Summary

The effects of diphenhydramine and diphenhydramine plus ethanol on response to intradermal histamine and on mental performance were assessed in twelve male volunteers. A significant impairment of histamine skin response was found with diphenhydramine. This response was unaffected by ethanol. Ethanol improved performance with a tracking test compared with diphenhydramine alone, the effect was not potentiated by the combination. None of the treatments had a significant effect on a digit symbol substitution test. Co-administration of ethanol and diphenhydramine caused greater impairment of performance in a serial seven subtraction test than diphenhydramine alone. There was no correlation between central and peripheral effects of the antihistamine.
