Understanding Tramadol: The "Safer" Opioid That Isn't
What Is Tramadol and Why Is It So Widely Prescribed?
Tramadol is a synthetic opioid medication commonly prescribed for moderate to severe acute and chronic pain management, and its use has surged dramatically in recent years, making it one of the most frequently prescribed opioids in the United States. The FDA classified tramadol as a Schedule IV controlled substance in July 2014, acknowledging its potential for misuse and addiction. However, despite this classification, tramadol prescriptions continue to rise—driven largely by the widespread misconception that it carries fewer side effects and is safer and less addictive than other short-acting opioids.[1]
Tramadol operates through dual mechanisms of action: it functions as an opioid agonist binding to μ-opioid receptors in the central nervous system, while simultaneously augmenting serotonergic and noradrenergic neurotransmission, similar to the mechanism of action of venlafaxine antidepressants. The medication's main active metabolite, O-desmethyltramadol (M1), is itself an opioid. This dual-action profile distinguishes tramadol from traditional opioids and has been cited as justification for its inclusion in numerous clinical pain management guidelines across multiple medical specialties.[2]

The Persistent Myth of Tramadol Safety
Despite widespread perception among both physicians and patients that tramadol represents a "safer" opioid alternative with lower addiction potential, robust scientific evidence does not substantiate these claims. In fact, research demonstrates that people receiving tramadol after acute surgery have similar or sometimes higher risks of prolonged opioid use compared to those receiving other short-acting opioids. The 2025 BMJ analysis notes that although previous systematic reviews included tramadol, none had offered a comprehensive evaluation of both its effectiveness and safety across different types of chronic pain conditions, leaving crucial questions unanswered.[1][3]
The 2025 Systematic Review: Methodology and Key Findings
Research Design and Trial Selection
To address significant gaps in existing evidence, researchers conducted a comprehensive systematic review searching research databases for randomized clinical trials published up to February 2025 that compared tramadol with placebo in patients with chronic pain, including cancer-related pain. The analysis followed rigorous methodological standards including the Trial Sequential Analysis and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, which emphasizes quality of evidence and practical importance of findings.[1]
The final analysis included 19 randomized placebo-controlled clinical trials involving 6,506 participants with various chronic pain conditions. The distribution of studies across pain types included five studies examining neuropathic pain (nerve pain), nine focused on osteoarthritis, four investigated chronic low back pain, and one studied fibromyalgia. Study participants had an average age of 58 years, with ages ranging from 47 to 69 years. Most studies utilized tablet formulations, with only one trial testing a topical cream application. Treatment periods ranged from 2 to 16 weeks, with follow-up periods lasting 3 to 15 weeks.[1]

Primary Findings: Minimal Pain Relief with Significant Risks
When results were combined through meta-analysis, the data demonstrated that tramadol did reduce pain, but only slightly—with a mean reduction of 0.93 points on the numerical rating scale (NRS), falling below the predetermined minimal clinically important difference of 1.0 point. This distinction is crucial for understanding real-world clinical significance. A reduction of 0.93 points is so small that most patients would likely not perceive a meaningful difference in their daily pain experience. The researchers rated the evidence for pain reduction as "low certainty," indicating substantial uncertainty about the true magnitude of tramadol's pain-relieving effects.[1]
Eight of the trials tracked serious adverse events during follow-up periods of 7 to 16 weeks, revealing that tramadol was associated with approximately double the risk of harm compared with placebo. This nearly two-fold increase in serious side effects represents a substantial safety concern. The researchers rated the evidence for serious adverse events as "moderate certainty," indicating a more robust evidence base for the harm findings compared to the benefit findings.[1]
Serious Cardiovascular and Medical Adverse Events
Cardiac Events: The Primary Safety Concern
The doubling of serious adverse event risk with tramadol was largely driven by a significantly higher proportion of "cardiac events," including chest pain, coronary artery disease, and congestive heart failure. This pattern is particularly alarming given that cardiovascular disease already represents a leading cause of mortality globally. The mechanism through which tramadol increases cardiac risk involves multiple pathways: increased oxidative stress, mitochondrial dysfunction, sympathomimetic effects from noradrenergic reuptake inhibition, and direct effects on cardiac electrolyte handling.[1]
