Adderall Dosage Chart: Recommended Dosage for Adults

There are many different Adderall dosages, and taking too much can lead to risky side effects. Learn more about what Adderall is used for and how much is typically prescribed.

When looking at Adderall dosage, there are distinctions between extended-release and immediate-release options. The Adderall dosage instructions are different for the two.

Article at a Glance:

  • Adderall immediate-release works within 15-30 minutes and lasts 4-6 hours.
  • Adderall extended-release works within 30-60 minutes and lasts for 10-12 hours.
  • The adult Adderall immediate-release dosage is 5 mg to 40 mg per day, spread throughout the day.
  • Adderall extended-release is taken in one daily dose, usually not to exceed 40 mg per day.
  • It is very dangerous (and even potentially fatal) to use high dosages of Adderall to get high.

Adderall Dosage Guide/Chart

If you’re searching for an Adderall dosage chart, the following infographic provides a general overview of what an Adderall dosage might look like.

What Dosage Does Adderall Come In?

Adderall XR dosage begins at 5 mg. Then there are 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg dosages.

The Adderall IR dosage options start at 5 mg and include 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg. There is more flexibility in immediate-release dosages, allowing doctors to start patients out on a minimal dose and increase it incrementally.

Doctors will usually start an Adderall dosage at the smallest amount that may potentially work and then gradually increase it. For ADHD, the immediate-release dosage for adults is between 5 mg to 40 mg a day. The dosage is divided throughout the day.

In regards to ADHD, doses of more than 40 mg a day are rarely more effective than lower amounts. For narcolepsy treatment, doctors may begin with 5 mg a day and then go up to 60 mg a day, with dosages given every four to six hours.

With Adderall XR, one dose is taken daily instead of in divided doses. A doctor may still recommend that the extended-release dosage not exceed 40 mg a day.

How Long Does Adderall & Adderall XR Work?

Adderall immediate-release (IR) starts working within 15 to 30 minutes and lasts for about 4 to 6 hours. Adderall extended-release (XR) can take about 30 to 60 minutes to start working, and it lasts for around 10 to 12 hours. Both IR and XR can lead to a crash as someone comes down from the effects of the drug, but XR tends to have less noticeable effects.

Avoiding an Adderall Dosage High

Trying to abuse Adderall to get high is very dangerous. At higher doses, it can be associated with sudden death. Determining how much Adderall would get someone high is almost impossible, as different people will have different reactions. Some people get high from Adderall by crushing and snorting it or dissolving and injecting it. These methods make the risks even greater.

It’s possible to experience a fatal dose when using Adderall to get high, so this should be avoided. People should never take Adderall without a prescription from their doctor. If they do have a prescription, it should only be used as directed.

If you or a loved one is struggling with Adderall misuse, The Recovery Village is here to help. We encourage you to learn more about treatment plans and programs that can work well for your situation.

Similarities, Uses, Mixing & Weight Loss Risks

There are many ways to compare Adderall vs. Vyvanse, and two important factors to compare are dosage and what mental health disorders they’re prescribed for as well as common reasons for abuse, including weight loss.

Article at a Glance:  

  • Adderall and Vyvanse are commonly prescribed to treat ADHD.  
  • The recommended Adderall dosage is 2.5 to 60 mg per day, while the dosage for Vyvanse is 30 mg daily. 
  • Both Adderall and Vyvanse can suppress the appetite but should not be used for weight loss.  
  • Adderall and Vyvanse should not generally be used together because of the increased risk of side effects.   
  • Both Adderall and Vyvance use can lead to abuse, addiction, and physical dependence.  

Common Uses for Adderall and Vyvanse

Adderall is a combination drug that includes levoamphetamine and dextroamphetamine. It’s part of a class of drugs known as stimulants. Vyvanse, which has the generic name lisdexamfetamine, is also a stimulant of the central nervous system. Both are commonly prescribed to treat ADHD.

Less frequently, Adderall may be prescribed to treat narcolepsy and, in some cases, Vyvanse may be used as a medication to treat binge eating disorders. However, Vyvanse is supposed to be used as part of a full treatment plan that includes psychological and social elements.

Both Adderall and Vyvanse can contribute to abuse and addiction, as well as physical dependence. The side effects are very similar as well and include anxiety, insomnia, and decreased appetite.

If you or someone you know struggles with an eating disorder, treatment is available. For immediate assistance or help in evaluating your options, you can contact the National Eating Disorder Association by visiting them online or by calling (800) 931-2237.

There are many ways to compare Adderall and Vyvanse, and one important factor to compare is dosage.

Patients are usually prescribed to take Adderall once or twice a day. The recommended dosage can vary from 2.5 to 60 mg a day. Different prescribed doses are based on the age and individual needs of the patient.

