Poison Control, or a Local Emergency Number
The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national 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. See: Poison control center - emergency number
What to Expect at the Emergency Room
The health care provider will check your temperature, pulse, breathing rate, and blood pressure. An intravenous (IV) line will be placed into a vein. Lab tests, including an arterial blood gas test, will be done. Treatment depends on the amount of aspirin, the time you swallowed it, and your overall condition when you reach the emergency room. You may receive: - Fluids
- Activated charcoal to soak up aspirin in the stomach
- Laxative to cause bowel movements that help remove aspirin and charcoal from the body
Other medicines may be given through a vein, including potassium salt and sodium bicarbonate, which helps the body remove aspirin that has already been digested. If these treatments do not work or the overdose is extremely severe, hemodialysis may be needed to remove aspirin from your blood. Very rarely, a breathing machine may be needed. But many poisoning experts think this causes more harm than good, so it is only used as a very last resort.
Prognosis (Expectations)
Taking more than 150mg/kg of aspirin can have serious and even deadly results if untreated. For a small adult, that's roughly equal to taking 20 tablets containing 325mg aspirin. Much lower levels can affect children. If treatment is delayed or the overdose is large enough, symptoms will continue to get worse. Breathing becomes extremely fast or may stop. Seizures, high fevers, or death may occur. How well you do depends greatly on how much aspirin your body has absorbed -- and how much is flowing through your blood. If you take a large amount of aspirin but come quickly to the emergency room, treatments may help keep your blood levels of aspirin very low. If you do not get to the emergency room fast enough, the level of aspirin in your blood can become dangerously high.
