I’m not sure if you still suffer from neuropathic itch, but wanted to share my possible solution. I suffered with chronic hives for about four or five months, a few years ago. I went to an allergist, dermatologist, and then a rheumatologist. What they came up with was an allergy tablet, accompanied with Benadryl and an acid reducer. The Benadryl gets rid of one type of histamine and the acid reducer, believe it or not, takes care of the other histamine. The acid reducer is Cimetidine. I finally got relief from the hives, but several years later, I developed the neuropathy itch. I already took Benadryl in the evenings so whenever the itch would develop, I would take a couple of the acid reducers. Within about 20 to 30 minutes, time for the medication to get into my system, the itch went away. I keep this by my bedside all the time. I buy the generic brand from Walmart. I hope that this helps you or anyone else who is suffering from this type of itch.
