Itchiness

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