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
Take the container to the hospital with you, if possible.
The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may be done include:
- Blood and urine tests
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
Treatment may include:
- Fluids through a vein (by IV)
- Medicine called an antidote to reverse the effects of the poison and treat symptoms, such as sodium bicarbonate or lidocaine
- Activated charcoal
- Breathing support, including a tube through the mouth and breathing machine (ventilator)
How well a person does depends on how quickly they receive treatment. The sooner the treatment, the greater the chance of recovery.
An overdose of desipramine hydrochloride can be very serious. 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.
