Percocet Patient Tips
How it works
Percocet combines acetaminophen and oxycodone, two different pain-relief medicines with two different mechanisms of action. Acetaminophen works by blocking the effects of a specific enzyme, know as cyclo-oxygenase (COX). Oxycodone binds to specific receptors called opioid receptors that block pain signals on their way to the brain.
Effective for the management of severe pain unresponsive to other treatment options.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- May cause nausea and vomiting, dizziness, and headache (oxycodone component).
- May impair reaction skills and affect a person's ability to drive or operate machinery (oxycodone component). Avoid alcohol.
- Rarely, serious, life-threatening, breathing problems (oxycodone component).
- Rarely, liver failure especially at dosages greater than 4000mg/day (acetaminophen component).
- Avoid taking extra acetaminophen while taking Percocet.
- Risk of addiction, dependence, and withdrawal reactions (oxycodone component). Also risk of abuse.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Tell your doctor if you experience any breathing difficulties, wheezing, itching, or facial swelling.
- Tell your doctor if you think you have become addicted to Percocet.
- Do not take more than the recommended dose.
- Be careful not to double on on other medicines containing similar ingredients (for example, acetaminophen is present in some cough and cold remedies).
Response and Effectiveness
- Maximum effect of oxycodone component reached in 1.8 hours and duration of activity lasts for 3-4 hours. Acetaminophen effect reached within 30-60 minutes of administration and analgesic effect lasts around 3 to 4 hours.
