Keflex antibiotics are used in the management of the following infections, when produced by susceptible strains of the microorganisms named below:

- Infections of the respiratory tract due to Streptococcus pneumoniae and Streptococcus pyogenes. Penicillin is the usual medication prescribed in the therapy and prevention of streptococcal infections, including the prophylaxis of rheumatic fever. Keflex is generally valuable in the eradication of streptococci from the upper respiratory tract; however, significant data establishing the efficacy of Keflex in the subsequent prevention of rheumatic fever are not obtainable at present.

- Otitis media due to Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, and Moraxella catarrhalis

- Skin and skin structure infections due to Staphylococcus aureus and/or Streptococcus pyogenes

- Bone infections produced by Staphylococcus aureus and/or Proteus mirabilis

- Genitourinary tract infections, for example acute prostatitis, due to Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae

Tests related to culture and sensitivity should be completed before and during therapy with Keflex antibiotics. Tests of the renal function should be performed when recommended.

hinder the development of drug-resistant bacteria and preserve the effectiveness of Keflex antibiotics and other antibacterial drugs, Keflex should be used only to cure or prevent infections that are demonstrated or strongly assumed to be caused by sensitive bacteria.

Keflex antibiotics are administered orally.

The adult dosage ranges from 1 to 4 g daily in divided doses. The 333 mg and 750 mg forms should be administered in such a way that the daily dose is within 1 to 4 grams in one day. The usual dose for adults 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 treatment should be sustained for 7 to 14 days. For more grave infections or infections caused by less responsive microorganisms, an increased dosage of Keflex antibiotics may be necessary. If daily doses of Keflex antibiotics greater than 4 g are necessary, parenteral cephalosporins, in correct doses, should be considered.

The normal recommended daily dosage of Keflex antibiotics for pediatric patients is 25 to 50 mg/kg in a number of doses. For streptococcal pharyngitis in patients 1 year of age or older and for skin and skin structure infections, the total daily dose may be divided and administered in 2 divided doses. In grave infections, the dosage may be doubled.

In the treatment of otitis media, clinical studies have revealed that a dosage of 75 to 100 mg/kg/day in 4 divided doses is required.

In the treatment of ?-hemolytic streptococcal infections, a therapeutic dosage of Keflex antibiotics should be taken for at least 10 days.
