Signs Your Vyvanse Dose is Too High

Vyvanse is a prescription drug used to manage ADHD or BED (binge eating disorder). When taken at the right dosage, it can be a helpful tool for improving focus, managing impulses, and promoting emotional balance. However, taking too much Vyvanse can lead to serious side effects that may impact physical and mental health. 

This page explores what Vyvanse is, how it works, and the signs your Vyvanse dose is too high. You will also discover how to connect with compassionate and effective addiction treatment.

What Is Vyvanse?

Vyvanse, also known by its generic name lisdexamfetamine, is a prescription medication that’s often used to manage ADHD (attention deficit hyperactivity disorder) and BED (binge eating disorder). As a central nervous system stimulant, it affects chemicals in the brain responsible for regulating focus, attention, and impulse control [1].

Vyvanse is a prodrug, meaning it doesn’t become active until the body processes it, reducing its potential for misuse [2].

This medication is designed to be taken once daily, offering long-lasting effects that help individuals stay focused and manage their symptoms throughout the day. While Vyvanse can be highly effective, it should be used only as prescribed to avoid side effects or risks associated with improper use. 

Uses

Vyvanse is FDA-approved to treat two primary conditions:

1. ADHD: Vyvanse helps children, teens, and adults with ADHD by improving their ability to concentrate, stay organized, and manage impulsive behaviors. These improvements can make a dramatic difference in both academic and social settings.
2. Binge eating disorder: In adults, Vyvanse is used to reduce the number of binge-eating episodes. It helps people gain better control over their eating habits, improving physical and mental health. 

Vyvanse is not prescribed for weight loss or as a general appetite suppressant, as this can lead to dangerous misuse. Its benefits are most effective when used as part of a broader treatment plan, which may include therapy or other interventions. 

Common Dosages

The dosage of Vyvanse varies depending on the individual’s age, condition, and how they respond to the medication. Typically, doctors start people on a low dose and gradually adjust it to find the most effective amount.

For ADHD: 

• Starting dose: 30mg once daily.
• Incremental increases: Doctors may raise the dose by 10 to 20 mg per week if needed.
• Maximum dose: 70mg per day.

For BED:

• Starting dose: 30mg once daily.
• Incremental increases: Dosage is usually increased by 20mg weekly.
• Maximum dose: 50 to 70mg per day.

Follow your doctor’s instructions and never adjust your dosage without their guidance. Taking more than the prescribed amount can increase the risk of side effects or lead to overdose. 

Forms of Vyvanse

Vyvanse is available in two forms:

1. Capsules: These are the most common form and come in various strengths, ranging from 10 to 70mg. For those who have trouble swallowing pills, the capsule contents can be missed with water, orange juice, or yogurt.
   Chewable tablets: These tablets are an alternative for people who prefer not to swallow capsules. Like the capsules, they are available in multiple strengths, from 10 to 60mg. 

Both forms are designed to be taken once daily, preferably in the morning, to avoid sleep disruptions. Regardless of the form, Vyvanse should be used only as directed and stored securely to prevent accidental use or misuse.

Factors That Affect Vyvanse Dosage

Finding the right dosage of Vyvanse isn’t a one-size-fits-all process. Many factors can influence how much of the medication is prescribed and whether adjustments are needed over time. Doctors carefully consider these factors to ensure the medication is safe and effective.

• Age: Vyvanse is approved for use in children aged 6 and older, as well as teens and adults. Children may require smaller doses due to their size and how their bodies process medication. Adults may need higher doses to manage their symptoms effectively, but older adults with slower metabolisms might require adjustments to avoid side effects [3].
• Weight and metabolism:  Unlike some medications, Vyvanse dosage isn’t strictly determined by weight. That said, a person’s metabolism plays a central role. Those with faster metabolisms might process the medication quicker, requiring higher doses, while slower metabolisms could mean smaller doses are sufficient.
• Severity of symptoms: The intensity of a person’s symptoms often dictates the starting dose and adjustments over time. Severe ADHD or binge eating symptoms may require higher doses, while milder cases might be managed with smaller amounts.
• Coexisting medical conditions: Certain health issues like kidney problems can affect how Vyvanse is processed. Individuals with severe kidney disease might be prescribed lower doses to prevent the medication from building up in their system. Other conditions, such as heart problems or high blood pressure, might require additional monitoring or alternative treatments.
• Interactions with other medications: Vyvanse can interact with other medications like antidepressants or MAOIs (monoamine oxidase inhibitors). These interactions may alter how the drug works or increase the risk of side effects. Inform your doctor of all medications and supplements you take before starting Vyvanse.
• Tolerance over time: With long-term use, some people may develop a tolerance to Vyvanse, meaning the same dose becomes less effective [4]. This could lead to dosage adjustments or exploring other treatment options. However, tolerance can also increase the risk of side effects, so any changes should be made under a doctor’s supervision.

