Vyvanse vs Ritalin
Introduction
For patients diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) or narcolepsy, certain drugs that alter the concentrations of neurotransmitters in the brain can help manage symptoms and improve focus. Vyvanse and Ritalin are two such drugs prescribed for these conditions. They each impact different neurotransmitters in the brain but both have effects on attention span and impulse control in patients with ADHD.
Vyvanse is a prodrug of dextroamphetamine, which means it's inactive until metabolised by body enzymes. It works primarily by increasing levels of dopamine and norepinephrine between synapses in the brain to enhance concentration.
Ritalin, on the other hand, is a methylphenidate drug acting as a reuptake inhibitor for dopamine and norepinephrine neurotransmitters; this makes these chemicals more available within one's neuronal synapse to improve attention span.

What is Vyvanse?
Lisdexamfetamine (the generic name for Vyvanse) was a significant development in the class of drugs known as stimulant medications, similar to methylphenidate (Ritalin). Lisdexamfetamine was first approved by the FDA in 2007 and is used primarily for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and binge eating disorder. Vyvanse works by enhancing levels of dopamine and norepinephrine in the brain, thereby improving focus, attention, and impulse control. Unlike Ritalin which has an immediate effect after ingestion, Vyvanse has a prodrug delivery system; this means it becomes active only after it is broken down in the body resulting in more steady therapeutic effects throughout the day with less potential for abuse due to its slower onset of action. While both drugs can cause side effects like nervousness or insomnia, those taking Vyvanse may experience fewer instances because of its gradual release mechanism.
What conditions is Vyvanse approved to treat?
Vyvanse is approved for the treatment of certain neuropsychiatric conditions including:
- Attention Deficit Hyperactivity Disorder (ADHD) in both adults and children aged 6 to 12 years
- Moderate to Severe Binge Eating Disorder (BED) in adults
Ritalin, on the other hand, is primarily used for:
- Treatment of ADHD
- Narcolepsy, a condition characterized by excessive sleepiness or sudden attacks of daytime sleep.
How does Vyvanse help with these illnesses?
Vyvanse is a medication that helps manage Attention Deficit Hyperactivity Disorder (ADHD) by increasing the amount of dopamine and norepinephrine in your brain. This medication works by preventing these neurotransmitters from being reabsorbed into your neurons, which allows them to remain at higher levels for extended periods of time. Dopamine and norepinephrine are neurochemicals that play vital roles in attention span, focus, impulse control, and mood stability among other functions. It's believed individuals with ADHD have relatively lower levels of these chemicals. Therefore, by increasing their presence in the brain, Vyvanse can limit the negative effects associated with ADHD allowing patients to improve their ability to pay attention and stay focused.
Ritalin also increases dopamine levels but does so more quickly than Vyvanse resulting in a faster onset of action but shorter duration effect. The choice between Ritalin and Vyvanse often depends on individual patient needs including symptom severity throughout the day or potential side effects like sleep disturbance due to late-day dosing.
What is Ritalin?
Ritalin is a brand name for methylphenidate, which is a psychostimulant drug used primarily to treat attention deficit hyperactivity disorder (ADHD). Ritalin works by increasing the levels of dopamine and norepinephrine in the brain. This occurs because it partially blocks the reuptake of these neurotransmitters, allowing them to accumulate and prolong their effects. Ritalin was first approved by the FDA in 1955.
Unlike Vyvanse, another ADHD treatment, Ritalin does not need to be metabolized or broken down in the body before its active ingredient starts working. This means that its effects are typically felt within twenty minutes after taking it orally.
Its side-effect profile differs from drugs like Vyvanse as well; common side-effects include nervousness and insomnia. It's also worth noting that while both medications can be effective for treating ADHD symptoms, they may work better or worse depending on individual patient characteristics.
What conditions is Ritalin approved to treat?
Ritalin is an FDA-approved medication used in the treatment of:
- Attention Deficit Hyperactivity Disorder (ADHD)
- Narcolepsy, a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep.
How does Ritalin help with these illnesses?
Dopamine is a neurotransmitter that plays several important roles in the brain and body. It is involved in reward, motivation, memory, attention and even regulating body movements. Ritalin works by increasing the levels of dopamine available to your brain cells, thereby enhancing focus and attention for individuals with conditions like ADHD. This medication acts on the dopamine transporter protein, blocking the reuptake of dopamine into neurons which allows more to remain active within the synaptic space between nerve cells. In contrast to Vyvanse – another stimulant used for treating ADHD – Ritalin has a faster onset of action but shorter duration of effect. Hence it may be chosen when immediate symptom control is required or can be combined with longer-acting drugs in certain treatment plans.
How effective are both Vyvanse and Ritalin?
