From the Guidelines
Tramadol should be prescribed at a maximum daily dose of 400 mg for immediate-release formulations (100 mg 4 times a day), or 300 mg/day for extended-release formulations, for adults with normal hepatic and renal function. The dosage should be adjusted for older adults (75 years and older) and those with hepatic and/or renal dysfunction to reduce the risk of seizures 1.
Key Considerations
- Tramadol is a weak mu-opioid receptor agonist with some norepinephrine and serotonin reuptake inhibition, providing pain relief through multiple mechanisms.
- Treatment should begin at the lowest effective dose, especially in elderly patients or those with liver or kidney problems.
- Side effects may include dizziness, nausea, constipation, and drowsiness.
- Patients should be aware that tramadol carries risks of dependence and withdrawal symptoms, and should not be stopped abruptly after prolonged use.
- It should not be combined with alcohol, other opioids, or certain antidepressants due to potential serious interactions.
Monitoring and Adjustments
- Regular monitoring by a healthcare provider is necessary to assess effectiveness and adjust dosage as needed.
- The NCCN panel recommends using tramadol with caution or avoiding it in patients taking other serotonergic or monoamine oxidase inhibitors (MAOI)-like medications (eg, TCAs, SSRIs, and MAOIs) due to risk of serotonin syndrome 1.
- A Cochrane review of tramadol (with or without acetaminophen) concluded that limited evidence supports the use of tramadol for treatment of cancer pain and that tramadol is likely not as effective as morphine in this setting 1.
From the FDA Drug Label
DOSAGE & ADMINISTRATION Adults (17 years of age and over) For patients with moderate to moderately severe chronic pain not requiring rapid onset of analgesic effect, the tolerability of tramadol hydrochloride tablets, USP can be improved by initiating therapy with a titration regimen: The total daily dose may be increased by 50 mg as tolerated every 3 days to reach 200 mg/day (50 mg q.i.d.) After titration, tramadol hydrochloride tablets, USP 50 to 100 mg can be administered as needed for pain relief every 4 to 6 hours not to exceed 400 mg/day For the subset of patients for whom rapid onset of analgesic effect is required and for whom the benefits outweigh the risk of discontinuation due to adverse events associated with higher initial doses, tramadol hydrochloride tablets, USP 50 mg to 100 mg can be administered as needed for pain relief every four to six hours, not to exceed 400 mg per day Individualization of Dose Good pain management practice dictates that the dose be individualized according to patient need using the lowest beneficial dose. In all patients with creatinine clearance less than 30 mL/min, it is recommended that the dosing interval of tramadol hydrochloride tablets be increased to 12 hours, with a maximum daily dose of 200 mg. Since only 7% of an administered dose is removed by hemodialysis, dialysis patients can receive their regular dose on the day of dialysis. The recommended dose for adult patients with cirrhosis is 50 mg every 12 hours. In general, dose selection for an elderly patient over 65 years old should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function and of concomitant disease or other drug therapy. For elderly patients over 75 years old, total dose should not exceed 300 mg/day.
The recommended dosage of tramadol for pain management is:
- 50 to 100 mg every 4 to 6 hours as needed, not to exceed 400 mg/day
- For patients with creatinine clearance less than 30 mL/min, the dosing interval should be increased to 12 hours, with a maximum daily dose of 200 mg
- For dialysis patients, the regular dose can be administered on the day of dialysis
- For adult patients with cirrhosis, the recommended dose is 50 mg every 12 hours
- For elderly patients over 65 years old, the dose should be cautious, starting at the low end of the dosing range, and for those over 75 years old, the total dose should not exceed 300 mg/day 2
From the Research
Recommended Dosage and Treatment Guidelines for Tramadol
The recommended dosage and treatment guidelines for tramadol (Ultram) for pain management vary depending on the specific formulation and the patient's condition.
- For extended-release tramadol tablets (Ultram ER), the dosage is typically initiated at 100 mg once daily and may be increased by 100 mg every 5 days until a maximum dose of 300 mg per day is reached 3.
- For patients transitioning from short-acting tramadol to tramadol ER, the total daily dose of short-acting tramadol can be calculated and tramadol ER can be started at the nearest lower 100-mg dose increment 3.
- Tramadol ER has been shown to be effective in reducing pain in patients with chronic pain from osteoarthritis and improving pain-related sleep parameters, joint stiffness, and physical function 3.
- The efficacy and safety profile of tramadol ER, as well as its low potential for abuse, make it a viable therapeutic option for the management of chronic/persistent nonmalignant pain in some patients 3, 4.
Administration and Pharmacokinetics
- Tramadol is available in various formulations, including drops, capsules, sustained-release formulations, suppositories, and solutions for injection 5.
- After oral administration, tramadol is rapidly and almost completely absorbed, with a bioavailability of 87-95% compared to capsules 5.
- The mean elimination half-life of tramadol is approximately 6 hours, and it is mainly metabolized by O- and N-demethylation and conjugation reactions 5.
Safety and Tolerability
- Tramadol is generally well-tolerated, with common adverse effects including dizziness, nausea, sedation, dry mouth, and sweating 6, 5.
- Tramadol has a lower incidence of adverse events compared to other opioid analgesics and is not associated with gastrointestinal, renal, or cardiovascular complications 4.
- The risk of dependence and abuse with tramadol is considered low, although it is not entirely excluded, especially with long-term use 6, 4.