 5 Signs Your Vyvanse Dose Is Too High

Taking too much Vyvanse can provoke uncomfortable or dangerous side effects. If you notice any of these symptoms, contact your doctor immediately: 

1. Difficulty sleeping: One of the first signs of a high Vyvanse dose is trouble falling or staying asleep. Vyvanse is a stimulant, and too much of it can overstimulate your central nervous system, triggering insomnia or restless nights.
2. Increased irritability or anxiety: High doses of Vyvanse can cause feelings of unease, nervousness, or anxiety. You may feel unusually irritable or find yourself overreacting to minor issues. These emotional changes can disrupt your daily life and relationships.
3. Physical symptoms: Excess Vyvanse can lead to a rapid heartbeat, high blood pressure, and excessive sweating. You might also experience dry mouth, nausea, or chest pain. These symptoms could signal that your body is struggling to handle the dosage.
4. Jitteriness or hyperactivity: If your dose is too high, you might feel excessively energized, shaky, or jittery. Instead of helping you focus, Vyvanse may make it harder to sit still or concentrate. These symptoms are a sign that the stimulant effect is too strong.
5. Confusion or mood swings: Taking too much Vyvanse can lead to emotional instability or confusion. You might experience sudden mood swings, paranoia, or difficulty thinking. In severe cases, this could escalate into hallucinations or psychosis [5].

 If you experience any of these symptoms, talk to your doctor. Adjusting your dosage can often resolve the issue and help you return to feeling balanced and focused. 

Symptoms of a High Vyvanse Dosage

When the dose of Vyvanse is too high, the medication can overstimulate your system, leading to unpleasant and potentially dangerous side effects. These include: 

• Physical symptoms: High doses of Vyvanse often cause noticeable physical effects, such as rapid heartbeat, high blood pressure, or excessive sweating. Other signs might include nausea, vomiting, dry mouth, and dilated pupils. Some people may also experience tremors or muscle twitching.
• Emotional and mental changes: Too much Vyvanse can lead to feelings of anxiety, restlessness, or irritability. It may also confuse or make it hard to concentrate. Some people may feel paranoid, hallucinate, or experience panic attacks.
• Behavioral changes: Overuse of Vyvanse can lead to hyperactivity, impulsiveness, or an inability to stay calm. Rather than helping you focus, the medication might make it harder to control your behavior.
• Sleep problems: Insomnia is a common sign of a high dose. You may find it difficult to fall asleep or stay asleep, leading to fatigue and difficulty functioning during the day.
• Severe reactions: In rare cases, taking too much Vyvanse can provoke life-threatening complications like heart attack, stroke, or hypertensive crisis. If you or someone you know encounters chest pain, difficulty breathing, or severe confusion, seek emergency medical help.

 How Much Vyvanse Is Too Much in a Day?

The maximum recommended daily dose of Vyvanse is 70mg, Taking more than this can increase the risk of severe side effects and overdose.

 Exceeding this limit amplifies the medication’s intended effects and overstimulates the CNS, prompting symptoms like rapid breathing, irregular heartbeat, and extreme agitation. In severe cases, stimulant overdose can result in seizures, circulatory collapse, or death.

 What Happens When Vyvanse Dose Is Too Low?

When your Vyvanse dose is too low, the medication may not effectively manage your symptoms, leaving you frustrated or unfocused.