Both lisdexamfetamine (Vyvanse) and methylphenidate (Ritalin) have well-established histories of success in treating patients with attention deficit hyperactivity disorder (ADHD), having been approved by the FDA in 2007 and 1955, respectively. Since they work on different neurotransmitters, they may be prescribed under different circumstances. The effectiveness of Vyvanse and Ritalin at managing ADHD symptoms was analyzed in a double-blind clinical trial in 2014; both medications showed comparable efficacy for managing symptoms as well as similar safety profiles. In this study, there were no significant differences between the groups receiving Vyvanse or Ritalin regarding improvements on standard rating scales for ADHD.
A meta-analysis conducted in 2018 demonstrated that Vyvanse is effective from the first dose onwards at reducing core symptoms of ADHD, has fewer rebound symptoms compared to other amphetamine-based treatments due to its prodrug formulation, and is generally well-tolerated by most patient populations including children aged six years or older. More importantly, it has become one of the most widely prescribed drugs for treating ADHD worldwide due to its once-daily dosing regimen which improves adherence rates among patients.
On the other hand, another review published in 2016 indicated that while Ritalin seems more effective than placebo at controlling short-term symptoms of ADHD, it appears less consistently effective over longer periods compared to newer stimulant medications like Vyvanase. Nonetheless,Ritalin remains a first-line treatment option for many because it's been extensively studied over several decades providing a wealth of data about its efficacy and safety profile. Despite being around longer than any other medication used specifically for ADHD treatment , evidence supporting Ritalin as significantly augmenting effects when co-prescribed with non-stimulants is lacking . However due to its unique pharmacology ,Ritalin could be an optimal choice particularly for those who did not respond favourably towards amphetamines -based therapy or have particular need to avoid common side effects associated with them such as prolonged loss off appetite.

At what dose is Vyvanse typically prescribed?
Oral dosages of Vyvanse range from 30-70 mg/day, but studies have indicated that 30 mg/day is sufficient for treating Attention Deficit Hyperactivity Disorder (ADHD) in most people. Children and adolescents may be started on a lower dose of around 20 mg/day. In either population, the dosage can be increased after one week if there is no response or if symptoms persist. The maximum dosage that should not be exceeded in any case is 70 mg/day when taken orally.
On the other hand, oral dosages of Ritalin for adults typically start at around 20–30 mg per day, divided into two or three doses. For children ages six and above who are just starting treatment, it's common to begin with a low dose such as 5mg once or twice daily and gradually increase as needed each week by increments of five to ten milligrams. Maximum recommended daily dosage usually doesn't exceed 60mg although some cases might require higher doses.
At what dose is Ritalin typically prescribed?
Ritalin therapy is typically initiated at a dosage of 5-20mg per day. The dose can then be increased to 60 mg/day, distributed into two or three doses, with intervals of around 4 hours apart. The highest dose is usually capped at 60 mg/day segregated into multiple doses and may be explored if there isn't any response to the treatment after several weeks at a lower dosage. Be aware that Ritalin should not be taken later in the day as it could interfere with sleep patterns due to its stimulant effects.
What are the most common side effects for Vyvanse?
While both Vyvanse and Ritalin are used to treat Attention Deficit Hyperactivity Disorder (ADHD), they each have unique side effects.
Common side effects of Vyvanse include:
- Anxiety
- Decreased appetite
- Diarrhea
- Dizziness
- Dry mouth
- Irritability
- Loss of appetite, weight loss

-Decreased appetite which may lead to weight loss.
-Nausea, stomach pain, and vomiting.
-Dizziness or lightheadedness.
-Sweating a lot more than usual.
It is important to consult with your healthcare provider about any potential side effects before starting these medications.
Are there any potential serious side effects for Vyvanse?
While both Vyvanse and Ritalin are commonly prescribed medications for ADHD, they can cause serious side effects in rare cases:
- Suicidal thoughts or actions
- Signs of a severe allergic reaction: hives; trouble breathing; swelling of your face, lips, tongue, or throat
- Heart-related problems: chest pain, trouble breathing, feeling like you might pass out
- Circulation problems: numbness, pain, cold feeling in your hands or feet (even with warm weather), unexplained wounds on fingers and toes
- Mental health issues such as new behavior problems including aggression or paranoia; new bipolar illness signs; worsening symptoms of anxiety.
Vyvanse-specific potential risks include blurred vision and serotonin syndrome - an excess of serotonin that causes agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea.
If any of these symptoms occur while taking either medication it's important to seek immediate medical attention.
What are the most common side effects for Ritalin?
Ritalin, another medication prescribed for attention deficit hyperactivity disorder (ADHD), can lead to a range of side effects. These might include:
- Nervousness or anxiety
- Insomnia and other sleep disturbances
- Decreased appetite leading to weight loss
- Abdominal pain or nausea
- Headaches or dizziness
- Increased blood pressure and faster heartbeat
- Dry mouth or an unpleasant taste in the mouth
- Sweating excessively
- Vision problems such as blurred vision.
