About Tramadol:

  • Tramadol is a strong painkiller. It's used to treat moderate to severe pain, for example after an operation or a serious injury.
  • It's also used to treat long-standing pain when weaker painkillers no longer work.
  • Tramadol is available only on prescription. It comes as tablets, capsules and liquid drops that you swallow. It can also be given by injection but this is usually only done in hospital.

Key Facts:

  • Tramadol works by blocking pain signals from travelling along the nerves to the brain.
  • The most common side effects of tramadol are feeling sick and dizzy.
  • It's possible to become addicted to tramadol, but this is rare if you're taking it to relieve pain and your doctor is reviewing your treatment regularly.
  • It's best not to drink alcohol with tramadol as you're more likely to get side effects like feeling sleepy.
  • Tramadol is also called by the brand names:
    • Invodol
    • Larapam
    • Mabron
    • Maneo
    • Marol
    • Maxitram
    • Oldaram
    • Tilodol
    • Tradorec
    • Tramquel
    • Tramulief
    • Zamadol
    • Zeridame
    • Zydol
  • Tramadol can be taken by adults and children aged 12 and over.
  • The dose can vary but you should not normally take more than 400mg a day.

Tramadol (sold under the brand name Ultram) is a narcotic analgesic proposed for moderate to severe pain. Tramadol and its O-desmethyl metabolite (M1) are selective, weak OP3-receptor agonists. Opiate receptors are coupled with G-protein receptors and function as both positive and negative regulators of synaptic transmission via G-proteins that activate effector proteins. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine, and noradrenaline is inhibited. The analgesic properties of Tramadol can be attributed to norepinephrine and serotonin reuptake blockade in the CNS, which inhibits pain transmission in the spinal cord. The (+) enantiomer has the higher affinity for the OP3 receptor and preferentially inhibits serotonin uptake and enhances serotonin release. The (-) enantiomer preferentially inhibits norepinephrine reuptake by stimulating alpha(2)-adrenergic receptors. Tramadol is used primarily to treat mild-severe pain, both acute and chronic. Its analgesic effects take about one hour to come into effect and 2 h to 4 h to peak after oral administration with an immediate-release formulation. On a dose-by-dose basis, tramadol has about one-tenth the potency of morphine and is approximately equally potent when compared to pethidine and codeine. The most common adverse effects of tramadol include nausea, dizziness, dry mouth, indigestion, abdominal pain, vertigo, vomiting, constipation, drowsiness, and headache. Compared to other opioids, respiratory depression and constipation are considered less of a problem with tramadol.

This medication is used to help relieve moderate to moderately severe pain. Tramadol is similar to opioid analgesics.

It works in the brain to change how your body feels and responds to pain.

Used for:

Pain, chronic pain, neuropathic pain disorder characterized by stifftender & painful muscles

Before Using:
Tell your doctor or pharmacist your medical history, especially of:

  • brain disorders (such as head injury, tumor, seizures)
  • breathing problems (such as asthma, sleep apnea, chronic obstructive pulmonary disease-COPD)
  • kidney disease
  • liver disease
  • mental/mood disorders (such as confusion, depression, suicidal thoughts)
  • personal or family history of a substance use disorder (such as overuse of or addiction to drugs/alcohol)
  • stomach/intestinal problems (such as blockage, constipation, diarrhea due to infection, paralytic ileus)
  • difficulty urinating (such as due to enlarged prostate)
  • gallbladder disease
  • disease of the pancreas (pancreatitis)
  • obesity


This drug may make you dizzy or drowsy.

Alcohol or marijuana (cannabis) can make you more dizzy or drowsy.

Do not drive, use machinery, or do anything that needs alertness until you can do it safely.

Avoid alcoholic beverages.

Talk to your doctor if you are using marijuana (cannabis).

Tramadol may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation.

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using tramadol safely.


Tramadol has a risk for abuse and addiction, which can lead to overdose and death. Tramadol may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you take the smallest dose of tramadol that works, and take it for the shortest possible time.

The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you take the wrong dose/strength.

Taking this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death.

Other medications can affect the removal of tramadol from your body, which may affect how tramadol works.

Be sure you know how to take tramadol and what other drugs you should avoid taking with it. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Tramadol Hydrochloride drug usage

32nd most prescribed medicine in the United States for 2017

WHO Report:

Substance identification:
Tramadol is a white, bitter, crystalline and odourless powder soluble in water and ethanol. Tramadol is marketed as the hydrochloride salt and is available in a variety of pharmaceutical formulations for oral(tablets, capsules), sublingual (drops), intranasal, rectal (suppositories), intravenous, subcutaneous, and intramuscular administration. It is also available in combination with acetaminophen (paracetamol). Preparations of tramadol are available as immediate-and extended-release formulations.

