Identification
-
Cephalexin is an antibiotic that is in the cephalosporin class. This medication prevents bacteria from forming a protective cell wall, resulting in the death of the bacteria. Cephalexin is similar to penicillin in the way it fights bacteria, but has a wider range of protection against bacteria than penicillin.
Uses
-
Cephalexin may be used to treat conditions such as bacterial infections, skin infections, bone infections, wound infections, pneumonia and bladder infections. Cephalexin is not effective against parasitic infections (intestinal worms), fungi, mites or viruses.
Side Effects
-
There have been some side effects associated with the use of cephalexin. The most common side effect in dogs is vomiting shortly after the drug is administered. Other side effects may include diarrhea and allergic reaction to the medication. Cephalexin should not be used in dogs that have a known sensitivity to cephalosporin drugs or penicillin.
Dosing
-
Cephalexin is available in 250 mg and 500 mg tablets and capsules. It is also available in an oral suspension in the strength of 25 mg/ml and 50 mg/ml. The usual dose is 10 to 15 mg per each lb. of body weight every eight hours for dogs.
Considerations
-
Cephalexin is generally well tolerated and considered safe for use in dogs. Be sure to give your dog all of the medication for the duration of treatment as recommended by your veterinarian. Even if your dog is feeling better, this is an important step. Finishing all of the medication will help to prevent a relapse of his medical condition.
