How long does it take to recover from a Tylenol overdose?

In the United States, Tylenol (acetaminophen) overdoses are the predominant cause of acute liver failure. Fortunately, over 70% of people recover completely in three months, and more than 80% survive. Prognosis is best for those who receive Tylenol overdose treatment soon after an overdose occurs. These treatments typically include hospitalization, extensive blood tests, “antidote” medications, and liver transplantation.

What is NAC used for?

N-Acetylcysteine (NAC) has been widely-used as an “antidote” for Tylenol overdoses since the mid-1980s. NAC binds directly to NAPQI (the toxic metabolite of acetaminophen) and helps the body eliminate it in the bile. If NAC is given within 16 hours of an overdose, it can prevent acute liver failure. If liver failure has already occurred, administering NAC up to 48 hours after an overdose can still improve a patient’s chance of survival and lower the risk of multi-organ system failure.

What is the purpose of the Rumack-Matthew nomogram?

How to manage acetaminophen overdose?

Acetaminophen overdose can be effectively managed by focusing on a few basic principles. As in all cases of poisoning, healthcare providers should obtain a careful history and should have a high index of suspicion. When acetaminophen overdose is a possibility, an acetaminophen level should be obtained and antidotal therapy should be initiated as indicated in these guidelines. When acetylcysteine is administered soon after an overdose occurs, morbidity is significantly reduced and mortality virtually eliminated. The prognosis for patients with acetaminophen overdose is excellent, provided treatment is given expeditiously and appropriately.

How long does acetaminophen last?

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.

Does charcoal reduce acetaminophen?

Gastric decontamination should be carried out according to standard treatment guidelines. Activated charcoal reduces the peak serum con-centration of acetamino phen. This may reduce the 4 hour acetaminophen level and thereby decrease the number of patients requiring treatment with acetylcysteine. Activated charcoal may be given during the immedi-ate postingestion period, especially in the case of a mixed drug overdose. Data supporting the efficacy of activated charcoal beyond 2 hours after ingestion are limited. Administration of activated charcoal does not require a change in subsequent administration of oral or intravenous acetylcysteine therapy.

Is acetaminophen extended release?
