What is Ultracet?
Ultracet contains a combination of tramadol and acetaminophen. Tramadol is a narcotic-like pain reliever. Acetaminophen is a less potent pain reliever that increases the effects of tramadol.
Ultracet is used to treat moderate to severe pain.
Ultracet may also be used for purposes not listed in this medication guide.
You should not use Ultracet if you have recently used alcohol, sedatives, tranquilizers, or other narcotic medications.
Do not take more Ultracet than your recommended dose. An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of your skin or eyes).
In rare cases, acetaminophen may cause a severe skin reaction. Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Ultracet may be habit-forming and should be used only by the person it was prescribed for. Never share this medication with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Keep track of the amount of medicine used from each new bottle. Ultracet is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
What happens if I miss a dose?
Since Ultracet is taken as needed for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An Ultracet overdose can be fatal.
The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.
Overdose symptoms may also include shallow breathing, slow heartbeat, extreme weakness, cold or clammy skin, feeling light-headed, fainting, seizure, or coma.
What should I avoid?
Do not drink alcohol while you are taking Ultracet. Alcohol may cause a dangerous decrease in your breathing when used together with Ultracet. Alcohol may also increase your risk of liver damage while taking acetaminophen.
Ultracet may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.
