Tramadol is a synthetic opioid used to treat moderate to severe chronic pain in adults. It is a widely used medication due to its lower potential for abuse and fewer side effects compared to other opioid analgesics. However, tramadol has been associated with a rare side effect known as negative myoclonus (NM) or involuntary muscle twitching. This side effect typically presents as sudden, jerky movements of the arms and neck, which can be distressing and disruptive to patients. While the incidence of tramadol-induced NM is considered rare, it is important for clinicians and patients to be aware of this potential adverse effect, especially as it can be completely resolved through discontinuation of the medication.

What You'll Learn
Tramadol is a widely used synthetic opioid
Tramadol is a centrally-acting opioid agonist and SNRI (serotonin/norepinephrine reuptake inhibitor) that is structurally related to codeine and morphine. It is approved by the US Food and Drug Administration (FDA) as a pain relief medication for moderate to severe pain. It selectively binds to various opiate receptors in the central nervous system (CNS) due to its opioid nature. The liver enzyme CYP2D6 converts tramadol to its active metabolite, M1, which has a stronger affinity for the mu receptor than the inactive form.
The maximum recommended daily dose of tramadol is 400 mg. However, it is important to note that tramadol has a wide variability in pharmacokinetic properties between patients due to polymorphisms within the gene for CYP2D6, which affect its enzymatic activity. Some individuals may be "extensive metabolizers" with normal CYP2D6 function, while others may be "poor metabolizers" with reduced or non-functioning enzyme activity.
While tramadol is a useful medication for pain management, it is not without its side effects. Common side effects include hypertonia, arthralgia, back pain, limb pain, neck pain, muscle cramps, muscle spasms, joint stiffness, muscle twitching, and myalgia. Less common side effects include joint swelling, joint sprains, and muscle injuries. Additionally, there have been reports of tramadol causing negative myoclonus (NM), which is a shock-like jerky involuntary movement caused by a sudden, brief interruption of tonic muscle contraction. In some cases, discontinuing tramadol and administering alternative medications have been shown to resolve the symptoms of NM.
It is important for patients to consult with their doctors before using tramadol, especially if they intend to use it in conjunction with other medications that affect the central nervous system (CNS). The use of alcohol or other CNS-affecting medications with tramadol may worsen side effects such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble sleeping.

Negative myoclonus (NM) is a side effect
Tramadol is a synthetic opioid medication used to treat moderate to moderately severe chronic pain in adults, including pain after surgery. It is a widely used analgesic for acute and chronic pain because it is less likely to be abused and has fewer side effects than other opioid analgesics. However, it can still cause side effects such as NM.
A French epidemiologic study on the incidence of drug-induced myoclonus reported that 12% of cases were caused by opioid agents, with 25% of those being attributed to tramadol. The incidence of tramadol-induced NM is possibly underestimated, considering that many patients experience mild and transient symptoms after taking the medication.
In one case, a 55-year-old man presented with NM in both arms and his neck after taking a therapeutic dose of tramadol for five days. His symptoms completely resolved after discontinuing tramadol and administering oral clonazepam. This case suggests that tramadol can cause NM in patients without a history of seizures or metabolic disorders, even within its therapeutic dose range.
It is important to note that the use of alcohol or other central nervous system (CNS)-affecting medications with tramadol may worsen side effects such as NM. Therefore, patients should consult their doctors before combining tramadol with other substances.

Serotonin syndrome is a risk
Tramadol is an opioid medication used to treat moderate to moderately severe chronic pain in adults. It is a widely used synthetic opioid used for acute and chronic pain control. It is also a weak mu-opioid receptor agonist and inhibits the reuptake of serotonin at the synaptic cleft, increasing serotonin levels.
Serotonin syndrome is a condition caused by an excess of serotonin in the body. It is a rare but serious side effect of tramadol that can be life-threatening. When taken alone or with other medications that affect serotonin levels, tramadol can cause serotonin syndrome. The risk of developing serotonin syndrome may be higher if you are also taking other medications that affect serotonin levels.
The symptoms of serotonin syndrome include muscle twitching, jerking, spasms, tremors, or other uncontrolled movements. Other symptoms include anxiety, restlessness, a fast heartbeat, fever, sweating, muscle stiffness, loss of coordination, nausea, vomiting, diarrhoea, agitation, hallucinations, shivering, and suicidal thoughts or actions. If you experience any of these symptoms, seek emergency medical help immediately.
Tramadol can also cause negative myoclonus (NM), which is a shock-like jerky involuntary movement caused by a sudden, brief interruption of tonic muscle contraction. NM can occur in patients with epilepsy, metabolic encephalopathy, drug toxicity, or brain lesions. However, there have been reported cases of tramadol-induced NM in patients without a history of seizures or metabolic disorders. Discontinuation of tramadol and oral administration of clonazepam have been shown to resolve NM symptoms.

