Quick answer: 7-OH (7-hydroxymitragynine) is an opioid-acting compound related to kratom. It is sold in concentrated tablets, shots, gummies and strips at gas stations, smoke shops and online. Regular use can cause physical dependence, and the FDA reports that people present with opioid-like withdrawal when they stop. Expect symptoms such as anxiety, aches, sweating, runny nose, insomnia, cramps, diarrhea and strong cravings. Research is still limited, so there is no established day-by-day timeline, and no medication is approved specifically for 7-OH withdrawal. Medically supervised detox is the safer route for heavy daily users or anyone who also uses other opioids, alcohol or sedatives.
Call 911 or go to an emergency room if you or someone with you:
- Is very drowsy, cannot be woken, or is breathing slowly or not at all (give naloxone if you have it)
- Has a seizure, chest pain, fainting or confusion
- Cannot keep fluids down because of vomiting or diarrhea
- Is thinking about suicide: call or text 988 (Suicide & Crisis Lifeline)
After a period without 7-OH or other opioids, tolerance drops. Going back to a previous amount can cause an overdose.
What is 7-OH?
7-hydroxymitragynine, usually shortened to 7-OH, is one of the alkaloids linked to the kratom plant (Mitragyna speciosa). According to the FDA, it makes up less than 2% of the total alkaloid content of natural kratom leaves. NIDA notes that mitragynine, kratom’s main alkaloid, is also converted to 7-OH in the body.
The 7-OH products now on shelves are very different from plain leaf. An FDA scientific assessment concluded that concentrated 7-OH is likely made synthetically by chemically converting mitragynine, because extracting it directly from the plant would not be economically feasible. These products are sold as tablets, gummies, liquid shots, powders and dissolvable strips, often in gas stations, convenience stores and smoke shops. In a review of 250 products cited in the DEA’s October 2026 notice, the amount per serving ranged from 1 mg to 700 mg.
If you use plain kratom leaf, see our guide to kratom withdrawal symptoms and timeline.
Why 7-OH causes dependence and withdrawal
7-OH acts on the brain’s mu-opioid receptors, the same target as morphine, oxycodone and fentanyl. The DEA describes it as sharing a pharmacological profile similar to Schedule II opioids like morphine. The FDA states that it has substantially greater mu-opioid receptor potency than mitragynine and morphine. In lab studies, 7-OH causes respiratory depression that naloxone reverses, the same way it reverses other opioids.
The DEA’s October 2026 scheduling notice summarizes the preclinical evidence: 7-OH carries a high abuse potential, with tolerance, dependence and respiratory depression comparable to classic opioid painkillers, and fatal overdoses involving 7-OH have been reported. When a body has adapted to a daily opioid and that opioid is removed, withdrawal follows.
The FDA’s assessment lists clinical presentations of 7-OH use that include euphoria, sedation, respiratory depression and opioid-like withdrawal syndromes. In poison center data the FDA reviewed from February to April 2025, withdrawal was recorded in 8 of 53 exposure cases involving 7-OH.
7-OH withdrawal symptoms
Because 7-OH withdrawal is opioid-like, the symptoms people describe match opioid withdrawal. MedlinePlus groups opioid withdrawal symptoms into early and later stages:
| Stage | Common symptoms |
|---|---|
| Early | Anxiety, agitation, muscle aches, watery eyes, runny nose, sweating, yawning, trouble sleeping |
| Later | Stomach cramps, diarrhea, nausea, vomiting, dilated pupils, goosebumps |
Strong cravings, low mood and restlessness are also common reasons people go back to using within the first few days.
Is there a 7-OH withdrawal timeline?
Not a reliable one yet. Concentrated 7-OH products are new, and there are no published clinical studies that map withdrawal day by day. What is known:
- It is cleared fairly quickly. The FDA’s review cites studies where the mean half-life of 7-OH after kratom dosing was about 1.7 to 4.7 hours. Short-acting opioids generally produce withdrawal sooner after the last dose than long-acting ones.
- Dose varies enormously. With servings from 1 mg to 700 mg, two people who both “take 7-OH” can have very different levels of dependence.
