Side Effects of Cephalexin for Pets
Veterinarians prescribe cephalexin to treat bacterial infections in cats and dogs, namely skin, wound, bone and bladder infections, and pneumonia. The drug works by inhibiting the bacteria from developing a durable cell wall, thus bringing about the death of the bacteria. Cephalexin does not protect against parasites, mites, viruses or fungi. Like any prescription drug, cephalexin has the potential to trigger a variety of side effects.
-
Vomiting
-
Vomiting is the most common side effect in both cats and dogs. It is not a symptom of a larger disease, nor is it often cause for concern; vomiting simply signifies that the animal is sensitive to cephalexin. In the event of excessive vomiting, or vomiting that seems bothersome or painful to the animal, a veterinarian should be consulted.
Diarrhea
-
Like many orally administered antibiotics, it is not unheard of for pets to develop a mild case of diarrhea and/or nausea upon taking the drug, though this for the most part is a rare occurrence. If these symptoms persist for an extended period of time, notify a veterinarian.
-
Allergic Reactions
-
Allergic reactions to cephalexin are not unheard of ---- namely itching, hives, rash, swelling of the lips, tongue or face, and difficulty breathing. Seek veterinary attention if the pet exhibits an allergic reaction.
Side Effects Specific to Dogs
-
Cephalexin may induce excessive drooling in dogs, as well as rapid breathing and excitability.
Side Effects Specific to Cats
-
Cats may be prone to developing a fever, and if so, should be taken to a veterinarian for further examination.
Precautions
-
Cephalexin should not be administered to pets with hypersensitivity or a known allergy to the drug. The standard dose is 10 to 15 milligrams per pound, given orally every eight to 12 hours for both cats and dogs. In order to prevent the animal from developing resistance to the drug, the treatment plan implemented by the veterinarian should be followed through with until completion, even if the pet begins feeling noticeably better. Side effects can be reported to the Food and Drug Administration at 800-FDA-1088.
