Iron Supplements The Culprit?
If you take iron supplements, try going off them and see if the pruritus improves. I have had what seemed like aquagenic pruritus for about 12 years and it got worse when my doctor told me to double my iron dose. In fact, after increasing the dose, I started itching even without contact with water. When I stopped taking the ferrous sulfate slow-release supplements, the itching stopped. My iron is not that low anyway, so stopping the supplement was not a big issue. For people who really need the iron, perhaps a different formulation, such as ferrous fumerate or injections would be a solution.
