Eucalyptus oil can be harmful in large amounts.
Eucalyptus oil is an ingredient in many over-the-counter products, including some:
- Medicated rubs and liniments
- Diaper rash creams
- Inhalers to relieve nasal congestion
- Medicine for sore gums, mouth, and throat
Other products may also contain eucalyptus oil.
Below are symptoms of a eucalyptus oil overdose in different parts of the body.
AIRWAYS AND LUNGS
EYES, EARS, NOSE, THROAT, AND MOUTH
HEART AND BLOOD
MUSCLES AND JOINTS
- Redness and swelling (from the oil touching the skin)
STOMACH AND INTESTINES

If the oil is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
What to Expect at the Emergency Room
Take the container to the hospital with you, if possible.
The health care 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
- Blood and urine tests
- Breathing support, including tube down the windpipe to help with breathing and protect the windpipe and lungs from getting eucalyptus oil into them when vomiting
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)
- Medicine to help reverse the effects of the oil
- Tube through the nose into the stomach to wash out the stomach (gastric lavage)
- Tube down the throat and into the lungs to assess damage (bronchoscopy)
Survival past 48 hours is usually a good sign that recovery will occur. If any damage to the kidneys has occurred, it may take several months to heal. Drowsiness may persist for several days.
