Version July 2025
Because the use of tapentadol 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 and reassess all patients regularly for the development of these behaviors or conditions.
Health care providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription.
Serious, life-threatening, or fatal respiratory depression may occur with use of tapentadol, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of tapentadol are essential. Instruct patients to swallow tapentadol ER tablets whole; crushing, chewing, or dissolving tapentadol ER can cause rapid release and absorption of a potentially fatal dose of tapentadol.
Accidental ingestion of even one dose of tapentadol, especially by children, can result in a fatal overdose of tapentadol.
If opioid use is required for an extended period of time in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome (NOWS), which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery.
Instruct patients not to consume alcoholic beverages or use prescription or nonprescription products that contain alcohol while taking tapentadol ER. The coingestion of alcohol with tapentadol ER may result in increased plasma tapentadol levels and a potentially fatal overdose of tapentadol.
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 tapentadol and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.
Dosage guidance:
Safety: Doses should be titrated to appropriate effect; use lowest effective dose for the shortest duration to meet treatment goals. Assess need and discuss availability of naloxone for emergent treatment of opioid overdose with patient and/or caregiver upon initiating and renewing treatment.
Acute pain, moderate to severe:
Note: Patients must be able to swallow tablets. For patients with a BMI >97th percentile for age, use the maximum daily dose for body weight at the 97th percentile for a given age.

(For additional information see "Tapentadol: Drug information")
Dosage guidance:
Safety: Consider prescribing naloxone or nalmefene for patients with factors associated with an increased risk for overdose, such as history of overdose or substance use disorder, patients with sleep-disordered breathing, higher opioid dosages (≥50 morphine milligram equivalents [MME]/day orally), and/or concomitant benzodiazepine use (Ref).
Dosing: Dosing provided is based on typical doses and some patients may require higher or lower doses. Individualize dosing and dosing intervals based on patient-specific factors (eg, severity of pain, comorbidities, degree of opioid experience/tolerance) and titrate to patient-specific treatment goals (eg, improvement in function and quality of life, decrease in pain using a validated pain rating scale). Use the lowest effective dose for the shortest period of time (Ref).
Clinical considerations: Opioids may be part of a comprehensive, multimodal, patient-specific treatment plan for managing moderate to severe pain. Maximize nonopioid analgesia (when appropriate) prior to initiation of opioid analgesia (Ref).
Acute pain:
Immediate release:
Day 1: Oral: 50 to 100 mg every 4 to 6 hours as needed; may administer a second dose ≥1 hour after the first dose if adequate pain relief is not attained with the first dose; maximum total daily dose on first day: 700 mg/day.
Day 2 and subsequent dosing: Oral: 50 to 100 mg every 4 to 6 hours as needed; maximum total daily dose: 600 mg/day.
Conversion from tapentadol IR to tapentadol ER: Oral: Convert using same total daily dose but divide into 2 equal doses and administer every 12 hours. Maximum total daily ER dose: 500 mg/day.
Extended release:
Opioid naive (use as the first opioid analgesic or use in patients who are not opioid tolerant): Oral: Initial: 50 mg every 12 hours
Conversion from tapentadol IR to tapentadol ER: Oral: Convert using same total daily dose but divide into 2 equal doses and administer every 12 hours. Maximum total daily ER dose: 500 mg/day.
Conversion from other opioids to tapentadol ER: Initial: Oral: 50 mg every 12 hours
Conversion from methadone to tapentadol ER: Oral: Close monitoring is required when converting methadone to another opioid. Ratio between methadone and other opioid agonists varies widely according to previous dose exposure. Methadone has a long half-life and can accumulate in the plasma.
Dosage titration: Oral: May titrate every 3 days in increments of up to 100 mg/day (eg, up to 50 mg twice daily) based on response and tolerability. Maximum total daily ER dose: 500 mg/day.
Neuropathic pain, diabetic peripheral neuropathy:
Note: Tapentadol ER is not recommended due to a high risk for substance use disorder and safety concerns compared to modest pain reduction (Ref).
Extended release:
Opioid naive (use as the first opioid analgesic or use in patients who are not opioid tolerant): Initial: Oral: 50 mg every 12 hours.
