Dextromethorphan (DXM), a cough suppressant, and kratom, a herbal supplement, impact the brain and body in very different ways.
When used together, they can mask each other's effects, increase mental health risks, and raise the potential for misuse or dependence. Whether this combination is taken intentionally or by accident, it's important to understand how it affects your physical and emotional well-being.
In this article, you'll learn how DXM and kratom work individually, what makes their combination risky, and how to recognize when it might be time to seek support.
Dextromethorphan (DXM) is a common active ingredient found in over-the-counter cough and cold medications. At recommended doses, it effectively suppresses coughing. However, when taken in higher amounts, DXM can produce dissociative and hallucinogenic effects.
In the brain, DXM affects the central nervous system by acting on NMDA (N-methyl-D-aspartate) receptors, which play a role in pain perception, cognition, and mood regulation. By interfering with these receptors, DXM can produce dissociative effects, including altered perception, distorted sensory input, and changes in consciousness.
In the body, DXM is metabolized by liver enzymes—primarily CYP2D6 and CYP3A4. The activity of these enzymes can vary significantly between individuals based on genetics, medications, or other substances in the system. This means that DXM’s effects can be unpredictable, especially when combined with other drugs or supplements that inhibit or compete with these metabolic pathways.
The short-term effects of DXM use can include:
Euphoria
Hallucinations
Impaired motor coordination
Increased heart rate and blood pressure
Nausea and vomiting
Dizziness and confusion
While these effects may seem temporary, even short-term use can lead to dangerous physical and psychological consequences—especially at high doses or when mixed with other substances. What begins as recreational experimentation can quickly escalate into serious health risks.
The long-term effects of DXM use can include:
Memory impairments
Cognitive deficits
Mood disturbances
Risk of addiction
Potential for overdose
Over time, repeated DXM use can cause lasting changes in brain function and emotional health. These long-term effects not only interfere with daily life but can also make recovery more challenging without professional support.
Yes, DXM has the potential for abuse and addiction, especially when used in higher-than-recommended doses. Regular misuse can lead to tolerance, dependence, and withdrawal symptoms.
With prolonged use, the brain may come to rely on DXM to function normally, making it harder to stop without experiencing physical or emotional discomfort. This cycle can deepen the risk of long-term harm and make recovery feel overwhelming without the right support.
Kratom (Mitragyna speciosa) is a tropical tree native to Southeast Asia. Its leaves contain compounds that can have stimulant or sedative effects, depending on the dose. Kratom is often used for pain relief, mood enhancement, and as an alternative to opioids.
Today, kratom is commonly used for pain relief, mood enhancement, and sometimes as an alternative to opioids, though its safety and legality remain subjects of ongoing debate. Despite its natural origins, kratom can still pose significant health risks, especially when used improperly or combined with other substances.
In the brain, kratom’s active compounds, mitragynine and 7-hydroxymitragynine, bind to opioid receptors, producing pain-relieving and euphoric effects at higher doses. At lower doses, the same compounds can act as stimulants, increasing alertness and energy.
In the body, kratom influences several systems, including the digestive, cardiovascular, and nervous systems. It can slow gastrointestinal activity, elevate heart rate, and impact hormone levels, which may contribute to both its perceived benefits and its potential for harmful side effects when misused.
The short-term effects of kratom use can include:
Increased energy and alertness
Euphoria
Analgesia (pain relief)
Nausea and constipation
Dry mouth and loss of appetite
These effects typically begin within minutes of ingestion and can last several hours, depending on the dose and method of use. While some users seek these outcomes for relief or stimulation, they can quickly lead to discomfort or risky patterns of repeated use.
The long-term effects of kratom use can include:
Dependence and withdrawal symptoms
Liver toxicity
Cognitive impairments
Increased risk of seizures
Respiratory depression
Prolonged use may also contribute to tolerance, where larger doses are needed to achieve the same effects, increasing the risk of adverse outcomes. Over time, these physical and neurological effects can severely impact daily functioning and overall health.
Yes, kratom can be addictive. Regular use can lead to tolerance, dependence, and withdrawal symptoms, including irritability, anxiety, and muscle pain.
Although some people use kratom as a substitute for opioids, its impact on the brain’s reward system can still foster compulsive use. Over time, individuals may find it difficult to stop using kratom without experiencing physical or psychological discomfort.
Combining DXM and kratom can be dangerous due to their effects on the central nervous system and metabolism.
Potential risks of mixing DXM and kratom include:
Metabolic Interactions: Kratom inhibits the liver enzymes CYP2D6 and CYP3A4, which are responsible for metabolizing DXM. This can lead to increased levels of DXM in the body, raising the risk of adverse effects and overdose.
Amplified Sedation: Both substances can cause sedation. When taken together, the sedative effects can be amplified, leading to respiratory depression and increased risk of overdose.
Increased Risk of Seizures: Combining substances that affect the nervous system can increase the risk of seizures.
Unpredictable Effects: The combination can lead to unpredictable psychological effects, including confusion, agitation, and paranoia.
Because both drugs influence similar biological pathways, their interaction can intensify each other’s harmful effects in ways that are difficult to anticipate. This makes the combination particularly risky—even for individuals who have used either substance on its own without issue.
If you or someone you care about is frequently combining DXM and kratom—whether to enhance effects, cope with stress, or manage symptoms—it could be a sign of a deeper issue.
Mixing drugs to regulate mood or function often points to an underlying substance use disorder (SUD). Seeking support early can help prevent serious health complications and pave the way toward safer, healthier coping strategies.
If you find yourself relying on DXM, kratom, or a combination of both to cope with daily stress, focus, or emotional challenges, it may be time to seek professional help. Signs that support could be beneficial include:
Feeling unable to cut back or stop using
Using more frequently or in higher doses than intended
Experiencing mental or physical health changes
Neglecting responsibilities at work, school, or home
Using substances to manage anxiety, sleep, or focus
Asking for help isn’t a sign of failure—it’s a step toward a healthier, more stable life. A licensed addiction professional can help you explore your options and start the path to recovery.
Recovering from substance use isn’t just about quitting—it’s about rediscovering balance, rebuilding trust in yourself, and creating a life that no longer relies on drugs to cope. Whether you're facing challenges with DXM, kratom, or both, meaningful change is possible with the right support.
Treatment may include a combination of approaches tailored to your needs:
Medically Supervised Detox: Helps manage withdrawal symptoms safely with the care of healthcare professionals.
Inpatient or Outpatient Treatment: Offers structured support through counseling, group therapy, and education, either in a live-in facility or while living at home.
Individual Therapy: Focuses on addressing emotional patterns, trauma, or mental health concerns that may fuel substance use.
Community and Peer Support: Provides connection through support networks like NA, SMART Recovery, or other recovery groups that foster accountability and shared experiences.
Healing doesn’t happen overnight, but it starts with one decision. You don’t have to face this alone—help is here when you’re ready.
Mixing DXM and kratom might seem manageable in the short term, but the long-term risks can affect everything from your health to your relationships. Understanding how these substances interact—and recognizing the signs of misuse—can be the first step toward lasting change.
If you or someone close to you is using drugs in a way that feels out of control, help is available. With the right support, recovery is not just possible—it’s sustainable.
You deserve a future free from the risks of substance use. And it all starts by reaching out.