Recent research investigating the cardiovascular toxicity of tramadol in animal models found that long-term tramadol treatment was associated with significant increases in oxidative stress parameters and cardiac damage, including myocardial fibrosis. These findings suggest that chronic tramadol use initiates progressive cardiac damage that accumulates over time. The clinical trials included in the systematic review had follow-up periods of only 7 to 16 weeks—potentially insufficient time for all cardiac complications to manifest, suggesting that the true magnitude of tramadol-related cardiac risk may be underestimated.[4]

Cancer Risk and Other Serious Adverse Events
Tramadol use was also associated with a heightened risk of certain cancers; however, researchers cautioned that this finding is "questionable" due to the short follow-up periods in available clinical trials. Cancer development typically requires years or decades of exposure, and trial follow-up periods of weeks to months are insufficient for detecting true carcinogenic effects. This limitation highlights a broader problem: most clinical trials of pain medications track only short-term outcomes, leaving long-term safety questions inadequately addressed.[1]
Common Side Effects: Across-the-Board Tolerability Issues
Mild but Frequent Adverse Effects
Beyond serious adverse events, the systematic review revealed that tramadol was associated with substantially elevated risk of common, non-serious side effects including nausea, dizziness, constipation, and somnolence (excessive sleepiness). These effects, while not acutely life-threatening, significantly impact patients' quality of life and functional capacity. Nausea and vomiting can interfere with nutritional intake and medications timing. Dizziness increases fall risk, particularly dangerous in older adults. Constipation—an extremely common opioid side effect—can become severe and contribute to serious complications including bowel obstruction.[1]
Additional side effects reported with tramadol include fatigue, dry mouth, and insomnia, creating a paradoxical situation where the medication causes both excessive sedation and sleep disturbance. These effects frequently lead to medication discontinuation despite persistent pain, representing treatment failure.[1]
Psychological and Neurological Complications
Beyond gastrointestinal and cardiovascular effects, tramadol has been associated with serious psychological complications including manic episodes, hypomania, serotonin syndrome, psychosis, and cognitive impairment, with risk factors including age, pre-existing psychiatric conditions, polydrug use, and prolonged tramadol exposure. The serotonin syndrome risk is particularly important—a potentially life-threatening condition characterized by muscular rigidity, elevated body temperature, altered mental status, and autonomic instability that can develop when tramadol is combined with other serotonergic medications including certain antidepressants.[5]
Seizures represent another serious neurological risk with tramadol use, particularly at higher doses or in patients with predisposing factors. The mechanism involves both opioid effects and the medication's monoamine reuptake inhibition. Additionally, tramadol's variable metabolism through the cytochrome P450 2D6 enzyme creates unpredictable individual responses—patients designated as "poor metabolizers" of this enzyme may experience inadequate pain relief, while "ultra-rapid metabolizers" face elevated toxicity risk.[2]

Methodological Limitations: Are the Harms Understated?
Bias Risk and Implications for Interpretation
Importantly, the researchers acknowledged that many outcomes were at high risk of bias, with all but two of the included trials rated as having high risk of bias. Rather than undermining the findings, this limitation likely means the harms of tramadol are substantially understated while its benefits are overstated. Bias risk typically occurs through mechanisms including inadequate blinding, selective outcome reporting, and loss to follow-up bias that preferentially affects participants experiencing side effects.[1]
The authors specifically note that given these high-risk-of-bias findings, the actual clinical benefits of tramadol are likely even smaller than the already minimal 0.93-point reduction observed, while actual harms may be substantially larger than detected. This asymmetry is critical: when bias favors overstatement of benefits and understatement of harms, the true benefit-to-harm ratio is even worse than what the analysis indicates.[1]
The Global Opioid Crisis: Context for Tramadol's Role
Staggering Mortality and Morbidity Burden
The opioid crisis represents one of the most devastating public health emergencies of the modern era, with approximately 60 million individuals worldwide experiencing the addictive effects of opioids. The mortality toll is incomprehensible: in 2019, approximately 600,000 deaths occurred related to drug use, with nearly 80% of these fatalities associated with opioids and approximately 25% resulting specifically from opioid overdose. These numbers represent genuine human tragedy—individuals, families, and communities destroyed by addiction.[1]
