Why doesn Aveeno baths and Benadryl work for the itching?
ICP itching is different than normal itching because the cause of the itching is internal, and more specifically, it is either directly or indirectly caused by bile salts in the bloodstream. “Normal” itching is caused by histamines and it can often be treated by topical lotions or anti-histamines. Pruritus caused by ICP does not respond to either because of it’s internal nature.
