Acetaminophen is a very safe drug to take according to label instructions. In overdose, too much acetaminophen can damage the liver. In fact, acetaminophen overdose is an important cause of liver failure and liver transplants in the US.
Acetaminophen is a very safe medicine when used in recommended doses to treat pain and fever. But too much acetaminophen can cause liver damage and even death. This has happened when parents didn't understand the concentration or measurements. New formulations of acetaminophen for children make it easier to give the correct dose.
Acetaminophen is a safe and effective pain reliever when taken according to label instructions. But in overdose, it is a leading cause of liver damage and death.
There is no evidence that cough and cold medicines are safe or effective for young children. There IS evidence that children have been harmed by overdoses of these products. Problems include seizures, coma, and death.
Activated charcoal keeps swallowed drugs and poisons from being absorbed from the gut into the bloodstream. It's a highly effective treatment for many poisons.
Hangovers are unpleasant symptoms that occur after consumption of alcohol. Even though many products are marketed as hangover treatments, there is no cure for this condition. The best way to prevent a hangover is to avoid drinking excessive amounts of alcohol.
Alcohol can be a dangerous poison for children. Alcohol depresses the central nervous system and causes low blood glucose (sugar). Children who drink alcohol can have seizures and coma; they could even die. This is true of beverage alcohol (beer, wine, liquor) and alcohol found in mouthwash and other personal care products.
Rubbing alcohol looks like water. Even small amounts are poisonous to children. It is also poisonous to adults, who sometimes substitute rubbing alcohol for drinking alcohol. Rubbing alcohol can also be toxic when inhaled. It should be used in a well-ventilated area. In addition, because it is flammable, it should always be kept away from open flame.
Alcohol vapors can be produced by heating up alcohol or pouring it over dry ice. Alcohol can be absorbed into your bloodstream by inhaling alcohol vapors. People who inhale alcohol vapors get drunk very quickly, because the alcohol goes straight to the brain. Also, heated alcohol vapor can injure the lungs.
Ethanol, found in alcoholic beverages, is safe for most adults in moderation. Excessive ethanol intake and consumption of other types of alcohol can be dangerous.
Lots of alcohol plus lots of caffeine equals danger, with possible results ranging from sexual assault to automobile crashes to alcohol-induced coma or even death.
Most fragrance products contain alcohol; some contain up to 95%. Alcohol can cause serious effects in children. Fragrance products can also cause skin irritation, which will usually go away if you stop using the product.
Over the river and through the woods, to grandmother's house - or maybe on a cruise - or perhaps to a hotel in a new city or a foreign country? Wherever your destination for the holidays, by automobile, plane, ship or sleigh, a little planning will help keep holiday travel safe and enjoyable.
A lick of hand sanitizer won't hurt a child or anyone else. Drinking it can cause alcohol poisoning, which can cause low blood sugar, coma, and seizures – though this is not common.
It is dangerous to swallow antifreeze, even small amounts. For several hours after swallowing, everything seems fine. But don't be fooled - the body is busy breaking down the antifreeze (ethylene glycol) into a number of substances that affect blood chemistry, the nervous system, and kidneys. If the victim survives, there may be permanent damage to the kidneys and brain.
There are special poisoning concerns during the winter: family travel, family gatherings, carbon monoxide poisoning, and winter chemicals for the car. Follow Poison Control's prevention tips to keep your family safe this winter.
Ibuprofen, naproxen, and aspirin are non-steroidal anti-inflammatory drugs (NSAIDs). They are used to treat pain, fever, and inflammation. They are also found in combination products such as cough and cold medicines. An overdose of these medications may cause stomach upset, abdominal pain, and vomiting, kidney damage, ulcers, bleeding, seizures, and coma.
Aspirin is an over-the-counter medication used as an anti-inflammatory agent and for pain or fever relief. Low dose aspirin is used to prevent heart attacks and strokes in people with existing heart disease, and sometimes in pregnancy to prevent preeclampsia. Normal side effects include stomach upset and indigestion. Aspirin overdose can be life-threatening.