Tramadol may cause seizures
Tramadol is a synthetic opioid commonly used to treat acute and chronic pain. It is often chosen over other opioids because it has a lower risk of addiction and respiratory depression. However, it is important to note that tramadol may cause seizures in some individuals.
Tramadol-induced seizures typically occur within the first 4-6 hours after excessive ingestion of the drug. They usually present as a single generalized tonic-clonic episode. The prevalence of tramadol-related seizures in population-based studies ranges from 0.15% to 0.86%. Between 1997 and 2017, there were 2019 tramadol-related seizure cases reported to the FDA, with 145 resulting in death.
Several factors can increase the risk of tramadol-induced seizures. These include high doses, co-prescribed medicines, and a history of epilepsy. In addition, the concomitant use of selective serotonin reuptake inhibitors, tricyclic antidepressants, and antipsychotics can lower the seizure threshold and increase the probability of seizure occurrence.
It is important for prescribers to be aware of these risks and consider a patient's medical history and current medications before prescribing tramadol. If seizures occur, they can be effectively treated by administering benzodiazepines, providing supportive care, and discontinuing tramadol.
Tramadol has also been associated with a rare side effect known as negative myoclonus (NM), which is a shock-like jerky involuntary movement caused by a sudden, brief interruption of tonic muscle contraction. NM can occur in patients with epilepsy, metabolic encephalopathy, drug toxicity, or brain lesions. In some cases, patients have experienced NM after taking therapeutic doses of tramadol, even without a history of seizures or metabolic disorders.

It is habit-forming
Tramadol is an opioid medication used to treat moderate to moderately severe chronic pain in adults, including pain after surgery. It is less likely to be abused compared to other opioid analgesics. However, when tramadol is used for a long time, it may become habit-forming, leading to mental or physical dependence. Mental dependence or addiction is not likely to occur when narcotics are used for pain relief. On the other hand, physical dependence may result in withdrawal side effects if the treatment is stopped abruptly. Nevertheless, severe withdrawal symptoms can typically be prevented by gradually reducing the dosage over time before completely discontinuing the medication.
The risk of habit formation with tramadol use underscores the importance of taking this medication only as prescribed by a healthcare professional. It is crucial to follow the recommended dosage and duration of treatment to mitigate the risk of developing dependence. Moreover, individuals taking tramadol should be vigilant about potential signs of dependence and seek medical advice if they experience any symptoms indicative of habit formation. This proactive approach can help in early detection and facilitate timely interventions to address the issue effectively.
The potential for habit formation associated with tramadol underscores the need for careful patient monitoring and management. Healthcare providers play a pivotal role in assessing each patient's risk factors for developing dependence and individualizing treatment plans accordingly. This includes considering alternative treatment options or incorporating adjunct therapies to mitigate the risk of habit formation. Close monitoring during treatment helps identify early signs of dependence, enabling prompt adjustments to the treatment regimen if necessary.
While tramadol is known for its analgesic properties, it is not without risks, and habit formation is a significant concern. The potential for misuse, overdose, and even death associated with this medication cannot be overstated. Therefore, it is imperative for individuals taking tramadol to be aware of the signs of dependence and to seek medical advice if they experience any symptoms indicative of habit formation. Additionally, storing and handling tramadol responsibly is crucial to prevent access by unauthorized individuals, particularly children, who are more susceptible to adverse effects.
In conclusion, while tramadol is an effective medication for managing pain, its potential for habit formation warrants caution. It is crucial to recognize the signs of dependence and to seek appropriate medical advice if any symptoms arise. By taking a proactive and informed approach, individuals can benefit from the therapeutic effects of tramadol while mitigating the risk of developing mental or physical dependence associated with its long-term use.
