Call emergency services for:
And for anyone, someone who:
Seek prompt medical care if there is repeated vomiting, inability to keep fluids down, worsening throat pain, persistent eye symptoms after rinsing, unusual drowsiness, or signs of dehydration.
Supervise young children in the bath and empty bathwater promptly.
Arrange routine medical follow-up if digestive symptoms do not settle, skin irritation continues, or pain with urination persists after the bubble bath product has been stopped.
A clinician can look for other causes, such as dermatitis or infection, without assuming the soap is responsible.
The article also says
A person with no symptoms or only brief mild stomach upset may not need an in-person visit after a poison center has reviewed the exposure.
Follow the poison specialist’s instructions and observe for new symptoms during the period they recommend.
To help prevent another exposure, keep bubble bath products in their original containers and store them out of children’s sight and reach.
Close the cap after each use.
Never transfer bath products into cups, beverage bottles, or food containers.