Children will swallow anything they can reach. Most of the time, these objects pass through the gastrointestinal tract with no trouble; the object turns up in the child's stool. Sometimes, surgery is needed to remove the object(s). In one recent study, coins made up 80 percent of swallowed foreign objects that had to be removed by surgery.
Swallowed batteries burn through a child's esophagus in just 2 hours, leading to surgery, months with feeding and breathing tubes, and even death. About the size of a nickel, 20 mm, 3-volt lithium coin cells are the most hazardous as they are big enough to get stuck and burn faster. Secure battery compartments and keep loose batteries away from children.
More and more children are being injured, or even dying, from swallowing button or disk batteries. This tragedy can be prevented. Batteries stuck in the esophagus must be removed as quickly as possible as severe damage can occur in just 2 hours. Batteries in the nose or ear also must be removed immediately to avoid permanent damage.
A recent study of battery injuries found that 29.8% of button battery ingestions involved batteries that were discarded or sitting out. Taping button batteries before disposal can decrease or stop button batteries from causing injury and will not affect the ability of the battery to be recycled.
Over the river and through the woods, to grandmother's house - or maybe on a cruise - or perhaps to a hotel in a new city or a foreign country? Wherever your destination for the holidays, by automobile, plane, ship or sleigh, a little planning will help keep holiday travel safe and enjoyable.
Buprenorphine is prescribed for adults with opioid dependence or chronic pain. Most buprenorphine poisoning in children occurs due to improper storage of the medication. Symptoms of buprenorphine poisoning in children are drowsiness, vomiting, slow breathing, increased heart rate, and agitation. Coma and death have also been reported.
Symptoms of caffeine overdose can be mild (shaky hands, stomach upset) to severe (high blood pressure, seizures, coma). Caffeine is found in traditional sources (coffee, tea, chocolate, soda) and many new sources (energy drinks, foods with added caffeine). Children are taking in more and more caffeine, but we don't know how much is safe for children.
"ADHD" stands for "attention deficit hyperactivity disorder". Symptoms include hyperactivity, impulsiveness, and inability to pay attention, manage frustration, stay organized, or focus on tasks. Treatment is based on behavior therapy and/or drug therapy. ADHD drugs can cause side effects; a deliberate overdose of any amount requires immediate medical care.
Many weight loss supplements contain ingredients that are contaminated, ineffective, dangerous, or actually illegal. Some people become ill after taking these products. Some have interactions with medicines. It can be hard to get your money back. Worst of all, these products often don't help.
Pre-workout supplements can contain caffeine and other ingredients which can be poisonous when taken in large amounts. Dry scooping, or consumption of undiluted pre-workout powder, can be life-threatening.
Lots of alcohol plus lots of caffeine equals danger, with possible results ranging from sexual assault to automobile crashes to alcohol-induced coma or even death.
The line between enough caffeine and too much varies from person to person. People who overdo it can experience unpleasant side effects until the caffeine wears off in a few hours. People who take too many caffeine pills to stay awake can have seizures. There have even been some deaths from caffeine overdoses.
So many poison prevention stories are about children, but when it comes to home remodeling, adults are at risk, too. Children, adults, and pets can become sick if home renovations are not carried out carefully.
There is a lot of information about avoiding drugs, alcohol, and tobacco while pregnant. There are some other poisons to be aware of if you're pregnant, including herbal medications, supplements, lead, and carbon monoxide.
Shortly after a hurricane in Texas, 75% of children treated for carbon monoxide poisoning had been playing video games powered by portable generators.
It is possible for heavy smokers to develop carbon monoxide poisoning. This can be severe enough to require treatment in an emergency room.
It's not an intriguing or novel hazard, just the persistent, invisible killer: carbon monoxide. Seriously, you still don't have a carbon monoxide alarm in every sleeping area of your home? Get one! And keep fuel-burning appliances in good repair; don't use grills or gasoline-powered tools indoors, and don't run your car in an attached garage or place a generator close to your home.
There are special poisoning concerns during the winter: family travel, family gatherings, carbon monoxide poisoning, and winter chemicals for the car. Follow Poison Control's prevention tips to keep your family safe this winter.
