Household Health · Chapter 8
Poisoning prevention and response
More than two million poisoning exposures are reported to U.S. poison control centers every year. The majority happen at home. The majority involve products that every household has: medicines, cleaning supplies, personal care products, and pesticides. Prevention is storage discipline. Response is one phone number.

Response
Poison Help versus 911
Both numbers are correct. Which one to call depends on the person's condition, not on what they were exposed to.
Call 911 when
The person is unconscious or unresponsive
The person is not breathing or is having difficulty breathing
The person is having a seizure
You believe the situation is immediately life-threatening
Call Poison Help when
A child got into medicine or a household product
Someone swallowed something they should not have
Someone got a chemical on their skin or in their eyes
Someone inhaled something harmful
You are not sure whether what happened is dangerous
If you are unsure which to call, call Poison Help. The poison experts will assess the situation and tell you whether the person needs emergency care. If they do, the experts will tell you to call 911 and may stay on the line or coordinate directly with the responding team.
What to tell them
When you call Poison Help, have this information ready if you can:
The person's age and approximate weight
What they were exposed to (have the container or product in hand if possible)
How much, if you can estimate
When it happened
How the person seems right now (alert, drowsy, vomiting, in pain, breathing normally)
Any known medical conditions or other medicines the person takes
Do not delay calling because you do not have all of this information. Call with what you know. The poison expert will ask the questions they need answered and guide you through the next steps.
What happens when you call
Some people hesitate to call Poison Help because they are embarrassed, because they think the situation is not serious enough, or because they do not know what to expect. Here is what actually happens.
A trained specialist answers. They ask you calm, specific questions about who was exposed, what they were exposed to, how much, and when. They are not judging you. They handle over two million calls a year. They have heard every scenario. Their entire job is to help you figure out what to do next.
Based on your answers, they will do one of three things: tell you the exposure is not dangerous and what to watch for; give you specific instructions to manage the situation at home; or tell you to go to the emergency room (and may call ahead to the ER to prepare the team). For some calls, they will follow up later to check on the person.
The call is free. There is no bill. There is no report to anyone. You can call for any poisoning question, even if you are not sure whether it is a real exposure. "My toddler had the bottle open but I do not know if she swallowed any" is a perfectly valid reason to call. So is "I accidentally took two of my blood pressure pills instead of one" and "my dog ate a box of rat poison and I am worried about the children who play in the yard." Call for the situation you are not sure about. That is exactly what the line is for.
Critical
What not to do when a poisoning happens
HRSA Poison Help warns specifically against improvised remedies. The instinct to "do something" before calling is strong, but the wrong action can make the situation worse. Some substances cause more damage coming back up than they did going down. Some home remedies interact dangerously with the substance that was swallowed. Some actions delay the treatment the person actually needs.
Do not do any of these unless specifically instructed by Poison Help or a medical professional
Do not induce vomiting. Caustic substances (drain cleaners, oven cleaners, strong acids) burn going down and burn again coming back up, causing additional injury to the esophagus and mouth. Petroleum products can be aspirated into the lungs during vomiting, causing chemical pneumonia.
Do not give activated charcoal unless poison experts determine it is appropriate. Activated charcoal is a medical intervention with specific indications and contraindications. It does not work on all substances, it can cause vomiting or aspiration, and it is not safe in all situations.
Do not give milk, water, salt water, or any other home remedy to counteract the poison. These remedies are based on folk medicine, not evidence, and some can cause additional harm.
Do not wait to see if symptoms develop. Some poisons cause delayed symptoms. By the time symptoms appear, the window for effective treatment may have narrowed. Call Poison Help as soon as you know or suspect an exposure.
The correct action is almost always: call Poison Help, describe what happened, and follow their specific instructions. They will tell you whether to go to the ER, what to do while you wait, or whether the exposure is not dangerous and can be managed at home. They make this determination based on the specific substance, the amount, the person's age and weight, and the time elapsed. You cannot make this determination from a web page, and neither can this one.

The leading source
Medicines are the most common poison source
Medicines are the leading source of poisoning in both children and adults. In children, the most common exposures involve over-the-counter pain relievers, vitamins and supplements, cough and cold products, and prescription medications left within reach. In adults, common poisoning scenarios involve medication errors (taking the wrong dose, double-dosing, confusing two similar-looking pills), interactions between medications, and accidental ingestion by older adults with cognitive changes.
