Why Does Percocet Lead to Addiction?

Percocet works on pain with a two-prong approach. Acetaminophen is thought to decrease pain by impacting the pain signals to the brain. While it hasn’t been fully proven how this happens, researchers believe it may raise the threshold at which the brain processes pain.

The oxycodone in Percocet reduces pain by binding to the opioid receptors in the central nervous system. This relieves pain and produces a feeling of calm or euphoria that is common with other opioids, such as fentanyl and heroin.

This relief from pain and stress can reinforce repeated use, especially if someone has a major injury and is worried that the pain will come back if they stop using Percocet. With repeated use, Percocet tolerance builds, and it’s common to start taking higher or more frequent doses to continue experiencing the same feel-good effects. Some people also use faster delivery methods, such as snorting, or mix Percocet with other substances, such as alcohol or benzodiazepines.

Over time, the body gets used to having Percocet, and you may experience withdrawal symptoms if you try to reduce or stop your use.
