Ritalin vs Dexedrine
Introduction
For patients with attention deficit hyperactivity disorder (ADHD) or narcolepsy, certain drugs that alter the concentration of compounds in the brain can help to manage symptoms. Ritalin and Dexedrine are two such drugs. They differ in how they affect neurotransmitters in the brain but both have significant effects on improving focus and reducing impulsivity. Ritalin is a central nervous system stimulant that affects levels of dopamine and norepinephrine by blocking their reuptake into neurons, thereby increasing their concentrations in the synaptic gap to improve attention span and reduce impulsivity. Dexedrine, on the other hand, is an amphetamine which increases levels of dopamine and norepinephrine available for receptors by promoting release from storage sites within neurons as well as inhibiting reuptake.

What is Ritalin?
Methylphenidate (the generic name for Ritalin) was one of the first drugs used in the treatment of attention deficit hyperactivity disorder (ADHD). It was first approved by the FDA in 1955. Ritalin works by increasing levels of dopamine, a neurotransmitter associated with pleasure, movement, and attention. It achieves this effect by blocking the recycling of released dopamine, effectively "trapping" it in the brain for longer periods than usual. This medication is prescribed for both children and adults diagnosed with ADHD. Compared to Dexedrine (Dextroamphetamine), another stimulant medication used to treat ADHD, Ritalin has a more balanced influence on dopamine without substantially affecting other neurotransmitters like norepinephrine that can lead to side effects such as increased heart rate and blood pressure. Therefore, it might have fewer side effects than Dexedrine which has stronger effects on these other neurotransmitters.
What conditions is Ritalin approved to treat?
Ritalin is approved for the treatment of several conditions, including:
- Attention deficit hyperactivity disorder (ADHD)
- Narcolepsy, a sleep disorder that causes excessive daytime drowsiness and sudden attacks of sleep.
Dexedrine is also approved for treatment of these conditions:
- ADHD
- Narcolepsy
Both drugs belong to a class known as stimulants and work by influencing chemicals in the brain related to impulse control and hyperactivity. However, they should be used under medical supervision due to their potential for abuse and dependence.
How does Ritalin help with these illnesses?
Ritalin and Dexedrine are both stimulant medications that help manage symptoms of attention deficit hyperactivity disorder (ADHD) by increasing the amount of dopamine available in the synapses of the brain. Dopamine is a neurotransmitter, a chemical that acts as a messenger in the brain and throughout the body, playing an important role in motivation, reward, reinforcement learning, motor control among other things. These drugs work by blocking dopamine from being reabsorbed by neurons so levels can be maintained higher for longer periods.
It's believed that individuals with ADHD have relatively lower levels of dopamine. Therefore, by increasing this neurotransmitter's level with Ritalin or Dexedrine can limit negative effects associated with ADHD such as difficulty focusing or controlling impulses thus helping patients manage their condition more effectively.
What is Dexedrine?
Dexedrine is a brand name for dextroamphetamine, which is an amphetamine. It functions as a potent central nervous system (CNS) stimulant and sympathomimetic drug by increasing the release of neurotransmitters in your brain called dopamine and norepinephrine, reducing their reabsorption. Additionally, it inhibits monoamine oxidase (MAO), an enzyme that breaks down dopamine and norepinephrine. Dexedrine was first approved by the FDA in 1976.
Unlike Methylphenidate-based medications such as Ritalin, Dexedrine does not exhibit any significant serotonergic activity or inhibit the reuptake of serotonin. This means its side-effect profile can be different from that of SSRI drugs like Prozac—Dexedrine doesn't cause sedation and isn't likely to contribute to weight gain or sexual dysfunction (common side effects with SSRIs).
Its effect on dopamine levels can make it particularly useful for conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy, especially in patients who do not respond well to other treatments.
What conditions is Dexedrine approved to treat?
Dexedrine is a medication that has been approved by the FDA for treatment of the following conditions:
- Attention-deficit/hyperactivity disorder (ADHD)
- Narcolepsy, a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep.
How does Dexedrine help with these illnesses?
Dexedrine is a psychostimulant medication that primarily affects the neurotransmitter dopamine, improving focus and attention while reducing impulsive behavior. It performs an essential role in reward, motivation, and pleasure systems of the brain. Furthermore, it's substantially involved in motor control and decision-making processes. Just as norepinephrine plays a vital role in depression management with Wellbutrin, dopamine impacts ADHD management with Dexedrine. Unlike Ritalin which also affects norepinephrine levels, Dexedrine solely acts on dopamine making it effective for patients who don't respond well to mixed mechanism stimulants like Ritalin or when a more targeted approach is necessary.
How effective are both Ritalin and Dexedrine?
Both methylphenidate (Ritalin) and dextroamphetamine (Dexedrine) are well-established in their efficacy for managing symptoms of Attention Deficit Hyperactivity Disorder (ADHD), with Ritalin first approved by the FDA in 1955 and Dexedrine not long after in 1976. These medications stimulate different neurotransmitters, potentially making one more suitable than the other depending on individual circumstances. A direct comparison of Ritalin and Dexedrine was conducted via a double-blind clinical trial in 2001; both drugs showed comparable effectiveness at alleviating ADHD symptoms along with similar safety profiles.
A review of meta-analyses on Ritalin from 2018 indicated that it can reduce symptoms of ADHD effectively within the first week of treatment, has a favorable side effect profile compared to many other stimulants, and is generally well-tolerated across various age groups including children and adults. This study also noted that Ritalin continues to be one of the most commonly prescribed medications for ADHD worldwide due to its proven track-record over time. The optimal dose is thought to range between 20-60 mg/day, dependent on individual factors.
Similarly, a review published in 2017 demonstrated that Dexedrine is significantly more effective at treating ADHD than placebo treatments, showcasing similar efficiency levels as common alternative stimulant medications. However, despite this evidence supporting its use as an effective stand-alone treatment option for ADHD patients who failed initial treatments or those who experienced adverse effects such as insomnia or reduced appetite from others like SSRIs or SNRIs. Its unique pharmacological properties mean it may be better suited for certain individuals based upon personal health histories.