Over the river and through the woods, to grandmother's house - or maybe on a cruise - or perhaps to a hotel in a new city or a foreign country? Wherever your destination for the holidays, by automobile, plane, ship or sleigh, a little planning will help keep holiday travel safe and enjoyable.
Chelation therapy is a treatment for heavy metal poisoning: iron, mercury, arsenic, and lead. Some people give chelation "therapy" for other conditions such as cardiovascular disease, autism, and Alzheimer's. This exposes patients to risks without benefit. A large study of chelation therapy for cardiovascular disease leads some researchers to suggest further study.
More and more household cleaning products are found in spray bottles. More and more children are being poisoned by those products. Cleaning products in spray bottles are now the leading source of cleaning products that poison children. Most injuries are to the eyes and head. It's important to wash the skin and eyes right away with lots of running water.
Povidone is found in both medical and household items and can cause mild symptoms with large ingestions. Povidone iodine is a common antiseptic used to disinfect the skin, eyes, and vagina. When used correctly, povidone iodine might cause mild side effects, but it can cause major problems when used incorrectly.
Melioidosis is a serious infection caused by the bacteria Burkholderia pseudomallei. Humans can be exposed to the bacteria through contact with contaminated water or soil in tropical countries. In 2021, an outbreak of melioidosis occurred in the United States due to contaminated aromatherapy spray.
Ammonia is a chemical that can be naturally or artificially produced. The toxicity of ammonia depends on its concentration. Most household products containing ammonia are safe when used as directed, but some have the potential to cause burns. Industrial products are typically more concentrated and more likely to cause burns.
Laundry fragrance boosters are scented, dissolvable beads intended to extend the smell of fresh laundry for weeks beyond the wash date. Currently available products are relatively safe even when swallowed by children.
Laundry pods are a huge new category of cleaning product. For unknown reasons, this type of laundry liquid has caused dangerous injury to children and at least one death. Effects of biting into a laundry pod include coughing, choking, trouble breathing, coma, and possibly death. The detergent also can irritate the skin and burn the eyes.
Liquid drain cleaners contain potentially poisonous acidic or basic compounds, enzymes, and bacteria that are effective in clearing clogged drains. Since many drain cleaners contain highly concentrated corrosive chemicals, they must be used with caution. Consumption of non-enzymatic drain cleaners can result in serious burns, permanent tissue damage, and even death.
Automatic dishwashing detergents (ADDs) are available as powders, liquids, tablets, and pods. Exposure to ADDs is common and often results in irritation. Severe effects, such as burns and tissue damage, can also occur depending on the type of ADD, the amount, and the duration of exposure.
Household bleach is used for cleaning and disinfecting and can also be used in “bleach baths” as a medical treatment for atopic dermatitis. Swallowing, inhaling, or injecting bleach can cause serious medical problems.
Caustic products cause burns on contact with skin, eyes, and the gastrointestinal tract. More than other household products, caustic substances do their damage instantly. Injury cannot be reversed, only treated.
A variety of cleaning products are available to maintain wood floors. Wood floor cleaners are usually based on hydrocarbons, detergents, or glycol ether solvents. Each type carries its own precautions and potential adverse effects. Floor cleaners can also contain alcohol, weak acids, or alkaline chemicals to strengthen their cleaning properties.
The same qualities that make oven and grill cleaners desirable and effective–dissolving tough, baked-on food and grease–also make them poisonous. Oven and grill cleaners often have a high pH, making them alkaline corrosives. Upon contact, via any route, they can cause tissue damage, burns and, at the very least, irritation.
A clean home provides a healthy environment for your family, but household cleaning products can contain hazardous chemicals. Acid, alkali, bleach, polish, detergent? It’s important to be aware of the most common cleaner ingredients, what they are intended (and not intended) to do, and how to use them safely.
During the past decade, the use of cleaning wipes has increased substantially. Cleaning wipes are available for a variety of surfaces. Since they are meant to be used with bare hands, they are mostly water and are not commonly associated with toxicity.
Windex® products are designed for cleaning glass, outdoor furniture, and hard surfaces. There are many different formulations of Windex®. The ingredients vary between products, but they typically contain surfactants, solvents, and dyes. These chemicals are irritating when swallowed and can cause unwanted signs and symptoms including vomiting and abdominal pain.
