Is there a cure for Aquagenic urticaria?
There’s no cure for aquagenic urticaria. However, there are treatment options available to alleviate symptoms. Antihistamines are medications used to treat allergy-like symptoms. Your doctor may recommend you take a prescription antihistamine to calm your hives after coming into contact with water.
How long does Aquagenic urticaria last?
It was first described by Shelley and Rawnsley in 1964. Wheals occur when a patient’s skin makes contact with any type of water within 30 minutes of exposure, and can last for 30 minutes to 2 hours after cessation of exposure. Aquagenic urticaria most commonly develops on the trunk and upper limbs.
How do you test for an Aquagenic urticaria?
A diagnosis of aquagenic urticaria is typically suspected based on the presence of characteristic signs and symptoms. A “water challenge test” may then be ordered to confirm the diagnosis. During this test, a compress of 35C water is applied to the upper body for 30 minutes.