At what dose is Ritalin typically prescribed?
Oral dosages of Ritalin for adults usually begin at 20–30 mg/day, divided into 2 or 3 doses. For children and adolescents with ADHD, the starting dose is typically 5 mg twice daily (before breakfast and lunch), with gradual increments if necessary. The maximum dosage should not exceed 60 mg/day. On the other hand, Dexedrine is also used to treat ADHD in adults and children. Initial dosing for children over three starts at 2.5 mg daily; it can be increased weekly by up to an additional 2.5mg per day if needed. Adult dosage begins at a total of between five and sixty milligrams taken each day, divided into two or three doses.
At what dose is Dexedrine typically prescribed?
Dexedrine treatment is typically initiated at a dose of 5 mg/day for adults, and can be increased gradually to a maximum of 60 mg/day if required. For children aged six years and older, the starting dose is usually 2.5 mg daily which can then be slowly escalated based on individual response and tolerability to an optimal level. The doses are typically distributed into two or three intakes throughout the day with approximately four to five hours apart between administrations. If there's no significant improvement in symptoms after several weeks at the maximized dosage, consult your healthcare provider as Dexedrine might not be suitable or require further assessment for you.
What are the most common side effects for Ritalin?
Common side effects from Ritalin and Dexedrine can vary, but they may include:
- Nervousness and jitteriness
- Insomnia or other sleep disturbances
- Reduced appetite, which can lead to weight loss

- Increased heart rate or blood pressure
- Dry mouth
- Sweating more than usual
- Mood changes, such as feeling unusually suspicious or distrustful (paranoia)
- Dizziness or a sense of being lightheaded -Numbness in the extremities (fingers and toes)
Please remember that not everyone will experience all these side effects. If you're considering medication for attention deficit hyperactivity disorder (ADHD), discuss potential side effects with your medical provider. It's also important to note that both Ritalin and Dexedrine should be used under the supervision of a healthcare professional due to their risk of dependency and other serious health consequences.
Are there any potential serious side effects for Ritalin?
While Dexedrine and Ritalin are both stimulants used to treat attention deficit hyperactivity disorder (ADHD), they can have different side effects. With Dexedrine, you might experience:
- Increased anxiety or paranoia
- Signs of allergic reaction such as hives, difficulty breathing, swelling in your face or throat

Severe neurological impact could include stiffness high body temperature sweating confusion fast heartbeat shivering twitching nausea vomiting diarrhea.
Always consult with a healthcare provider when experiencing any adverse effects from medication.
What are the most common side effects for Dexedrine?
Dexedrine, a common medication used to treat ADHD and narcolepsy, can have the following side effects:
- Dry mouth or an unpleasant taste in the mouth
- Upset stomach or constipation
- Difficulty falling asleep (insomnia)
- Restlessness or tremors
- Increased heart rate
- Feelings of anxiety or nervousness
- Weight loss due to decreased appetite

