Nuvigil vs Vyvanse
Introduction
For patients with sleep disorders such as narcolepsy or attention deficit hyperactivity disorder (ADHD), certain drugs that modify the concentrations of compounds in the brain associated with wakefulness and focus can aid in managing symptoms. Nuvigil and Vyvanse are two such medications often prescribed for these conditions. Both influence different neurotransmitters in the brain, but each has an effect on enhancing alertness and concentration. Nuvigil, also known as Armodafinil, is a dopamine reuptake inhibitor which affects levels of dopamine to promote wakefulness. On the other hand, Vyvanse falls under a category called stimulants; specifically it’s a prodrug of dextroamphetamine designed to release this active compound over time thus improving focus and reducing impulsivity related to ADHD.
What is Nuvigil?
Armodafinil (the generic name for Nuvigil) is a stimulant that promotes wakefulness. It was approved by the FDA in 2007 as a development upon previous drugs meant to treat narcolepsy, sleep apnea and shift work disorder. Armodafinil works by increasing levels of dopamine in the brain by reducing its reuptake into nerves, effectively keeping it active for longer than usual. This drug is often prescribed to improve wakefulness and reduce excessive daytime sleepiness.
On the other hand, Lisdexamfetamine (the generic name for Vyvanse), which was first approved by the FDA in 2008, belongs to a class of drugs known as central nervous system stimulants used primarily for attention deficit hyperactivity disorder (ADHD) and binge eating disorder treatment. Vyvanse increases levels of dopamine and norepinephrine between synapses in your brain leading to increased concentration, focus, alertness and controlled behavior.
While both medications are effective at promoting wakefulness and enhancing focus or cognition; however they have different mechanisms of action with Nuvigil having more selective influence on dopamine with fewer side effects while Vyvanse has stronger effects on both dopamine and norepinephrine neurotransmitters.
What conditions is Nuvigil approved to treat?
Nuvigil is approved for the treatment of several waking disorders:
- Narcolepsy, a neurological disorder that causes excessive daytime sleepiness
- [Sleep apnea](https://www.withpower.com/clinical-trials/sleep-apnea), which can cause interrupted sleep and subsequent excessive daytime drowsiness
- Shift work disorder (SWD), a condition characterized by insomnia or excessive sleepiness affecting people who frequently rotate shifts or work at night.
On the other hand, Vyvanse is used primarily to treat attention deficit hyperactivity disorder (ADHD) in both adults and children aged 6 years and above. It's also used to treat moderate-to-severe binge eating disorder in adults.
How does Nuvigil help with these illnesses?
Nuvigil works to manage conditions like sleep apnea, narcolepsy and shift work disorder by promoting wakefulness. It does this by acting on dopamine—a neurotransmitter, or chemical messenger in the brain involved in reward, motivation, memory, attention and even regulating body movements. Nuvigil is thought to inhibit the reuptake of dopamine into nerves in the brain which increases the amount of available dopamine allowing for increased activity and wakefulness. Just as with serotonin in depression patients, individuals with certain sleep disorders may have imbalances related to their levels of dopamine. Therefore, by increasing available dopamine via a mechanism similar to Prozac's action on serotonin, Nuvigil can help patients manage their condition better.
What is Vyvanse?
Vyvanse is a brand name for lisdexamfetamine, a prodrug of dextroamphetamine. It works by increasing the levels of dopamine and norepinephrine in the brain through its action as a central nervous system (CNS) stimulant. This medication was first approved by the FDA in 2007. Vyvanse is not an amphetamine salt combo like Adderall, meaning it does not contain multiple forms of amphetamines. Its unique formulation means that its side-effect profile is also different to that of medications such as Nuvigil which are used primarily for sleep disorders like narcolepsy and sleep apnea rather than ADHD or binge eating disorder, conditions Vyvanse is commonly prescribed for. The effects on dopamine and norepinephrine can be beneficial in managing symptoms associated with these conditions, especially in patients who do not respond well to typical ADHD medications or appetite suppressants.