Children get into all kinds of home laundry products. Some can cause irritation, from mild to painful: stain removers, pre-treatment agents, liquid and powder detergents, and fabric softeners. A few can cause burns or even death, such as rust remover and laundry pods. Bleach generally causes mild effects except for newer, concentrated bleach products.
Tea tree oil has been used as a "natural" remedy for a long time, especially for skin afflictions. There is some scientific evidence that tea tree oil can be effective for certain skin conditions. It is poisonous if swallowed and so should not be used in or around the mouth at all.
We use sunscreens to protect our skin from the sun's harmful rays. In some cases though, the use of sunscreen can result in allergic reactions or photoallergic dermatitis. Fortunately, in most cases, the rash is self-limiting and can be prevented in the future by avoiding use of certain sunscreen products.
Povidone is found in both medical and household items and can cause mild symptoms with large ingestions. Povidone iodine is a common antiseptic used to disinfect the skin, eyes, and vagina. When used correctly, povidone iodine might cause mild side effects, but it can cause major problems when used incorrectly.
Even when hair dyes are used correctly, they can cause toxicity. Skin damage and allergic reactions are well documented. Eye exposure can cause a range of toxicities from mild irritation to loss of vision. Accidental swallowing can cause irritation or injury to the mouth and stomach as well as life-threatening allergic reactions.
Boric acid has antibacterial and antifungal properties, and boric acid suppositories are used by some women to treat vaginal yeast infections. The suppositories are meant to be inserted directly into the vagina, and should not be swallowed. Consumption of large amounts of boric acid may result in gastrointestinal distress, kidney problems, or death.
Chlorhexidine is an antibacterial agent that is commonly used in dental and surgical settings. Lower concentration products sold over the counter do not typically cause serious problems, but people can have adverse effects and allergic reactions even with normal use.
Chlorine dioxide and sodium chlorite are highly reactive disinfectants used to treat public water systems. They are also low-concentration ingredients in some mouthwash products. A sip is unlikely to cause anything beyond mild irritation, nausea, and short-term vomiting. Large amounts can oxidize red blood cells, making them incapable of carrying oxygen.
Deodorants work by controlling odor, while antiperspirants reduce the amount of sweat released from the body. Although some people question whether these products cause cancer or other diseases, deodorants and antiperspirants are considered to be safe when used as directed.
Genital desensitizers contain local anesthetics and are designed to numb the external genitalia to enhance sexual activities. When used in excess or too frequently, genital desensitizers can cause severe toxicity. Antidotes and medical treatments are available in hospital settings, but delays in seeking medical care can result in more severe symptoms or even death.
The bottom line for parents of infants and young children: products to prevent and treat diaper rash usually will not harm a child who swallows a small amount. The exception is talcum powder, which can be fatal if inhaled.
Styptic pencils contain aluminum compounds and are used to stop bleeding. The most common use for styptic pencils is to treat small cuts caused by shaving. When applied to the skin, they harden or coagulate the surface of a wound. However, they are not meant to be consumed and may cause stomach upset or nausea if swallowed.
Soapmaking is a popular home activity, but potentially hazardous chemicals are often involved. Use of pre-made soap bases, or “melt and pour” products, is a safer way to make homemade soap.
Toothpaste usually contains fluoride. Swallowing it can cause stomach upset. Although fluoride can lead to more serious toxicity in very large amounts, it is unlikely to occur from small, unintentional ingestions of over-the-counter, fluoride-containing toothpaste.
Shampoos contain ingredients ranging from detergents to conditioners to vitamins, botanicals, and even beer. Some are formulated to be mild enough for babies, some contain medically active ingredients. Shampoo is a minimally toxic product when used on the hair and scalp but can cause symptoms if swallowed or splashed in the eye.
Dry shampoo products are designed to absorb excess hair oils, mask odors, and add volume to hair. Some dry shampoo products may contain the chemical benzene, most likely as a contaminant. Although benzene exposure is associated with dangerous health effects, there is no evidence that occasional dry shampoo use is harmful to humans.