Related Topic: Adderall Dosage Guide

The recommended beginning dose for treating ADHD in adults with Vyvanse is 30 mg. For pediatric patients, the starting dose is usually 20 to 30 mg taken once daily in the morning. The maximum dose of Vyvanse is 70 mg a day, and a doctor may increase the dose by 10 to 20 mg a day, at weekly intervals. For treating a binge eating disorder with Vyvanse, the recommended dose in adults is 50 to 70 mg a day.

Side Effects & Weight Loss Risks from Prolonged Adderall or Vyvanse Use

Using Adderall or Vyvanse for weight loss isn’t an approved use. It’s considered a possible side effect, although Vyvanse can be used to treat symptoms of binge eating disorder.

Amphetamines like Adderall can lead to weight loss. Vyvanse acts similarly to an amphetamine. These drugs release certain brain chemicals that can increase energy and suppress appetite. In some cases, they can also increase metabolism levels.

Both tend to have similar weight loss results, but with Adderall people may experience rebound hunger after the effects of the drug wear off. Regardless of whether you consider Adderall or Vyvanse for weight loss, they’re not healthy or sustainable options.

When the effects of either medicine wear off, so does the appetite suppression. Your body also quickly adjusts to the medicine’s effects, so you may no longer experience appetite suppression after a short period of taking them. This makes the weight loss effects both short-lived and unsustainable for most people. With either medication, your body usually adjusts to the effects, making them ineffective and impractical for a weight loss goal.

What’s more, when you’re withdrawing from amphetamines, the result is an increased appetite. If you use either of these drugs as a way to lose weight and you stop, you will have more problems controlling your appetite than you did before.

Are Adderall & Vyvanse Safe to Use Together?

Considering the similarities between the two, people may wonder if Adderall and Vyvanse can be taken together. The answer is usually no.  When you combine the two stimulants together, it increases your risk of side effects.

For example, you may have extreme changes in mood, intense anxiety, or severe insomnia. Combining multiple stimulants as such can affect your central nervous system and create problems like elevated blood pressure, high body temperature, and cardiovascular problems.

Finally, when people are coming down off Adderall or Vyvanse, it can cause them to feel depressed or have sudden shifts in mood. If you take them together, this can be worse.

Do we need a magic pill to improve memory and attention?

Nootropics, drugs that claim to improve mental performance and performance, are gaining popularity. But are they really effective? And what will happen if everyone starts using them?

Honoré de Balzac was an avid coffee drinker who believed that coffee was the best way to stimulate the brain. Every evening he went in search of night coffee shops, and then wrote until morning.

It is said that he drank 50 cups of his favorite drink daily. And ... he literally swallowed ground coffee with spoons - it "worked" well on an empty stomach.

The writer said that after a sip of coffee powder "the ideas in my head began to march briskly, like battalions of a great army that go to the battlefield to rush into battle. "

Obviously it really helped. Balzac was an incredibly prolific writer, writing almost a hundred novels, short stories and plays. True, he died of heart failure at the age of only 51 years.

Caption before photo,

Honore de Balzac was one of the first proponents of nootropics - to stimulate creativity, he consumed huge amounts of caffeine daily

For centuries, the only help in overcoming the mountain of boring and painstaking work was caffeine .

And only the last generation of workers began to experiment with substances that, in their opinion, increase intellectual abilities and contribute to fantastic performance.

In fact, some of these "smart drags" ("mind pills") are already quite popular. A recent survey of tens of thousands of Americans found that 30% of them had taken such drugs within the past year.

Perhaps soon we will start doing all this.

But what will be the consequences? Will a new generation of giants of thought appear, whose brilliant inventions will mark the space age of mankind? Will we achieve insane economic growth? Or maybe the working week will become noticeably shorter, because people will work more efficiently?

"Changes the mind"

To answer these questions, we first need to figure out what scientists are offering us.

The first drug of this group, piracetam, was synthesized in the early 1960s by the Romanian chemist and psychologist Corneliu George. He was looking for a substance that would cause drowsiness, and after a few months he came up with the drug Compound 6215.

It was safe, but there was no sedative effect either. It seemed to be the other way around. In patients who took it for a month, memory improved significantly.

  • Legalization of marijuana - a headache for employers?
  • The LSD cult that transformed America
  • What to eat for clarity of thought and good memory
  • Coffee and cigars: what is known about the main defendant in the "cocaine case"?
  • Coffee does more good than harm

George immediately realized the significance of his invention and coined the term "nootropic" - a combination of the Greek words νους ("mind") and τροπή ("turning, hindering, changing").

Today piracetam is a favorite "magic pill" of students and young professionals who seek to improve their performance. Although several decades after the invention of the drug, there is no sufficient evidence of its effectiveness.

In the UK, Piracetam is available by prescription only, although the US Food and Drug Administration has not approved Piracetam and has not allowed Piracetam to be sold as a dietary supplement.

