Have this information ready:

• The person's age, weight, and condition
• The name of the medicine, and strength, if known
• When it was swallowed
• The amount swallowed
• If the medicine was prescribed for the person

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline 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.

Take the container with you to the hospital, if possible.

Your provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

Tests may include:

• Blood and urine tests
• Chest x-ray
• CT scan (advanced imaging) of the brain for neurologic symptoms
• Electrocardiogram (ECG)

Treatment that may be done may include:

• Breathing support, including oxygen, tube through the mouth into the lungs, and breathing machine (ventilator)
• Fluids through a vein (IV)
• Laxative
• Medicines to reverse the effects of the drug and treat symptoms

With proper care, full recovery is likely. But people with aplastic anemia (suppression of red blood cell production by the bone marrow), those who develop breathing problems or seizures and subsequent complications, or those who overdose on multiple different substances may not recover fully.
