Prescription stimulant misuse deserves professional care. Our stimulant addiction treatment in West Palm Beach treats it in adults.
Vyvanse withdrawal can happen when someone who has taken Vyvanse (lisdexamfetamine) for a long time stops suddenly or sharply lowers their dose. Symptoms include low mood or depression, fatigue, vivid unpleasant dreams, changes in sleep, increased appetite and either slowed movement or agitation.[1] Symptoms usually start within a day or two of the last dose, are strongest in the first several days and ease over one to two weeks, though low mood and cravings can last longer.[1][2] Vyvanse withdrawal is rarely physically dangerous, but depression and suicidal thoughts can be serious.
This guide covers what Vyvanse is, why withdrawal happens, common symptoms, a realistic timeline, how to stop safely and how treatment helps when Vyvanse has been misused.

Key takeaways
- Vyvanse can cause physical dependence, and stopping it suddenly after long-term use can cause withdrawal.[1]
- Common symptoms are depression, fatigue, vivid dreams, sleep changes, increased appetite and agitation or sluggishness.[1]
- Withdrawal from amphetamine-type stimulants is usually most intense early and the acute phase lasts about 7 to 10 days.[2]
- No medication is proven to treat amphetamine withdrawal, so care focuses on symptoms, safety and support.[3]
- About 3.9 million Americans misused prescription stimulants in 2024.[4]
What Is Vyvanse?
Vyvanse (lisdexamfetamine dimesylate) is a prescription central nervous system stimulant. The FDA has approved it to treat:[1]
- ADHD in adults and children 6 years and older
- Moderate to severe binge eating disorder in adults
Vyvanse is not approved for weight loss.[1] It is a “prodrug,” meaning it is inactive until the body converts it into dextroamphetamine, mainly in red blood cells. Dextroamphetamine increases dopamine and norepinephrine in the brain, which improves focus and reduces impulsivity. In adults, dextroamphetamine has a half-life of about 10 to 11 hours, which helps explain why Vyvanse lasts most of the day.[1]
Because it is an amphetamine, Vyvanse is a Schedule II controlled substance. Its FDA label carries a boxed warning that it has a high potential for abuse and misuse, which can lead to substance use disorder, including addiction, as well as overdose and death.[1] In 2023, the FDA required this warning to be updated across all prescription stimulants.[5]

