Recognizing a 7-OH Overdose and What to Do

If someone who has taken 7-OH is breathing slowly or has stopped breathing, is limp, or cannot be woken, call 911 now and give naloxone if it is on hand. 7-OH is a mu-opioid receptor agonist, so the respiratory depression it causes is opioid respiratory depression and is naloxone-reversible, which is the single fact that decides what you do in the next five minutes.

What a 7-OH overdose looks like

A 7-OH overdose presents as an opioid overdose, because that is the receptor it acts on. The picture is usually quiet. Someone who has been nodding off becomes someone you cannot wake, and breathing slows first. Split what you see into two tiers.

Signs that mean call 911 now

• Breathing that is slow, shallow, irregular, or has stopped.
• Choking, gurgling, or a snoring sound from someone who does not usually snore.
• Cannot be woken by shouting their name or grinding your knuckles on their breastbone.
• Lips, fingertips, or the face turning blue, grey, or unusually pale.
• Limp body, or pupils shrunk to pinpoints.
• A seizure, or a heartbeat that is very slow or very irregular.

Any single item on that list is enough. You do not need several, and you do not need to be certain it was 7-OH.

Signs that still need medical attention

Heavy sedation where the person still rouses, repeated vomiting, confusion, a racing heart, sweating with tremor, or agitation that will not settle. None of these can wait until morning. They can be the front edge of something worse, particularly if the amount taken is unknown or the product was unfamiliar. Poison Help at 1-800-222-1222 can tell you whether to sit tight or go in.

Why a 7-OH overdose is an opioid emergency

7-hydroxymitragynine is a mu-opioid receptor agonist, the same receptor morphine and fentanyl act on. The failure mode is the same: the drive to breathe is suppressed, and the person stops breathing before anything else does. Breathing is the thing to watch. In a 2025 study of breathing in rats, 7-OH produced respiratory depression comparable with morphine, and it was 4.5 times as potent as morphine at halving the volume of air the animals moved each minute.

Why potency varies between products

7-OH occurs in the kratom plant only in trace amounts; the DEA puts it at less than two percent of the plant's alkaloid content. What is sold under the name is concentrated, or made from mitragynine in a one-step chemical reaction. The Food and Drug Administration's page Hiding in Plain Sight: 7-OH Products sets these intentionally enhanced or concentrated formulations apart from products that carry only trace amounts. Strength is unpredictable from one product to the next, so two packages with the same name can behave very differently. Treat every new package as unknown. That is how someone with a stable routine overdoses.

Mixing with alcohol, benzodiazepines, or other opioids

Every one of those also suppresses breathing. Combined, the effect is additive and the threshold for a dangerous outcome drops sharply. Treat that situation as higher risk and call sooner. Tell the paramedics everything that was taken, because the treatment depends on it.

Does naloxone work on 7-OH

Yes. Because 7-OH acts on the mu-opioid receptor, naloxone displaces it and reverses the respiratory depression. In the rat-breathing study, naloxone fully reversed the respiratory depression caused by 7-OH, just as it did for morphine. A published human case, Kratom (Mitragynine) Ingestion Requiring Naloxone Reversal, describes a 38-year-old woman brought to an emergency department with slowed breathing after using kratom. Two doses of naloxone brought her breathing rate up and her alertness back.

Give naloxone whenever breathing is slow, shallow or stopped, whatever was taken: a 7-OH product, kratom leaf, or something you cannot identify. You do not need to know what was in the package first. The body converts some of the mitragynine in kratom into 7-OH, and naloxone has no effect on someone who has no opioid in their system, so giving it costs nothing if you are wrong.

You may come across the claim that naloxone does not work on mitragynine, the main alkaloid in kratom leaf. It traces to the same rat study, which found that mitragynine raised the breathing rate instead of lowering it, and that naloxone did not change that rise. There was no slowed breathing for naloxone to reverse. That finding says nothing about a person whose breathing is failing, and it is not a reason to hold naloxone back.

One dose may not be enough. If breathing has not improved two to three minutes after a dose, give another, and keep giving a dose every two to three minutes until the person wakes up. If they become very sleepy again, give another. Naloxone works for 30 to 90 minutes, and it can wear off before the 7-OH does, so the person can slide back after seeming fine. That is why the ambulance still comes even when it works.

What to do while you wait for paramedics

Put the person on their side, lower arm stretched out and upper knee bent forward so they cannot roll onto their face. That is the recovery position, and it stops someone choking if they vomit while unconscious.

Do not leave the room. Stay with them and keep checking that the chest is rising. If it stops and you know rescue breathing or CPR, start. Do not use a cold shower, do not try to make them vomit, and do not leave them to sleep it off, which is the most common and most costly mistake here. Our guide on how to respond to a drug overdose sets out the full procedure.

Arizona's Good Samaritan protection

People hesitate to call because they are afraid of what happens next. Arizona law addresses that directly. Under A.R.S. section 13-3423, someone who in good faith seeks medical assistance for a person experiencing a drug-related overdose may not be charged or prosecuted for possession or use of a controlled substance or paraphernalia where the evidence came from seeking that help. It covers the person who overdosed as well as the caller, and it counts calling 911, law enforcement, poison control, or an emergency department as seeking help.

It is not blanket immunity and does not reach unrelated offenses or distribution charges. For the decision in front of you, it covers what people actually fear.

Where 7-OH stands with the FDA and DEA

As of October 14, 2026, 7-OH is not federally scheduled. On that date the Drug Enforcement Administration published a notice of intent to temporarily place 7-OH and a related compound, mitragynine pseudoindoxyl, in Schedule I above a specified threshold, and said that in a separate document it is withdrawing its July 2026 notice of intent on 7-OH. A notice of intent is not the order itself, and nothing is scheduled under it yet: the DEA says the temporary scheduling order will be published in the Federal Register on or after November 13, 2026. Mitragynine pseudoindoxyl is already in Schedule I under a temporary order the DEA published on August 26, 2026, which stays in effect until it expires or the new order is published and that order withdrawn.

So read past any source telling you 7-OH is already scheduled. Our guide to the federal and Arizona law on 7-OH covers the detail. For the decision in front of you it changes nothing: legal status says nothing about what a substance does to breathing.

After the emergency

An overdose can be the first time a family sees the size of the problem. 7-OH carries a risk of tolerance and dependence, which our guide on whether 7-OH is addictive explains.

Guiding Road Recovery Center is a men-only program in the Phoenix metro, offering residential, partial hospitalization, and intensive outpatient care along with supportive housing. It does not provide detox on site. Where detox is the first step, the admissions team coordinates it with a medical partner.

Whether medication belongs in his plan is a decision for him and his clinicians, not a question to settle from a website. Where the concern is treatment rather than an emergency, 7-OH addiction treatment covers the program. For confidential information and referrals once the emergency is over, the Substance Abuse and Mental Health Services Administration runs a free National Helpline at 1-800-662-4357.
