Information on cefditoren pivoxil overdosage in humans is not available. However, with other β-lactam antibiotics, adverse effects following overdosage have included nausea, vomiting, epigastric distress, diarrhea, and convulsions. Hemodialysis may aid in the removal of cefditoren from the body, particularly if renal function is compromised (30% reduction of plasma concentrations following 4 hours of hemodialysis). Treat overdosage symptomatically and institute supportive measures as required.
In acute animal toxicity studies, cefditoren pivoxil when tested at the limit oral doses of 5100 mg/kg in rats and up to 2000 mg/kg in dogs did not exhibit any health effects of concern. Certain effects, such as diarrhea and soft stool lasting for a few days were observed in some animals as expected with most oral antibiotics due to inhibition of intestinal microflora.