The medicine safety practices in Chapter 3 are the primary prevention layer here: storing medicines correctly, controlling access, following label directions, and maintaining the medication list. This chapter adds the prevention practices specific to poisoning risk and the response protocol when prevention fails.
Medicine-specific prevention
Child-resistant does not mean child-proof. Child-resistant packaging slows a child down. It does not stop them. A determined toddler can open a child-resistant cap given enough time. The cap buys you time to notice. It does not replace locked or out-of-reach storage.
Re-lock after every use. The most common access scenario is a medicine left out after use: on a counter, on a nightstand, in a purse on the floor, in a bag left open. Return medicines to locked or out-of-reach storage immediately after every use, every time.
Visitor and guest medicines. Grandparents' pill organizers, guests' prescription bottles in open luggage, purses with loose pills: visiting medicines are among the most common sources of pediatric poisoning because they are not stored in the household's usual controlled location. Ask guests to keep medicines zipped, latched, or out of reach.
Vitamins and supplements. Gummy vitamins look and taste like candy. Iron supplements are particularly dangerous for children in even small amounts. Treat vitamins and supplements with the same storage discipline as prescription medications.
Medication errors in adults. Using a pill organizer, maintaining the medication list from Chapter 3, and confirming doses at each administration all reduce the risk of taking the wrong medicine or the wrong dose. For older adults managing multiple medications, a medication review with a pharmacist can identify interaction risks and simplify the regimen where possible.
Age-specific poisoning risks
The most common poisoning scenarios are different at different ages, which means the prevention focus shifts as the household changes.
| Age group | Primary risks and prevention focus |
|---|---|
| Under 6 | Exploratory ingestion: medicines, cleaning products, plants, personal care products, small batteries. Prevention centers on physical barriers (locks, height, supervision) because reasoning with a two-year-old about chemical hazards does not work. |
| 6 to 12 | Accidental medication errors, product misuse, and curiosity about chemicals. Prevention shifts from pure physical barriers to a combination of barriers and education: teaching children not to take any medicine without an adult, not to eat or drink anything they did not receive from a trusted adult, and to tell an adult immediately if they swallow or touch something they should not have. |
| Teenagers | Intentional misuse of over-the-counter medicines (cough suppressants, pain relievers, sleep aids), accidental alcohol poisoning, and inhalant abuse (aerosol products, solvents, gases). Prevention includes honest conversation, awareness of what is accessible, and knowing that Poison Help handles these calls without judgment. |
| Adults | Medication errors (wrong dose, double dose, interactions), workplace chemical exposure, carbon monoxide, food contamination. Prevention centers on the medication list, label-reading discipline, and chemical storage practices. |
| Older adults | Medication errors amplified by polypharmacy (multiple medications from multiple providers), vision changes that make labels hard to read, cognitive changes that affect dosing accuracy, and confusion between similar-looking pills. Prevention centers on the medication list, pill organizers, pharmacist reviews, and caregiver oversight when cognition declines. |
Household chemicals
Chemical storage and the mixing rule
HRSA Poison Help recommends four rules for household chemicals. These rules are simple, they are evidence-based, and they prevent the most common chemical poisoning scenarios in homes.
1. Keep hazardous products locked or out of reach
Cleaning supplies, laundry pods, dishwasher pods, pesticides, automotive fluids, paint thinners, and any product with a warning label. Under-sink cabinets should have child locks if children or cognitively impaired adults are in the home. Garage and workshop chemicals should be on high shelves or in locked cabinets.
2. Keep products in their original labeled containers
The label is how you know what is in the container, what the hazards are, and what to tell Poison Help if someone is exposed. Transferring a cleaning product to an unmarked spray bottle, a chemical to a jar, or a pesticide to an old milk jug removes the one piece of safety information that makes correct response possible.
3. Never store chemicals in food or drink containers
Antifreeze in a sports drink bottle. Drain cleaner in a juice container. Pesticide in a soda bottle. These are not hypothetical scenarios. They are among the most preventable and most dangerous poisoning situations reported to poison control centers. A child or an adult who is thirsty will drink from a familiar container without checking what is inside.
4. Never mix chemical products
Mixing bleach with ammonia produces chloramine gas. Mixing bleach with acids (including some toilet bowl cleaners and rust removers) produces chlorine gas. Mixing hydrogen peroxide with vinegar produces peracetic acid. These reactions can cause respiratory distress, chemical burns, and in enclosed spaces, death. Use one product at a time, rinse surfaces between products, and never combine cleaning agents to make them "stronger."
