Poisoning
What is Poisoning?
Poisoning happens when your body is exposed to a substance that causes harm. This can occur through swallowing, breathing, injecting, or absorbing something toxic through your skin. Poisons include medications, household chemicals, plants, carbon monoxide, food toxins, and drugs.
The severity of poisoning depends on the type of substance, the amount, and how quickly you get treatment. Some poisons act within minutes, while others take hours or days to cause symptoms. Young children and older adults face higher risks because their bodies process toxins differently.
Accidental poisoning is common in homes with young children who explore by putting things in their mouths. Medication overdoses, both accidental and intentional, also account for many poisoning cases. Quick recognition and response can save lives and prevent long-term damage.
Symptoms
- Nausea, vomiting, or diarrhea
- Stomach pain or cramping
- Dizziness, confusion, or drowsiness
- Difficulty breathing or shortness of breath
- Burns or redness around the mouth or skin
- Unusual odor on breath or clothing
- Seizures or loss of consciousness
- Rapid or irregular heartbeat
- Headache or blurred vision
- Sweating or drooling more than normal
Some poisons cause immediate symptoms, while others may not show effects for hours. If you suspect poisoning, seek emergency help right away even without obvious symptoms.

Causes and risk factors
Poisoning occurs when harmful substances enter your body in amounts that cause damage. Common causes include accidental medication overdoses, especially pain relievers or sedatives. Household cleaning products, pesticides, and automotive fluids are frequent culprits in home poisonings. Carbon monoxide from faulty heaters or car exhaust is a silent danger. Food poisoning from bacteria or toxins in contaminated food affects millions each year.
Children under age 6 face the highest risk of accidental poisoning from exploring their environment. Adults may experience poisoning from medication errors, mixing drugs with alcohol, or workplace chemical exposure. People with substance use disorders risk overdoses from illegal drugs or misused prescription medications. Older adults taking multiple medications may accidentally take wrong doses or harmful combinations.
How it's diagnosed
Diagnosing poisoning starts with identifying the substance involved. Emergency responders and doctors ask about what was swallowed, inhaled, or touched, and when exposure occurred. Physical exams check vital signs, breathing, and mental status. Blood and urine tests can detect specific toxins, drugs, or medications in your system.
Specialized toxicology testing identifies substances like dextromethorphan, opioids, or other drugs that may cause poisoning. LC/MS/MS urine testing is a sensitive method that detects even small amounts of certain medications or drugs. Talk to a doctor about specialized testing if you need toxicology screening. Poison control centers provide 24/7 guidance at 1-800-222-1222.
Treatment options
- Call 911 or Poison Control at 1-800-222-1222 immediately if poisoning is suspected
- Bring the substance container or label to the emergency room for identification
- Do not induce vomiting unless specifically instructed by medical professionals
- Activated charcoal may be given in hospitals to absorb certain poisons
- Antidotes are available for specific toxins like acetaminophen or opioids
- Supportive care includes IV fluids, oxygen, and monitoring of vital signs
- Stomach pumping may be needed if ingestion occurred very recently
- Dialysis can help remove certain poisons from the bloodstream
- Prevent future poisoning by storing medications and chemicals safely out of reach
- Install carbon monoxide detectors in your home near sleeping areas
Frequently asked questions
Call 911 immediately if the person is unconscious, having seizures, or having trouble breathing. For other situations, call Poison Control at 1-800-222-1222 right away. Do not wait for symptoms to worsen. Bring the substance container to the hospital if possible so medical staff can identify the poison.
Some poisons cause symptoms within minutes, while others take hours or even days. Carbon monoxide and cyanide act very quickly. Acetaminophen overdose may not cause obvious symptoms for 24 hours despite causing liver damage. Never wait for symptoms to seek help if you know exposure occurred.
Blood and urine tests can detect many common poisons including medications, drugs, and some chemicals. However, not all toxins show up on standard tests. Specialized toxicology panels can identify specific substances like dextromethorphan or opioids. Your doctor will order appropriate tests based on suspected exposure.
Food poisoning comes from bacteria, viruses, or toxins in contaminated food and usually causes digestive symptoms. Chemical poisoning involves exposure to household cleaners, medications, or industrial chemicals. Both require medical attention, but chemical poisoning often needs more urgent emergency care and may require antidotes.
No, do not induce vomiting unless a medical professional specifically tells you to. Vomiting can cause more harm with certain poisons, especially corrosive substances that can burn the throat twice. It can also lead to aspiration where poison enters the lungs. Always call Poison Control first.
Store all medications, cleaning products, and chemicals in locked cabinets out of children's reach. Keep products in original containers with labels. Install carbon monoxide detectors near bedrooms. Never call medicine candy when giving it to children. Dispose of expired medications properly at take-back locations.
Activated charcoal is a black powder given in emergency rooms to absorb certain poisons in the stomach before they enter the bloodstream. It works best when given within one hour of ingestion. It does not work for all poisons and is not effective for alcohol, acids, or alkalis. Medical professionals decide when to use it.
Many people recover fully from poisoning with prompt treatment, especially if caught early. Recovery depends on the type of poison, the amount, and how quickly treatment began. Some poisons can cause permanent organ damage, particularly to the liver, kidneys, or brain. Quick action improves outcomes significantly.
Pain relievers like acetaminophen and ibuprofen are leading causes of medication poisoning. Cleaning products, especially bleach and ammonia, cause many chemical exposures. Laundry detergent pods are dangerous for children. Carbon monoxide from faulty furnaces is a silent killer. Antifreeze and windshield washer fluid also cause serious poisonings.
Call 911 and go to the emergency room if the person is unconscious, not breathing, having seizures, or showing severe symptoms. Call Poison Control at 1-800-222-1222 for guidance if the person is awake and stable. They can tell you whether emergency care is needed or if home monitoring is safe.
