INITIAL U.S. APPROVAL: 1963
INDICATIONS AND USAGE
CETYLEV is an antidote for acetaminophen overdose indicated to prevent
or lessen hepatic injury after ingestion of a
potentially hepatotoxic quantity of acetaminophen in patients with
acute ingestion or from repeated supratherapeutic
ingestion. (1)
DOSAGE AND ADMINISTRATION
Pre-Treatment Assessment Following Acute Ingestion (2.1):
Obtain a plasma or serum sample to assay for acetaminophen
concentration at least 4 hours after ingestion.
If the time of acetaminophen ingestion is unknown:
Administer a loading dose of CETYLEV immediately.
Obtain an acetaminophen concentration to determine the need for
continued treatment.
If the acetaminophen concentration cannot be obtained (or is
unavailable or uninterpretable) within the 8-hour time
interval after acetaminophen ingestion or there is clinical evidence
of acetaminophen toxicity:
Administer a loading dose of CETYLEV immediately and continue
treatment for a total of 17 doses.
If the patient presents more than 8 hours after ingestion and the time
of acute acetaminophen ingestion is known:
Administer a loading dose of CETYLEV immediately.
Obtain acetaminophen concentration to determine need for continued
treatment.
If the patient presents less than 8 hours after ingestion and the time
of acute acetaminophen ingestion is known and the
acetaminophen concentration is known:
Use the Rumack-Matthew nomogram (Figure 1) to determine whether or not
to initiate treatment with CETYLEV.