Botox®, Dysport®, and Xeomin® injections are popular cosmetic procedures. These injections contain a small amount of botulinum toxin. This is the same toxin that causes botulism, but these products contain much less of the toxin than is needed to cause disease in humans.
Nail polish contains chemicals that may have dangerous health effects after high-dose or long-term exposures. There is no evidence that occasional application of nail polish is harmful to pregnant women or fetuses.
Natural products such as peppermint oil have many components. Menthol is the most abundant compound found in peppermint oil. Menthol can cause superficial irritation in small amounts and severe systemic symptoms in large amounts.
Certain brands of sunscreen have been found to contain benzene, but at levels low enough that they are not likely to cause any acute health effects. The use of sunscreen is still recommended, but concerned individuals should avoid products contaminated with benzene.
Carbamide peroxide is most commonly used as an ear wax removal agent, oral rinse, and in home teeth-whitening products. High concentrations of carbamide peroxide can cause serious burns. Rarely, life-threatening toxicity can occur when carbamide peroxide is swallowed and oxygen bubbles form in the body and block blood flow to tissues.
Hair chalks are a fun, temporary way that anyone can use to alter their hair color. Hair chalks are made of substances like bentonite, calcium carbonate, and mica with added pigment. They are considered minimally toxic and not expected to result in serious injury except in the case of allergic reactions in people who are sensitive to the dye.
Most fragrance products contain alcohol; some contain up to 95%. Alcohol can cause serious effects in children. Fragrance products can also cause skin irritation, which will usually go away if you stop using the product.
A hair relaxer is a cream or thick paste that chemically changes the texture of curly hair to make it straighter. If swallowed or upon contact with skin or eyes, hair relaxers can cause burns.
Toxic shock syndrome is a life-threatening disease caused by certain bacteria. People who have open wounds, who have had recent surgery, or who have devices within their bodies may be at risk for toxic shock syndrome.
Misuse of denture creams containing zinc was the cause of zinc poisoning in some denture wearers. Problems with dental creams are uncommon; anyone with symptoms needs a complete evaluation to determine the cause.
Sunscreen and insect repellent can find their way into the eyes, causing pain and irritation. Immediate rinsing with running water is the best first aid.
False eyelashes and lash extensions add an extra "pop" to your eyes. Temporary lashes are attached above the natural eyelashes with a temporary adhesive, while semi-permanent lash extensions are attached to the natural lashes with cyanoacrylate, the adhesive in Super Glue. If either kind of adhesive is used incorrectly, it can cause serious toxicity and injury.
Hair styling products are widely used. In general, they have a low risk of toxicity when used according to the instructions. Scalp, skin, or eye irritation are the most likely adverse effects.
When used as directed, hairspray is minimally toxic. Unintentional eye contact, inhalation, or ingestion of small amounts of hairspray might produce minor irritating effects. Irritation should improve by rinsing the eyes or mouth or getting fresh air. Deliberately swallowing or inhaling hairspray can be very dangerous.
A lick of hand sanitizer won't hurt a child or anyone else. Drinking it can cause alcohol poisoning, which can cause low blood sugar, coma, and seizures – though this is not common.
Hydrogen peroxide is available in several different concentrations. Exposures to small amounts of household (3%) hydrogen peroxide usually cause mild irritation. Higher concentrations can cause burns. Rarely, life-threatening effects can occur when oxygen bubbles from hydrogen peroxide travel to the blood and circulatory system, and block blood flow to tissues.
Micellar water is a cosmetic product that is used to remove dirt, oil, and makeup from the face. Micellar water is made up of water mixed with soap, hydrating chemicals, and perfumes. If swallowed, it is unlikely that a small amount of micellar water will result in poisoning, but it may cause vomiting or diarrhea. Micellar water can also be irritating if it gets in the eyes.
Personal lubricants come in many varieties but are generally safe when used correctly. The most common adverse effect from personal lubricants is irritation. Poisoning is unlikely, but depends on the specific active ingredients, the concentration of the active ingredients, and the amount and route of exposure. To prevent adverse effects, follow the manufacturer's guidelines for proper use.
