Itchiness is the sensation that causes a person the desire or reflex to scratch at their skin. Substances such as opioids, that activate histamine receptors or trigger histamine release can cause this effect. A way to counteract the itchiness in cases of substance use is to take an antihistamine such as DPH (Diphenhydramine).
