The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

The person may receive:

  • Activated charcoal
  • Breathing support, including tube through the mouth into the lungs, and breathing machine (ventilator)

Outlook (Prognosis)

How well someone does depends on how much myristica oil they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.

Hallucinations, anxiety and other psychiatric symptoms, and visual problems are most common in severe overdoses. Deaths have been reported, but only very rarely.
