What to Do After a Poisoning or Chemical Exposure

A poisoning can happen when someone swallows, breathes, touches, or injects a harmful substance. Chemicals can also damage the eyes or skin without entering the rest of the body.

Possible poisons include medications, household cleaners, pesticides, gases, plants, alcohol, drugs, automotive products, cosmetics, and many other everyday substances.

Do not wait for symptoms to develop before asking for help. Some substances cause immediate symptoms, while others may not produce noticeable effects for several hours.

In the United States, call Poison Control at 1-800-222-1222 for immediate, expert guidance. The service is free, confidential, and available 24 hours a day. You can also use the official webPOISONCONTROL tool at Poison.org.

Call 911 immediately if the person collapses, has a seizure, has trouble breathing, or cannot be awakened.

Make Sure the Area Is Safe

Before helping, look for hazards such as:

  • Toxic fumes
  • Smoke
  • Chemical spills
  • Fire
  • Pesticides
  • Unlabeled containers
  • Powder or liquid on clothing
  • Needles or drug supplies
  • Carbon monoxide
  • Flammable gases
  • Other people or animals showing symptoms

Do not enter an unsafe area without proper training and protective equipment.

If several people in the same building suddenly develop headache, dizziness, nausea, confusion, breathing problems, or loss of consciousness, leave the area and call 911. A gas leak, carbon monoxide, or another airborne hazard may be present.

Do not turn electrical switches on or off, use a lighter, or create a spark around an unknown gas or chemical vapor.

Call 911 for Emergency Symptoms

Call 911 or your local emergency number if the person:

  • Is unconscious or difficult to wake
  • Has collapsed
  • Has a seizure
  • Has trouble breathing
  • Has stopped breathing normally
  • Is severely confused or agitated
  • Has blue, gray, or unusually pale skin
  • Has severe chest pain
  • Has severe burns
  • Is choking
  • Is vomiting repeatedly and becoming less responsive
  • Has intentionally taken a poison or overdose
  • May harm themselves or another person
  • Was exposed to an unknown gas or large chemical release
  • Cannot be removed from the exposure safely
  • Has another life-threatening symptom

If the person is not breathing normally, begin CPR and use an AED as soon as one is available. Avoid direct mouth-to-mouth contact if the mouth or face is contaminated with a chemical.

Follow the dispatcher’s instructions.

Contact Poison Control Immediately

For a possible poisoning without immediate life-threatening symptoms, call Poison Control at 1-800-222-1222.

Do not decide that the exposure is harmless based only on:

  • The amount
  • The person’s current appearance
  • The product being sold without a prescription
  • The substance being “natural”
  • A lack of immediate symptoms
  • Information from an online discussion
  • A previous exposure that caused no problems

The poison specialist will consider:

  • The exact substance
  • Product strength
  • Amount
  • Person’s age and weight
  • Time of exposure
  • How the exposure occurred
  • Current symptoms
  • Medical conditions
  • Medications
  • Pregnancy
  • Whether more than one substance was involved

Poison Control recommends contacting them immediately rather than waiting for symptoms to appear. Poison Control: Get Immediate Assistance

Gather Information Before Calling

When possible, have the following available:

  • Product container
  • Medication bottle
  • Package label
  • Ingredient list
  • Pill imprint
  • Product strength
  • Estimated amount
  • Time of exposure
  • Person’s age and weight
  • Symptoms
  • Medical conditions
  • Current medications
  • Location of the exposure

If the person vomited, you may be asked about the appearance or whether pill fragments were present. Do not handle vomit with bare hands.

Do not delay the call while searching for information. Call first and gather additional details while speaking with the specialist.

If a Poison Was Swallowed

Call Poison Control immediately.

Do not:

  • Make the person vomit.
  • Give syrup of ipecac.
  • Give salt water.
  • Give activated charcoal unless specifically directed.
  • Give milk, food, water, juice, or another drink unless Poison Control instructs you.
  • Give vinegar, lemon juice, baking soda, or another substance to “neutralize” the poison.
  • Force anything into the mouth.
  • Wait for symptoms.