In the United States specifically, opioid-related overdose deaths have escalated dramatically, increasing from 49,860 in 2019 to 81,806 in 2022—a 64% increase in just three years. This acceleration reflects both the increased potency and prevalence of synthetic opioids (particularly fentanyl) and the persistent overprescribing of opioids for chronic pain despite mounting evidence of limited efficacy and substantial harm. More recent provisional CDC data indicate that nearly 87,000 drug overdose deaths occurred during the 12-month period ending September 2024, with synthetic opioids now involved in an estimated 87% of opioid deaths.[6][1]
What Does a State of Emergency Mean for the Opioid Epidemic
Escalating Prescriptions Despite Inadequate Evidence
Although tramadol prescriptions continue to rise in the United States and internationally, the scientific evidence base does not support this escalation. The 2025 BMJ systematic review is, to the authors' knowledge, the first comprehensive evaluation of tramadol's efficacy and safety across diverse chronic pain conditions. This represents a shocking gap: a medication accounting for millions of prescriptions annually lacked a robust systematic assessment of its true benefit-to-harm ratio until 2025.[3]
The beliefs driving tramadol's widespread adoption—that it represents a "safer" opioid less likely to cause addiction—appear unsupported by scientific evidence. Research demonstrates that tramadol carries comparable or elevated risks of transition to chronic opioid use compared to other short-acting opioids. Additionally, while tramadol may have a different pharmacological profile than conventional opioids, this difference does not translate into meaningful clinical advantages regarding safety or efficacy.[3]
Vulnerable Populations at Heightened Risk
Elderly Patients and Polypharmacy
Older adults face particular vulnerability to tramadol's adverse effects, including heightened risks of falls from dizziness and cognitive impairment, along with increased susceptibility to psychological complications including hypomania and psychosis. Elderly patients frequently take multiple medications for comorbid conditions, substantially increasing the risk of harmful drug interactions. Tramadol's serotonergic effects create dangerous interaction potential with antidepressants and other serotonergic agents commonly prescribed to older adults.[5]
Patients with Psychiatric Histories
Individuals with pre-existing psychiatric conditions face substantially elevated risk of tramadol-induced psychological complications including mood disorders, psychosis, and suicidal ideation. For patients already vulnerable to mental health challenges, tramadol introduces additional risk rather than providing benefit. The medication's effects on mood regulation and behavior are poorly characterized, and screening protocols to identify high-risk individuals are inadequate.[5]
Chronic Pain Management: Alternative Approaches
Non-Opioid Pharmacological Options
For patients with chronic pain, multiple evidence-based alternatives to opioids exist and deserve preferential consideration. Non-steroidal anti-inflammatory drugs (NSAIDs) including ibuprofen and naproxen remain appropriate for inflammatory pain conditions, though their use requires caution in patients with cardiovascular disease, kidney disease, or gastrointestinal ulcer history. Acetaminophen serves as a first-line analgesic for mild-to-moderate pain, though maximum daily doses must be respected to avoid hepatotoxicity.[7]
Antidepressant medications, particularly selective serotonin-norepinephrine reuptake inhibitors (SNRIs) such as duloxetine and tricyclic antidepressants (TCAs), demonstrate efficacy for neuropathic pain and have been recommended as first-line treatments by major pain management guidelines. Gabapentin and pregabalin (Lyrica), which modulate calcium channels, effectively treat neuropathic pain. Topical agents including capsaicin creams and liposomal lidocaine patches provide localized pain relief without systemic effects.[7]
Non-Pharmacological Pain Management Strategies
Evidence-based non-pharmacological approaches represent equally important components of comprehensive pain management. Physical therapy and exercise programs, when appropriately tailored to individual capabilities, reduce pain and improve functional capacity by strengthening supporting musculature and improving mobility. Cognitive-behavioral therapy addresses the psychological components of chronic pain, including catastrophizing, fear-avoidance, and depression.[8]
Additional evidence-based approaches include mindfulness-based stress reduction, acceptance and commitment therapy, acupuncture, and multimodal interventions combining physical, psychological, and pharmacological approaches. Neuromodulation therapies including transcutaneous electrical nerve stimulation (TENS) and emerging technologies like transcranial focused ultrasound show promise for pain management without systemic medication effects.[8]

Clinical Recommendations and Policy Implications
Based on the 2025 BMJ analysis, researchers and medical organizations should prioritize substantially reducing tramadol prescribing for chronic pain management. Rather than tramadol serving as a default pain medication, its use should be reserved—if considered at all—for carefully selected patients where alternative options have proven inadequate and where extensive shared decision-making with detailed discussion of risks and alternatives has occurred.[1]
