Abstract

INTRODUCTIONParacetamol overdose is the most common drug overdose worldwide. To our knowledge, the maximum number of paracetamol tablets ingested reported in the literature is 45 g.

CLINICAL PICTUREWe describe a 21-year-old patient who acutely ingested 120 tablets, each 500 mg paracetamol (i.e., 60 g equivalent to 1200 mg/kg body weight) in a suicidal attempt. Our patient also drank 2 bottles of codeine-based cough syrup equivalent to 360 mg of codeine. At 6 hours post ingestion, her serum paracetamol level was 207 mg/L. The poor prognostic factors for paracetamol overdose in our patient included massive paracetamol ingestion (confirmed by blood levels), codeine co-ingestion and elevated serum amylase (189 U/L).

TREATMENTShe was treated with a 3-day modified regimen of intravenous N-acetylcysteine.

OUTCOMEThe liver function tests and the prothrombin time remained normal over the second and third day of admission and the patient was discharged without complications on the fifth day.

CONCLUSIONFrom this experience we feel that in very severe paracetamol poisoning, a modified regime of intravenous N- acetylcysteine for 3 days is safe and efficacious.
