What to Expect at the Emergency Room
Take the container with you to the hospital, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may be done include:
- Blood and urine tests
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
- Tube down the windpipe and lungs to look for damage and burns (bronchoscopy)
Treatment may include:
- Fluids through a vein (by IV)
- Medicine to treat symptoms
- Activated charcoal
- Breathing support, including tube through the mouth into the lungs and connected to a breathing machine (ventilator)
How well someone does depends on the amount of peppermint oil swallowed and how quickly treatment is received. The faster medical help is given, the better the chance is for recovery.
Survival past 48 hours is often a good sign that recovery will occur. If the kidneys are damaged, they may take several months to heal. Long-term injury to the lungs can also occur.