Texas entrepreneur and podcast author Mansal Denton takes phenylpiracetam, a close analogue of piracetam developed in the Soviet Union to help astronauts cope with the stresses of space life.

Creatine has always been the main element of bodybuilders dietary supplements, but now it is used to improve mental activity of

"When I use this drug, I improve speech skills, and therefore I usually record many podcasts on such days," he says.

In fact, this effect is quite typical for nootropics. Despite the abundance of their passionate fans, the intellectual effect is almost invisible or completely absent.

take, for example, Monogratitza Celebrates. This white powder dietary supplement is usually mixed with sugary drinks or milkshakes, or taken as a tablet.

The substance enters the brain, and recent research shows that creatine does improve working memory and intelligence.

Although creatine was discovered relatively recently by ambitious young professionals, it has been known to bodybuilders for decades. The substance is the main element of many dietary supplements, and in the US, sports supplements are a multi-billion dollar industry.

In a survey last year by Ipsos Public Affairs, 22% of adults said they had used a dietary supplement in the past year.

If creatine had a serious effect on human performance, we would certainly notice it.

Of course, there are drugs with a stronger effect.

"Some of them are quite effective," says Andrew Huberman, a neuroscientist at Stanford University.

There is one category of nootropics that scientists and biohackers (amateurs who try to change the physiology of their body at the molecular level) are very interested in.

These are psychostimulants.

The most common of these are amphetamines and methylphenidate, which are sold by prescription under the brand names Adderall and Ritalin.

In the United States, both drugs are approved for the treatment of people with Attention Deficit Hyperactivity Disorder.

But now they are often abused by people whose work requires a high concentration of attention.

Image caption,

Ritalin is a psychostimulant designed to treat attention deficit hyperactivity disorder, but is often used simply to improve attention.

Amphetamines have long established themselves as nootropics.

This feature was well known to the legendary Hungarian mathematician Pal Erdős, who with the help of amphetamines withstood 19-hour mathematical sessions.

Writer Graham Greene used them to write two books at the same time. Today, their use is quite common among journalists, creative professionals and financiers.

Those who took them swear that they really change consciousness, although not in the way you expected.

Back in 2015, a scientific review showed that the effect of amphetamines on intelligence is quite "modest". But most people use them to improve their mental abilities, but rather to increase energy and motivation to work.

(Both drugs have serious side effects, more on that later).

One of the effects of psychostimulants like Adderall and Ritalin is to make it easier to perform psychologically exhausting tasks.

One study showed that math problems seemed more interesting under the influence of Ritalin.

Assuming that all people start using mental stimulants, we will have at least two main consequences.

First, people will stop avoiding unpleasant tasks.

Tired office workers who have perfected the art of idleness in the workplace for years will frantically sort through documents, update spreadsheets and enthusiastically attend boring meetings.

  • How to prevent employees from "surfing the Internet" during working hours
  • What gives us the ability to think flexibly
  • One simple trick to improve memory
  • The withdrawal syndrome: a mysterious disease in Sweden grow rapidly. This side effect of nootropics has been talked about for quite some time.

    But whether this is so good is a debatable question.

    "Many Silicon Valley and Wall Street professionals are already using mental stimulants. It's starting to feel like a professional mental sport where the stakes and competition are increasing daily," said Jeffrey Wu, CEO and co-founder of HVMN, which makes a line of nootropic supplements. .

    But there are significant drawbacks in this. Amphetamines are structurally similar to methamphetamine, a powerful addictive drug that has ruined countless lives. It can also have fatal consequences.

    There are many reports that Adderall and Ritalin are addictive. And they also have a number of side effects, such as nervousness, anxiety, insomnia, stomach pain, and even hair loss.

    Finally, psychostimulants are unlikely to increase productivity in general.

    An important question, how will a person feel the next day? You can work at your peak for 12 hours, but then for a day or two you will feel a strong decline in activity.

    However, we still have a few proven options that can be bought without a prescription in every coffee shop.

    This is, first of all, coffee. Unfortunately, no one has yet calculated the impact of caffeine on economic growth, but many other studies have found many of its benefits.

    Image copyright, Getty Images

    Image caption,

    Coffee still seems to be the best stimulant of intellectual activity

    Interestingly, caffeine turned out to be more effective than a commercial caffeine-based supplement produced by Woo, which now costs 17.9$5 for 60 tablets.

    Well, and secondly, nicotine. Scientists are increasingly realizing that it has a powerful nootropic effect that improves a person's memory and helps focus.

    Although the risks and side effects are well known to everyone.

    "Some well-known neuroscientists chew Nicorette to improve their mental alertness. But they've all smoked in the past, so it's probably a replacement for a bad habit," Huberman notes.