Conversion from tapentadol IR to tapentadol ER: Oral: Convert using same total daily dose but divide into 2 equal doses and administer every 12 hours. Maximum total daily ER dose: 500 mg/day.
Conversion from other opioids to tapentadol ER: Initial: Oral: 50 mg every 12 hours.
Conversion from methadone to tapentadol ER: Oral: Close monitoring is required when converting methadone to another opioid. Ratio between methadone and other opioid agonists varies widely according to previous dose exposure. Methadone has a long half-life and can accumulate in the plasma.
Dosage titration: Oral: May titrate every 3 days in increments of up to 100 mg/day (eg, up to 50 mg twice daily) based on response and tolerability. Maximum total daily ER dose: 500 mg/day.
Discontinuation of therapy: When discontinuing chronic opioid therapy, the dose should be gradually tapered down. An optimal universal tapering schedule for all patients has not been established. Individualize tapering based on discussions with patient to minimize withdrawal, while considering patient-specific goals and concerns and the opioid's pharmacokinetics. Proposed initial schedules range from slow (eg, 10% reduction per week or 10% reduction per month depending on duration of long-term therapy) to rapid (eg, 25% to 50% reduction every few days) (Ref). Slower tapers may be appropriate after long-term use (eg, >1 year), whereas more rapid tapers may be appropriate in patients experiencing severe adverse effects. During tapering, patients may be at an increased risk of overdose if they return to their original (or higher) opioid dose or use illicit opioids, due to rapid loss of tolerance; consider prescribing naloxone or nalmefene. Monitor carefully for signs/symptoms of withdrawal. If the patient displays withdrawal symptoms, consider slowing the taper schedule; alterations may include increasing the interval between dose reductions, decreasing amount of daily dose reduction, pausing the taper and restarting when the patient is ready, and/or coadministration of an alpha-2 agonist (eg, clonidine) to blunt autonomic withdrawal symptoms and other adjunctive agents to treat GI symptoms and muscle spasms, as needed. Continue to offer nonopioid analgesics as needed for pain management during the taper (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
CrCl ≥30 mL/minute: No dosage adjustment necessary.
CrCl <30 mL/minute: Use not recommended.
Mild impairment (Child-Pugh class A): No dosage adjustment necessary.
Moderate impairment (Child-Pugh class B):
Immediate release: Initial: 50 mg every 8 hours or longer; maximum total daily dose: 150 mg per 24 hours. Further treatment for maintenance of analgesia may be achieved by either shortening or lengthening the dosing interval.
Extended release: Initial: 50 mg every 24 hours or longer; maximum total daily dose: 100 mg/day.
Severe impairment (Child-Pugh class C): Use not recommended.

Concerns related to adverse effects:
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Hyperalgesia: Opioid-induced hyperalgesia (OIH) has occurred with short-term and prolonged use of opioid analgesics. Symptoms may include increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily nonpainful stimuli; symptoms may be suggestive of OIH if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. Consider decreasing the current opioid dose or opioid rotation in patients who experience OIH.
• Hypotension: May cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), or drugs which may exaggerate hypotensive effects (including phenothiazines or general anesthetics). Monitor for symptoms of hypotension following initiation or dose titration. Avoid use in patients with circulatory shock.
• Respiratory depression: Fatal respiratory depression may occur. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. Patients and caregivers should be educated on how to recognize respiratory depression and the importance of getting emergency assistance immediately (eg, calling 911) in the event of known or suspected overdose.
• Serotonin syndrome: Potentially life-threatening serotonin syndrome (SS) has occurred with concomitant use of tapentadol and serotonergic agents (eg, SSRIs, SNRIs, triptans, TCAs, fentanyl, lithium, tramadol, buspirone, St John's wort, tryptophan) or agents that impair metabolism of serotonin (eg, MAO inhibitors intended to treat psychiatric disorders, other MAO inhibitors [ie, linezolid and intravenous methylene blue]). Monitor patients closely for signs of SS such as mental status changes (eg, agitation, hallucinations, delirium, coma); autonomic instability (eg, tachycardia, labile blood pressure, diaphoresis); neuromuscular changes (eg, tremor, rigidity, myoclonus); GI symptoms (eg, nausea, vomiting, diarrhea); and/or seizures. Discontinue treatment (and any concomitant serotonergic agent) immediately if signs/symptoms arise.