Effects on Central Nervous System:
Tramadol has been detected in a number of deaths. It is often present along with other drugs, including opioids, benzodiazepines and antidepressants,but fatalities have also been reported due to tramadol alone.

Dependence Potential:
Evidence suggests that the development of physical dependence to tramadol is dose-related, and administration of supra-therapeutic doses leads to a similar dependence profile to morphine and other opioids such as oxycodone and methadone. There are reports of considerable number of people with tramadol dependence seeking help. Withdrawal symptoms include those typical of opioids such as pain, sweating, diarrhoea and insomnia as well as symptoms not normally seen with opioids and related to noradrenergic and serotonergic activity, such as hallucinations, paranoia, confusion and sensory abnormalities. Low dose tramadol use over extended periods is associated with a lower risk of dependence.

Consistent with its opioid mechanism of action, human brain imaging has shown that tramadol activates brain reward pathways associated with abuse. While reports from people administered tramadol in controlled settings have shown that it is identified as opioid-like and tramadol has reinforcing effects in experienced opioid users, these effects may be weaker than those produced by opioids such as morphine and may be partially offset by unpleasant effects of tramadol such as sweating, tremor, agitation, anxiety and insomnia. The oral route of administration has been the predominant mode of tramadol abuse as it results in a greater opioid effect compared to other routes.It is unlikely that tramadol will be injected to any significant extent.

The Committee was concerned by the increasing evidence for tramadol abuse in a number of countries in diverse regions, in particular the widespread abuse of tramadol in many low to middle income countries. Equally concerning was the clear lack of alternative analgesics for moderate to severe pain for which tramadol is used.

Tramadol overdose can cause acute liver failure. Pharmacologic use of tramadol has not been associated with cases of clinically apparent drug induced liver disease.

Tramadol Hepatotoxicity:
Serum aminotransferase levels can be elevated in a small proportion of patients receiving tramadol, particularly with high doses. Intentional and accidental overdoses of tramadol can cause respiratory arrest as well as acute liver failure, several fatal instances of which have been reported. In these cases, however, the liver injury may have been caused by shock, hypoxia or ischemia secondary to the respiratory arrest. Liver injury attributed to tramadol overdose has also been associated with hyperammonemia, lactic acidosis and hepatic steatosis, suggestive of direct mitochondrial injury. In some situations, acute liver failure after tramadol overdose may be related to acetaminophen taken separately or in combination with tramadol. Clinically apparent idiosyncratic liver injury with recommended doses of tramadol has not been reported and must be rare, if it occurs at all.

E Likelihood score: E (unlikely cause of clinically apparent liver injury).

Harm reduction advice:
If you choose to use tramadol, taking some simple steps can reduce some of the risks and help you stay safer:

  • Stay within recommended doses. The majority of serious side-effects from tramadol occur when using more than the recommended daily dosage. However, tramadol overdose can occur even from taking smaller doses, often in combination with other drugs.
  • Don't use alone. Serious side effects such as seizures and low blood sugar can occur in certain people. Try to ensure that other people are with you when using tramadol, especially if it's your first time using.
  • Avoid mixing drugs. Try to avoid mixing tramadol with other drugs, including prescription medication. Fatal overdose on tramadol alone is possible but is much more common when tramadol is mixed with other drugs, especially other central nervous system depressants. Mixing tramadol with prescribed medications can also lead to a range of dangerous and life-threatening conditions.
  • Avoid injecting tablets and capsules. Injecting this form of tramadol whether IV, IM or subcutaneous risks overdose and death, and the fillers and binders in tramadol tablets when injected can cause local tissue necrosis, infection, pulmonary granulomas and increased risk of endocarditis and valvular heart injury.


A synthetic opioid analgesic, tramadol is used to treat moderate pain and can be considered a medium-strength opioid. Tramadol also has the unusual effect of being a serotonin releasing agent and a serotonin reuptake inhibitor, and as a consequence should not be taken in excess due to the risk of serotonin syndrome. Risk of seizures above 300mg doses.

NOTE: Tramadol has a ceiling dose, where recreational effects are not increased. Risk of seizure at doses over 300mg. Tramadol decreases the seizure threshold, use extreme caution. Dosing insufflated is ineffective.

