eye infections in dogs.
How to use
Terramycin is available without a prescription in all states except California. Still, it is essential to take your dog to a veterinarian to receive a proper diagnosis and a recommendation to use this product before applying it. It should be applied two to four times per day. It is best to use a helper when applying an ointment to a dog's eye. The helper will restrain the dog and hold its head steady while the other person gently pulls the lower eyelid out and squeezes a tiny drop of the ointment inside the eyelid. As the dog blinks, the ointment will spread over the surface of the eye.
How it works
Terramycin is used to treat a wide range of conditions of the eye, including pink eye, corneal ulcers and lesions, conjunctivitis, an inflamed cornea, inflammation of the eyelids, and minor bacterial infections of the eye.
The ointment contains two different antibiotics, oxytetracycline hydrochloride and polymyxin B sulfate. Together, they can eliminate most Gram-positive and Gram-negative bacteria. Oxytetracycline blocks bacteria from synthesizing proteins, causing them to die rapidly. Polymyxin B is only effective against Gram-negative bacteria, and it kills them by breaking down their cell membranes. It can also bind to endotoxins and inactivate them. Polymyxin B is extremely effective against the bacterial species Pseudomonas aeruginosa, the most common cause of infections of the eye.
It is important to wash your hands before handling the tube of ointment. It is also important to avoid touching the tip of the tube to anything; the product is sterile, and if the tip touches the dog, a person's hand, or some other surface, it could become contaminated with pathogens that could worsen the dog's condition.
If the dog's condition worsens or doesn't improve after a few days of application of this ointment, it is essential to contact your veterinarian immediately.
Prolonged, long-term use of this product should be avoided. Prolonged use can induce the development of fungal or antibiotic-resistant bacterial infections of the eye.
No other products should be applied to the eyes while using this ointment since they may interact with the antibiotics.
Side effects in dogs are extremely rare. There may be some mild stinging of the eye after the application of each dose.