- Mixed use is common. Many people use 7-OH alongside kratom leaf, other opioids, alcohol or sedatives, and each changes the picture.
Be cautious with any website that promises an exact 7-OH withdrawal timeline. The honest answer is that it depends on the product, the dose, how long you have used it and what else you use.
Is 7-OH withdrawal dangerous?
Opioid withdrawal is painful but usually not life-threatening on its own. The real risks are:
- Dehydration from vomiting and diarrhea
- Relapse and overdose: tolerance drops quickly, so returning to a previous amount, or switching to street opioids that may contain fentanyl, can be fatal
- Other substances: withdrawal from alcohol or benzodiazepines at the same time can cause seizures and needs medical care
- Mental health: anxiety and depression can spike. If you have thoughts of suicide, call or text 988.
How 7-OH withdrawal is treated
NIDA states that there are currently no approved medical therapies specifically for kratom withdrawal or kratom use disorder. In practice, clinicians treat it as opioid withdrawal:
- Medical assessment of what was used, how much and how often, plus any other substances
- Symptom management for nausea, diarrhea, aches, anxiety and sleep, with fluids and monitoring
- Opioid use disorder medication when appropriate. A 2021 case series and systematic review in the Journal of Addiction Medicine reported using buprenorphine-naloxone to treat kratom withdrawal and dependence. Whether it is right for you is a decision for a physician.
- Therapy and a plan for after detox, because the first weeks after stopping carry the highest relapse risk
Medically supervised detox is usually the safer choice if you use 7-OH several times a day, have tried to stop and could not get past the first few days, also use other opioids, alcohol or benzodiazepines, or have depression or thoughts of suicide.

Is 7-OH legal? The 2026 DEA action
- 2025: In July, the FDA sent warning letters to seven companies selling 7-OH products. HHS and the FDA then recommended that the DEA begin scheduling 7-OH above a set threshold.
- July 2026: The DEA announced its intent to temporarily place 7-OH in Schedule I. That notice was later withdrawn and replaced.
- October 14, 2026: The DEA published a new notice of intent to temporarily place 7-OH and mitragynine pseudoindoxyl in Schedule I when a product contains more than 1 mg per gram (solids) or 1 mg per milliliter (liquids), or when the ratio of mitragynine to 7-OH is less than 100 to 1. The temporary order can be published on or after November 13, 2026, and temporary scheduling lasts two years, with a possible one-year extension.
In July 2026, the DEA said its action does not apply to botanical kratom with naturally occurring 7-OH below the threshold, and HHS has said it is not aimed at natural leaf kratom without enhanced 7-OH levels. Once the order takes effect, enhanced 7-OH products above the threshold become Schedule I. For someone who is dependent, that can mean a sudden loss of supply, so it is worth planning a safe way to stop now rather than being forced into withdrawal later.

Frequently asked questions
How long does 7-OH withdrawal last?
There is no established timeline yet, because concentrated 7-OH products are new and have not been studied clinically in detail. 7-OH is cleared from the body fairly quickly, and its withdrawal is opioid-like. How long it lasts depends on the dose, how long you have used it and whether you use other substances.
Is 7-OH withdrawal worse than kratom withdrawal?
It can be. Concentrated 7-OH products contain far more 7-OH than natural kratom leaf, and 7-OH acts as a strong opioid. Withdrawal after heavy daily use can closely resemble withdrawal from prescription opioids.
Can you die from 7-OH withdrawal?
Opioid-type withdrawal is usually not life-threatening on its own, but severe vomiting and diarrhea can cause dangerous dehydration, and relapse after tolerance drops can cause a fatal overdose. Withdrawal from alcohol or benzodiazepines at the same time can also be dangerous.
Does naloxone (Narcan) work on 7-OH?
In lab studies, naloxone reverses respiratory depression caused by 7-OH. If someone is unresponsive or breathing slowly after using 7-OH, give naloxone if you have it and call 911.
Does insurance cover detox from 7-OH?
Many insurance plans cover medically necessary detox. Coverage depends on your plan. Our admissions team can check your benefits immediately at (844) 798-0516.
