Contraindications

OTC labeling: When used for self-medication, do not use over large areas of the body or with a bandage.

Warnings/Precautions

Special populations:

• Pediatric: The American Academy of Pediatrics suggests that camphor be avoided in pediatric patients because of its lack of efficacy and the well-documented toxicity that may occur with use (AAP 1994). Although toxicity most often results from oral ingestion of topical or inhalation products, combined dermal and inhalation exposure has resulted in toxicity (Love 2004).

Other warnings/precautions:

• Appropriate use: For external use only; avoid contact with eyes.

• Self-medication (OTC use): When used for self-medication (OTC use), do not use on deep puncture wounds, animal bites, serious burns, or for >7 days. Consult health care provider if condition worsens or gets better and returns after a few days.

Warnings: Additional Pediatric Considerations

Camphor may cause significant and potentially life-threatening adverse effects in children; most reported cases are with accidental oral ingestions; however, toxicity has also been reported with topical application in an infant. Mild toxicity may cause GI effects (eg, nausea, vomiting) or burning sensation; however, severe effects such as restlessness, delirium, seizures, and fatal respiratory depression possibly leading to death can occur with doses as low as 500 mg. Onset of toxicity can occur as rapidly as 5 to 15 minutes after ingestion. Adults appear to be able to tolerate higher ingestions; however, oral ingestion is not recommended (AAP 1994; Khine 2009; Love 2004; Manoguerra 2006; Mathen 2018). Due to the increased potential for toxicity, the limited beneficial effects of camphor, and the availability of safer alternative agents for all approved camphor uses, experts recommend camphor should be used with extreme caution, if at all, in pediatric patients (AAP 1994; Love 2004; PPA [Meyers 2020]).
