Vyvanse (Lisdexamfetamine): Uses, Side Effects & Risks You Should Know

Vyvanse and Lisdexamfetamine

Table of Contents

Vyvanse is a prescription stimulant commonly used to treat ADHD and binge eating disorder. While it can be effective when used as directed, it also carries risks for dependence, misuse, and serious side effects, especially when taken without medical guidance. Understanding what Vyvanse does, how it works, and its potential dangers can help you or a loved one make safer, more informed decisions.

What Is Vyvanse?

Vyvanse (lisdexamfetamine dimesylate) is a central nervous system (CNS) stimulant. Unlike many ADHD medications that begin working immediately, Vyvanse is a prodrug, meaning it must be metabolized by the body before becoming active. This design produces a smoother onset and a longer-lasting effect.

FDA-approved uses include:

Not approved for:

  • Weight loss
  • Cognitive enhancement
  • Staying awake or working longer hours

Misusing Vyvanse for productivity or weight control is increasingly common and significantly raises the risk of addiction.

How Vyvanse Works

Vyvanse increases the levels of key neurotransmitters in the brain:

  • Dopamine (motivation, reward)
  • Norepinephrine (focus, alertness)

This leads to improved concentration, reduced impulsivity, and better task completion for people with ADHD. For individuals without ADHD, however, the dopamine surge can feel euphoric, and that’s where misuse risks begin.

Common Side Effects of Vyvanse

Vyvanse can cause both mild and significant side effects, including:

Physical side effects

  • Increased heart rate
  • Increased blood pressure
  • Dry mouth
  • Loss of appetite
  • Weight loss
  • Trouble sleeping
  • Nausea
  • Sweating

Mental and emotional side effects

  • Anxiety or jitteriness
  • Irritability
  • Mood swings
  • Social withdrawal
  • Hyperfocus to the point of burnout

Severe side effects (seek help immediately)

  • Chest pain
  • Shortness of breath
  • Hallucinations
  • Paranoia
  • Aggressive behavior
  • Suicidal thoughts

Is Vyvanse Addictive?

Yes. Although Vyvanse is designed to have a slower onset, it still contains amphetamine, which has addictive potential.

People may develop:

  • Tolerance (needing higher doses)
  • Psychological craving
  • Dependence
  • Withdrawal symptoms when stopping

Misuse includes:

  • Taking higher doses than prescribed
  • Using without a prescription
  • Crushing or chewing the capsules
  • Taking it to lose weight or enhance performance

These behaviors significantly increase the risk of addiction.

Vyvanse Withdrawal Symptoms

Stopping Vyvanse abruptly can cause uncomfortable withdrawal effects:

  • Extreme fatigue
  • Depression
  • Irritability
  • Sleep disturbances
  • Brain fog
  • Increased appetite
  • Strong cravings

Withdrawal can last several days to weeks depending on dose and duration of use.

Who Should Avoid Vyvanse?

Vyvanse may not be appropriate if you have:

  • Heart disease
  • High blood pressure
  • Anxiety disorders
  • Bipolar disorder
  • History of substance use disorder
  • Thyroid conditions
  • Glaucoma

Always consult with a medical professional before starting or adjusting stimulant medications.

Vyvanse and Alcohol

Mixing Vyvanse with alcohol is risky because:

  • Stimulants mask alcohol intoxication
  • Increased risk of alcohol poisonin
  • Heart strain from combining a stimulant + depressant
  • Higher chance of risky decisions, dehydration, or overheating

Vyvanse Misuse Among Students & Professionals

Vyvanse misuse is increasingly common in:

  • College students
  • High-performance professionals
  • Individuals seeking weight loss
  • Athletes or gym-goers

Although often viewed as a “productivity booster,” misuse increases the risk of:

  • Dependence
  • Cardiovascular complications
  • Mood instability
  • Psychosis in severe cases

Frequently Asked Questions

How long does Vyvanse last?

Vyvanse typically lasts 10–14 hours, depending on your metabolism and dosage. Most people feel the strongest effects within the first 4–6 hours, with a gradual taper rather than a sudden “crash.” Because it’s a prodrug, Vyvanse activates more slowly and tends to provide smoother, sustained focus throughout the day.

What drug is in Vyvanse?

Vyvanse contains lisdexamfetamine, a long-acting stimulant medication. Lisdexamfetamine is converted in the body into dextroamphetamine, which is the active stimulant responsible for its therapeutic effects in ADHD and binge eating disorder.

How long does Vyvanse stay in your system?

Vyvanse and its active metabolite (dextroamphetamine) stay in the body for different lengths of time:

Blood: up to 24 hours
Urine: 2–3 days
Saliva: 1–2 days
Hair: up to 90 days

Heavy or prolonged use can extend detection times.

Is Vyvanse a controlled substance?

Yes. Vyvanse (lisdexamfetamine) is classified as a Schedule II controlled substance in the United States. This is the same category as Adderall, due to its potential for misuse, dependence, and addiction.

Can you snort Vyvanse?

Vyvanse should never be snorted. While some people misuse stimulant medications this way, Vyvanse is a prodrug, meaning it requires digestion to activate. Snorting it will not make it “hit harder”, but it can cause:

– Severe nasal and sinus damage
– Dangerous heart strain
– Higher risk of overdose
– Increased addiction potential

Does Vyvanse cause weight loss?

Weight loss is a common side effect of Vyvanse. The medication reduces appetite and increases energy expenditure, which can lead to:

– Decreased daily calorie intake
– Unintentional weight loss
– Difficulty maintaining nutrition

For some people, this side effect becomes severe and requires medical monitoring.

Can you take Vyvanse while pregnant?

Vyvanse is not generally recommended during pregnancy unless the benefits clearly outweigh the risks. Stimulants may increase the risk of:

– Preterm birth
– Low birth weight
– Blood pressure complications
– Withdrawal symptoms in newborns

Always speak with a medical provider before continuing or stopping Vyvanse during pregnancy.

Is Vyvanse an amphetamine?

Yes. Vyvanse is a type of amphetamine-based stimulant. The lisdexamfetamine in Vyvanse converts into dextroamphetamine, which is the active ingredient found in many ADHD medications.

Can you drink on Vyvanse?

Mixing alcohol with Vyvanse is dangerous. Stimulants mask the sedating effects of alcohol, which can lead to:

– Drinking more than intended
– Blackouts
– Alcohol poisoning
– Irregular heart rhythm
– Dehydration
– Risky decision-making

It’s best to avoid drinking while taking Vyvanse.