• Incomplete symptom relief: For individuals with ADHD, a low dose might not provide enough stimulation to improve focus or reduce impulsivity. You may struggle to complete tasks, stay organized, or manage time effectively.
• Continued binge eating episodes: IN adults with binge eating disorder, a low dose may fail to reduce binge-eating episodes significantly. This could lead to ongoing frustration with treatment progress.
• Subtle signs: Some signs of an insufficient dose are not obvious. You might notice mild improvements in your symptoms but still feel like you’re not functioning at your best. In such cases, consult your doctor to see whether an adjustment is needed. Avoid increasing your dose without speaking to your healthcare provider.

 Can You Take 2 30mg Vyvanse Pills in One Day?

Taking too 30mg Vyvanse pills in one day is not typically recommended unless specifically directed by your doctor. This would result in a total dose of 60mg, which may be close to the maximum daily limit and could pose risks, especially if taken all at once.

Vyvanse is designed to be taken once daily because its effects last 12 to 14 hours Splitting or doubling doses can increase the risk of side effects like jitteriness, nausea, or trouble sleeping.

 If you feel your current dose isn’t working, don’t attempt to take extra pills. Instead, talk to your doctor about adjusting your treatment plan. They can determine the safest and most effective way to manage your symptoms while minimizing side effects and complications.

 Vyvanse Dosage for Children

Vyvanse is commonly prescribed to help children aged 6+ manage symptoms of ADHD. It can improve focus, reduce hyperactivity, and help children stay on task, making a major difference at home and school.

 Children’s bodies process medications differently than adults, so doctors normally start with a low dose and increase it gradually if required. This approach helps them reduce the risk of side effects while identifying the smallest dose that relieves symptoms. Parents and caregivers play a fundamental role in monitoring their child’s response to Vyvanse and communicating concerns to the prescribing physician. 

Common Dosages for Children

The typical starting dose for children with ADHD is 30mg once daily, taken in the morning. Depending on how the child responds, the doctor may increase the dose by 10 or 20mg weekly. The maximum daily dose is 70mg. 

Vyvanse is available in capsules and chewable tablets, making it easier for children to take. The effects last 12 to 14 hours, providing symptom relief throughout the school day and into the evening. 

Signs Vyvanse Dose is Too High for a Child

Children are more sensitive to medication and taking too much Vyvanse can lead to side effects that impact a child’s health, emotions, and behavior. Signs a Vyvanse dose is too high for a child include: 

• Trouble sleeping: If your child struggles to fall asleep or wakes up frequently during the night, this could indicate their dose is too high. Stimulants like Vyvanse can disrupt normal sleep patterns, especially in excessive amounts.
• Extreme irritability or nervousness: Children on a high dose may appear unusually anxious, irritable, or prone to emotional outbursts. They might overreact to minor situations or have difficulty calming down.
• Physical symptoms: Watch for physical signs like a rapid heartbeat, sweating, or complaints of dizziness or stomach pain. These could signal that the medication is overstimulating their system.
• Hyperactivity or jitteriness: Instead of helping your child feel calm and focused, a high dose may make them too energetic, fidgety, or restless. This can interfere with their ability to concentrate or complete tasks.
• Unusual mood or behavior changes: In severe cases, children may experience paranoia, confusion, or hallucinations. These rare but serious symptoms require immediate medical attention.

 If you suspect your child’s dose is too high, contact their doctor right away. Adjustments can often resolve the problem and ensure the medication’s safety and effectiveness. Monitoring your child closely and maintaining open communication with their healthcare provider will help them achieve the best results. 

Vyvanse | FAQs

What If I accidentally took 120 mg of Vyvanse?

Taking 120mg of Vyvanse exceeds the maximum daily recommended dose of 70mg and could trigger severe side effects like high blood pressure, rapid heartbeat, or severe anxiety. If this happens, seek medical attention immediately, even if you feel fine. Symptoms of overdose may worsen over time, so act quickly. 

Is there a risk of misuse with Vyvanse?

Yes, Vyvanse is a stimulant and a Schedule II controlled substance, meaning it has a high potential for misuse and dependence. Misuse can occur when it’s taken in larger doses than prescribed, more frequently, or by someone without a prescription. Always use Vyvanse as directed and store it safely to prevent unauthorized access. 

What happens if I miss a dose?

If you miss a dose of Vyvanse, take it as soon as you remember, but avoid taking it late in the day as it could interfere with sleep. If it’s close to your next scheduled dose, skip the missed one and continue as usual—do not double up on doses to make up for the missed medication.
