- Stimulant withdrawal typically starts with a "crash" — heavy fatigue, long or disturbed sleep, big appetite, and low mood — followed by a longer stretch of cravings, flat mood, and reduced ability to feel pleasure.
- Unlike alcohol or benzodiazepine withdrawal, stimulant withdrawal is rarely directly medically dangerous, but this does not make it safe: depressed mood and suicidal thoughts can occur and must be taken seriously.
- There are currently no medications approved by the FDA specifically for stimulant withdrawal or stimulant use disorder; care is largely supportive, with counseling approaches such as CBT and contingency management for the underlying disorder.
- Stopping a prescribed ADHD stimulant is different from recovering from stimulant use disorder — but either way, changes should be planned with the prescriber, not made abruptly and alone.

When someone who has been using a stimulant regularly cuts down or stops, the brain and body need time to readjust — a period known as withdrawal. With stimulants such as amphetamines (including some ADHD medicines and methamphetamine), methylphenidate, and cocaine, this usually begins with a “crash”: heavy fatigue, a lot of sleep or restless sleep, a strong appetite, and low, flat mood. A longer phase of cravings, poor motivation, and reduced ability to feel pleasure can follow. Stimulant withdrawal is rarely directly medically dangerous — but low mood and thoughts of suicide can occur, and those are serious. The information below is educational only and is not a plan to stop any medication by yourself.
If you or someone you care about is going through this, the process is safer with support. What follows — drawn from MedlinePlus, SAMHSA, and NCBI Bookshelf — is a plain-language overview of what withdrawal can feel like, why mood is the key safety concern, and where to turn.
What stimulant withdrawal is
Stimulants speed up activity in the brain and body, pushing the reward and alertness systems hard until the brain adapts. When the stimulant is reduced or stopped, that system is briefly left running low — which is why the classic pattern is the near-opposite of being high: exhaustion instead of energy, hunger instead of appetite loss, and a heavy, joyless mood instead of euphoria. According to MedlinePlus, stimulant withdrawal generally lacks the dramatic physical signs of alcohol or opioid withdrawal; the hardest part is usually psychological.
A general stimulant withdrawal timeline
MedlinePlus and NCBI Bookshelf describe withdrawal unfolding in rough stages. The table below is a general picture only — real timelines vary with the stimulant, the amount and length of use, and the person. Cocaine leaves the body quickly, so its crash can begin within minutes to hours; longer-acting amphetamines may start more slowly.
| Phase | Roughly when | What it can feel like |
|---|---|---|
| The “crash” | Hours to a few days after the last use | Intense fatigue, long or disturbed sleep, big increase in appetite, low mood, agitation, strong cravings |
| Acute withdrawal | Roughly the first 1–2 weeks | Continued low or flat mood, poor motivation, trouble concentrating, vivid or unpleasant dreams, ongoing cravings |
| Longer (protracted) phase | Weeks and sometimes longer | Reduced ability to feel pleasure (anhedonia), low energy, on-and-off cravings that ease over time |
Common symptoms
Because withdrawal is mostly psychological, symptoms cluster around mood, energy, sleep, and appetite. MedlinePlus and NCBI Bookshelf describe features such as:
- Fatigue and low energy — often profound in the first days.
- Sleep changes — many people sleep a great deal (hypersomnia), while others have insomnia or restless, vivid, unpleasant dreams.
- Increased appetite.
- Depressed mood, irritability, anxiety, and agitation.
- Anhedonia — a reduced ability to feel pleasure or interest, which can make ordinary activities feel flat.
- Cravings — sometimes strong, and a major reason support matters in this window.
Some people also feel foggy or unusually suspicious. Symptoms usually ease over time.
Is stimulant withdrawal dangerous?
Compared with alcohol or benzodiazepine withdrawal — which can cause life-threatening seizures — stimulant withdrawal is rarely directly dangerous to the body, and MedlinePlus notes it does not typically produce the severe physical signs of some other withdrawals. That is reassuring, but it does not mean withdrawal is harmless.
The most important safety point is emotional. As MedlinePlus describes, depression during and after stimulant withdrawal can be significant and, after long heavy use, may last for weeks or months — and it can include thoughts of suicide. SAMHSA likewise identifies depressive symptoms and suicidal thinking as among the top concerns to watch for in people who use stimulants. So “it’s not physically dangerous” does not mean it is safe to white-knuckle alone. If low mood becomes heavy or hopeless, that deserves prompt attention, not waiting it out.
Treatment: supportive care, because there is no specific medicine yet
An important fact from SAMHSA and NCBI Bookshelf: there are currently no medications approved by the U.S. FDA specifically for stimulant withdrawal, or for stimulant use disorder more broadly. Care during withdrawal is largely supportive — rest, nutrition, a calm environment, monitoring of mood, and treatment of specific symptoms as needed.
For the underlying stimulant use disorder, the strongest evidence is behavioral. SAMHSA highlights approaches such as contingency management, cognitive behavioral therapy (CBT), community reinforcement, and motivational interviewing, sometimes alongside supports like exercise. These are the backbone of recovery and are worth starting with a professional.
Stopping a prescribed ADHD stimulant is a different situation
It is worth separating two things, without judgment about either. Many people take a prescribed stimulant — such as an amphetamine or methylphenidate product — safely for ADHD, and stopping that medicine is not the same as recovering from stimulant use disorder. NCBI Bookshelf resources note that when an ADHD stimulant is stopped, some people notice a temporary “rebound” (such as irritability or a return of ADHD symptoms) rather than a classic withdrawal syndrome. Either way, the safe move is the same: talk with the prescriber before changing anything, so the timing and any tapering can be planned and your symptoms monitored — rather than stopping abruptly on your own.
When to seek help — including urgent help
Reach out to a clinician if withdrawal is hard to manage, if mood stays low, or if cravings feel overwhelming. Seek urgent help in these situations:
- Thoughts of suicide or self-harm, or feeling hopeless — call or text 988 for the Suicide & Crisis Lifeline, available 24/7. This is the single most important number in this article.
- Chest pain, a racing or irregular heartbeat, severe agitation, confusion, a very high temperature, or a seizure — call 911. These are more often linked to recent stimulant use or overdose than to withdrawal itself, but they are emergencies.
- A suspected overdose or medication concern — Poison Control is at 1-800-222-1222.

Frequently asked questions
How long do stimulant withdrawal symptoms last?
It varies. The “crash” often runs from hours to a few days, more acute symptoms usually ease over the first week or two, and a longer phase of low energy, flat mood, and on-and-off cravings can linger for weeks before improving. The specific stimulant and how much and how long it was used all matter.
Is stimulant withdrawal dangerous?
It is rarely directly dangerous to the body, unlike alcohol or benzodiazepine withdrawal. The main risk is emotional: depression and, in some people, suicidal thoughts. If mood becomes heavy or hopeless, treat it as serious and call or text 988.
Is there a medication for stimulant withdrawal?
No medication is currently FDA-approved specifically for stimulant withdrawal or stimulant use disorder. Care is largely supportive, and the underlying disorder is treated mainly with counseling approaches such as CBT and contingency management. A clinician can still help manage specific symptoms and watch for safety concerns.
I take a prescribed ADHD stimulant. Will I have withdrawal if I stop?
Stopping a prescribed ADHD stimulant is not the same as recovering from stimulant use disorder. Some people notice a temporary “rebound,” such as returning ADHD symptoms or irritability, rather than a classic withdrawal syndrome. Either way, plan any change with your prescriber instead of stopping abruptly on your own.
Where can I find help right now?