Tea tree oil has been used as a "natural" remedy for a long time, especially for skin afflictions. There is some scientific evidence that tea tree oil can be effective for certain skin conditions. It is poisonous if swallowed and so should not be used in or around the mouth at all.
A broken mercury-containing thermometer can be toxic if the vapors are inhaled. The risk of poisoning from touching or swallowing mercury from a broken thermometer is low if appropriate clean-up measures are taken.
Dextromethorphan is an over-the-counter cough suppressant found in more than 120 cough and cold products. Recreational abuse has become increasingly common and leads to approximately 6000 emergency room visits a year. Recreational users intentionally exceed recommended doses to experience heightened awareness, altered time perception, and visual hallucinations.
Acetaminophen is a very safe medicine when used in recommended doses to treat pain and fever. But too much acetaminophen can cause liver damage and even death. This has happened when parents didn't understand the concentration or measurements. New formulations of acetaminophen for children make it easier to give the correct dose.
Just about everyone gets colds. Symptoms include a stuffy nose, cough, tiredness, sneezing, sore throat, and muscle aches. Symptoms last for up to two weeks. Most people get better on their own. Treatment is according to symptoms. In general, there is no reliable evidence that alternative medicines prevent or shorten colds.
Home remedies such as saline drops, gentle suctioning, humidity, and fluids are more effective than medicines for young children with coughs and colds. If home remedies don't work, consult the child's health care provider.
Fluoroquinolone antibiotics are associated with serious adverse effects. For this reason, they are not the preferred treatment for many infections, but still have an important role for resistant bacteria and in patients with allergies to other antibiotics.
Antibiotic overdoses are rarely dangerous, but stomach upset and diarrhea may occur. Taking the wrong antibiotic is a problem if someone is allergic to the drug. Misuse of antibiotics is a problem for many reasons: an infection might not be cured, antibiotic-resistant organisms can develop, or, if a specific antibiotic is needed, it might not be effective.
Benzonatate is an anesthetic drug and cough suppressant. When benzonatate capsules are swallowed, the medication acts directly on the lungs to reduce coughing. Benzonatate is only approved for use in individuals 10 years of age and older. Younger children who take benzonatate may experience serious toxicity or even death.
Propylhexedrine (Benzedrex) inhalers can be bought without a prescription for use as a nasal decongestant but can be abused to help study or to get high. They should not be used for these purposes.
Cough and cold medicines are no longer recommended for children under the age of four. Ipecac syrup is no longer recommended for anyone. Mercury thermometers are now known to be a possible health risk if they break.
Natural products such as peppermint oil have many components. Menthol is the most abundant compound found in peppermint oil. Menthol can cause superficial irritation in small amounts and severe systemic symptoms in large amounts.
There is no evidence that cough and cold medicines are safe or effective for young children. There IS evidence that children have been harmed by overdoses of these products. Problems include seizures, coma, and death.
Viral videos on social media promote a trend called “NyQuil™ chicken” that involves cooking chicken in cough and cold medication. This is dangerous and may result in poisoning, both from the ingredients in NyQuil™ and the undercooked chicken.
Vaporizers can add moisture and medication to the air. This can help people who have colds, the flu, or allergies. However, medicated vaporizer liquids are poisonous to swallow.
Rapid home COVID-19 antigen tests contain a small amount of the toxic chemical sodium azide, but the risk of poisoning is low when these tests are used and disposed of properly.

Ivermectin has been safely used to treat parasites (such as heart and intestinal worms) in animals and is approved for use in humans for parasite infections, head lice, and rosacea. It has not been shown to be effective for preventing or treating COVID-19 infection and taking products not intended for human use may lead to serious adverse effects.
Turmeric is a popular spice that has been used for centuries as an herbal medicine due to its antioxidant and anti-inflammatory properties. Despite its popularity, turmeric is actually poorly absorbed by the human body. Although some have advocated for its use as a treatment for COVID-19, data to support the use of turmeric for COVID-19 are lacking.
Janus kinase (“JAK”) inhibitors target and reduce inflammation. One JAK inhibitor, baricitinib, is used to treat COVID-19 infection. The JAK inhibitor oclacitinib (Apoquel®) has not been studied in humans and is not used to treat COVID-19 infection.
