Terramycin Ophthalmic Ointment is a prescription veterinary antibiotic formulated as a bright yellow ointment suspending oxytetracycline hydrochloride and polymyxin B sulfate in a petrolatum base. It requires a valid prescription from a licensed veterinarian and is labeled for topical ophthalmic use only. The label directs that the ointment be applied directly to the affected eye two to four times daily, with care taken to avoid touching the tube tip to the eye or any other surface. Each tube is supplied for topical administration and is intended for animal use only, not for humans. The product is packaged as individual tubes and should be stored at controlled room temperature, with brief excursions to cooler or warmer conditions permitted. Veterinarians determine the appropriate course of treatment and duration based on the specific infection being addressed.
