Poison Control

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.

What to Expect at the Emergency Room

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate.

The patient may receive:

  • Activated charcoal
  • Breathing support, including a tube through the mouth and breathing machine (ventilator)
  • Chest x-ray
  • EKG (heart tracing)
  • Fluids through a vein (by IV)
  • Laxative
  • Medicine called an antidote (sodium bicarbonate) to reverse the effects of the medication
  • Tube through the mouth into the stomach to empty the stomach (gastric lavage)

Outlook (Prognosis)

Amitriptyline and perphenazine can be an extremely serious overdose.

Patients who swallow an excessive amount of this drug are almost always admitted to the hospital.

How well a patient does depends on how much of the drug was swallowed and how quickly treatment was received. The faster a patient gets medical help, the better the chance of recovery. Complications such as pneumonia, muscle damage from lying on a hard surface for a long period of time, or brain damage from lack of oxygen may result in permanent disability. Death can occur.
