Cetylev (acetylcysteine) effervescent tablets for oral solution is an antidote for acetaminophen overdose indicated to prevent or lessen hepatic (liver) injury after ingestion of a potentially hepatotoxic quantity of acetaminophen in patients with acute ingestion or from repeated supratherapeutic ingestion. Common side effects of Cetylev include:

The loading dose of Cetylev is140 mg/kg administered orally. The maintenance dose of Cetylev is 70 mg/kg repeated every 4 hours for a total of 17 doses. Cetylev may interact with other drugs. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant before taking Cetylev. Both acetaminophen and acetylcysteine cross the placenta. Delaying treatment in pregnant women with acetaminophen overdose and potentially toxic acetaminophen plasma levels may increase the risk of harm to a fetus. It is unknown if Cetylev passes into breast milk. Consult your doctor before breastfeeding.

The following adverse reactions are described, or described in greater detail, in other sections of the labeling:

  • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]
  • Risk for Upper Gastrointestinal Hemorrhage [see WARNINGS AND PRECAUTIONS]

The most common adverse reactions have been identified from clinical studies or postmarketing reports of acetylcysteine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The most common adverse reactions were nausea, vomiting, other gastrointestinal symptoms, and rash with or without fever.