Disease-related concerns:
• Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenocortical insufficiency: Use with caution in patients with adrenal insufficiency, including Addison disease. Long-term opioid use may cause secondary hypogonadism, which may lead to mood disorders and osteoporosis (Brennan 2013).
• Biliary tract impairment: Use caution in patients with biliary tract dysfunction or acute pancreatitis; opioids may cause spasm of the sphincter of Oddi.
• CNS depression/coma: Avoid use in patients with impaired consciousness or coma as these patients are susceptible to intracranial effects of CO2 retention.
• Delirium tremens: Use with caution in patients with delirium tremens.
• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.
• Hepatic impairment: Serum concentrations are increased in hepatic impairment; use with caution in patients with moderate hepatic impairment (dosage adjustment required). Not recommended for use in severe hepatic impairment.
• Mental health conditions: Use opioids with caution for chronic pain in patients with mental health conditions (eg, depression, anxiety disorders, post-traumatic stress disorder) due to potential increased risk for opioid use disorder and overdose; more frequent monitoring is recommended (CDC [Dowell 2022]).
• Obesity: Use with caution in patients who are morbidly obese.
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture.
• Psychosis: Use with caution in patients with toxic psychosis.
• Renal impairment: Use with caution in patients with mild to moderate renal impairment. Not recommended for use in severe renal impairment.
• Respiratory disease: Use with caution and monitor for respiratory depression in patients with significant chronic obstructive pulmonary disease or cor pulmonale, and patients having a substantially decreased respiratory reserve, hypoxia, hypercarbia, or preexisting respiratory depression, particularly when initiating and titrating therapy; critical respiratory depression may occur, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Seizures: Use caution in patients with a history of seizures or conditions predisposing patients to seizures; may cause or exacerbate preexisting seizures.
• Sleep-related disorders: Use with caution in patients with sleep-related disorders, including sleep apnea, due to increased risk for respiratory and CNS depression. Monitor carefully and titrate dosage cautiously in patients with mild sleep-disordered breathing. Avoid opioids in patients with moderate to severe sleep-disordered breathing (CDC [Dowell 2022]).
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Benzodiazepines or other CNS depressants: Concomitant use may result in respiratory depression and sedation, which may be fatal. Consider prescribing naloxone or nalmefene for emergency treatment of opioid overdose in patients taking benzodiazepines or other CNS depressants concomitantly with opioids.
• Ethanol use: Concomitant use may increase tapentadol plasma levels resulting in fatal overdose.
Special populations:
• Cachectic or debilitated patients: Use with caution in cachectic or debilitated patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages. Consider the use of nonopioid analgesics in these patients.
• Older adult: Use opioids with caution in older adults; may be more sensitive to adverse effects. Clearance may also be reduced in older adults (with or without renal impairment) resulting in a narrow therapeutic window and increased adverse effects. Monitor closely for adverse effects associated with opioid therapy (eg, respiratory and CNS depression, falls, cognitive impairment, constipation) (CDC [Dowell 2022]). Consider the use of alternative nonopioid analgesics in these patients when possible.
• Neonates: Neonatal withdrawal syndrome: Signs and symptoms include irritability, hyperactivity and abnormal sleep pattern, high-pitched cry, tremor, vomiting, diarrhea and failure to gain weight. Onset, duration, and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn.
Dosage form specific issues:
• Extended release tablets: Therapy should only be prescribed by healthcare professionals familiar with the use of opioids as part of the management of chronic pain.
Other warnings/precautions:
• Abrupt discontinuation/withdrawal: Abrupt discontinuation in patients who are physically dependent to opioids has been associated with serious withdrawal symptoms, uncontrolled pain, attempts to find other opioids (including illicit), and suicide. Use a collaborative, patient-specific taper schedule that minimizes the risk of withdrawal, considering factors such as current opioid dose, duration of use, type of pain, and physical and psychological factors. Monitor pain control, withdrawal symptoms, mood changes, suicidal ideation, and for use of other substances and provide care as needed. Concurrent use of mixed agonist/antagonist analgesics (eg, pentazocine, nalbuphine, butorphanol) or partial agonist (eg, buprenorphine) analgesics may also precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists.
