Indications and Usage

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cefadroxil Tablets and Cefadroxil Capsules and other antibacterial drugs, Cefadroxil Tablets and Cefadroxil capsules 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.Cefadroxil is indicated for the treatment of patients with infection caused by susceptible strains of the designated organisms in the following diseases:Urinary tract infections caused by E.

coli, P.

mirabilis, and Klebsiella species.Skin and skin structure infections caused by staphylococci and/or streptococci.Pharyngitis and/or tonsillitis caused by Streptococcus pyogenes (Group A beta-hemolytic Streptococci).Note: Only penicillin by the intramuscular route of administration has been shown to be effective in the prophylaxis of rheumatic fever.

Cefadroxil is generally effective in the eradication of streptococci from the oropharynx.

However, data establishing the efficacy of cefadroxil for the prophylaxis of subsequent rheumatic fever are not available.Note: Culture and susceptibility tests should be initiated prior to and during therapy.Renal function studies should be performed when indicated.
Infection -- Invasion of the host organism by microorganisms that can cause pathological conditions or diseases.

Communicable Diseases -- broad class of diseases whose causative agents may be passed between individuals in many different ways.

Urinary tract infection -- Inflammatory responses of the epithelium of the URINARY TRACT to microbial invasions. They are often bacterial infections with associated BACTERIURIA and PYURIA.

skin infection -- Skin diseases caused by bacteria, fungi, parasites, or viruses.

Unspecified Staphylococcus infection in conditions classified elsewhere and of unspecified site --

Pharyngitis -- Inflammation of the throat (PHARYNX).

Tonsillitis -- Inflammation of the tonsils, especially the PALATINE TONSILS but the ADENOIDS (pharyngeal tonsils) and lingual tonsils may also be involved. Tonsillitis usually is caused by bacterial infection. Tonsillitis may be acute, chronic, or recurrent.

Rheumatic Fever -- A febrile disease occurring as a delayed sequela of infections with group A hemolytic streptococci and characterized by multiple focal inflammatory lesions of the connective tissue structures, especially of the heart, blood vessels, and joints (polyarthritis), and by the presence of Aschoff bodies in the myocardium and skin. (Dorland, 27th ed)

Contraindications
Cefadroxil is contraindicated in patients with known allergy to the cephalosporin group of antibiotics.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

Immediate hypersensitivity -- Hypersensitivity reactions which occur within minutes of exposure to challenging antigen due to the release of histamine which follows the antigen-antibody reaction and causes smooth muscle contraction and increased vascular permeability.

Warnings

BEFORE THERAPY WITH CEFADROXIL IS INSTITUTED, CAREFUL INQUIRY SHOULD BE MADE TO DETERMINE WHETHER THE PATIENT HAS HAD PREVIOUS HYPERSENSITIVITY REACTIONS TO CEFADROXIL, CEPHALOSPORINS, PENICILLINS OR OTHER DRUGS.

IF THIS PRODUCT IS TO BE GIVEN TO PENICILLIN-SENSITIVE PATIENTS, CAUTION SHOULD BE EXERCISED BECAUSE CROSS-SENSITIVITY AMONG BETA-LACTAM ANTIBIOTICS HAS BEEN CLEARLY DOCUMENTED AND MAY OCCUR IN UP TO 10% OF PATIENTS WITH A HISTORY OF PENICILLIN ALLERGY.IF AN ALLERGIC REACTION TO CEFADROXIL OCCURS, DISCONTINUE THE DRUG.

SERIOUS ACUTE HYPERSENSITIVITY REACTIONS MAY REQUIRE TREATMENT WITH EPINEPHRINE AND OTHER EMERGENCY MEASURES, INCLUDING OXYGEN, INTRAVENOUS FLUIDS, INTRAVENOUS ANTIHISTAMINES, CORTICOSTEROIDS, PRESSOR AMINES, AND AIRWAY MANAGEMENT, AS CLINICALLY INDICATED.Pseudomembranous colitis has been reported with nearly all antibacterial agents, including cefadroxil, and may range from mild to life-threatening.

Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia.

Studies indicate that a toxin produced by Clostridium difficile is a primary cause of “antibiotic-associated colitis”.After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated.

Mild cases of pseudomembranous colitis usually respond to discontinuation of the drug alone.

In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug effective against Clostridium difficile.
