Tramadol and acetaminophen (Oral)

TRAM-a-dol hye-droe-KLOR-ide, a-seet-a-MIN-oh-fen

Oral route(Tablet)

Tramadol hydrochloride/acetaminophen exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing tramadol hydrochloride/acetaminophen, and monitor all patients regularly for the development of these behaviors or conditions .Serious, life-threatening, or fatal respiratory depression may occur with use of tramadol hydrochloride/acetaminophen. Monitor for respiratory depression, especially during initiation of tramadol hydrochloride/acetaminophen or following a dose increase.Accidental ingestion of even one dose of tramadol hydrochloride/acetaminophen, especially by children, can result in a fatal overdose of tramadol .Life-threatening respiratory depression and death have occurred in children who received tramadol. Most of the reported cases occurred following tonsillectomy and/or adenoidectomy, and many of the children had evidence of being an ultra-rapid metabolizer of codeine due to a CYP2D6 polymorphism. Tramadol hydrochloride/acetaminophen tablets are contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy. Avoid the use of tramadol hydrochloride/acetaminophen tablets in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of tramadol.Prolonged use of tramadol hydrochloride/acetaminophen during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.The effects of concomitant use or discontinuation of CYP3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol are complex. Use of CYP3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol hydrochloride requires careful consideration of the effects on the parent drug, tramadol, and the active metabolite, M1.Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of tramadol hydrochloride and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation .

Uses For tramadol and acetaminophen

Tramadol and acetaminophen combination is used to relieve acute pain. 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). Physical dependence may lead to side effects when you suddenly stop taking the medicine. Since tramadol and acetaminophen is only used for short-term relief of pain, 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.

Tramadol and acetaminophen is available only with your doctor's prescription.

Before Using tramadol and acetaminophen

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 tramadol and acetaminophen, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to tramadol and acetaminophen 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.

Tramadol and acetaminophen 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.

Breast Feeding

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

Interactions with Medicines

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 tramadol and acetaminophen, 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.

Other Medical Problems

The presence of other medical problems may affect the use of tramadol and acetaminophen. Make sure you tell your doctor if you have any other medical problems, especially:

  • Alcohol abuse, or history of or
  • Brain tumor or
  • Breathing or lung problems (eg, COPD, hypercapnia, hypoxia) or
  • Depression, history of or

  • Liver disease—Use is not recommended in patients with this condition.
  • Lung or breathing problems, severe or
  • Stomach or bowel blockage (eg, paralytic ileus)—Should not be used in patients with these conditions.
  • Seizures, history of or
  • Stomach problems, severe—Use with caution. May make these conditions worse.

Proper Use of tramadol and acetaminophen

Take tramadol and acetaminophen 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 tramadol and acetaminophen 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.

Tramadol and acetaminophen should come with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.

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 tramadol and acetaminophen 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 tramadol and acetaminophen. 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 tramadol and acetaminophen, 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.

Precautions While Using tramadol and acetaminophen

It is very important that your doctor check your progress at regular visits, especially within the first 24 to 72 hours of treatment, to make sure the medicine is working properly and to check for any unwanted effects.

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

Using tramadol and acetaminophen 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 tramadol and acetaminophen.

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 tramadol and acetaminophen 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).

Check with your doctor right away if you 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.

Tramadol and acetaminophen may cause serious allergic reactions, including anaphylaxis, angioedema, or certain skin conditions (Stevens-Johnson syndrome). These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, blistering, peeling, or loosening of the skin, fever or chills, trouble breathing or swallowing, or any swelling of your hands, face, mouth, or throat while you are using tramadol and acetaminophen.

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 tramadol and acetaminophen may cause an overdose.

If you think you or someone else may have taken an overdose of tramadol and acetaminophen, get emergency help at once. Signs of an overdose include dark urine, difficult or troubled 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, shortness of breath, or yellow eyes or skin.

Check with your doctor before using tramadol and acetaminophen 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 tramadol and acetaminophen, 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.

Tramadol and acetaminophen 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.

Make sure your doctor knows about all the other medicines you are using. Tramadol and acetaminophen may increase your risk for seizures (convulsions). It may also cause a serious condition called serotonin syndrome when taken with some medicines. This especially includes medicines used to treat depression (eg, citalopram, fluoxetine, sertraline, Cymbalta®, Effexor®, Lexapro®, Pristiq®) or medicine to treat migraine headaches (eg, eletriptan, frovatriptan, rizatriptan, zolmitriptan). Check with your doctor right away if you have the following symptoms of serotonin syndrome: agitation, confusion, diarrhea, excitement while talking that is not normal, fever, overactive reflexes, poor coordination, restlessness, shivering, sweating, trembling or shaking that you cannot control, or twitching.

Tramadol and acetaminophen 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.

Tramadol and acetaminophen 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 tramadol and acetaminophen affects you.

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 tramadol and acetaminophen 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 tramadol and acetaminophen may cause infertility (unable to have children). Talk with your doctor before using tramadol and acetaminophen 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.
