What is Aquagenic Pruritus?
Aquagenic pruritus is a skin disease characterized by the development of severe itches on the skin when water touches it. This condition doesn’t cause visible rashes or hives, but the individual will feel severe itching and discomfort.
Aquagenic Pruritus: What Causes It?
The cause of Aquagenic Pruritus is still unknown; it is seen as a reaction the body gives out. Studies have shown that mast cell degranulation, localised release of acetylcholine, and increased cutaneous fibrinolytic activity all play a role in aquagenic pruritus.

- Polycythemia rubra vera (in over 45% of patients)

- Hypereosinophilic syndrome
- Antimalarial drug treatments like hydroxychloroquine and chloroquine
