Oral antihistamines or sedatives may help reduce itching and improve sleep. Topical antihistamines are known to be potent topical sensitizers, and, thus, preparations containing topical diphenhydramine in particular should not be used. Oral gabapentin and pregabalin as well as opioid receptor antagonists may be more efficacious in treating itching due to nummular eczema. [36]
