Product Description

Cephalexin oral suspension is a widely used oral antibiotic in veterinary medicine. Specifically formulated for pets, it is a potent treatment for various bacterial skin infections, particularly pyoderma. While its primary indication is for dogs, it is also used off-label or extra-label in other animals such as cats, horses, ferrets, reptiles, and birds, particularly for pyoderma and other skin infections. It's also used off-label in treating some urinary tract infections in cats and dogs.

  • Administration and Dosage:Cephalexin is available as a liquid oral suspension and is convenient for pet owners to administer. Depending on the veterinarian's recommendation, it can be given with or without food. In cases where the pet vomits or appears unwell after medication, administering it with a small amount of food can mitigate gastrointestinal discomfort. It's necessary to shake the suspension well before use and measure doses carefully to ensure accurate dosing.

  • Onset of Action and Duration:Cephalexin typically starts working within one to two hours after administration, although visible effects may take a few days to become apparent. It is crucial to complete the full course of antibiotics as directed by the veterinarian, even if the symptoms improve before the medication is finished. If a dose is missed, it should be administered as soon as remembered. However, if it is close to the time for the next scheduled dose, it's best to skip the missed dose and continue with the regular dosing schedule. It's imperative never to double up on doses or administer extra doses.

  • Side Effects and Precautions:Side effects of cephalexin in pets are usually mild and rare. Gastrointestinal upset, including lack of appetite, vomiting, and diarrhea, may occur but typically resolve on their own. However, if side effects become severe or persist, it's essential to contact the veterinarian promptly. Signs of a potential allergic reaction to the drug include fever, rashes, difficulty breathing, and pale gums. In such cases, immediate veterinary attention is warranted. Cephalexin should not be used in pets with a known hypersensitivity or allergy to cephalosporins. Caution is advised when administering to pets sensitive to other antibiotics, including penicillins, rapamycin, and carbapenems. Additionally, it should be used cautiously in pets with kidney dysfunction, as well as in pregnant and nursing mothers.

  • Storage and Disposal:To maintain efficacy, Cephalexin oral suspension should be stored in the refrigerator. It is crucial to adhere to the expiration date and dispose of any unused medication after 14 days of opening the sealed container. Proper storage and disposal help ensure the safety and effectiveness of the medication for your pet's treatment.

Cephalexin oral suspension has proved valuable in treating bacterial skin infections in pets. However, following your veterinarian's directions and cautions carefully is essential to ensure the best outcome for your furry friend.
