How Camphor continues to poison children
Exactly three years ago today, the New York City Department of Health and Mental Hygiene issued an alert about use of camphor products around children. The alert mentioned children who were hospitalized with seizures after ingestion and contact with over-the-counter (OTC) camphor products. Exposures to camphor continue to occur. So here’s another warning for parents to keep camphor products away from kids.
Exactly three years ago today, the New York City Department of Health and Mental Hygiene issued an alert about use of camphor products around children. The alert mentioned children who were hospitalized with seizures after ingestion and contact with over-the-counter (OTC) camphor products. I checked with New York City Poison Control, as well as the Poison Control Center at Children’s Hospital of Philadelphia, and exposures to camphor continue to occur. So here’s another warning for parents to keep camphor products away from kids.
Camphor is rapidly absorbed into the body from the skin, gastrointestinal tract, and respiratory tract. It comes as pure camphor for use as an insect or moth repellent but in other forms, it’s applied for itching and inhalation for upper respiratory congestion. It is an ingredient of anti-itch products applied to the skin like Benadryl Itch Stopping Gel, balms for muscle pain like Tiger Balm and cold medicines like Vicks VapoRub. Its strong aromatic odor can repel insects and moths, for which camphor is used as a repellent.
One New York case involved a 15-month-old child who presented to the emergency department (ED) with intractable vomiting followed by a generalized seizure approximately 40 minutes after licking a cube of camphor. The parents purchased the camphor (called “alcanfor” in Spanish) at a local botanica to treat the child’s cold. The camphor had been placed in a bowl of water on the floor of the child’s room and added to the humidifier water.
Some camphor is sold in blocks like these.
Surprisingly, Dr. Muller mentioned that while moth balls were thought to no longer be available commercially, they do still get calls now and then about ingestions of camphor from moth balls. Other poisonings are associated with camphor sold as small white cubes packaged in clear plastic (see photo). Such straight camphor is still available in bodegas, botanicas, discount stores, as well as from some pharmacies or on-line.
The latest national data are from American Association of Poison Control Centers National Poison Data System, published in the December 2009 Clinical Toxicology. Nationally, 10,808 exposures to camphor were reported to U.S. Poison Control Centers in 2008. Of these, 8,686 were in children under age 6 years and the vast majority were judged to be unintentional. Treatment in a health care facility was necessary in 1,013. Fortunately, none died, but at least 86 were harmed. Seizures or pulmonary aspiration are the major hazards.
This advice given by the New York City Health Department is worth repeating:
• Read product labels. Keep all camphor products out of the reach of children.
• Do not scatter camphor products around the house or use them in humidifiers.
• Do not use camphor for pest control. Use only safer pest control products such as boric acid, gels and baits for cockroaches, and glue traps or bait in enclosed tamper-proof containers for rodents.
