Short answer
Yes, kratom overdose is possible.
The clearest safety points:
- Single-substance kratom leaf overdose appears less common than polysubstance overdose.
- Concentrated 7-OH products should be treated as higher-risk opioid-like products.
- Many kratom-associated deaths involve more than one substance.
- Severe sedation, slowed breathing, seizures, confusion, and loss of consciousness should be treated as emergencies.
CDC poison-center data from 2015 through 2025 reported 233 kratom-associated deaths, and 79% involved multiple substances. Opioids, benzodiazepines, stimulants, and ethanol were commonly reported among fatal cases.
Why it differs
Why kratom overdose can look different from classical opioid overdose.
Classical opioids such as heroin, fentanyl, morphine, and oxycodone can cause fatal respiratory depression by strongly activating mu-opioid receptors.
Kratom is more complicated. Mitragynine and 7-OH act at opioid receptors, but kratom also has non-opioid activity. Preclinical data suggest that some kratom alkaloids may differ from classical opioids in receptor signaling. That may help explain why respiratory depression is less predictable with natural kratom leaf than with classical full-agonist opioids.
But this should not be simplified into: kratom does not cause respiratory depression. That is too strong.
A safer statement is: respiratory depression appears less predictable with kratom leaf than with classical full-agonist opioids, but sedation, respiratory effects, seizures, and deaths have been reported, especially with concentrated products, 7-OH products, high doses, and sedating combinations.
7-OH
7-OH products are higher risk.
7-hydroxymitragynine, or 7-OH, occurs naturally in trace amounts in kratom. The current public-health concern is not mainly natural trace 7-OH in kratom leaf. It is products with added or enhanced 7-OH.
These products may be sold as:
- Tablets.
- Shots.
- Drinks.
- Gummies.
- High-potency extracts.
- Products labeled as kratom alternatives or kratom extracts.
FDA has warned consumers to avoid products containing added or enhanced 7-OH because they can cause serious harm, including addiction and withdrawal. These products should not be treated as equivalent to occasional kratom leaf tea or powder.
Symptoms
Symptoms of possible kratom or 7-OH overdose.
Possible overdose or toxicity symptoms include:
- Excessive sedation.
- Slow, shallow, or irregular breathing.
- Blue or gray lips.
- Confusion.
- Loss of consciousness.
- Severe vomiting.
- Agitation or disorientation.
- Fast heart rate or palpitations.
- High blood pressure.
- Seizure.
- Chest pain.
Because kratom can produce mixed stimulant-like and opioid-like effects, toxicity does not always look like a classic opioid overdose. Some cases look more sedating. Some look more agitated or stimulant-like. Either pattern can be serious.
In an emergency
What to do.
If someone is very sedated, confused, difficult to wake, breathing slowly, having a seizure, or has blue or gray lips:
- Call 911 immediately.
- Give naloxone if available.
- Start rescue breathing or CPR if trained and needed.
- Keep the person on their side if vomiting and breathing.
- Bring the product package, label, bottle, or a photograph to the hospital.
Naloxone is reasonable to try because kratom and 7-OH involve opioid receptors. The response may be partial or uncertain, especially if other substances are involved, but naloxone is unlikely to harm someone in a suspected overdose.
Higher-risk groups
Who is at higher risk?
Higher-risk situations include:
- Daily 7-OH use.
- High-dose kratom extracts.
- First-time users taking high doses.
- Mixing with alcohol.
- Mixing with benzodiazepines such as alprazolam, clonazepam, lorazepam, or diazepam.
- Mixing with opioids.
- Mixing with gabapentin or pregabalin.
- Mixing with sleep medications or muscle relaxers.
- Seizure history.
- Liver disease.
- Heart disease.
- Use of products with unclear labeling or suspected adulteration.
The most important practical safety rule is to avoid combining kratom or 7-OH with sedating substances.
Combinations
Kratom plus alcohol, benzodiazepines, gabapentin, or opioids.
This is the highest-yield safety issue.
Kratom or 7-OH combined with other sedatives can increase the risk of:
- Over-sedation.
- Falls.
- Vomiting while sedated.
- Slowed breathing.
- Blackouts.
- Emergency department visits.
- Death.
Risk is especially concerning with:
- Alcohol.
- Xanax, Klonopin, Ativan, Valium, and other benzodiazepines.
- Gabapentin or pregabalin.
- Prescription opioids.
- Fentanyl or heroin.
- Sleep medications.
- Muscle relaxers.
If you are taking buprenorphine and still using kratom or 7-OH, tell your prescriber. This is especially important if you also use alcohol, benzodiazepines, gabapentin, pregabalin, or sleep medications.
In the news
Are kratom deaths real?
Yes. Deaths involving kratom have been reported.
The more careful statement is that most reported kratom-associated deaths involve multiple substances, and the role of kratom can vary from case to case. In some cases, kratom may be one contributor among several. In others, concentrated 7-OH products or very high-potency products may be more central. In a smaller number of reports, kratom appears to be the only identified substance, though post-mortem testing and product analysis are not always complete.
This means both extreme statements are wrong:
- Kratom is completely safe and cannot cause overdose.
- Kratom is identical to fentanyl or heroin.
The defensible middle is: kratom-associated overdose and death are real, risk is much higher with polysubstance use and concentrated 7-OH products, and people should treat severe sedation or breathing problems as emergencies.
Worried about yourself
What to do if you are worried about your own use.
Get help if:
- You are escalating doses.
- You wake up in withdrawal.
- You cannot get through the day without dosing.
- You are using 7-OH daily.
- You are mixing kratom with sedatives.
- You have had blackouts, falls, confusion, or breathing scares.
- You have tried to stop and could not.
Treatment does not have to mean inpatient rehab. Many people can be treated outpatient with tapering, supportive care, or medication treatment when appropriate.

Medical note
Kratom and 7-OH products vary widely in strength, purity, labeling accuracy, and legal status. This page is educational and does not replace medical care. Call 911 for severe sedation, slowed or irregular breathing, blue or gray lips, seizure, chest pain, loss of consciousness, or inability to wake the person.