Fluvoxamine is a medication that has been used to treat obsessive compulsive disorder and depression. Recent clinical trials have shown that it may be effective for preventing hospitalizations and complications of COVID-19 infection, but it is not quite ready for prime time.
Two old drugs used for malaria, chloroquine and hydroxychloroquine, are being studied for their potential to treat coronavirus disease of 2019 (COVID-19). Side effects from these drugs can be very serious and include irregular heart rhythms that can result in death. Check state COVID-19 website resources and telephone hotlines for more information about COVID-19 in your area.
During the past decade, the use of cleaning wipes has increased substantially. Cleaning wipes are available for a variety of surfaces. Since they are meant to be used with bare hands, they are mostly water and are not commonly associated with toxicity.
Paxlovid® is an oral medication that recently received emergency use authorization from the U.S. Food and Drug Administration (FDA) to prevent severe COVID-19 infection in high-risk individuals who test positive for the virus. While it is generally well tolerated, Paxlovid interacts with many commonly used medications, which can lead to toxicity.
Turmeric is a popular spice that has been used for centuries as an herbal medicine due to its antioxidant and anti-inflammatory properties. Despite its popularity, turmeric is actually poorly absorbed by the human body. Although some have advocated for its use as a treatment for COVID-19, data to support the use of turmeric for COVID-19 are lacking.
Although the seeds of stone fruits naturally contain cyanide, small unintentional ingestions generally do not cause harm. However, swallowing, crushing, or chewing the seeds should be avoided. Swallowing stone fruit pits, kernels, or seeds as complementary or alternative medicine is unsupported by scientific evidence and is dangerous and possibly deadly.
Hangovers are unpleasant symptoms that occur after consumption of alcohol. Even though many products are marketed as hangover treatments, there is no cure for this condition. The best way to prevent a hangover is to avoid drinking excessive amounts of alcohol.
Family, friends, delicious food...Thanksgiving is a happy time of year. Keep your gathering fun and healthy by following some simple guidelines for food preparation and home safety. Take a few minutes to review your Thanksgiving plans. And leave room for the pumpkin pie!
There is some evidence that people who eat a lot of charred or very well done meat have a higher risk of cancer, particularly of the breast, prostate, colon, rectum, and pancreas. To minimize the potential risks, minimize both the amount of time that meat is cooked at high heat and the amount of smoke in contact with the meat.
Sodium is found in table salt, rock salt, pickling salt, and sea salt; soy sauce contains high levels of sodium. Sodium is essential to human health, but too much sodium is poisonous. Sodium poisoning can cause seizures, coma, and death.
The characteristic odor of urine is likely due to the presence of volatile organic compounds, or VOC’s, which are eliminated from the body through the kidneys. Strong urine odors may be related to metabolic conditions, infections, or dehydration.
Bongkrekic acid is a deadly poison that is found in fermented food including wet noodles and presscake from China, Indonesia, and Mozambique. Bongkrekic acid attacks the mitochondria and can cause liver failure, kidney injury, and death. There is no safe dose of this poison.
Ethanol, found in alcoholic beverages, is safe for most adults in moderation. Excessive ethanol intake and consumption of other types of alcohol can be dangerous.
Warm temperatures, sunlight, and added nutrients can cause an overgrowth or “bloom” of algae in bodies of water. Some algae produce toxins that can poison people or animals when they swallow, swim in, or inhale the water or when they eat fish that live there.
Vinegar is a common ingredient in many foods. There is limited evidence that vinegar has legitimate medicinal uses. Vinegar can cause injury if improperly used.
MAO inhibitors are commonly used for the treatment of Parkinson's disease and depression. Serious medical conditions can occur if MAO inhibitors are used in higher doses or taken in overdose. In addition, people who take MAO inhibitors should avoid eating certain foods, to reduce their risk of unwanted side effects.
Needle spiking involves the secret injection of poisonous substances into unsuspecting individuals and represents a form of drug-facilitated crime. It is a scary concept but it is also fortunately a rare occurrence.