• Abuse/misuse/diversion: Use with caution in patients with a history of substance use disorder; potential for drug dependency exists. Other factors associated with increased risk for misuse include concomitant depression or other mental health conditions, higher opioid dosages, or taking other CNS depressants. Consider offering naloxone or nalmefene prescriptions in patients with an increased risk for overdose, such as history of overdose or substance use disorder, higher opioid dosages (≥50 morphine milligram equivalents [MME]/day orally), concomitant benzodiazepine use, and patients at risk for returning to a high dose after losing tolerance (CDC [Dowell 2022]).
• Accidental exposure: Extended release tablets: Accidental ingestion of even one dose, especially in children, can result in a fatal overdose of tapentadol.
• Appropriate use: Outpatient setting: Opioids should not be used as first-line therapy for acute (<1-month duration), subacute (1- to 3-month duration), or chronic pain (>3-month duration [outside of end-of-life or palliative care, active cancer treatment, sickle cell disease, or medication-based opioid use disorder treatment]). Preferred management includes nonpharmacologic therapy and nonopioid therapy (eg, nonsteroidal anti-inflammatory drugs, acetaminophen, certain antiseizure medications, and antidepressants) as appropriate for the specific condition. If opioid therapy is initiated, it should be combined with nonpharmacologic and nonopioid therapy, as appropriate. Prior to initiation, known risks and realistic benefits of opioid therapy should be discussed with the patient. Therapy should be initiated at the lowest effective dosage using IR opioids (instead of ER/long-acting opioids). For the treatment of acute pain, therapy should only be given for the expected duration of pain severe enough to require opioids and prescribed as needed (not scheduled). For the treatment of subacute and chronic pain, realistic treatment goals for pain/function should be established, including consideration for discontinuation if benefits do not outweigh risks. Therapy should be continued only if clinically meaningful improvement in pain/function outweighs risks. Risk to patients increases with higher opioid dosages. Dosages ≥50 MME/day are likely to not have increased benefit to pain relief or function relative to overall risk to patients; before increasing dosage to ≥50 MME/day, readdress pain and reassess evidence of individual benefits and risks (CDC [Dowell 2022]).
• Naloxone/nalmefene access: Discuss the availability of naloxone or nalmefene with all patients who are prescribed opioid analgesics, as well as their caregivers, and consider prescribing it to patients who are at increased risk of opioid overdose. These include patients who are also taking benzodiazepines or other CNS depressants, have an opioid use disorder (OUD) (current or history of), or have experienced opioid-induced respiratory depression/opioid overdose. Additionally, health care providers should consider prescribing naloxone or nalmefene to patients prescribed medications to treat OUD; patients at risk of opioid overdose even if they are not taking an opioid analgesic or medication to treat OUD; and patients taking opioids, including methadone or buprenorphine for OUD, if they have household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose. Inform patients and caregivers on options for obtaining naloxone or nalmefene (eg, by prescription, directly from a pharmacist, a community-based program) as permitted by state dispensing and prescribing guidelines. Educate patients and caregivers on how to recognize respiratory depression, proper administration of naloxone or nalmefene, and getting emergency help.
• Optimal regimen: An opioid-containing analgesic regimen should be tailored to each patient's needs and based upon the type of pain being treated (acute versus chronic), the route of administration, degree of tolerance for opioids (naive versus chronic user), age, weight, and medical condition. The optimal analgesic dose varies widely among patients; doses should be titrated to pain relief/prevention.
• Surgery: Opioids decrease bowel motility; monitor for decrease bowel motility in postoperative patients receiving opioids. Use with caution in the perioperative setting; individualize treatment when transitioning from parenteral to oral analgesics.

Management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate (immediate release: FDA approved in ages ≥6 years, weight ≥40 kg, and adults); management of severe and persistent pain that requires an extended treatment period with a daily opioid analgesic and for which alternative treatment options are inadequate (extended release: FDA approved in adults); management of severe and persistent neuropathic pain associated with diabetic peripheral neuropathy that requires an extended treatment period with daily opioid analgesic and for which alternative treatments are inadequate (extended released: FDA approved in adults). Note: Although FDA approved in adults, tapentadol ER is not recommended for treatment of diabetic peripheral neuropathy indication due to a high risk for substance use disorder and safety concerns compared to modest pain reduction (Ref).
