Kratom overdose: Signs, risks, and what to do

If someone may be overdosing right now, call 911 immediately. Signs can include slow or stopped breathing, blue or gray lips or fingertips, being unable to wake up, or having a seizure. Don’t wait to read the rest of this page before getting emergency help. See “What to do if you think someone is overdosing” for additional information once help is on the way.

If you’re asking about the possibility of a kratom overdose, you’re already taking it seriously, and that matters. Kratom is often sold and talked about as a natural supplement, so it’s easy to assume it can’t cause a real medical emergency. That assumption isn’t safe, especially with how much stronger some 7-OH products on the market have become.

Can you overdose on kratom?

Yes. Kratom and 7-OH can both cause an overdose, especially at high doses, with concentrated 7-OH products, or when either is combined with other substances. It doesn’t always look like what most people picture when they think of an overdose, but it can be just as dangerous.

Warning signs of a kratom or 7-OH overdose

Symptoms show up differently depending on which system they disturb. Here’s what to watch for, grouped by what’s affected:

• Stomach: nausea, vomiting
• Heart: a fast or irregular heartbeat, high blood pressure
• Brain and behavior: drowsiness, confusion, agitation, seizures, and what some people call “the wobbles”: a wave of dizziness and involuntary eye movement
• Breathing (the most dangerous): slow or shallow breathing, trouble staying awake, unresponsiveness

Rare but severe cases have also involved muscle breakdown, temporary hearing loss, and heart failure after heavy use.

Call 911 immediately if you see any of these:

• Slow or stopped breathing
• Blue or gray lips or fingertips
• They can’t be woken up
• They’re having a seizure

Why concentrated 7-OH products are more dangerous than leaf kratom

Natural leaf kratom contains only trace amounts of 7-OH. But some commercial products (gummies, shots, tablets) have been tested at concentrations up to around 40%.

At that level, 7-OH acts much more like a potent opioid and raises the risk of dangerous breathing suppression. You can read more about what that does to the brain and body in our article discussing 7-OH effects.

We want to be upfront that much of this evidence comes from several published case reports, not from large studies. We’re still learning exactly how much more dangerous concentrated 7-OH is compared with leaf kratom.

What we’ve heard from our own patients

This research lines up with what we see in our own patients. People coming off 7-OH regularly describe a withdrawal that feels as bad as, or worse than, withdrawal from stronger prescription opioids. 

The symptoms that come up most often are severe trouble sleeping, restlessness, heavy sweating, nausea, diarrhea, body aches, intense cravings, and anxiety. Many tell us they tried to stop cold turkey and couldn’t get through it on their own, which is what finally brought them in for care.

Here’s another pattern we see: someone starts on a prescription opioid, turns to 7-OH hoping it will ease the withdrawal from that opioid, and ends up dependent on 7-OH instead.

To be direct: kratom and 7-OH don’t safely treat opioid withdrawal. Using one to get off the other usually just trades one dependence for another. 

And with several states now banning concentrated 7-OH outright and a federal scheduling action expected soon, people who relied on it are starting to lose access. If you’re unsure about the legality where you live, check out our article on current kratom and 7-OH laws.

What to do if you think someone is overdosing

This is the most important part of this article. If you see any of the warning signs, work through these four steps.

Step 1: Call 911 right away. 

Do this first for any red-line symptom: slow or stopped breathing, unresponsiveness, blue or gray lips, or a seizure. Most states have Good Samaritan laws that protect the person who calls for help, even if drugs were involved.

Step 2: Give naloxone (Narcan) if you have it. 

Kratom and 7-OH affect the body the same way opioids do, so naloxone can reverse an overdose from either one just as effectively. Give one dose, wait 2 to 3 minutes, and give a second dose if breathing hasn’t improved. Naloxone is available at most pharmacies, often without a prescription.

Step 3: Keep them breathing and on their side. 

If they’re breathing but not fully awake, roll them onto their side (the recovery position) so they don’t choke if they vomit. Try to keep them awake and breathing until help arrives.

Step 4: Stay with them and tell responders what was taken. 

Don’t leave until help arrives. Tell paramedics exactly what was taken if you know, including the product name and any other items involved, and keep the packaging so they can see it.

A word on “rebound”: Naloxone only works for about 30 to 90 minutes, and kratom or 7-OH can stay active in the body longer than that. That means someone can seem okay, then stop breathing again once the naloxone wears off. This is called rebound. This is why calling 911 still matters even after someone wakes up, and why they need to be watched closely and may need another dose.

When kratom overdose is more likely: dangerous drug combinations

Most kratom-related deaths involve more than one substance. In a CDC review of kratom-positive overdose deaths, fentanyl or similar drugs were present in about 65% of cases, benzodiazepines in about 22%, and alcohol in about 13%.

Combining kratom or 7-OH with opioids, benzodiazepines, or alcohol sharply raises the risk of dangerous breathing suppression. Each of these slows breathing in similar ways, and the effects compound.

Who is at the highest risk for a kratom overdose?

Anyone can have a bad reaction, but the risk is higher for people who are: 

• Using concentrated 7-OH products instead of plain leaf kratom
• Combining kratom or 7-OH with opioids, benzodiazepines, or alcohol
• New to opioids, with little or no tolerance built up
• Trying to manage opioid withdrawal with kratom or 7-OH on their own (as noted above, this tends to create a new dependence rather than solve the original one)

Is a kratom overdose fatal?

It can be, though deaths from kratom alone are less common than deaths involving stronger opioids like fentanyl or heroin. One CDC report identified 91 kratom-involved overdose deaths over an 18-month period, with kratom as the only substance detected in seven of them. Poison control centers have also logged a rising number of kratom-related calls over the past decade.

In one recent case, a person went into cardiac arrest after using 7-OH and was revived with naloxone. It’s a real example, and a reminder that these overdoses, while serious, can be survivable with fast action.

Getting help after a kratom or 7-OH overdose

An overdose usually means kratom or 7-OH use has gone further than someone can manage alone. That’s a sign of kratom use disorder (KUD), not a personal failure in any way. This is far more common than it might feel in the moment.

Suboxone® (buprenorphine-naloxone), the same medication used to treat opioid use disorder, is also used to treat kratom and 7-OH dependence. QuickMD’s licensed doctors can help you start treatment or get a Suboxone prescription online in 40+ states, often the same day.
