|Prompt=A 27 year old female patient is brought to the emergency department (ED) with severe abdominal pain and nausea. Her vital signs show a temperature of 36.8 degrees C (98.24 degrees F), a heart rate of 88 bpm, and a blood pressure measuring 128/78 mmHg. Her husband arrives to the ED shortly and informs the physician that the patient had ingested more than 20 tables of acetaminophen 5 hours before admission in an attempt to commit suicide. The physician decides to administer a medication to reduce the effect of toxicity. What is another indication for the same medication to be used for this patient's condition? | |Prompt=A 27 year old female patient is brought to the emergency department (ED) with severe abdominal pain and nausea.

|Explanation=The patient is presenting with acetaminophen (paracetamol) toxicity. When patients present with delay, awaiting the serum levels of acetaminophen may not be very helpful. As such, giving N-acetylcysteine before the serum levels of acetaminophen are available becomes necessary. Symptoms of acetaminophen overdose are generally non-specific, such as abdominal pain and nausea. | |Explanation=The patient is presenting with acetaminophen (paracetamol) toxicity.

Explanation | [[Explanation::The patient is presenting with acetaminophen (paracetamol) toxicity. When patients present with delay, awaiting the serum levels of acetaminophen may not be very helpful. As such, giving N-acetylcysteine before the serum levels of acetaminophen are available becomes necessary. Symptoms of acetaminophen overdose are generally non-specific, such as abdominal pain and nausea.
N-acetylcysteine is an anti-oxidant that may be used to reduce the effect of acetaminophen (paracetamol) toxicity by the regeneration of glutathione and reduction of toxic reactive oxygen species (ROS). N-acetylcysteine is also a mucolytic that is usuaully use in patients with cystic fibrosis. Educational Objective: N-acetylcysteine is used as an antidote to reduce the toxicity of acetaminophen (paracetamol). It is also a mucolytic used in patients with cystic fibrosis. |
