Molecular Mechanisms of Opioid-Induced Hyperalgesia

Quick fact

Opioid-induced hyperalgesia can occur at both low and high doses, and it can even make non-painful stimuli (like light touch) become painful—a condition called allodynia.

You've likely heard that opioids like morphine are powerful painkillers. But what if the very drug given to relieve pain could make you more sensitive to it over time?
