Generalised pruritus is common in the elderly. Idiopathic 'senile pruritus' is a diagnosis of exclusion, and an underlying systemic disorder should be sought. Thyroid disease, haematological malignancy, iron deficiency, cholestasis or renal impairment may be responsible for pruritus. ⋯ We review the literature concerning the treatment of itch associated with systemic diseases, with particular emphasis on issues relevant to the elderly. Pruritus is a difficult symptom to treat. However, it is hoped that research into the mechanisms underlying the pruritus of systemic disease will allow a better understanding so that we should be able to look forward to more specific and effective therapies in the future.
