Frequently Asked Questions
How much Cephalexin should I give my cat?
The standard veterinary dose is 10–15 mg per pound (22–33 mg per kg), given every 8–12 hours. For example, a 10 lb cat typically receives 100–150 mg per dose, three times daily. Always follow your vet's specific prescription, as doses vary by condition.
What is Cephalexin used for in cats?
Cephalexin is a first-generation cephalosporin antibiotic used to treat bacterial skin infections (pyoderma), urinary tract infections (UTIs), soft tissue infections, and wound infections in cats. It is effective against gram-positive bacteria including Staphylococcus.
Can I give my cat human Cephalexin?
While the active ingredient is the same, human formulations may contain different fillers or concentrations. Use veterinary-prescribed Cephalexin when possible. If using human Cephalexin, ensure it contains only cephalexin and no other active ingredients.
What are the side effects of Cephalexin in cats?
Common side effects include diarrhea, vomiting, and loss of appetite. Less common: allergic reactions (hives, facial swelling), difficulty breathing, or skin rash. Contact your vet if your cat shows signs of an allergic reaction or severe GI upset.
How long does Cephalexin take to work in cats?
Most cats show improvement within 48–72 hours of starting Cephalexin. However, complete the full prescribed course (typically 5–14 days) even if symptoms improve early to prevent antibiotic resistance and ensure the infection is fully resolved.
Can Cephalexin be given with food?
Yes, and it is recommended. Giving Cephalexin with food reduces gastrointestinal side effects like vomiting and diarrhea. If your cat refuses food, try mixing the medication with a small amount of wet food or a treat.
Is Cephalexin safe for kittens?
Cephalexin can be used in kittens over 6 weeks of age at appropriate weight-based doses. Kittens may be more susceptible to GI side effects. Always consult your veterinarian before giving any antibiotic to a kitten.
What if I miss a dose of Cephalexin for my cat?
Give the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and resume the regular schedule. Do not double dose. Maintaining consistent blood levels is important for antibiotic effectiveness.
Does Cephalexin interact with other cat medications?
Cephalexin may interact with probenecid (increases drug levels), aminoglycosides (increased kidney risk), and anticoagulants. Always inform your vet of all medications your cat is taking, including supplements and over-the-counter products.
How should I store Cephalexin for my cat?
Store Cephalexin at room temperature (68–77°F / 20–25°C) in a dry place away from light. Keep the container tightly closed. Discard any unused medication after the treatment course is complete. Do not flush down the toilet.