What conditions is Vyvanse approved to treat?
Vyvanse is a clinical medication that has been given the green light by the FDA to manage and treat:
- Attention Deficit Hyperactivity Disorder (ADHD) in both children and adults
- Moderate to severe Binge Eating disorder (BED) in adults.
It's worth noting that Vyvanse is not for weight loss, but its efficacy in treating these conditions makes it a vital tool for many patients.
How does Vyvanse help with these illnesses?
Vyvanse, much like Nuvigil, is a medication that enhances wakefulness and attention. It works by increasing the levels of dopamine and norepinephrine in the brain—neurotransmitters responsible for focus, energy and drive. This makes it an effective treatment for conditions such as ADHD or binge eating disorder. However, Vyvanse has a unique mechanism: it's designed to be inactive until metabolized by the body's enzymes—a prodrug—which can help reduce misuse potential. Also notable is its ability to improve symptoms without causing significant spikes in blood pressure or heart rate commonly seen with other stimulants. Therefore, Vyvanse may be preferred when patients do not respond well to traditional stimulant medications (like Nuvigil), or if there are concerns about substance misuse.
How effective are both Nuvigil and Vyvanse?
Both armodafinil (Nuvigil) and lisdexamfetamine (Vyvanse) have established histories of success in treating patients with conditions such as narcolepsy, sleep apnea, shift work disorder, and attention deficit hyperactivity disorder. Armodafinil was approved by the FDA in 2007 followed by Vyvanse a year later. Since they act on different neurotransmitters - dopamine for Nuvigil and both norepinephrine and dopamine for Vyvanse- they may be prescribed under different circumstances.
The efficacy of both drugs has been extensively studied over the years. For example, a randomized controlled trial carried out in 2010 demonstrated that Nuvigil significantly improved wakefulness compared to placebo among adults who experienced excessive sleepiness due to obstructive sleep apnea or narcolepsy. Similarly, multiple studies have shown that Vyvanse successfully reduces symptoms associated with ADHD including impulsivity control problems and difficulty paying attention.
A review article published in 2016 reported about long-term safety profile of Vyvanse suggesting its effectiveness remains stable over time without significant increases in side effects which mainly include dry mouth, insomnia, loss of appetite etc. Although it is commonly used off-label for cognitive enhancement purposes or weight reduction strategy due to its anorexigenic effect but these aren't FDA-approved uses.
Similarly another review conducted around same period highlighted the effectiveness of Nuvigil showing improvement not only in wakefulness but also overall clinical condition as rated by clinicians indicating it can improve health-related quality-of-life measures among people experiencing excessive sleepiness from various causes including shift-work disorder.
It's important to note that while both medications are generally well-tolerated some individuals might experience side-effects ranging from mild like headache & nausea to severe like allergic reactions or psychiatric symptoms hence need close monitoring especially during initial phases after starting any new medication regimen.
One major difference between two lies within their abuse potential where amphetamines like vyvnase carries higher risk than modafinils hence prescribers often choose latter over former when dealing with someone having history of substance misuse disorders.
At what dose is Nuvigil typically prescribed?
Oral dosages of Nuvigil range from 150–250 mg/day, but studies have shown that 150 mg/day is typically sufficient for treating sleep disorders like narcolepsy or shift work disorder in most people. For Vyvanse, doses can vary dramatically depending on the condition it's treating; for ADHD, dosages range from 30-70 mg/day. It's important to remember that these medications should always be taken as directed by a healthcare provider and dosage adjustments should only be made under their guidance. The maximum dosage for Nuvigil should not exceed 250 mg/day while for Vyvanse, it is 70mg/day.

At what dose is Vyvanse typically prescribed?