Laundry and dishwasher pods
Single-use laundry and dishwasher pods are a significant poisoning risk for young children. The pods are brightly colored, soft, and small enough to fit in a child's mouth. The concentrated detergent inside can cause chemical burns to the eyes, mouth, and throat, and can cause vomiting and breathing difficulty if swallowed. Store pods in their original container with the lid closed, in a locked cabinet or on a high shelf. Do not leave pods loose in a basket, on a counter, or anywhere a child can reach them.

Inhalation
Carbon monoxide is a poison
Carbon monoxide poisoning is covered in Chapter 7 under CO alarms, but it belongs here too because CO is a poison, not just a household safety issue. CO replaces oxygen in the blood. Early symptoms (headache, dizziness, weakness, nausea, confusion) mimic the flu and are easily dismissed, especially when multiple household members develop them simultaneously.
The prevention layer is the CO alarm system described in Chapter 7. The response layer is immediate evacuation and 911. But there is a recognition layer between prevention and response that matters: knowing the symptoms and knowing what makes CO poisoning different from a stomach bug.
The pattern that should trigger suspicion
Multiple people in the same building developing headache, nausea, or dizziness at the same time. Symptoms that improve when the person leaves the building and return when they go back inside. Symptoms that appear during cold weather when the furnace is running, when a generator is operating, or after a fuel-burning appliance has been used indoors.
If this pattern appears and the CO alarm has not sounded, get everyone outside to fresh air and call 911 anyway. The alarm may have a dead battery, may be past its replacement date, or may not be installed in the right location. Trust the symptoms.
Other routes
Skin and eye exposure, bites, and stings
Poisoning is not limited to swallowing. Chemical exposure to skin and eyes, inhaling fumes, and envenomation from bites and stings are all poisoning events that Poison Help handles.
Chemical on skin
Remove contaminated clothing. Rinse the affected skin with large amounts of running water for at least 15 to 20 minutes. Call Poison Help while rinsing (or immediately after) for guidance specific to the substance. Do not apply creams, ointments, or home remedies to a chemical burn unless directed by Poison Help or a medical professional.
Chemical in eyes
Rinse the eye with clean, lukewarm running water for at least 15 to 20 minutes. Hold the eyelid open and let the water run across the eye from the inner corner outward. Call Poison Help for guidance on whether additional medical evaluation is needed. Some chemicals cause delayed damage that is not immediately painful, so professional guidance matters even when the initial discomfort fades.
Bites and stings
Poison Help also handles questions about snake bites, spider bites, scorpion stings, and insect stings. If someone has a known severe allergy (anaphylaxis risk), follow their emergency plan (typically an epinephrine auto-injector and 911). For bites and stings where the severity is unknown, call Poison Help. They can help you assess whether the bite requires medical evaluation and what to do while waiting.
The routine
Making prevention a household habit
Prevention is not a one-time project. It is a set of habits that run continuously. The twice-a-year safety walk from Chapter 7 catches the big items. The daily habits catch the rest.
Daily habits
Return medicines to locked or out-of-reach storage after every use. Every time. Not "in a minute." Now.
Return cleaning products to their storage location after use. Do not leave spray bottles on counters, bleach on the bathroom floor, or laundry pods on top of the washing machine.
Check that cabinet locks are engaging after you close them. Locks that do not latch because the mechanism is loose or the cabinet is warped provide no protection.
Seasonal and event-triggered checks
When a baby becomes mobile: Re-evaluate every reachable surface and cabinet. What was safe at crawling height becomes unsafe at walking height and unsafe again at climbing height.
Before guests arrive: Ask guests to keep medicines in a closed bag or out of reach. Visitor medicines in open luggage are a documented pediatric poisoning risk.
When an older adult's cognition changes: Re-evaluate access to cleaning products, automotive chemicals, and medications. Confusion can lead to drinking cleaning products that look like beverages or taking medicines incorrectly.
Spring and fall (safety walk): Check all chemical storage locations. Verify child locks are functional. Confirm the Poison Help number is posted. Check that the CO alarm batteries and units are current.
The pattern in every case is the same: reduce access, maintain labels, do not mix, and know the number. Prevention that runs as a habit is dramatically more effective than prevention that depends on someone remembering to be careful.
