Before Calling Emergency
Determine the following information:
- the patient’s age, weight, and condition
- the name of the product (ingredients and strengths if known)
- the time it was swallowed
- the amount swallowed
- if the medication was prescribed for the patient
Poison Control, or a local emergency number
They will instruct you if it is necessary to take the patient to the hospital. See Poison Control centers for telephone numbers and addresses. Take the container with you to the emergency room.
What to expect at the emergency room
Some or all of the following procedures may be performed:
- Induce emesis unless seizures are imminent.
- Administer activated charcoal.
- Administer a laxative.
- Use gastric lavage.
- Treat the symptoms.
If the patient survives the first 24 hours, survival is likely. Few patients actually die from an antihistamine overdose.