Black Box Warnings:

Opioid analgesic risk evaluation and mitigation strategy (REMS)

  • To ensure that benefits of opioid analgesics outweigh risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a REMS for these products; under requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers
  • Healthcare providers are strongly encouraged to:
    • Complete a REMS-compliant education program
    • Counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products
    • Emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist
    • Consider other tools to improve patient, household, and community safety

Addiction, abuse, and misuse

  • Risk of opioid addiction, abuse, and misuse, which can lead to overdose and death; assess each patient's risk prior to prescribing and monitor all patients regularly for the development of these behaviors or conditions

Life-threatening respiratory depression

  • Serious, life-threatening, or fatal respiratory depression may occur
  • Monitor for respiratory depression, especially during initiation or following a dose increase

Accidental ingestion

  • Accidental ingestion of even 1 dose, especially by children, can result in a fatal overdose

Neonatal opioid withdrawal syndrome

  • Prolonged use 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

Ultra-rapid metabolism and other risk factors for life-threatening respiratory depression in children

  • Life-threatening respiratory depression reported in children who received tramadol; some reported cases occurred following tonsillectomy and/or adenoidectomy, and at least one case, the child had evidence of being an ultra-rapid metabolizer of tramadol due to a CYP2D6 polymorphism; therapy is contraindicated in children <12 years and in children <18 years of age following tonsillectomy and/or adenoidectomy; avoid use in adolescents 12-18 years who have other risk factors that may increase sensitivity to respiratory depressant effects

Interactions with Drugs Affecting Cytochrome P450 Isoenzymes

  • Effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol are complex.
  • Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors requires careful consideration of the effects on the parent drug, tramadol, and the active metabolite, M1

Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants

  • Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death; reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate; limit dosages and durations to minimum required; follow patients for signs and symptoms of respiratory depression and sedation


  • Qdolo should not be used in children younger than 12 years of age and to relieve pain after surgery (eg, surgery to remove adenoid or tonsil) in children.
  • Appropriate studies have not been performed on the relationship of age to the effects of Rybix ODT and Ryzolt in children younger than 16 years of age. Safety and efficacy have not been established.
  • Conzip extended-release capsules and Ultram tablets should not be used in children younger than 12 years of age. It 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 tramadol after tonsil or adenoid surgery.

  • Appropriate studies have not been performed on the relationship of age to the effects of Ultram ER extended-release tablets in the pediatric population. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of tramadol in the elderly.

However, elderly patients are more likely to have unwanted side effects (eg, constipation, lightheadedness, dizziness, or fainting, stomach upset, weakness) and age-related liver, kidney, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving tramadol.


Summary of Use During Lactation:
The excretion of tramadol into milk is low and even lower amounts of the active metabolite, O-desmethyltramadol, are excreted. With usual maternal dosage, the amount excreted into breastmilk is much less than the dose that has been given to newborn infants for analgesia. A study of breastfeeding in breastfed newborn infants found no adverse effects attributable to tramadol. Although tramadol is unlikely to adversely affect nursing infant, the U.S. Food and Drug Administration and the manufacturer recommend against the use of tramadol during breastfeeding. If tramadol is used, monitor infants for increased sleepiness (more than usual), difficulty breastfeeding, breathing difficulties or limpness, and contact a physician immediately if any of these occur.

Effects in Breastfed Infants:
Seventy-five breastfed infants whose mothers were breastfeeding and taking tramadol 100 mg every 6 hours following a cesarean section were compared to 75 matched infants at 2 to 4 days of age. Forty-nine percent of the mothers taking tramadol and all of the control mothers were taking other opiates (primarily oxycodone) and 61% of and 58%, respectively, also were taking a nonsteroidal antiinflammatory agent (primarily diclofenac). Examination by a pediatrician revealed no difference between the groups using the Neurologic and Adaptive Capacity Score.

Effects on Lactation and Breastmilk:
Tramadol can increase serum prolactin. However, the prolactin level in a mother with established lactation may not affect her ability to breastfeed. A randomized study compared tramadol and naproxen for post-cesarean section pain. Patients received the drugs either on a fixed schedule or as needed. No difference in breastfeeding rates were seen among the groups. In a study in China, women with a scheduled cesarean section were randomized to receive intravenous patient-controlled analgesia with either sufentanil or tramadol. Postpartum prolactin levels were higher in the tramadol group (348 mcg/L) than in the sufentanil group (314 mcg/L). The onset of lactation was sooner in the tramadol group (21.4 hours) than in the sufentanil group (25.1 hours). Both of these difference were statistically significant.

Injectable tramadol is not available in the United States.
