Itching
Geriatrics Essentials: Itching
Age-related changes in the immune system and in nerve fibers may contribute to the high prevalence of itch in older adults. Xerotic eczema is very common among older adults. It is especially likely if itching is primarily on the lower extremities. Severe, diffuse itching in older adults should raise concern for cancer, especially if another etiology is not immediately apparent. When treating older adults, sedation can be a significant problem with antihistamines, so dose reduction may be appropriate. Use of nonsedating antihistamines during the day and sedating antihistamines at night, liberal use of topical ointments and corticosteroids (when appropriate), and consideration of ultraviolet phototherapy can help avoid the complications of sedation.