Making someone vomit can cause additional damage, especially when the substance is corrosive, oily, or easily inhaled into the lungs.

If material remains in the mouth, have the person spit it out when they are awake and able to do so safely. Gently wipe or rinse the mouth only as directed by Poison Control or the product’s emergency instructions.

Never give anything by mouth to someone who is unconscious, having a seizure, confused, vomiting continuously, or unable to swallow.

Medication Poisoning and Double Doses

Medication poisoning may involve:

  • Taking too much
  • Taking a second dose accidentally
  • Using the wrong medication
  • Combining interacting medicines
  • Taking someone else’s prescription
  • A child accessing medication
  • Mixing medication with alcohol or drugs
  • Using several products containing the same active ingredient
  • Taking a delayed-release product incorrectly

Call Poison Control even if the person feels well.

Provide:

  • Medication name
  • Strength
  • Number of pills or amount of liquid
  • Time taken
  • Person’s age and weight
  • Other medications, alcohol, or substances involved
  • Whether the dose was intentional

Do not make the person vomit. Do not give another medication to reverse the effects unless a qualified professional directs you.

Do not automatically repeat a medication dose after vomiting. Some or all of the medication may already have been absorbed.

Acetaminophen Exposure

Acetaminophen is found in many pain, fever, cold, flu, and sleep products. Taking several products can cause an accidental overdose.

A person with an acetaminophen overdose may initially feel normal or have only mild nausea. Serious liver damage can develop later.

Call Poison Control immediately if someone may have taken too much. Do not wait for abdominal pain, vomiting, yellow skin, or other symptoms.

Bring every medication container involved.

Opioid Overdose

Possible signs include:

  • Inability to wake
  • Slow, shallow, or stopped breathing
  • Gasping, snoring, or gurgling sounds
  • Pinpoint pupils
  • Blue, gray, or pale lips or skin
  • A limp body

Call 911 immediately.

Give naloxone when it is available and you know how to use it. Naloxone can temporarily reverse the breathing effects of an opioid overdose but may wear off before the opioid does.

After giving naloxone:

  • Follow the product instructions.
  • Begin CPR or rescue breathing according to your training and dispatcher instructions.
  • Give another dose when directed.
  • Stay with the person.
  • Do not allow them to refuse emergency evaluation simply because they woke up.

Do not put the person in a cold shower, slap them, force them to walk, or give them coffee.

If a Chemical Gets Into the Eyes

Begin rinsing immediately. Do not delay rinsing while calling for help.

For most eye exposures:

  1. Move away from the source.
  2. Remove contact lenses when they can be removed easily.
  3. Hold the eyelids open.
  4. Rinse with clean, lukewarm or room-temperature water.
  5. Allow water to flow gently across the eye.
  6. Continue rinsing for at least 15 to 20 minutes or as directed.
  7. Call Poison Control for additional instructions.

A shower, sink, eyewash station, or clean container may be used. Keep the water pressure gentle.

If only one eye is affected, position the head so contaminated water drains away from the unaffected eye.

Do not:

  • Rub the eye.
  • Use eye drops.
  • Attempt to neutralize the chemical.
  • Put ointment in the eye.
  • Replace contaminated contact lenses.
  • Delay rinsing because the person wants to find the product label.

Seek immediate medical care for severe pain, vision changes, persistent redness, inability to open the eye, exposure to a strong chemical, or symptoms that continue after rinsing.

Poison Control advises immediate irrigation because delaying eye rinsing can result in serious injury. Poison Control: First Aid for Poisonings

If a Chemical Gets Onto the Skin

Protect yourself before touching contaminated skin or clothing. Wear disposable or chemical-resistant gloves when available.

For a liquid exposure:

  1. Move away from the source.
  2. Blot away visible liquid without spreading it.
  3. Remove contaminated clothing, shoes, jewelry, and accessories.
  4. Rinse the skin with large amounts of lukewarm water.
  5. Use mild soap when appropriate.
  6. Avoid aggressive scrubbing.
  7. Call Poison Control for specific instructions.

