Hydrocodone belongs to a class of drugs known as opioids, which work by binding to opioid receptors in the brain and spinal cord, blocking pain signals. Along with its pain-relieving properties, hydrocodone also induces feelings of euphoria and relaxation, making it susceptible to misuse. When taken as prescribed, hydrocodone can provide relief for individuals suffering from acute or chronic pain. However, prolonged use or misuse can lead to tolerance, dependence, and addiction.
