Health & WellnessDog eye ulcer not healing with Vetropolycin? Switched to Terramycin.
Hello. When an infection or lesion has been treated for a time & it has not totally cleared up, it is always a good idea to switch to another medication. Vetropolycin is a triple antibiotic containing Bacitracin, Polymyxin & Neomycin & is generally prescribed for conjunctivitis. Terramycin contains oxytetracycline which is a bit more broad spectrum & is indicated in treating not only conjunctivitis, but other ocular conditions including corneal ulcers. Some ulcers do indeed heal very quickly, but sometimes we do run into a stubborn one. As long as the ulcer seems to be resolving, continue the medication & do make sure you have your veterinarian recheck the eye in about a week. Thanks for using Petco Pet Education Center, formerly Petcoach.
