Most important information about Keflex
DO NOT USE if you are allergic to cephalosporins.
BEFORE USING THIS MEDICATION, tell your doctor or pharmacist if you are pregnant, planning to become pregnant, or are breastfeeding; or if you are taking, will be taking or stop taking any prescription or nonprescription medicine; if you are allergic to penicillins; or if you have any other medical conditions (eg, diabetes, kidney or liver disease, gastrointestinal disease).
How It Works
Keflex medication is part of the family of cephalosporin antibiotics. Cephalexin is a semisynthetic cephalosporin antibiotic intended for oral administration. Cephalexin works by stopping the growth of bacteria.
This antibiotic treats only bacterial infections. It will not work for virus infections (common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
Keflex is indicated in the treatment of respiratory tract infections, inner ear infections, skin and skin structure infections, bone infections, and urinary tract infections caused by bacteria.
Keflex is administered orally.
- The adult dosage ranges from 1 to 4 g daily in divided doses. The 333 mg and 750 mg strengths should be administered such that the daily dose is within 1 to 4 grams per day. The usual adult dose is 250 mg every 6 hours. For the following infections, a dosage of 500 mg may be administered every 12 hours: streptococcal pharyngitis, skin and skin structure infections, and uncomplicated cystitis in patients over 15 years of age. Cystitis therapy should be continued for 7 to 14 days. For more severe infections or those caused by less susceptible organisms, larger doses may be needed. If daily doses of Keflex greater than 4 g are required, parenteral cephalosporins, in appropriate doses, should be considered.
- The usual recommended daily dosage for pediatric patients is 25 to 50 mg/kg in divided doses. For streptococcal pharyngitis in patients over 1 year of age and for skin and skin structure infections, the total daily dose may be divided and administered every 12 hours.
In severe infections, the dosage may be doubled.
In the therapy of otitis media, clinical studies have shown that a dosage of 75 to 100 mg/kg/day in 4 divided doses is required.
In the treatment of ß-hemolytic streptococcal infections, a therapeutic dosage of Keflex should be administered for at least 10 days.
Symptoms of oral overdose may include nausea, vomiting, epigastric distress, diarrhea, and hematuria. If other symptoms are present, it is probably secondary to an underlying disease state, an allergic reaction, or toxicity due to ingestion of a second medication.
If an overdose is suspected contact your local Poison Control Center. Unless 5 to 10 times the normal dose of cephalexin has been ingested, gastrointestinal decontamination should not be necessary. Protect the patient's airway and support ventilation and perfusion. Meticulously monitor and maintain, within acceptable limits, the patient's vital signs, blood gases, serum electrolytes, etc. Absorption of drugs from the gastrointestinal tract may be decreased by giving activated charcoal, which, in many cases, is more effective than emesis or lavage; consider charcoal instead of or in addition to gastric emptying.
