Celecoxib / Tramadol Dosage

Medically reviewed by Last updated on Jun 6, 2022.

Applies to the following strengths: 56 mg-44 mg

Usual Adult Dose for Pain

2 tablets orally every 12 hours as needed for pain


  • Patients should be monitored closely for respiratory depression, especially within the first 24 to 72 hours of starting therapy.

Use: For the management of acute pain that is severe enough to require an opioid analgesic and for which alternative therapies are inadequate

Renal Dose Adjustments

Severe renal dysfunction: Not recommended.


  • The pharmacokinetics and tolerability of this drug have not been studied in patients with renal dysfunction.

Liver Dose Adjustments

Moderate or severe liver dysfunction: Not recommended.


  • The pharmacokinetics and tolerability of this drug have not been studied in patients with liver dysfunction.

Dose Adjustments

Poor Metabolizers of CYP450 2C9 Substrates:

  • Celecoxib is administered starting with half the lowest recommended dose in patients known/suspected to be poor CYP450 2C9 metabolizers (i.e., CYP450 2C9*3/*3), based on genotype or history/experience with other CYP450 2C9 substrates (e.g., warfarin, phenytoin).
  • Because this combination drug is not available in lower strengths of celecoxib, it is not recommended in patients known/suspected to be poor CYP450 2C9 metabolizers.

Safe Reduction or Discontinuation of Therapy:
  • This drug should not be abruptly discontinued in patients who may be physically dependent on opioids.
  • Rapid discontinuation of opioid analgesics in physically dependent patients has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide.
  • Rapid discontinuation has been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse; patients may attempt to treat their pain or withdrawal symptoms with illicit opioids (e.g., heroin) and other substances.
  • When deciding to decrease the dose or discontinue therapy in an opioid-dependent patient, various factors should be considered, including the total daily opioid dose (including this drug) the patient has been taking, the duration of therapy, the type of pain being treated, and the patient's physical and psychological attributes.
  • It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic.
  • When discontinuing opioid analgesics due to a suspected substance use disorder, the patient should be evaluated and treated, or referred for evaluation and treatment of the substance use disorder; treatment should include evidence-based approaches (e.g., medication assisted treatment of opioid use disorder); complex patients with comorbid pain and substance use disorders may benefit from referral to a specialist.
  • While there are no standard opioid tapering schedules suitable for all patients, good clinical practice dictates a patient-specific plan to taper the opioid dose gradually.
  • For patients taking this drug who are physically opioid-dependent, starting the taper in small increments (e.g., no greater than 10% to 25% of the total daily opioid dose) is recommended to avoid withdrawal symptoms, and dose-lowering should proceed at 2- to 4-week intervals.
  • Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper.
  • The patient may need to be given a reduced dosing schedule of this drug to accomplish a successful taper.
  • The patient should be reassessed frequently to manage pain and withdrawal symptoms, should they emerge; common withdrawal symptoms (including restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, mydriasis) and other signs/symptoms (including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, increased blood pressure/respiratory rate/heart rate) may develop.
  • If withdrawal symptoms occur, the taper may need to be paused for a period of time or the opioid analgesic dose may need to be increased to the prior dose, and then a slower taper should continue.
  • Patients should be monitored for any changes in mood, emergence of suicidal thoughts, or use of other substances.
  • When managing patients taking opioid analgesics (especially those treated for a long duration and/or with high doses for chronic pain), a multimodal approach to pain management (including mental health support, if needed) should be prepared before starting an opioid analgesic taper.
  • A multimodal approach to pain management may optimize the treatment of chronic pain, as well as assist with the successful tapering of the opioid analgesic.


The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for all opioid analgesics used in the outpatient setting. It includes a medication guide and elements to assure safe use. For additional information:


  • ADDICTION, ABUSE, AND MISUSE: This drug exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death; each patient's risk should be assessed before prescribing this drug and all patients should be monitored regularly for the development of such behaviors and conditions.
  • OPIOID ANALGESIC REMS: To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the US FDA has required a REMS for these products; under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to health care providers. Health care 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; and consider other tools to improve patient, household, and community safety.
  • LIFE-THREATENING RESPIRATORY DEPRESSION: Serious, life-threatening, or fatal respiratory depression may occur with use of this drug; monitoring for respiratory depression, especially during initiation of this drug, is recommended.
  • ACCIDENTAL INGESTION: Accidental ingestion of even 1 dose of this drug (especially by children) can be fatal.
  • CARDIOVASCULAR THROMBOTIC EVENTS: NSAIDs cause an increased risk of serious cardiovascular thrombotic events (including myocardial infarction and stroke), which can be fatal; this risk may occur early in therapy and may increase with duration of use. This drug is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.
  • GASTROINTESTINAL (GI) BLEEDING, ULCERATION, AND PERFORATION: NSAIDs cause an increased risk of serious GI side effects (including bleeding, ulceration, and perforation of stomach or intestines), which can be fatal; such events can occur at any time during use and without symptoms. Elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.
  • ULTRA-RAPID METABOLISM OF TRAMADOL AND OTHER RISK FACTORS FOR LIFE-THREATENING RESPIRATORY DEPRESSION IN CHILDREN: Life-threatening respiratory depression and death have occurred in children who received tramadol; some of the reported cases followed tonsillectomy and/or adenoidectomy, and in at least 1 case, the child had evidence of being an ultra-rapid metabolizer of tramadol due to a CYP450 2D6 polymorphism. This drug is contraindicated in children younger than 12 years and in children younger than 18 years following tonsillectomy and/or adenoidectomy. Use of this drug should be avoided 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.
  • NEONATAL OPIOID WITHDRAWAL SYNDROME: Prolonged use of this drug during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated; it requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant patient, the patient should be apprised of the risk of neonatal opioid withdrawal syndrome and health care providers should ensure that appropriate treatment will be available.
  • INTERACTIONS WITH DRUGS AFFECTING CYP450 ISOENZYMES: The effects of concomitant use or discontinuation of CYP450 3A4 inducers, CYP450 3A4 inhibitors, or CYP450 2D6 inhibitors with tramadol are complex; use of such agents 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 CNS depressants (including alcohol) may result in profound sedation, respiratory depression, coma, and death. Concomitant prescribing of this drug and benzodiazepines/other CNS depressants should be reserved for use in patients for whom alternative treatment options are inadequate; treatment should be limited to the minimum duration; and patients should be followed for signs/symptoms of respiratory depression and sedation.

  • All patients younger than 12 years
  • Postoperative pain management in children younger than 18 years after tonsillectomy and/or adenoidectomy
  • Significant respiratory depression
  • In the setting of CABG surgery
  • Acute or severe bronchial asthma in an unmonitored setting or without resuscitative equipment
  • Known/suspected GI obstruction (including paralytic ileus)
  • Previous hypersensitivity (e.g., anaphylaxis reactions, serious skin reactions) to either active component, opioids, sulfonamides, or to any of the ingredients
  • Concomitant use of monoamine oxidase inhibitors or use within the last 14 days
  • History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs (severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients)

Safety and efficacy have not been established in patients younger than 18 years.
