Tramadol provides modest relief for arthritis pain, but the evidence suggests it’s not a great option for most people. In clinical trials for knee osteoarthritis, tramadol reduced pain on a 100-point scale by about 30 points compared to roughly 18 points for a placebo. That’s a real difference, but it’s smaller than what common anti-inflammatory medications achieve, and tramadol comes with a significantly higher rate of side effects. The American College of Rheumatology conditionally recommends against using tramadol for osteoarthritis of the hand, hip, and knee, citing weak evidence of benefit and meaningful potential for harm.
How Tramadol Works for Joint Pain
Tramadol is a centrally acting painkiller with two mechanisms. It binds weakly to opioid receptors in the brain, which dulls pain signals. It also blocks the reabsorption of serotonin and norepinephrine, two brain chemicals involved in mood and pain processing. This dual action is what sets tramadol apart from stronger opioids, and it’s partly why tramadol was once considered a “safer” alternative. That perception has shifted considerably as more data has emerged.
What the Clinical Evidence Shows
A 12-week trial of extended-release tramadol in people with knee osteoarthritis found statistically significant improvements in pain intensity and patients’ overall assessment of their therapy compared to placebo. The pain reduction exceeded what researchers consider the minimum clinically noticeable improvement. So tramadol does work better than a sugar pill.
The problem is how it stacks up against alternatives. A large network meta-analysis published in The BMJ compared opioids (including tramadol) against various anti-inflammatory medications for knee and hip osteoarthritis. Tramadol, at any dose, had only a small effect on pain and physical function. Its probability of reaching a meaningful improvement threshold was 18% or lower. By comparison, effective anti-inflammatory drugs were 1.5 to 1.8 times more potent than the minimum meaningful difference, with much higher probabilities of providing real relief.
The BMJ analysis concluded bluntly: the clinical benefit of opioid treatment, regardless of the specific drug or dose, does not outweigh the harm it causes in osteoarthritis patients.
Side Effects Are a Major Drawback
The most common side effects of tramadol are constipation and drowsiness. Nausea and dizziness also occur frequently. These aren’t just minor annoyances. In the BMJ meta-analysis, about 83% of opioid preparations (including tramadol) carried an increased risk of patients dropping out of studies because of adverse events. For comparison, only 18.5% of oral anti-inflammatory drugs showed the same pattern. Nearly 90% of opioid treatments had an increased risk of causing any adverse event, compared to about 30% of oral anti-inflammatories.
In practical terms, this means a large number of people who start tramadol for arthritis pain will stop taking it because the side effects aren’t worth the modest relief.
Risks for Older Adults
Most people dealing with arthritis are over 65, and that’s exactly the population most vulnerable to tramadol’s downsides. Opioids, including tramadol, increase fall risk through sedation, dizziness, and impaired thinking. Falls are the leading cause of injuries for adults 65 and older, with 30% to 40% of older adults falling each year. Adding a medication that causes drowsiness and lightheadedness to that equation is a serious consideration.
Tramadol’s effect on serotonin and norepinephrine also creates a concern that stronger opioids don’t share. Older adults are more likely to be taking antidepressants or other medications that affect serotonin levels, which raises the risk of a dangerous interaction (more on that below).
Dependency and Withdrawal
Tramadol is classified as a Schedule IV controlled substance by the DEA, meaning it has a recognized potential for abuse and dependence. While that’s a lower schedule than drugs like oxycodone (Schedule II), the risk is real. Tolerance, physical dependence, and addiction have all been documented, and the risk isn’t limited to people with a history of substance use problems.
Stopping tramadol abruptly can trigger two distinct types of withdrawal. About 90% of withdrawal cases involve typical opioid symptoms: flu-like feelings, restlessness, and drug cravings. The remaining 10% experience an atypical withdrawal that can include hallucinations, paranoia, extreme anxiety, panic attacks, and numbness or tingling in the hands and feet. This atypical pattern is unusual among opioids and is linked to tramadol’s effect on serotonin and norepinephrine.
Dangerous Drug Interactions
Because tramadol affects serotonin levels, combining it with other serotonin-boosting medications can trigger serotonin syndrome, a potentially life-threatening condition that causes agitation, rapid heartbeat, high blood pressure, and in severe cases, seizures. Medications that create this risk when paired with tramadol include:
- Antidepressants: SSRIs, tricyclics, venlafaxine, mirtazapine, and MAO inhibitors
- Migraine medications: triptans like sumatriptan and naratriptan
- Other substances: St. John’s wort, lithium, bupropion, and certain Parkinson’s medications
Tramadol is completely contraindicated in anyone taking MAO inhibitors or who has taken them within the past 14 days. Given that many people with chronic arthritis pain also take antidepressants, this interaction is a practical concern, not a theoretical one.
How It Compares to Anti-Inflammatory Options
For most people with osteoarthritis, anti-inflammatory medications outperform tramadol on both pain relief and tolerability. The BMJ network analysis found that effective oral anti-inflammatory drugs produced pain reductions roughly double what tramadol achieved, while causing far fewer dropouts due to side effects. Topical anti-inflammatory creams and gels performed well too, with zero increased risk of adverse events or treatment discontinuation in the analysis.
This doesn’t mean anti-inflammatory drugs are risk-free. Long-term oral use can cause stomach ulcers, kidney problems, and cardiovascular issues, which is partly why tramadol entered the picture as an alternative in the first place. But the data now suggests that for osteoarthritis specifically, tramadol’s modest benefits don’t justify its burden of side effects, dependency risk, and drug interactions.
When Tramadol Might Still Be Considered
Tramadol generally enters the conversation only after first-line treatments have failed or aren’t safe for a particular person. Someone who can’t tolerate anti-inflammatory medications due to stomach problems, kidney disease, or cardiovascular risk might be offered tramadol as a short-term option. Even then, the ACR’s conditional recommendation against it reflects the view that other approaches, including physical therapy, weight management, joint injections, and topical treatments, should be prioritized.
If tramadol is prescribed, the typical approach involves starting at a low dose and increasing gradually over several days to reduce side effects. The maximum is 400 mg per day, taken in divided doses every four to six hours. Most prescribers aim to keep the dose as low as possible and the duration as short as practical.