Mustard is a popular condiment worldwide, but it can cause allergic reactions in susceptible individuals. Mustard oil is often used for cooking, but only essential mustard oil is approved for use in foods by the United States FDA. Because it may cause health problems in animals, expressed mustard oil is prohibited from use in foods in the United States.
Halloween treats are great. Tricks are not! Go with your children when they trick-or-treat. Look at the goodies before they're eaten. Rinse liquid from glow sticks out of eyes if it's splashed. Drink some water if it's swallowed. And, stick to actual cosmetics meant for the skin when making up.
Botulism is a rare but dangerous type of poisoning that affects the nervous system. Honey can contain botulism spores; these spores release a toxin that can poison infants. The most dangerous effect is paralysis of the diaphragm, which means the infants cannot breathe on their own without a respirator until the disease is cured.
Some ordinary kitchen ingredients can be harmful if children swallow large amounts. Examples include alcohol-based flavoring extracts, oil of wintergreen, and nutmeg. Poppy seeds can cause a positive drug screen if someone eats a lot shortly before a drug test.
When swallowed by dogs, chocolate can cause nausea, vomiting, tremors, and seizures. Effects can begin within a short time. Treatment should begin quickly. There are no specific antidotes for this poisoning in animals.
The “curing” process involves the addition of nitrates and nitrites to meats. While swallowing large amounts of nitrates or nitrites can be dangerous, exposure to the levels typically present in meats is not likely to be harmful.
All parts of the horse chestnut tree are toxic, but the greatest concern is for horse chestnut seeds. These can be easily mistaken for edible chestnuts. Horse chestnut seed pods usually contain only one seed, while edible chestnut pods contain multiple seeds. Eating horse chestnuts can result in serious stomach upset.
You're better off tossing potatoes that have turned green or grown sprouts. Eating them puts you at risk for potential toxicity from solanine and chaconine, two natural toxins found in green or sprouted potatoes.
Raw shellfish can carry bacteria and parasites that can cause life-threatening infections in pregnant women and their unborn children. Avoid eating raw or undercooked shellfish, including oysters, if you are pregnant.
Skittles contain titanium dioxide, a chemical used as a whitening agent in foods. Titanium dioxide is associated with cancer development after inhalational exposures, and it may have effects on DNA and gastrointestinal system function.
Cannabis-infused drinks contain the mind-altering ingredient tetrahydrocannabinol (THC). These drinks, which can be purchased at dispensaries or online, contain various amounts of THC in addition to alcohol, caffeine, or other cannabis derivatives. The safety of these drinks has not been studied extensively in humans.
Arsenic is a known human poison, and can cause severe health effects after high-level or chronic exposures. Arsenic is present in rice and is also found in infant rice cereal. Fortunately, the relatively short duration of time in which infants are given rice cereal in their diets significantly reduces the risk of arsenic poisoning. In addition, providing a balanced diet can also help reduce an infant’s exposure to arsenic.
Xylitol is a sweetener that is safe for humans but poisonous to pets.
Powdered infant formula is not required to be sterile, and in rare cases it may be contaminated with bacteria. Cronobacter contamination of powdered infant formula can cause serious illness in infants, including meningitis and death.
Baking soda is sodium bicarbonate. Both sodium and bicarbonate can cause serious toxicity if too much is swallowed.
Protein bars often contain compounds called sugar alcohols, which are lower in calories than traditional sugars. Sugar alcohols are associated with multiple gastrointestinal side effects including abdominal pain, bloating, and gas.
Cake decorations such as luster dust often add sparkle or color to sweet confections. While some cake decorating products are edible, others may contain heavy metals that can cause poisonous effects when swallowed.
When human skin is exposed to ultraviolet light and certain natural plant-derived substances, a skin condition called “phytophotodermatitis” can occur. This condition is frequently reported after skin exposure to the combination of sunlight and lime juice, and can include skin rashes, blistering, and dark pigmentation. Although it may be painful, phytophotodermatitis generally resolves on its own over time.
Halloween is a holiday synonymous with costume contests and consumption of sugary candy. Eating certain types of sweets, including black licorice and sugar free candy, may result in unwanted toxic effects for trick-or-treaters.
