Warnings & Precautions

Serious, life-threatening hypersensitivity (anaphylactic) reactions have been reported in some cats following application of antibiotic ophthalmic preparations. If your cat's face swells, it seems itchy, appears weak, vomits, or has difficulty breathing within 4 hours of application, you should stop treatment and contact your veterinarian immediately. Using oxytetracycline and other antibiotics may lead to an overgrowth of resistant organisms such as Monilia, staphylococci, and other bacterial species. If new infections due to nonsensitive bacteria or fungi appear during therapy, appropriate measures should be taken.
