Cephalexin is a broad-spectrum antibiotic available as capsules or suspension used to treat bacterial infections of the skin, urinary tract, respiratory tract, bones, and joints. Cephalexin requires a prescription from your veterinarian.
Cats and Dogs
Cephalexin is a cephalosporin antibiotic. Cephalosporin antibiotics suppress the growth of micro-organisms such as bacteria, fungi, or protozoa.
In the event of an allergic reaction - such as shortness of breath, rash, hives, vomiting, diarrhea, mucous or blood in the stool, swelling of the lips, tongue, or face, and unusual bleeding or bruising - contact your veterinarian immediately.
Cephalexin is an antibiotic belonging to a class of drugs called cephalosporins that fight bacteria in the body. Cephalexin can be used to treat infections such as bronchitis as well as ear, skin, and urinary tract infections. Cephalexin may also be used for purposes other than those listed.
Tell your veterinarian if your pet has ever had an allergic reaction to another penicillin or to a cephalosporin. Tell your veterinarian if your pet has kidney disease, or a stomach or intestinal disease. Tell your veterinarian if your pet is pregnant or lactating. Cephalexin liquid suspension contains sucrose which may affect the treatment of diabetic pets.
Give this medication exactly as directed by your veterinarian. Cephalexin can be given with or without food. Give all of the cephalexin even if your pet appears to be better. Symptoms may improve before the infection is completely treated. Store capsules at room temperature away from moisture or heat. Store the liquid suspension in the refrigerator. Discard any unused liquid suspension after 14 days.
Give the missed dose as soon as you remember, then try to evenly space the rest of the doses for that day until you can return to a normal schedule. Do not give a double dose unless otherwise directed by your veterinarian.
There are no restrictions on food or activity during treatment with cephalexin unless otherwise directed by your veterinarian.
Stop giving cephalexin and seek emergency veterinary medical care in the event of an allergic reaction (shortness of breath; hives; swelling of the lips, tongue, or face; rash; or fainting), severe nausea, vomiting or diarrhea, mucus or blood in the stool, or unusual bleeding or bruising. Other less serious side effects such as mild nausea, diarrhea, or yeast infection may be more likely to occur. Continue to give cephalexin and notify your veterinarian if these symptoms occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.
Before giving cephalexin, tell your veterinarian if your pet is being given another antibiotic (for the same or a different infection), probenecid, or a loop diuretic such as furosemide or warfarin. You may not be able to give cephalexin or you may need to have the dosage adjusted. Drugs other than those listed here may also interact with cephalexin. Talk to your veterinarian or pharmacist before giving any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.
Your pharmacist has additional information about cephalexin written for health professionals that you may read.
Call your veterinarian for medical advice about any side effects to your pet. You may report side effects to the FDA at 1-800-FDA-1088.