For a dry chemical:

  1. Protect yourself.
  2. Carefully brush away the dry material.
  3. Avoid creating airborne dust.
  4. Remove contaminated clothing.
  5. Rinse as directed by Poison Control or the product’s emergency instructions.

Some chemicals react with water or require specialized handling. If you know the product, follow the emergency information on the label while contacting Poison Control.

Do not apply:

  • Ointment
  • Cream
  • Grease
  • Household remedies
  • Another chemical intended to neutralize the first

Remove Contaminated Clothing Safely

Removing clothing can eliminate much of the chemical from the body.

When possible:

  • Cut clothing off instead of pulling it over the head.
  • Avoid touching contaminated areas.
  • Remove shoes, socks, jewelry, and accessories.
  • Place contaminated items away from other people.
  • Follow emergency instructions for bagging or disposal.
  • Put on clean clothing after washing.

If clothing must be pulled over the head, close the eyes and mouth and avoid breathing in contamination.

The CDC advises removing contaminated clothing and washing the skin as quickly as possible after a chemical emergency. CDC: About Getting Clean

Do not put contaminated clothing into an ordinary laundry load until Poison Control, emergency responders, or the product instructions confirm that it is safe.

If Poison Was Inhaled

Do not enter a contaminated space to rescue someone unless it is safe and you have appropriate training and equipment.

Call 911 for:

  • Difficulty breathing
  • Chest tightness
  • Wheezing
  • Confusion
  • Collapse
  • Severe coughing
  • Exposure in an enclosed space
  • Several affected people
  • Unknown gas or chemical vapor
  • Smoke from a fire
  • Intentional chemical release

When it is safe:

  1. Move to fresh air.
  2. Go upwind and away from the source during an outdoor release.
  3. Open doors or windows only if doing so does not increase your exposure.
  4. Loosen tight clothing.
  5. Monitor breathing.
  6. Call Poison Control for additional instructions.

Do not light a flame or create a spark.

Some inhaled chemicals can cause delayed lung injury. Seek medical advice even when symptoms improve after leaving the area.

Carbon Monoxide Exposure

Carbon monoxide is a colorless, odorless gas produced by combustion. It can come from:

  • Furnaces
  • Generators
  • Vehicles
  • Fireplaces
  • Grills
  • Gas appliances
  • Space heaters
  • Fires

Possible symptoms include:

  • Headache
  • Dizziness
  • Nausea
  • Weakness
  • Confusion
  • Chest pain
  • Shortness of breath
  • Loss of consciousness

Symptoms affecting several people in the same location are especially concerning.

Leave the building immediately and call 911 from outside. Do not reenter to retrieve belongings or pets.

Do not attempt to locate the source yourself. Firefighters or utility professionals can check the building safely.

Household Cleaner Exposures

Never mix household cleaning products.

Especially dangerous combinations include:

  • Bleach and ammonia
  • Bleach and acids
  • Bleach and vinegar
  • Bleach and toilet-bowl cleaner
  • Different drain cleaners
  • Cleaning chemicals and alcohol

These combinations can release toxic gases or cause violent chemical reactions.

If cleaners are accidentally mixed:

  1. Leave the area immediately.
  2. Move to fresh air.
  3. Do not attempt to clean the mixture.
  4. Call 911 for breathing problems or significant exposure.
  5. Contact Poison Control.

Do not turn on a fan or reenter to open windows if doing so requires entering a dangerous concentration of fumes.

Pesticide Exposure

Pesticides may be swallowed, inhaled, absorbed through the skin, or splashed into the eyes.

Possible symptoms include:

  • Nausea
  • Vomiting
  • Sweating
  • Drooling
  • Headache
  • Dizziness
  • Muscle twitching
  • Weakness
  • Confusion
  • Breathing problems
  • Seizures

Move away from the source, remove contaminated clothing, rinse exposed skin, and call Poison Control.

Call 911 for severe symptoms.

Keep the pesticide label or product name available because treatment depends on the exact chemical.

