Aspirin is in a group of drugs called salicylates (sa-LIS-il-ates). It works by reducing substances in the body that cause pain, fever, and inflammation.

Oxycodone is in a group of drugs called narcotic pain relievers.

Percodan is used to relieve moderate to severe pain.

Percodan may also be used for purposes other than those listed in this medication guide.

Most important: Aspirin should not be given to a child or teenager who has a fever, especially if the child also has flu symptoms or chicken pox. Aspirin can cause a serious and sometimes fatal condition called Reye’s syndrome in children.

Stop using Percodan and call your doctor at once if you have any symptoms of bleeding in your stomach or intestines. Symptoms include black, bloody, or tarry stools, and coughing up blood or vomit that looks like coffee grounds.

Oxycodone may be habit-forming and should be used only by the person this medicine was prescribed for. Keep the medication in a secure place where others cannot get to it.

Avoid drinking alcohol while taking Percodan. Alcohol may increase your risk of stomach bleeding while taking aspirin.

Tell your doctor if the medicine seems to stop working as well in relieving your pain.
