Never take a "wait-and-see" attitude when it comes to poison emergencies.
Seek immediate treatment. Call 911 if you are unsure of what to do.
If the patient (especially a child) swallowed something that might be dangerous or if the patient was exposed to a chemical or toxic substance, immediately call 911 or the Arizona Poison Control Center at 800-222-1222.
As for a scorpion sting, ID the scorpion and call the AZ poison control immediately or get to the hospital. If the problem is snake bite, DO NOT take the snake to the ER! If possible, note the snake's color, size, and head shape.
