To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefaclor extended-release tablets USP and other antibacterial drugs, cefaclor extended-release tablets USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. The safety and effectiveness of cefaclor extended-release tablets in treating some of the indications and pathogens for which other formulations of cefaclor are approved have NOT been established. When administered at the recommended dosages and durations of therapy, cefaclor extended-release tablets are indicated for the treatment of patients with the following mild to moderate infections when caused by susceptible strains of the designated organisms. (See and CLINICAL STUDIES sections.) Acute bacterial exacerbations of chronic bronchitis due to Haemophilus influenzae (excluding ß-lactamase-negative, ampicillin-resistant isolates), Moraxella catarrhalis, or Streptococcus pneumoniae . NOTE: In view of the insufficient numbers of isolates of ß-lactamase-producing isolates of Haemophilus influenzae that were obtained from clinical trials with cefaclor extended-release tablets for patients with acute bacterial exacerbations of chronic bronchitis, it was not possible to adequately evaluate the effectiveness of cefaclor extended-release tablets for bronchitis known, suspected, or considered potentially to be caused by ß-lactamase-producing H. influenzae . Pharyngitis and tonsillitis due to Streptococcus pyogenes . NOTE: Only penicillin by the intramuscular route of administration has been shown to be effective in the prophylaxis of rheumatic fever. Cefaclor extended-release tablets are generally effective in the eradication of S. pyogenes from the oropharynx; however, data establishing the efficacy of cefaclor extended-release tablets for the prophylaxis of subsequent rheumatic fever are not available. Uncomplicated skin and skin and structure infections due to Staphylococcus aureus (methicillin-susceptible only)....

The absorption of cefaclor extended-release tablets is enhanced when it is administered with food. (See CLINICAL PHARMACOLOGY .) Therefore, cefaclor extended-release tablets should be administered with meals (i.e., at least within one hour of eating) . The extended-release tablets should not be cut, crushed, or chewed. See for information about patients for whom cefaclor extended-release tablets are indicated. NOTE: 500 mg BID of cefaclor extended-release tablets is clinically equivalent to 250 mg TID of cefaclor immediate-release as a capsule in those indications listed in the section of this label. 500 mg BID of cefaclor extended-release tablets is NOT equivalent to 500 mg TID of other cefaclor formulations. Adults (age 16 years and older): Type of Infection (as qualified in the section of this labeling) Total Daily Dose Dose and Frequency Duration Acute Bacterial Exacerbations of Chronic Bronchitis due to H. influenzae (non-ß-lactamase-producing strains only). Moraxella catarrhalis (including ß-lactamase-producing strains), or Streptococcus pneumoniae (See .) 1000 mg 500 mg q 12 hours 7 days Pharyngitis and/or tonsillitis due to S. pyogenes 750 mg 375 mg q 12 hours 10 days Uncomplicated Skin and Skin Structure Infections due to S. aureus (methicillin-susceptible strains) (See .) 750 mg 375 mg q 12 hours 7 to 10 days Elderly patients with normal renal function do not require dosage adjustments.

Clinical Trials There were 3272 patients treated with multiple doses of cefaclor extended-release tablets in controlled clinical trials and an additional 211 subjects in pharmacology studies. There were no deaths in these trials thought to be related to toxicity from cefaclor extended-release tablets. Treatment was discontinued in 1.7% of patients due to adverse events thought to be possibly or probably drug-related. The following adverse clinical and laboratory events were reported during the cefaclor extended-release tablets clinical trials conducted in North America at doses of 375 mg or 500 mg BID; however, relatedness of the adverse events to the drug was not assigned by clinical investigators during the trials (see TABLES 4 and 5 ). Table 4: ADVERSE CLINICAL EVENTS - CEFACLOR EXTENDED-RELEASE TABLETS MULTIPLE DOSE DOSING REGIMENS CLINICAL TRIALS - NORTH AMERICA (n = 1400) Incidence Equal to or Greater Than 1% Event Incidence Headache 4.9% Rhinitis 3.9% Diarrhea 3.8% Nausea 3.4% Vaginitis n = 934 for these events (subset of female participants). 2.4% Vaginal Moniliasis 2.2% Abdominal Pain 1.6% Cough Increased 1.5% Pharyngitis 1.4% Pruritus 1.4% Back Pain 1.0% occurring during the clinical trials with cefaclor extended-release tablets with an incidence of less than 1% but greater than 0.1% included the following (listed alphabetically): Accidental injury, anorexia, anxiety, arthralgia, asthma, bronchitis, chest pain, chills, congestive heart failure, conjunctivitis, constipation, dizziness, dysmenorrhea, dyspepsia, dysuria, ear pain, edema, fever, flatulence, flu syndrome, gastritis, infection, insomnia, leukorrhea, lung disorder, maculopapular rash, malaise, menstrual disorder, myalgia, nausea and vomiting, neck pain, nervousness, nocturia, otitis media, pain, palpitation, peripheral edema, rash, respiratory disorder, sinusitis, somnolence, surgical procedure, sweating, tremor, urticaria, vomiting. NOTE: One case of serum-sickness-like reaction was reported among the 3272 adult patients treated with cefaclor extended-release tablets during the controlled clinical trials. These reactions have also been reported with the use of cefaclor in other oral formulations and are seen more frequently in pediatric patients than in adults....

Cefaclor extended-release tablets are contraindicated in patients with known hypersensitivity to cefaclor and other cephalosporins.