Tapentadol may be confused with traMADol
The Institute for Safe Medication Practices (ISMP) includes this medication among its list of drug classes (opioids, all formulations and routes of administration) which have a heightened risk of causing significant patient harm when used in error (High-Alert Medications in Acute Care, Community/Ambulatory Care, and Long-Term Care Settings).
Tapentadol is identified in the Screening Tool of Older Person's Prescriptions (STOPP) criteria as a potentially inappropriate medication in older adults (≥65 years of age) due to an increased risk of falls and exacerbation of constipation. Opioids are not recommended as first-line for mild pain or for long-term treatment of osteoarthritis. Short acting opioids should be available for breakthrough pain in patients on long-acting opioids (O’Mahony 2023).

Chronic opioid use may cause hypogonadism and hyperprolactinemia which may decrease fertility in patients of reproductive potential. Menstrual cycle disorders (including amenorrhea), erectile dysfunction, and impotence have been reported. The incidence of hypogonadism may be increased with the use of opioids in high doses or long-acting opioid formulations. It is not known if the effects on fertility are reversible. Monitor patients on long-term therapy (de Vries 2020; Gadelha 2022)
Consider family planning, contraception, and the effects on fertility prior to prescribing opioids for chronic pain to patients who could become pregnant (ACOG 2017; CDC [Dowell 2022]).
Opioids cross the placenta.
Maternal use of opioids may be associated with poor fetal growth, stillbirth, and preterm delivery (CDC [Dowell 2022]). Opioids used as part of obstetric analgesia/anesthesia during labor and delivery may temporarily affect the fetal heart rate (ACOG 2019).
Neonatal abstinence syndrome (NAS)/neonatal opioid withdrawal syndrome (NOWS) may occur following prolonged in utero exposure to opioids (CDC [Dowell 2022]). NAS/NOWS may be life-threatening if not recognized and treated and requires management according to protocols developed by neonatology experts. Presentation of symptoms varies by opioid characteristics (eg, immediate release, sustained release), time of last dose prior to delivery, drug metabolism (maternal, placental, and infant), net placental transfer as well as other factors (AAP [Hudak 2012]; AAP [Patrick 2020]). Clinical signs characteristic of withdrawal following in utero opioid exposure include excessive crying or easily irritable, fragmented sleep (<2 to 3 hours after feeding), tremors, increased muscle tone, or GI dysfunction (hyperphagia, poor feeding, feeding intolerance, watery or loose stools) (Jilani 2022). NAS/NOWS occurs following chronic opioid exposure and would not be expected following the use of opioids at delivery (AAP [Patrick 2020]).
Monitor infants of mothers on long-term/chronic opioid therapy for symptoms of withdrawal. Symptom onset reflects the half-life of the opioid used. Monitor infants for at least 3 days following exposure to immediate-release opioids; monitor for at least 4 to 7 days following exposure to sustained-release opioids (AAP [Patrick 2020]; CDC [Dowell 2022]). Monitor newborns for excess sedation and respiratory depression when opioids are used during labor.
When opioids are needed to treat acute pain in pregnant patients, the lowest effective dose for only the expected duration of pain should be prescribed (CDC [Dowell 2022]).
Opioid use for pain following vaginal or cesarean delivery should be made as part of a shared decision-making process. A stepwise multimodal approach to managing postpartum pain is recommended. A low-dose, low-potency, short-acting opioid can be used to treat acute pain associated with delivery when needed (ACOG 2021).
Opioids are not preferred for the treatment of chronic noncancer pain during pregnancy; consider strategies to minimize or avoid opioid use. Advise pregnant patients requiring long-term opioid use of the risk of NAS/NOWS and provide appropriate treatment for the neonate after delivery. NAS/NOWS is an expected and treatable condition following chronic opioid use during pregnancy and should not be the only reason to avoid treating pain with an opioid in pregnant patients (ACOG 2017; CDC [Dowell 2022]). Do not abruptly discontinue opioids during pregnancy; taper prior to discontinuation when appropriate, considering the risks to the pregnant patient and fetus if maternal withdrawal occurs (CDC [Dowell 2022]).