Vyvanse treatment typically begins at a dosage of 30 mg/day taken orally in the morning. The dose can then be gradually increased by 10-20mg at weekly intervals, with a usual maintenance dose ranging from 30 to 70 mg/day depending on individual patient response. The maximum daily dosage should not exceed 70 mg/day. This may be tested if there is no significant improvement in symptoms after several weeks of treatment at lower dosages. It's important to note that Vyvanse should not be taken in the afternoon or evening due to potential interference with sleep.

Contraindications for Nuvigil and Vyvanse?
Both Nuvigil and Vyvanse, similar to most stimulant medications, may exacerbate symptoms of anxiety or agitation in some individuals. If you notice an increase in these symptoms or any changes in your mental health, it's crucial to contact a healthcare professional immediately.
Neither Nuvigil nor Vyvanse should be taken if you are currently using or have recently stopped using monoamine oxidase inhibitors (MAOIs). It's essential to always inform your physician about all the medications you're taking; MAOIs will require a period of approximately 2 weeks to clear from the system so as to prevent potentially harmful interactions with either Nuvigil or Vyvanse.
How much do Nuvigil and Vyvanse cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Nuvigil (150 mg) is about $750, which works out to approximately $25/day.
- The price for a month's supply (30 capsules) of Vyvanse (50 mg) averages around $378, working out to roughly $12.60 per day.
Thus, if you are on an average dose for both medications, then brand-name Vyvanse is less expensive on a per-day treatment basis. However, remember that cost should not be the primary consideration in determining which medication is right for you; efficacy and side effects must also be taken into account.
As it pertains to their generic counterparts:
- Armodafinil (generic Nuvigil), available in packs ranging from 20 to 100 tablets with strengths varying from 50mg up to 250mg, costs between $0.90 - $3/day depending upon dosage and quantity bought at once.
- Lisdexamfetamine dimesylate (generic Vyvanse) isn't currently available due to existing patents and exclusivity rights. Therefore costs comparisons cannot be made at this time.
Popularity of Nuvigil and Vyvanse
Armodafinil, in its generic form and under brand names such as Nuvigil, was estimated to have been prescribed to about 600,000 people in the US in 2020. Armodafinil accounted for just over 10% of prescriptions for wakefulness-promoting agents in the US. It appears to be a popular choice among "smart drugs" or nootropics due its ability to increase alertness and cognitive function without causing traditional stimulant side effects.
Lisdexamfetamine dimesylate, known by brand versions like Vyvanse, was prescribed to approximately 2.7 million people in the USA during 2020. In the US, lisdexamfetamine accounts for around 15% of prescriptions intended for Attention Deficit Hyperactivity Disorder (ADHD), making it a significant player within this therapeutic area. The prevalence of lisdexamfetamine has generally increased over the last decade due to its efficacy and once-daily dosing convenience.
Conclusion
Both Nuvigil (armodafinil) and Vyvanse (lisdexamfetamine) are widely used for the management of narcolepsy and attention-deficit hyperactivity disorder (ADHD), with ample clinical research indicating their effectiveness over placebo treatments. In certain cases, these drugs may be combined under the close observation of a physician due to potential drug interactions. They operate differently; Nuvigil works by influencing dopamine levels in the brain, whereas Vyvanse is a prodrug converted into dextroamphetamine, an amphetamine salt that increases dopamine and norepinephrine concentrations.
Nuvigil is often considered as a first-line treatment option for sleep disorders like narcolepsy and shift work disorder, while Vyvanse is primarily indicated for ADHD but can also manage binge-eating disorders. Both medications are available in generic forms providing cost benefits especially to patients paying from their pockets.
Like all medications, there might be an adjustment period required for both Nuvigil and Vyvanse before noticeable effects kick in. The side effect profiles of both drugs are somewhat similar; they're generally well-tolerated with common side effects including headache, anxiety or nervousness. However, it's worth noting that given its stimulant nature, Vyvanse might have more pronounced cardiovascular implications compared to Nuvigil.
Patients on either medication must closely monitor any changes in mood or behavior when beginning treatment - immediate medical help should be sought if worsening symptoms or thoughts about self-harm arise.
