The first phase begins shortly after ingestion of a potentially toxic overdose and lasts for 12 to 24 hours. The patient may manifest signs of gastrointestinal irritability, nausea, vomiting, anorexia, diaphoresis, and pallor. The larger the overdose, the more likely it is that these symptoms are pres-ent. Coma or other evidence of central nervous system depression is usually not present unless the patient has taken a massive overdose or has also ingested central nervous system depressants, as may be the case in suicide attempts. Coma accompanied by severe metabolic acidosis has rarely been reported following acetaminophen overdose, but the loss of consciousness was thought to be secondary to the metabolic acidosis rather than the acetaminophen itself. In small children, spontaneous vomiting following a substantial overdose occurs frequently and may play a role in the reduced risk of toxicity in children. However, these symptoms are not unique to acetaminophen, and unless the possibility of acetaminophen overdose is considered during this early phase, it may be overlooked. Many patients with early symptoms never progress beyond the first phase and recover without additional problems.
