OBJECTIVE: To describe a case of a child with altered mental status followi
ng the topical administration of doxepin.
CASE SUMMARY: A five-year-old Hispanic girl was brought tb the emergency de
partment because she was difficult to arouse at school. She had recently de
veloped a generalized eczematous rash for which she. was prescribed doxepin
hydrochloride 5% cream. An entire tube (30 g) of doxepin dream was applied
in the 24 hours prior to presentation. The patient was responsive only to
noxious stimuli, with no focal neurologic abnormalities. She was decontamin
ated and observed in a pediatric intensive care unit. By 18 hours after pre
sentation, she had fully recovered and was discharged.
CONCLUSIONS: Topical doxepin, available as a 5% cream, is indicated for the
treatment of pruritus secondary to eczematous dermatoses in adults. Dimini
shed skin integrity and the application of a massive quantity of doxepin 5%
cream to a large body surface area contributed to the toxicity in this chi
ld. Since the safety and efficacy of doxepin cream has not been established
in children younger than 12 years, it should be used with caution in this
population.
