Is any of this happening?
Be seen today
Contact a poison centre immediately after any suspected swallowing of eucalyptus oil.
This applies even when there are no symptoms or the amount seems small.
A poison specialist can judge the risk using the product, concentration, age, symptoms, and time since exposure.
Breathing difficulty, marked drowsiness, or worsening symptoms require urgent help rather than routine follow-up.

Does any of this apply?
Book an appointment
Arrange routine medical review if redness, pain, coughing, or other irritation does not settle.
And for anyone, someone who:
is having side effects from a medicine, or is struggling to take it as prescribed
The article also says
Do not let a drowsy or confused person drive.
Bring the product container to the hospital if it can be collected safely.
For skin or eye exposure, obtain poison-centre advice and rinse the affected area.
Every sign above is quoted from the sofidex article on Eucalyptus oil overdose. If you are not sure, err upward — it is always reasonable to be checked.