Healthcare providers should implement systematic deprescribing protocols to transition current tramadol users to safer, evidence-based alternatives. These transitions must occur carefully and gradually to avoid withdrawal phenomena, with appropriate monitoring and support.[1]
The opioid crisis demands comprehensive policy responses extending beyond any single medication. Public health authorities should implement evidence-based strategies including:[1]
· Stricter prescription oversight mechanisms with mandatory patient education regarding opioid addiction risks and non-opioid alternatives
· Prescription drug monitoring programs (PDMPs) to identify and prevent diversion and misuse
· Insurance and formulary restrictions limiting opioid coverage and requiring documentation of attempted non-opioid therapies
· Healthcare provider education emphasizing evidence-based pain management and the limitations of opioid therapy
· Addiction treatment expansion ensuring access to evidence-based treatments including medication-assisted therapy
· Harm reduction strategies including opioid antagonist distribution and supervised consumption sites
Patient Education and Shared Decision-Making
Patients receiving pain management should have access to comprehensive, unbiased information regarding available treatment options, their evidence base, and potential risks and benefits. Healthcare providers must engage in genuine shared decision-making rather than simply prescribing medications by default.[1]
What Patients Should Know: Key Takeaways
Tramadol Is Not a "Safe" Opioid Alternative
The evidence is clear: tramadol does not represent a safer opioid option. While its pharmacological profile differs from conventional opioids, this difference does not translate into meaningful clinical safety advantages. In fact, its dual mechanisms of action create additional risks for serotonin syndrome and other complications not seen with traditional opioids.
Pain Relief Benefits Are Minimal
A reduction of less than one point on a pain severity scale is not clinically meaningful. Most patients would not perceive this degree of improvement in their daily pain experience. If tramadol is under consideration, patients should ask their physicians: "Is there strong evidence this medication will substantially improve my pain?"
The Risk-Benefit Ratio Is Unfavorable
The documented risks—including serious cardiac events occurring in approximately 2% of users, psychological complications, seizures, and numerous common side effects—substantially outweigh the minimal pain relief benefits. This unfavorable ratio supports prioritizing other approaches.
Multiple well-tested, evidence-based alternatives exist for virtually every chronic pain condition. Patients should work with healthcare providers to explore these options before considering tramadol or other opioids.
Conclusion: Toward Evidence-Based Pain Management
The 2025 systematic review published in BMJ Evidence-Based Medicine represents a watershed moment in pain management evidence. For years, tramadol has been prescribed to millions of patients based on the misconception that it represents a "safer" opioid while providing meaningful pain relief—neither claim is supported by rigorous scientific evidence. The comprehensive analysis of 19 randomized trials involving 6,506 participants definitively demonstrates that tramadol's pain-relieving effects are minimal—below clinically meaningful thresholds—while its serious adverse effects including cardiac events occur with concerning frequency.[1]
Given that approximately 87,000 Americans died from drug overdoses in the 12-month period ending September 2024, with synthetic opioids involved in 87% of deaths, the persistence of inadequately effective opioid medications like tramadol represents a genuine public health threat. Each prescriber who selects tramadol as an analgesic choice contributes incrementally to broader opioid normalization and potential downstream harm.[6]
The path forward is clear: tramadol's use should be substantially minimized in favor of safer, evidence-based alternatives including non-pharmacological pain management, non-opioid medications with superior efficacy-safety profiles, and comprehensive multimodal approaches addressing the biological, psychological, and social dimensions of chronic pain. For patients currently taking tramadol, conversations with healthcare providers about transition strategies to alternative therapies should be initiated.[1]
The scientific evidence is unequivocal: when tramadol's limited benefits are weighed against its substantial risks, the balance tips decisively toward harm. Healthcare systems, providers, and patients can do better. By embracing evidence-based pain management approaches and reducing reliance on inadequately effective opioids like tramadol, we move toward more humane, effective, and safer treatment of chronic pain while contributing meaningfully to efforts to address the broader opioid crisis devastating communities globally.
