Dialysis pruritus: effect of cimetidine.

The effect of oral Cimetidine compared to a classic antihistaminic and to a placebo was evaluated, under the double hypothesis of its anti-PTH and anti-pruritus action, in a population of patients recently included in Hemodialysis that were asked about the incidence and intensity of pruritus according to a scored questionnaire made for this purpose. No different efficacy of Cimetidine versus the antihistaminic classic and the placebo was observed in our study.