Less common but more serious side effects may involve confusion, agitation, and rash. It's also worth noting that Ritalin could cause joint or muscle pain. Just like any other medication, it is crucial to monitor your body's response when taking Ritalin and seek medical advice if you experience any discomforting symptoms.
Are there any potential serious side effects for Ritalin?
When consuming Ritalin, one should be vigilant for any signs of adverse reactions or side effects. These can include:
- Signs of an allergic reaction such as hives, itching, fever, swollen glands; difficulty breathing; swelling in your face or throat.
- Mental health changes including new or worsening behavior and thought problems or new manic episodes.
- Chest pain, shortness of breath, heart palpitations which may suggest cardiovascular complications.
- Neurological issues like dizziness; trouble speaking; numbness in certain parts of the body suggesting possible stroke symptoms.
- Visual disturbances such as blurred vision and difficulties focusing.
- Increased blood pressure - severe headache, blurred vision pounding in your neck or ears.
If you experience any of these symptoms while taking Ritalin, it is recommended that you seek immediate medical attention.
Contraindications for Vyvanse and Ritalin?
Both Vyvanse and Ritalin, along with most other stimulant medications, may increase anxiety or agitation in some individuals. If you notice your anxiety worsening, or an increase in panic attacks or aggressive behavior while on these drugs, please seek immediate medical attention.
Neither Vyvanse nor Ritalin should be taken if you are taking, or have recently been taking monoamine oxidase (MAO) inhibitors. Always inform your physician about all the medications you are currently using; MAOIs will require a period of about two weeks to clear from your system to prevent dangerous interactions with Vyvanse and Ritalin.
How much do Vyvanse and Ritalin cost?
For the brand name versions of these drugs:
- The price for 30 capsules of Vyvanse (40 mg) averages around $330, working out to approximately $11/day.
- The price for 60 tablets of Ritalin (20 mg) is about $85, which works out to roughly $1.42 per day.
Thus, if you are on a higher dosage range for Vyvanse (i.e., 70 mg/day), then brand-name Ritalin is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions also known as lisdexamfetamine and methylphenidate respectively, costs are significantly lower:
- Lisdexamfetamine (30 capsules of 40mg) will cost between $200-$250 depending upon your location and pharmacy used, this translates to an average daily expense from approximately $6.67 -8.33.
- Methylphenidate comes in packs ranging from 100 up to 500 tablets with prices starting from as low as $.25/day when bought in larger quantities upfront and not exceeding about $.50/day even at greater dosages.
Popularity of Vyvanse and Ritalin
Lisdexamfetamine dimesylate, sold under the brand name Vyvanse among others, was estimated to have been prescribed to about 3.7 million people in the US in 2020. Vyvanse accounted for just over 15% of prescriptions for attention deficit hyperactivity disorder (ADHD) medications in the US. However, it appears to be most common among "prodrug" stimulants (medications that are inactive until metabolized by the body). The prevalence of Vyvanse has generally increased since its approval by FDA in 2008.
Methylphenidate, including brand versions such as Ritalin, was prescribed to approximately 5 million people in the USA during 2020. In terms of ADHD treatments within the US market, methylphenidate accounts for roughly a quarter of all prescriptions and is one of the longest-used drugs for this condition. Despite newer alternatives entering the market, usage rates for methylphenidate-based medications like Ritalin have remained relatively stable over recent years due to their established efficacy record and wider age group approval.
Conclusion
Both Vyvanse (lisdexamfetamine) and Ritalin (methylphenidate) have demonstrated efficacy in treating Attention Deficit Hyperactivity Disorder (ADHD), with numerous clinical studies and meta-analyses supporting their effectiveness over placebo treatments. Sometimes, these drugs may be used in combination under careful physician guidance due to potential interactions. They exhibit different mechanisms of action: Vyvanse is a prodrug converted into active dextroamphetamine in the body, while Ritalin acts by blocking the reuptake of dopamine and norepinephrine.
Vyvanse is typically considered as a first-line treatment option for ADHD given its longer duration of effect lasting up to 14 hours, whereas Ritalin is often administered multiple times per day due to its shorter half-life. It can also be an adjuvant therapy when patients don't respond well to initial treatment or need avoidance of certain side effects.
Both medications are available in generic form which provides significant cost savings especially for out-of-pocket payments. Both Vyvanse and Ritalin require an adjustment period where therapeutic effects might not be immediately noticeable.
Side effects between the two drugs are similar but generally well-tolerated; however, Vyvanse tends to have fewer reports on appetite suppression compared to Ritalin. For both medications, it's crucial that patients closely monitor their responses when starting therapy and seek immediate medical help if they notice worsening symptoms or develop new psychiatric signs such as hallucinations or suicidal thoughts.
