Pregnancy & Breast-feeding
FDA Pregnancy Category B
Breast-feeding
Other cephalosporins are distributed into breast milk, usually in low concentrations. However, problems in humans have not been documented to date.
Precaution
Pediatrics
Lower metabolic and/or renal clearance of cephalosporins, with resulting prolonged half-life, has been reported in newborn infants. Appropriate studies on the relationship of age to the effects of these cephalosporins have not been performed in the pediatric population. However, no pediatrics-specific problems have been documented to date.
Geriatrics
Cephaiosporins have been used in the geriatriC population, and no geriatrics-specific problems have been documented to date. However, elderly patients are more likely to have an age-related decrease in renal function, which may require an adjustment in dosage andlor dosing interval in patients receiving cephalosporins.
Dental
Long-term therapy with cephalosporins may allow for the overgrowth of Candida albicans, resulting in oral candidiasis.
