What special precautions should I follow?

• Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefadroxil monohydrate, and may range in severity from mild diarrhea to fatal colitis. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
• Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
• Cefadroxil monohydrate should be used with caution in the presence of markedly impaired renal function. In patients with known or suspected renal impairment, careful clinical observation and appropriate laboratory studies should be made prior to and during therapy.
• Prescribing cefadroxil monohydrate in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
• Prolonged use of cefadroxil monohydrate may result in the overgrowth of nonsusceptible organisms. Careful observation of the patient is essential. If superinfection occurs during therapy, appropriate measures should be taken.
• Cefadroxil monohydrate should be prescribed with caution in individuals with history of gastrointestinal disease particularly colitis.
• Patients should be counseled that antibacterial drugs including cefadroxil capsules should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold).
• Skipping doses or not completing the full course of therapy may

(1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefadroxil capsules or other antibacterial drugs in the future.

• Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued.
• Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.
• Caution should be exercised when cefadroxil monohydrate is administered to a nursing mother.
