High-concentration topical capsaicin is used to treat different neuropathic pain states. We present a case in which a 3-year-old child orally ingested capsaicin after touching her mother’s arm that had been treated with a high-concentration capsaicin patch 3 hours earlier. The child suffered extreme pain and swelling of the lips and tongue. After the use of cleansing gel, external cooling, and drinking milk, the pain lessened over half an hour and subsided after 2 hours. This report aims to raise awareness for this formerly unreported mode of oral contamination.
