Marbofloxacin is a custom pharmacy drug classified in the family of drugs known as fluoroquinolone antibiotics. Marbofloxacin is used in veterinary medicine to primarily treat cat and dog infections. Fluoroquinolone antibiotics work by deactivating DNA gyrase, which promotes the death of bacterial cells.


Marbofloxacin will be given in an appropriate form for your pet's needs. Consult with your veterinarian for specific information on dosage. Administer this drug to your pet for as long as you are instructed and complete the entire course regardless of whether your pet seems to be feeling better or not. Stopping short on the entire medication course could possibly allow the infection to rebound. Never give your pet more than is directed by your veterinarian.
