The nephrotoxicity of aminoglycoside antibiotics such as gentamicin and tobramicin may be enhanced by any cephalosporin. Therefore, one should be cautious in concomitant use of these categories of drugs.
Cefaclor is contraindicated in patients with known allergy to the Cephalosporin group of antibiotics.
Gastro-intestinal: Diarrhoea, nausea and vomiting have been reported. Hypersensitivity: Allergic reactions such as eruptions, pruritis and urticaria have been observed. These reactions usually subside upon discontinuation of therapy. Serum sickness like reactions have been reported.
Haematological: Eosinophilia, thrombocytopenia, transient lymphocytosis and leucopenia may occur rarely. Hepatic: Transient hepatitis and cholestatic jaundice, slight elevation in AST, ALT or alkaline phosphate values have been reported rarely.
Renal: Reversible interstitial nephritis has occurred rarely, also slight elevations in blood urea or serum creatinine or abnormal urinalysis.
Central Nervous System: Reversible hyperactivity, nervousness, confusion, hypertonia, dizziness, hallucinations and somnolence have been reported rarely.
There are no adequate and well-controlled studies in pregnant women. This drug should be used during pregnancy only if clearly needed. Small amounts of Cefaclor have been detected in mother's milk. The effect on nursing infants is not known. Caution should be exercised when Cefaclor is administered to a nursing woman.
Cefaclor should be administered with caution in the presence of markedly impaired renal function. Dosage adjustments for patients with moderate or severe renal impairment are not usually required.
Symptoms: Nausea, vomiting, epigastric distress and diarrhoea would be anticipated.
Treatment: Unless 5 times the normal total daily dose has been ingested, gastrointestinal decontamination will not be necessary. General management may consist of supportive therapy.
