Percocet is usually prescribed for the management of moderate to severe pain. It contains a combination of acetaminophen and oxycodone, which are both pain relievers. Acetaminophen is used to reduce fever and relieve mild to moderate pain, while oxycodone is an opioid pain medication that works by changing the way the brain and nervous system respond to pain. It is important to only take Percocet as directed by a healthcare provider, as it can be habit-forming and has the potential for misuse and addiction.
