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.
Tramadol can slow or stop your breathing, and may be habit-forming. Use only your prescribed dose. Never share Ultracet with another person.
An acetaminophen overdose 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).
MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Before taking this medicine
You should not use Ultracet if you are allergic to acetaminophen (Tylenol) or tramadol (Ultram), or if you have recently used alcohol, sedatives, tranquilizers, or other narcotic medications.
Seizures have occurred in some people taking Ultracet. Your risk of a seizure may be higher if you have any of these conditions:
a history of drug or alcohol addiction;
a history of epilepsy or other seizure disorder;
a history of head injury;
a metabolic disorder;
an infection of your brain or spinal cord, such as meningitis or encephalitis;
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others); or
if you have taken an MAO inhibitor (isocarboxazid, linezolid, methylene blue injections, phenelzine, rasagiline, selegiline, tranylcypromine) within the past 14 days.
Some medicines can interact with tramadol and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
To make sure Ultracet is safe for you, tell your doctor if you have:
liver disease, cirrhosis, a history of alcoholism, or if you drink more than 3 alcoholic beverages per day;
asthma or other breathing disorder;
a stomach disorder;
a history of depression, mental illness, or suicide attempt; or
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others).
It is not known whether Ultracet will harm an unborn baby. If you use the medicine while you are pregnant, your baby could become dependent on tramadol. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Acetaminophen and tramadol can pass into breast milk and may harm a nursing baby. You should not breast-feed while using Ultracet.
How should I take Ultracet?
Take Ultracet exactly as prescribed by your doctor. Follow all directions on your prescription label. Never take this medicine in larger amounts, or for longer than prescribed. An overdose can damage your liver or cause death. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
The maximum amount of Ultracet is 2 tablets per dose, or 8 tablets per day. Do not take Ultracet for longer than 5 days in a row.
Ultracet may be habit forming. Never share it with another person. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away this medicine is against the law.
You may take Ultracet with or without food, but take it the same way each time.
Do not stop using Ultracet suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using the medicine.
Store at room temperature away from moisture and heat.
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 used 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 use 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 while taking Ultracet?
Do not drink alcohol. Dangerous side effects or death could occur.
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.
Ultracet side effects
Get emergency medical help if you have signs of an allergic reaction to Ultracet: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Stop taking Ultracet and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
