Descriptions


Tramadol and acetaminophen combination is used to relieve acute pain severe enough to require an opioid treatment and when other pain medicines did not work well enough or cannot be tolerated. When used together, the combination provides better pain relief than either medicine used alone. In some cases, you may get relief with lower doses of each medicine.

Tramadol belongs to the group of medicines called opioid analgesics (narcotics). It acts in the central nervous system (CNS) to relieve pain. When tramadol is used for a long time, it may become habit-forming (causing mental or physical dependence). Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to side effects when you suddenly stop taking the medicine. Since this medicine is only used for short-term relief of pain, mental and physical dependence will probably not occur.

Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage. Although rare, use of acetaminophen has been reported to lead to liver transplantation and death, usually at high doses and when multiple acetaminophen-containing products have been used.

This medicine is available only under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.

This product is available in the following dosage forms:

  • Tablet

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of tramadol and acetaminophen combination in the pediatric population. It should not be used in children younger than 12 years of age. Safety and efficacy have not been established.

This medicine should not be used to relieve pain after surgery removal of tonsils or adenoids in any children. Severe breathing problems and deaths have been reported in some children who received codeine after tonsil or adenoid surgery.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of tramadol and acetaminophen combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, heart, or lung problems which may require caution and an adjustment in the dose for patients receiving tramadol and acetaminophen combination.

Breastfeeding

Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Proper Use

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence) or cause an overdose. Also, large amounts of acetaminophen may cause liver damage if taken for a long time.

It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of tramadol and acetaminophen combination. This medicine should come with a Medication Guide. Read and follow the instructions carefully. Read it again each time you refill your prescription in case there is new information. Ask your doctor if you have any questions.

Swallow the tablet whole. Do not crush, break, or chew it.

This combination medicine contains acetaminophen (Tylenol®). Carefully check the labels of all other medicines you are using, because they may also contain acetaminophen. It is not safe to use more than 4 grams (4,000 milligrams) of acetaminophen in one day (24 hours), as this may increase the risk for serious liver problems.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • For oral dosage form (tablets):
    • For acute pain:
      • Adults—2 tablets every 4 to 6 hours as needed for up to 5 days. Do not take more than 8 tablets per day.
      • Children 12 years of age and older—Use and dose must be determined by your doctor.
      • Children younger than 12 years of age—Should not be used in these patients.

Missed Dose

If you miss a dose of this medicine, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Drop off any unused narcotic medicine at a drug take-back location right away. If you do not have a drug take-back location near you, flush any unused narcotic medicine down the toilet. Check your local drug store and clinics for take-back locations. You can also check the DEA web site for locations. Here is the link to the FDA safe disposal of medicines website: www.fda.gov/drugs/resourcesforyou/consumers/buyingusingmedicinesafely/ensuringsafeuseofmedicine/safedisposalofmedicines/ucm186187.htm

Precautions

It is very important that your doctor check your or your child's progress at regular visits, especially within the first 24 to 72 hours of treatment, to make sure the medicine is working properly. Blood and urine tests may be needed to check for any unwanted effects.

Do not use this medicine if you are using or have used an MAO inhibitor (MAOI), such as isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], or tranylcypromine [Parnate®] within the past 14 days.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn baby. Check with your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.

Tramadol is highly metabolized in the body. Some people change tramadol to a stronger product (O-desmethyltramadol) more quickly than others. These individuals are called "ultra-rapid metabolizers of tramadol". Contact your doctor immediately if you experience extreme sleepiness, confusion, or shallow breathing. These symptoms may indicate that you are an "ultra-rapid metabolizer of tramadol." As a result, there is too much O-desmethyltramadol in the body and more side effects of O-desmethyltramadol than usual. Children may be especially sensitive to this effect (eg, serious breathing problems, death). Do not give this medicine to:

  • Children younger than 12 years of age.
  • Children younger than 18 years of age who have had surgery removal of tonsils or adenoids.
  • Children 12 to 18 years of age who have a high risk for breathing problems (eg, obstructive sleep apnea, obesity, lung disease).

If a nursing mother is an ultra-rapid metabolizer of tramadol, it could lead to an overdose in the nursing baby and cause very serious side effects.

For nursing mothers using this medicine

  • Talk to your doctor if you have any questions about taking tramadol or about how this medicine may affect your baby.
  • Call your doctor if you become extremely tired and have difficulty caring for your baby.
  • Your baby should generally nurse every 2 to 3 hours and should not sleep more than 4 hours at a time.
  • Check with your doctor, hospital emergency room, or local emergency services (eg, "call 9-1-1") immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.

Check with your doctor right away if you or your child have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause serious allergic reactions, including anaphylaxis, angioedema, or certain skin conditions (eg, Stevens-Johnson syndrome, toxic epidermal necrolysis). These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you or your child have a rash, itching, blistering, peeling, or loosening of the skin, fever or chills, cough, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, trouble breathing or swallowing, unusual tiredness or weakness, or any swelling of your hands, face, mouth, or throat while you are using this medicine.

Check the labels of all nonprescription (over-the-counter [OTC]) or prescription medicines you now take. If any contain acetaminophen or tramadol, check with your doctor. Taking them together with this medicine may cause an overdose.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the doctor or dentist in charge that you or your child are taking this medicine. Serious side effects can occur if your doctor or dentist gives you certain medicines without knowing that you have been taking this medicine.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Your doctor may also give naloxone and other medicines to treat an overdose. Signs of an overdose include: dark urine, difficult or trouble breathing, irregular, fast or slow, or shallow breathing, nausea, vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.

Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with Ultracet® may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Check with your doctor right away if you or your child have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Make sure your doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also, tell your doctor if you have any sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. Let your doctor know if you or anyone in your family has tried to commit suicide.

This medicine may cause some people to become dizzy, drowsy, or may cause trouble with thinking or controlling body movements, which may lead to falls, fractures or other injuries. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

This medicine may cause adrenal gland problems. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. Also, lying down for a while may relieve dizziness or lightheadedness. If this problem continues or gets worse, check with your doctor right away.

Do not change the dose or suddenly stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, such as anxiety, diarrhea, headache, nausea, shivering, sweating, tremors, or trouble sleeping.

Analgesics may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melted bits of ice in your mouth, or a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
