What Is Tramadol Hcl Used For?
1. Indications and Usage Section 1 INDICATIONS AND USAGE Tramadol hydrochloride extended-release tablets are indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Limitations of Use Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations [see Warnings and Precautions (5.1)] , reserve tramadol hydrochloride extended-release tablets for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. Tramadol hydrochloride extended-release tablets are not indicated as an as-needed (prn) analgesic.
Dosage and Administration
2. Dosage and Administration Section 2.1 Important Dosage and Administration Instructions Tramadol hydrochloride extended-release tablets should be prescribed only by healthcare professionals who are knowledgeable in the use of potent opioids for the management of chronic pain.
Side Effects (Adverse Reactions)
6. Adverse Reactions The following serious adverse reactions are described in greater detail, in other sections: Addiction, Abuse, and Misuse [see Warnings and Precautions (5.1)] Life-Threatening Respiratory Depression [see Warnings and Precautions (5.3)] Ultra-Rapid Metabolism of Tramadol and Other Risk Factors for Life-Threatening Respiratory Depression in Children [see Warnings and Precautions (5.4)] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5)] Interactions with Benzodiazepines and Other CNS Depressants [see Warnings and Precautions (5.7)] Serotonin Syndrome [see Warnings and Precautions (5.8)] Seizures [see Warnings and Precautions (5.9)] Suicide [see Warnings and Precautions (5.10)] Adrenal Insufficiency [see Warnings and Precautions (5.11)] Severe Hypotension [see Warnings and Precautions (5.13)] Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.15)] Hypersensitivity Reactions [see Warnings and Precautions(5.16)] Withdrawal [see Warnings and Precautions (5.17)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Tramadol hydrochloride extended-release tablet was administered to a total of 3108 patients during studies conducted in the U.S. These included four double-blind studies in patients with osteoarthritis and/or chronic low back pain and one open-label study in patients with chronic non-malignant pain. A total of 901 patients were 65 years or older. The frequency of adverse reactions generally increased with doses from 100 mg to 400 mg in the two pooled, twelve-week, randomized, double-blind, placebo-controlled studies in patients with chronic non-malignant pain (see Table 1). The most common adverse reactions from Table 1 occurring in ≥10% and ≥2 x placebo rate of the patients treated with tramadol hydrochloride extended-release tablets are dizziness (not vertigo), nausea, constipation, headache, somnolence, flushing, pruritus, vomiting, insomnia, and dry mouth. Table 1: Incidence (%) of patients with adverse reaction rates ≥ 5% from two 12-week placebo-controlled studies in patients with moderate to moderately severe chronic pain by dose (N=1811).

Drug Interactions
7. Drug Interactions Table 2 includes clinically significant drug interactions with tramadol hydrochloride extended-release tablets. Inhibitors of CYP2D6 Clinical Impact: The concomitant use of tramadol hydrochloride extended-release tablets and CYP2D6 inhibitors may result in an increase in the plasma concentration of tramadol and a decrease in the plasma concentration of M1, particularly when an inhibitor is added after a stable dose of tramadol hydrochloride extended-release tablets is achieved. Since M1 is a more potent µ-opioid agonist, decreased M1 exposure could result in decreased therapeutic effects, and may result in signs and symptoms of opioid withdrawal in patients who had developed physical dependence to tramadol. Increased tramadol exposure can result in increased or prolonged therapeutic effects and increased risk for serious adverse events including seizures and serotonin syndrome. After stopping a CYP2D6 inhibitor, as the effects of the inhibitor decline, the tramadol plasma concentration will decrease and the M1 plasma concentration will increase which could increase or prolong therapeutic effects but also increase adverse reactions related to opioid toxicity, and may cause potentially fatal respiratory depression [see Clinical Pharmacology (12.3)] . Intervention: If concomitant use of a CYP2D6 inhibitor is necessary, follow patients closely for adverse reactions including opioid withdrawal, seizures, and serotonin syndrome. If a CYP2D6 inhibitor is discontinued, consider lowering tramadol hydrochloride extended-release tablets dosage until stable drug effects are achieved. Follow patients closely for adverse events including respiratory depression and sedation. Examples Quinidine, fluoxetine, paroxetine and bupropion Inhibitors of CYP3A4 Clinical Impact: The concomitant use of tramadol hydrochloride extended-release tablets and CYP3A4 inhibitors can increase the plasma concentration of tramadol and may result in a greater amount of metabolism via CYP2D6 and greater levels of M1. Follow patients closely for increased risk of serious adverse events including seizures and serotonin syndrome, and adverse reactions related to opioid toxicity including potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of tramadol hydrochloride extended-release tablets is achieved. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the tramadol plasma concentration will decrease [see Clinical Pharmacology (12.3)] , resulting in decreased opioid efficacy and possibly signs and symptoms of opioid withdrawal in patients who had developed physical dependence to tramadol. Intervention: If concomitant use is necessary, consider dosage reduction of tramadol hydrochloride extended-release tablets until stable drug effects are achieved. Follow patients closely for seizures and serotonin syndrome, and signs of respiratory depression and sedation at frequent intervals. If a CYP3A4...
Contraindications
4. Contraindications Tramadol hydrochloride extended-release tablets are contraindicated for: all children younger than 12 years of age [see Warnings and Precautions (5.4)] post-operative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Warnings and Precautions (5.4)] . Tramadol hydrochloride extended-release tablets are also contraindicated in patients with: Significant respiratory depression [see Warnings and Precautions (5.3)] Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions (5.12)] Known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions (5.15)] Hypersensitivity to tramadol (e.g., anaphylaxis) [see Warnings and Precautions (5.16), Adverse Reactions (6.2)] Concurrent use of monoamine oxidase inhibitors (MAOIs) or use within the last 14 days[see Drug Interactions (7)].
Overdosage
10. Overdosage Clinical Presentation Acute overdosage with tramadol hydrochloride extended-release tablets can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, QT prolongation, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2)]. Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. Opioid antagonists, such as naloxone,, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to opiod overdose, administer an opioid antagonist. While naloxone will reverse some, but not all, symptoms caused by overdosage with tramadol, the risk of seizures is also increased with naloxone administration. In animals, convulsions following the administration of toxic doses of tramadol hydrochloride extended-release tablets could be suppressed with barbiturates or benzodiazepines but were increased with naloxone. Naloxone administration did not change the lethality of an overdose in mice. Hemodialysis is not expected to be helpful in an overdose because it removes less than 7% of the administered dose in a 4-hour dialysis period. Because the duration of opioid reversal is expected to be less than the duration of action of tramadol in tramadol hydrochloride extended-release tablets, carefully monitor the patient until spontaneous respiration is reliably...