Button Batteries and Magnets

A swallowed button battery is an emergency. It can become lodged in the esophagus and cause severe tissue damage quickly.

Seek immediate medical care and contact Poison Control or the National Battery Ingestion Hotline at 1-800-498-8666.

Do not:

  • Wait for symptoms.
  • Make the person vomit.
  • Give food or drink unless specifically directed.
  • Assume the battery will pass safely.

Swallowed high-powered magnets can also trap or damage intestinal tissue. Seek immediate medical evaluation.

Plants, Mushrooms, and Berries

Do not assume a plant, mushroom, berry, or herbal product is safe because it is natural.

If someone eats an unknown plant or mushroom:

  • Remove remaining pieces from the mouth.
  • Do not make the person vomit.
  • Save a sample or take clear photographs when safe.
  • Call Poison Control.
  • Note where it was found and how much may have been eaten.

Do not rely on a phone application or internet image alone to identify whether something is safe.

Bites and Stings

Certain bites and stings may involve venom and require Poison Control or emergency guidance.

Call 911 for:

  • Difficulty breathing
  • Facial or throat swelling
  • Severe weakness
  • Fainting
  • A seizure
  • Confusion
  • Rapidly worsening symptoms
  • A known dangerous snakebite
  • A severe allergic reaction

Do not:

  • Cut the wound.
  • Attempt to suck out venom.
  • Apply ice to a snakebite.
  • Apply an electric shock.
  • Use a tourniquet unless emergency professionals specifically direct it.
  • Attempt to capture a dangerous animal.

Keep the person still and note the animal’s appearance from a safe distance.

Intentional Poisoning or Overdose

Call 911 for an intentional ingestion, overdose, or chemical exposure.

Do not leave the person alone.

Remove additional substances only when it can be done safely. Do not argue, threaten, shame, or promise secrecy.

Tell responders:

  • What may have been taken
  • How much
  • When
  • Whether alcohol or other drugs were involved
  • Whether the person has access to more
  • Any messages, notes, or statements indicating intent

If there is an emotional crisis without an immediate medical emergency, call or text 988 in the United States. When poisoning has already occurred or immediate danger exists, call 911 first.

Children and Poisoning

Children may swallow or touch a product without telling anyone.

Possible clues include:

  • An open container
  • Pills on the floor
  • Stains around the mouth
  • An unusual odor
  • Sudden vomiting
  • Unexplained sleepiness
  • Burns around the mouth
  • Drooling
  • Difficulty breathing
  • Sudden unusual behavior

Call Poison Control immediately. Do not wait for symptoms or attempt to calculate risk on your own.

Provide the child’s age, weight, product, strength, estimated amount, and time of exposure.

Keep medicines, cleaners, nicotine products, cannabis products, alcohol, batteries, and chemicals locked away and stored in their original containers.

Older Adults and Medication Poisoning

Older adults may be at increased risk because of:

  • Multiple prescriptions
  • Similar-looking pills
  • Vision problems
  • Memory changes
  • Kidney or liver disease
  • Medication interactions
  • Difficulty reading labels
  • Changes in dosage
  • Taking medication from more than one prescriber

Call Poison Control for a possible medication error, even if no symptoms are present.

Bring an accurate medication list and all relevant containers to medical care.

Pets and Poisoning

Human Poison Control primarily advises about human exposures. If a pet may have been poisoned, contact a veterinarian or an animal poison-control service.

Do not give a pet a human medication or make the animal vomit unless a veterinary professional directs you.

Keep people away from the same source while arranging veterinary assistance.

After the Immediate Exposure

Follow every Poison Control or medical instruction carefully.

You may be told to:

  • Monitor at home
  • Watch for specific symptoms
  • Repeat rinsing
  • Go to urgent care
  • Go to an emergency department
  • Call 911
  • Obtain laboratory testing
  • Return a call at a specific time

Write down:

  • Who you spoke with
  • The time
  • Instructions
  • Symptoms to monitor
  • Follow-up requirements

Do not stop monitoring simply because the person feels better.
