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.

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
• Antidote (sodium bicarbonate)
• Breathing help, possibly artificial respiration
• Fluids
• Laxative
• Tube through the mouth into the stomach to empty the stomach (gastric lavage)

Expectations (prognosis)

Amitriptyline hydrochloride can be an extremely serious overdose.

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