In some cases, Dexedrine may also cause blurred vision, increased urination, skin rashes and muscle pain. It's important to note that these side effects usually lessen with continuous use as your body adjusts to the drug. However, if they persist or worsen you should consult with your healthcare provider immediately.
Are there any potential serious side effects for Dexedrine?
While Dexedrine is typically well-tolerated, it can occasionally lead to serious side effects. Potentially concerning symptoms may include:
- Signs of an allergic reaction such as hives, difficulty breathing or swallowing, swelling in your face, lips, tongue or throat
- Mental/mood changes like aggression, agitation and mood swings
- Uncontrolled movements or vocal sounds (tics)
- Circulation problems exemplified by numbness/pain/skin color changes on fingers/toes
- Unusual wounds on fingers or toes
- Chest pain accompanied with a fast/irregular heartbeat If you experience any of these symptoms while taking Dexedrine, discontinue use immediately and consult your healthcare professional.
Contraindications for Ritalin and Dexedrine?
Both Ritalin and Dexedrine, along with most other stimulant medications, may exacerbate symptoms of anxiety or nervousness in some people. If you notice your anxiety increasing, or an increase in restlessness, difficulty sleeping or erratic behavior, please seek immediate medical attention.
Neither Ritalin nor Dexedrine can be taken if you are taking or have been taking monoamine oxidase (MAO) inhibitors (MAOIs). Always tell your physician which medications you are taking; MAOIs will require a period of about 2 weeks to clear from the system to prevent dangerous interactions with Ritalin and Dexedrine. Stimulants such as these may also have serious cardiovascular side effects for those with pre-existing heart conditions.
How much do Ritalin and Dexedrine cost?
For the brand name versions of these drugs:
- The price for 60 tablets of Ritalin (10 mg) averages around $400, which works out to about $13-$26/day, depending on your dose.
- The cost for 30 capsules of Dexedrine (15 mg) is approximately $300, translating to roughly $10/day.
Thus, if you are in a higher dosage range for Ritalin (i.e., 20 mg/day or higher), then brand-name Dexedrine might be less expensive on a per-day treatment basis. Please remember that cost should not be the sole factor when deciding between these medications.
The costs for generic versions of Ritalin (methylphenidate) and Dexedrine (dextroamphetamine) are significantly lower:
- Methylphenidate comes in packs ranging from 30–90 tablets with prices starting as low as $0.50 up to around $1.50 per day based on typical dosages from 20mg to 60mg/day.
- Dextroamphetamine is available in quantities ranging from 15 up to several hundred capsules with daily costs starting as low as about $.40 and not exceeding approximately $.80 even at higher doses.
Popularity of Ritalin and Dexedrine
Methylphenidate, also known as Ritalin in its brand form, was estimated to have been prescribed to about 2.4 million people in the US in 2020. Methylphenidate accounted for just over 17% of prescriptions for ADHD medications in the US last year. It's part of a broader class of stimulant drugs used primarily to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.
Dextroamphetamine, including brand versions such as Dexedrine, was prescribed to approximately 610,000 individuals in the USA during the same period. In terms of overall ADHD medication prescriptions within America, dextroamphetamine accounts for around 5%. Both these prescription figures have remained relatively steady over the past decade with minor fluctuations due to variations like doctor preferences and patient response rates.
Conclusion
Both Ritalin (methylphenidate) and Dexedrine (dextroamphetamine) are well-established medications used in the management of attention deficit hyperactivity disorder (ADHD), and their effectiveness is supported by a wealth of clinical studies. Both drugs may sometimes be used together, but this requires careful physician oversight due to potential interactions between them. Their mechanisms of action differ, with Ritalin primarily inhibiting the reuptake of dopamine and norepinephrine, while Dexedrine promotes the release of these neurotransmitters into the synaptic cleft.
Ritalin is often considered a first-line treatment for ADHD, whereas Dexedrine might be added to therapy or chosen as an alternative if patients do not respond adequately to initial medication like Ritalin or have specific needs that make it preferable.
Both drugs are available as generics which can significantly reduce cost burden for patients who pay out-of-pocket. However, both Ritalin and Dexedrine may require some time before full benefits become apparent.
The side effect profiles are somewhat similar between these two stimulants: both can cause insomnia, decreased appetite, weight loss among other effects with high doses possibly leading to more serious adverse events. But each individual's response can vary widely so monitoring is crucial when starting either drug - immediate medical help should be sought if any worrying symptoms arise such as chest pain or signs of mental health problems.