Why Does Vyvanse Withdrawal Happen?
With regular use, the brain adapts to the extra dopamine and norepinephrine that Vyvanse provides. When the medication is suddenly stopped or the dose is cut sharply, the brain’s reward and energy systems take time to readjust. That gap causes withdrawal.[1]
Physical dependence can develop even when Vyvanse is taken exactly as prescribed, and dependence alone is not addiction. Withdrawal tends to be more intense when someone has:
- Taken higher doses or taken Vyvanse for a long time
- Misused Vyvanse by taking more than prescribed, taking it without a prescription, or snorting or injecting it
- Used other stimulants, alcohol or drugs at the same time
- A history of depression or another mental health condition
Vyvanse Withdrawal Symptoms
According to the FDA label, withdrawal signs after stopping Vyvanse abruptly or reducing the dose significantly can include:[1]
- Dysphoric mood (feeling down, flat or uneasy)
- Depression
- Fatigue
- Vivid, unpleasant dreams
- Insomnia or sleeping much more than usual
- Increased appetite
- Slowed movements and thinking, or restlessness and agitation
People may also notice:
- Strong cravings, which are a major driver of relapse[3]
- Anxiety and irritability[3]
- Trouble concentrating and low motivation
- A return of ADHD or binge eating symptoms
In people who have been misusing high doses, withdrawal-related depression can be severe and may include suicidal thoughts. Anyone with these thoughts should get help right away.
Vyvanse Withdrawal Timeline
There is little research on Vyvanse withdrawal specifically, so the timeline below is based on studies of amphetamine-type stimulant withdrawal. In one study that tracked people through three weeks of withdrawal, symptoms were most severe in the first 24 hours, declined steadily over the first week and settled to low levels by about day 7 to 10.[2] Everyone is different, and dose, length of use and mental health all affect how withdrawal feels.
| Time since last dose | What to expect |
|---|---|
| 12 to 36 hours | The “crash” begins: tiredness, low mood, increased appetite and cravings |
| Days 2 to 5 | Fatigue, depression, sleep changes, vivid dreams and trouble concentrating are often strongest |
| Days 5 to 10 | Physical symptoms ease; mood and energy gradually improve |
| Weeks 2 to 4 | Most people feel close to normal, though cravings, low mood and sleep problems can come and go |
The Crash (First 1 to 2 Days)
Because Vyvanse lasts most of the day, the first signs usually appear within a day or so of the last dose. Many people feel exhausted, sleep a lot, feel hungry and notice a drop in mood.
Acute Withdrawal (Days 2 to 10)
This is when depression, fatigue, poor focus and cravings tend to be most noticeable. Sleep may be heavy or broken, with vivid dreams. Symptoms usually decline steadily through this period.[2]
After the First Two Weeks
Most physical symptoms have passed. Some people, especially those who misused high doses for a long time, continue to have low mood, low motivation, sleep problems or cravings for several weeks. If ADHD or binge eating symptoms return, they should be addressed with a doctor rather than treated as withdrawal.
How Long Does Vyvanse Stay in Your System?
Vyvanse itself is converted quickly, with a half-life of under one hour. Its active form, dextroamphetamine, has a half-life of about 10 to 11 hours in healthy adults and about 9 hours in children.[1] It takes several half-lives for a drug to clear the body, so dextroamphetamine is typically eliminated within about two to three days, which lines up with when withdrawal symptoms begin.
How to Stop Taking Vyvanse Safely
Talk to your prescriber before stopping or changing your dose. The Vyvanse label doesn’t include a specific tapering schedule, but your doctor may recommend lowering the dose gradually, especially if you’ve taken it for a long time, take a high dose or have had withdrawal symptoms before. A plan might also include:
- Scheduling the stop during a lower-stress time
- Prioritizing sleep, regular meals and light exercise
- Monitoring mood closely and having a plan for depression
- Treating ADHD or binge eating with other options if needed
- Avoiding alcohol and other drugs, which can worsen mood and sleep
If you’ve been misusing Vyvanse, taking it with other substances or have a history of depression or suicidal thoughts, a supervised detox program is the safer choice.
- 24/7 medical monitoring
- Comfort medications when appropriate
- Private, peaceful setting in West Palm Beach
How Is Vyvanse Withdrawal Treated?
No medication has been proven to treat amphetamine withdrawal itself.[3] Instead, medical detox focuses on safety, comfort and preparing for longer-term recovery.
- Medical monitoring: staff check vital signs, sleep, nutrition and mood.
- Symptom-focused medication: doctors may treat insomnia, anxiety, agitation or depression as needed. Research on medications like mirtazapine for amphetamine withdrawal is mixed.[3] Learn more about using antidepressants in addiction treatment.
- Mental health support: 24/7 access to staff, plus individual and group counseling, helps people cope with depression and cravings.
- Suicide risk screening: regular check-ins on mood and safety, with a plan if risk rises.
Treatment for Vyvanse Misuse and Addiction
When Vyvanse use has turned into misuse or addiction, detox is only the first step. Evidence-based care for stimulant use disorder includes:[6]
- Contingency management: rewards for drug-free test results, one of the most effective treatments for stimulant addiction.
- Cognitive behavioral therapy: helps people manage cravings, triggers and stress.
- Dual diagnosis treatment: treats ADHD, depression, anxiety or eating disorders alongside addiction. Untreated ADHD is a common reason people return to stimulants.
- Relapse prevention and aftercare: outpatient therapy, support groups and alumni programs keep people connected after treatment.
Signs that Vyvanse use may have become a problem include taking more than prescribed, running out early, getting pills from others, snorting or injecting the capsule contents, feeling unable to function without it, and continuing to use despite problems at work, school or home.

Frequently Asked Questions
What are the symptoms of Vyvanse withdrawal?
Common symptoms include depression or low mood, fatigue, vivid unpleasant dreams, insomnia or oversleeping, increased appetite, and slowed movement or agitation. Cravings, irritability and trouble concentrating are also common.
How long does Vyvanse withdrawal last?
Symptoms usually start within a day or two, peak in the first several days and ease over one to two weeks. Low mood and cravings can last a few weeks for some people, especially after misuse.
Can you stop taking Vyvanse cold turkey?
Stopping suddenly isn’t usually dangerous physically, but it can cause uncomfortable withdrawal and a drop in mood. Talk to your prescriber first; a gradual taper may make the process easier.
Is Vyvanse withdrawal dangerous?
The physical symptoms are rarely dangerous. The main risks are severe depression, suicidal thoughts and relapse. Get immediate help if you have thoughts of harming yourself.
Does Vyvanse withdrawal cause depression?
Yes. Depression and dysphoric mood are among the most common withdrawal symptoms listed in the FDA label.
Why am I so tired after stopping Vyvanse?
Fatigue is a hallmark of stimulant withdrawal. Your brain is readjusting to lower dopamine and norepinephrine levels, and energy usually improves within one to two weeks.
Can Vyvanse withdrawal cause increased appetite?
Yes. Vyvanse suppresses appetite, so hunger often increases after stopping. Increased appetite is listed as a withdrawal sign in the FDA label.
Is Vyvanse addictive?
Vyvanse has a high potential for abuse and misuse, which can lead to addiction, according to its FDA boxed warning. The risk is higher with high doses and when it is snorted or injected.
Is Vyvanse withdrawal the same as Adderall withdrawal?
They are very similar because both are amphetamines. Vyvanse’s longer action may make the crash feel more gradual for some people. Read about Adderall withdrawal and Ritalin withdrawal.
