Cephalexin for Dogs: Uses, Dosage, and Side Effects
Published on September 18 by Ramona
Cephalexin is a broad-spectrum antibiotic commonly prescribed for dogs to treat a variety of bacterial infections. It belongs to the cephalosporin class of antibiotics and is effective against both gram-positive and some gram-negative bacteria. Here's a closer look at its uses, dosage recommendations, and potential side effects.
Uses of Cephalexin in Dogs
Cephalexin is often prescribed for:
Skin Infections: It is frequently used to treat superficial skin infections caused by bacteria, such as hot spots or abscesses.
Bone Infections: Cephalexin can be effective in managing osteomyelitis, an infection of the bone.
Urinary Tract Infections (UTIs): It is used to treat UTIs caused by susceptible bacteria.
Respiratory Infections: The antibiotic can help manage bacterial infections in the respiratory tract.
Post-Surgical Infections: It may be prescribed to prevent or treat infections following surgery.
Dosage
The dosage of cephalexin can vary based on the dog’s weight, the type of infection, and the veterinarian's recommendation. Generally, the dosage ranges from:
10 to 15 mg per pound of body weight, administered every 8 to 12 hours.
Always follow your veterinarian's instructions regarding dosage and duration of treatment. It’s crucial to complete the entire course of antibiotics, even if symptoms improve before finishing the medication.
Side Effects
While cephalexin is generally well-tolerated in dogs, some may experience side effects, including:
Gastrointestinal Upset: Common side effects include diarrhea, vomiting, or loss of appetite. If gastrointestinal issues persist, consult your veterinarian.
Allergic Reactions: Though rare, some dogs may have an allergic reaction to cephalexin, which can manifest as itching, swelling, or difficulty breathing. Seek immediate veterinary attention if you notice any signs of an allergic reaction.
Changes in Behavior: Some dogs may exhibit changes in behavior, such as increased agitation or lethargy.
Superinfection: Prolonged use of antibiotics can lead to secondary infections, such as yeast infections, due to an imbalance in normal flora.
Precautions
Medical History: Inform your veterinarian of your dog’s medical history, including any allergies or previous reactions to antibiotics.
Kidney Function: Cephalexin is processed through the kidneys, so dogs with renal impairment may require adjusted dosages.
Pregnancy and Nursing: Use caution when administering cephalexin to pregnant or nursing dogs, and consult your veterinarian.
Cephalexin can be an effective treatment for various bacterial infections in dogs when prescribed by a veterinarian. Understanding its uses, proper dosage, and potential side effects can help ensure your dog's safety and health during treatment. Always consult your veterinarian for personalized advice and follow their instructions closely.4o mini
