Tramadol is not safe for everyone. Several groups of people face serious, sometimes life-threatening risks from this pain medication, and for some, it is explicitly contraindicated. Children under 12, people with certain genetic profiles, those taking common antidepressants, and individuals with a history of addiction are among those who should avoid it entirely or use it only with extreme caution.
Children Under 12 and Teens After Tonsil Surgery
The FDA has placed its strongest warning, a Contraindication, against using tramadol in children younger than 12 for any type of pain. The risk of slowed or dangerously difficult breathing is too high in young children, and deaths have occurred. All tramadol-containing products are approved only for use in adults.
A separate contraindication applies to anyone under 18 who needs pain relief after surgery to remove tonsils or adenoids. These children already face swelling in the airway, and tramadol’s respiratory effects can compound that risk. If your child is scheduled for one of these procedures, tramadol should not be part of the pain management plan.
People Who Are Ultrarapid Metabolizers
Your body converts tramadol into a much more potent form using a liver enzyme called CYP2D6. Most people do this at a normal pace, but roughly 1 to 10% of the population processes the drug far faster than intended. These “ultrarapid metabolizers” end up with dangerously high levels of the active form in their blood, even at standard doses. The FDA label states plainly that ultrarapid metabolizers should not use tramadol because of the risk of life-threatening respiratory depression and overdose symptoms like extreme sleepiness, confusion, and shallow breathing.
The prevalence of this genetic trait varies by background. It’s estimated at 1 to 10% among White populations, 3 to 4% among Black Americans, 1 to 2% among East Asians, and potentially higher than 10% in some groups, including people of Northern African, Middle Eastern, Oceanian, Ashkenazi Jewish, or Puerto Rican descent. Pharmacogenomic testing can identify this trait before a prescription is written, though it isn’t routinely ordered.
People Taking Antidepressants
If you take an SSRI like citalopram or sertraline, or an SNRI like venlafaxine or duloxetine, combining these medications with tramadol raises the risk of a condition called serotonin syndrome. This happens when too much serotonin accumulates in the nervous system, causing a combination of muscle twitching, agitation, rapid heart rate, sweating, and confusion. In severe cases it can be fatal.
Among opioid painkillers, tramadol appears to be the most frequent culprit for serotonin syndrome when paired with antidepressants. Published case reports involving tramadol far outnumber those for other opioids. Since tens of millions of people take SSRIs or SNRIs, this interaction is one of the most practically important reasons someone might need a different pain medication. Many prescribers underestimate this risk, so it’s worth mentioning your antidepressant specifically if tramadol is being considered.
People With a History of Seizures
Tramadol lowers the seizure threshold, meaning it makes seizures more likely to occur. This is unusual among opioid painkillers and makes tramadol a poor choice for anyone with epilepsy, a history of seizures, or conditions that predispose them to seizures, such as a prior head injury. The risk increases further when tramadol is combined with other medications that also lower seizure threshold, including many of the antidepressants mentioned above.
People With Breathing Disorders
Like all opioids, tramadol can slow breathing. For most healthy adults this effect is mild, but for people with compromised respiratory function it can become dangerous. The European Medicines Agency specifically restricts tramadol use in patients with obstructive sleep apnea or other conditions that impair breathing. People with severe COPD, asthma that is poorly controlled, or any condition that already limits how much oxygen they take in should approach tramadol with significant caution.
People Using Alcohol, Benzodiazepines, or Other Sedatives
Combining tramadol with anything else that depresses the central nervous system creates a compounding effect on breathing and consciousness. The FDA requires its strongest boxed warning on opioids about this combination, noting that mixing them with benzodiazepines (commonly prescribed for anxiety, insomnia, and seizures), other sedating medications, or alcohol can result in extreme sleepiness, slowed breathing, coma, and death. This applies to recreational substances as well, not just prescriptions.
If you regularly drink alcohol, even moderately, or take medications like lorazepam, alprazolam, or sleep aids, tramadol significantly raises your risk of a serious adverse event.
People With Addiction History
The FDA label for tramadol states directly: do not prescribe it for patients who are addiction-prone. People with a personal or family history of substance abuse, including alcohol addiction, face a higher risk of developing dependence on tramadol. The same applies to people with major depression or other mental health conditions that increase vulnerability to misuse.
Tramadol is a Schedule IV controlled substance, and while it’s considered lower risk than stronger opioids, it still activates opioid receptors and can produce dependence, tolerance, and withdrawal. For people with a history of substance use disorder, alternative pain management strategies are generally safer.
People With Severe Kidney or Liver Disease
Tramadol is processed through both the liver and kidneys. When either organ is significantly impaired, the drug and its active byproduct build up in the body, increasing the risk of side effects and overdose. Patients with advanced liver cirrhosis require substantial dose reductions. The same applies to people with severe kidney impairment, defined as a creatinine clearance below 30 mL/min, where the dosing interval must be lengthened and the maximum daily dose is cut in half. For people at the more severe end of organ impairment, tramadol may not be appropriate at all.
Pregnant and Breastfeeding Women
Tramadol use during pregnancy, particularly daily use at higher doses, has been linked to neonatal opioid withdrawal syndrome. Babies exposed to tramadol throughout pregnancy have developed symptoms within the first week of life, including irritability, vomiting, stiff muscles, rapid heart rate, tremors, and in some cases seizures.
Tramadol also passes into breast milk. The FDA recommends against using it while breastfeeding because of the risk of serious problems in infants, including excessive sleepiness, difficulty breastfeeding, and breathing problems that could be fatal. This risk is especially pronounced in mothers who happen to be ultrarapid metabolizers, since they produce more of the potent active form that then transfers to the infant.
Older Adults
People over 65 face a distinct set of risks with tramadol. Chronic use in older adults has been associated with increased rates of falls, hip fractures, cardiovascular events, emergency room visits, and hospitalization. Tramadol has also been linked to delirium in older patients, a state of acute confusion that is itself a risk factor for later developing dementia. The sedating and balance-disrupting effects of the drug are more pronounced in aging bodies that metabolize medications more slowly, making even standard doses potentially problematic.
