Poisoning is a medical emergency that can happen by accident or, less commonly, because another person deliberately exposes you to a harmful substance. Knowing how to respond in the first few minutes can limit damage to the body and may save a life. This article explains what poisoning is, how to recognize it, what to do right away, what to avoid, and how to get help if you believe someone has intentionally poisoned you.
What counts as poisoning
A poison is any substance that can harm or kill a person if it is swallowed, breathed in, absorbed through the skin, or gotten into the eyes. Poisoning can come from household chemicals, medications taken in the wrong amount, pesticides, spoiled food, carbon monoxide gas, plants, or drugs. It can be accidental, such as a child swallowing pills, or intentional, such as someone tampering with food or a drink.
Signs that may point to poisoning
Poisoning symptoms vary depending on the substance, but common warning signs include:
- Burns or redness around the mouth and lips
- Breath that smells unusual, such as like chemicals or gasoline
- Nausea, vomiting, or stomach pain
- Confusion, drowsiness, or sudden change in behavior
- Difficulty breathing
- Seizures or loss of consciousness
Poisoning symptoms can look similar to other conditions, such as a stroke, seizure disorder, or low blood sugar, so it is easy to miss at first. If something feels wrong after eating, drinking, or being exposed to a chemical, it is safer to seek help than to wait and see.
Immediate steps if you suspect poisoning
Call emergency services right away if the person:
- Has collapsed or stopped breathing
- Is having a seizure
- Cannot be woken up
- Is having serious trouble breathing
- Is uncontrollably restless or agitated
If the person is stable and alert, the next steps depend on how the poison entered the body.
Swallowed poison
Do not induce vomiting. Many substances cause more damage coming back up than they did going down, and vomiting can also lead to choking. If the substance swallowed is burning or irritating and the person is awake and able to swallow safely, a small amount of water or milk may be given [only after a qualified medical practitioner has authorised so, be mindful of any allegies the person may have]. Contact a poison control center immediately for further instructions.
Poison on the skin
Remove any clothing that the poison touched. Rinse the affected skin with running water for 15 to 20 minutes.
Poison in the eyes
Rinse the eyes with lukewarm running water for 15 to 20 minutes, holding the eyelid open. Remove contact lenses if this can be done quickly.
Inhaled poison, including gas or fumes
Move the person to fresh air right away. If carbon monoxide poisoning is suspected, everyone should leave the building immediately and call emergency services from outside.
What not to do
- Do not try to make the person vomit unless a poison control expert specifically tells you to.
- Do not give anything by mouth to someone who is unconscious.
- Do not use activated charcoal, ipecac syrup, or any home remedy on your own. These are outdated or dangerous when used without medical guidance.
- Do not try to neutralize the poison with vinegar, lemon juice, or any other substance unless instructed by a medical professional.
- Do not wait for symptoms to appear before seeking help. Some poisons take time to show effects, and early treatment matters.
Getting expert help
In the United States, Poison Help can be reached at 1-800-222-1222, 24 hours a day, free and confidential. Trained nurses, pharmacists, and doctors staff these lines and can tell you whether home observation is enough or whether emergency care is needed. If you are outside the United States, look up your country’s or region’s poison control or emergency number in advance and keep it somewhere visible, such as on a refrigerator or saved in your phone.
When you call, try to have ready:
- The person’s age and approximate weight
- What the substance was, and the container or label if available
- How much was taken and when
- Any symptoms the person is having
If you believe someone has deliberately poisoned you
This situation is frightening, but there are practical steps you can take.
- Get medical care first. Go to an emergency department or call emergency services. Tell the medical team you suspect intentional poisoning so they can run the right tests and preserve evidence such as blood or urine samples.
- Do not eat or drink anything else from the same source. Keep the suspected food, drink, or container if it is safe to do so, since it may be tested later.
- Try to remember details. Note what you ate or drank, when, where, and who had access to it. Write this down as soon as you can, since memory can fade quickly, especially if you feel unwell.
- Contact the police. Intentional poisoning is a criminal act in most places. Medical staff can often help coordinate this if you are not able to do it yourself.
- Consider your immediate safety. If you believe the person who poisoned you may try again or may cause further harm, tell hospital staff, a trusted person, or the police so a safety plan can be put in place.
- Ask for support afterward. Being deliberately poisoned is traumatic. It is reasonable to want to speak with a counselor or therapist afterward, in addition to any legal steps.
Reducing the risk of poisoning at home
- Store medicines and chemicals in their original containers, out of reach of children, and locked if possible.
- Never mix cleaning products together.
- Install a carbon monoxide detector if you use gas appliances or have an attached garage.
- Keep the poison control number saved in your phone and posted at home.
