Foxglove poisoning

Poisoning may also occur from taking more than the recommended amounts of medicines made from foxglove.

Poison Control

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 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

The provider will measure and monitor person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive:

  • Activated charcoal
  • Blood and urine tests
  • Breathing support
  • Chest x-ray
  • EKG (electrocardiogram or heart tracing)
  • Fluids through a vein (IV)
  • Laxatives
  • Medicines to treat symptoms, possibly including an antidote to help reverse the effects of the poison
  • Tube through the mouth into the stomach to wash out the stomach (gastric lavage)

Outlook (Prognosis)

How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.

Symptoms last for 1 to 3 days and may require a hospital stay. Death is unlikely.

DO NOT touch or eat any plant with which you are not familiar. Wash your hands after working in the garden or walking in the woods.
