Adderall is a popular medication to treat attention-deficit hyperactivity disorder and narcolepsy in adults and children. It includes amphetamine and dextroamphetamine, two stimulant compounds that work to improve focus, attention, and impulse control.
Doctors prescribe it in different key dosages —10 mg, 20 mg, and 30 mg—depending on a person’s needs.
Here is all the information on Adderall dosages. We explain how each dosage works, who should use it, and what to keep in mind before taking it.

What is Adderall — IR vs. XR?
There are two types of Adderall:
- Immediate Release (IR)
- Extended Release (XR)
The primary difference is in the onset and duration of the effects,
Adderall IR acts quickly, within 30 to 60 minutes. Its effects last approximately 4 to 6 hours, and it is commonly used several times per day.
Adderall XR has an extended release and is effective up to 12 hours. It is usually taken once daily in the morning.
How Release Mechanisms Affect Dosage
The way each type delivers its ingredients affects how often it’s used:
- IR gets into the system quicker and wears off faster, so doctors may recommend splitting the total daily amount into smaller portions.
- XR has a longer duration of action, meaning it is typically a morning dose that covers the day.
Some people have found that their IR responds better because it gives more control over the timing. Others like XR because it eliminates pill burden.
Adderall Dosages of 10mg, 20mg, and 30mg
However, the first thing to understand is that Adderall dosages vary to meet the individual need. The tablets are available in 10mg, 20mg and 30mg strengths. The appropriate dose varies based on factors like age, severity of symptoms and individual response to the treatment. It’s best to start at the lowest effective dose and titrate up as needed with medical supervision.
20mg once daily is considered the typical starting dose of Adderall XR in adults. This can be changed depending on how effective it is and any side effects. If lower doses aren’t effective, higher doses—such as 30mg—could be considered, but should be done cautiously and with a doctor’s supervision.
It’s important to follow a healthcare provider’s instructions when taking Adderall. So, they will want to take a fair-by-fair look and decide what is the right dosage and keep an eye out for potential side effects.
However, here are the recommended doses for adults and children……
Dosage Guidelines for Adults with ADHD
- Initial dose: 5 mg given once or twice daily (IR) or 20 mg given once daily (XR)
- Adjustment: Gradually increased by 5mg weekly until symptoms were improved
- Maximum Dosage: 40mg/day (most cases)
- Switching to XR? A single XR dose can be derived from equivalent IR doses.
Doctors adjust doses according to how patients respond and side effects.
Dosage Guidelines for Children with ADHD
Ages 6-12:
- Start with 5mg IR once or twice daily.
- May increase 5mg each week as necessary.
- Max dose: 30mg/day.
Ages 13-17:
- Start with 10mg XR in the morning.
- Can be increased up to 20mg XR after 1 week.
It is rare for younger children to receive doses greater than 30mg/day.
Elements Determining Adderall Dosage
- Metabolism: The way people metabolize medications varies, which has an impact on how long Adderall remains in the system.
- Severity of Symptoms: More severe symptoms may necessitate increased dosages for adequate control.
- Co-existing Conditions: Other medical conditions might affect how well or how safely Adderall works.
- Other Medicines: Interactions with other drugs may require dose adjustments.
Main Considerations When Taking Adderall
1. Timings
- Morning Doses: Adderall is most effective when taken in the morning. Taking it too late can make it hard to sleep.
- Consistent Schedule: If you take Adderall at the same time every day, you will get the same effect.
2. With or Without Food?
- Immediate-Release (IR): May be taken with or without food, although absorption may be delayed by high-fat meals.
- Extended-Release (XR): Works best when taken with no food or just a light meal to allow for even absorption.
3. Swallowing Guidelines
- Swallowing Capsules: Swallow Adderall XR capsules whole with water or other liquids.
- For Those Who Can’t Swallow Pills: If swallowing capsules is difficult, you can open the Adderall XR capsule and sprinkle the medicine over a spoonful of applesauce. Swallow the mixture without chewing, followed by a drink of water or other liquid.
What If I Miss a Dose or Overdose?
Missed Dose
IR Version: Take the missed dose as soon as it’s remembered, but skip it if it’s late in the day.
XR Version: If you miss your morning dose, take it if it’s the same day. Do not assign it in the afternoon.
Overdose Symptoms
- Mild Symptoms: Headache, nausea, restlessness.
- Severe Signs: Fast heart rate, confusion, hallucinations, seizures.
What to Do
If signs of overdose occur, call emergency services right away.
Who Should Avoid Adderall?
Adderall isn’t safe for all people. You should not take it if you have:
- Heart disease, hypertension, or a past history of stroke
- Severe anxiety or bipolar disorder
- A history of drug abuse or addiction
- Taken an MAOI antidepressant in the past 14 days
Common Side Effects
- Loss of appetite
- Insomnia
- Dry mouth
- Headache
- Nausea
Severe Side Effects (Seek Medical Attention)
- Fast or irregular heartbeat
- Shortness of breath
- Severe mood swings or hallucinations
Long-Term Considerations and Monitoring
Risk of Tolerance and Dependence
- Long-term use may lead to tolerance, requiring higher doses for the same effect.
- Some people develop dependence, especially with misuse.
Monitoring for Safety
- Routine doctor visits allow monitoring of progress and dosing adjustments.
- Adults are particularly advised to get routine heart checkups.
Impact on Growth (In Children)
There are some studies of Adderall that suggest it might slow growth in children, but regular monitoring for growth helps deal with this.
Risks to Heart Health (In Adults)
Regular checkups are especially important because long-term use can affect blood pressure and heart rate.
Alternatives to Adderall
Adderall is a well-known ADHD medication, but it’s not the only option. Some people experience side effects, while others prefer non-stimulant treatments. Below are alternative medications and lifestyle changes that can help manage ADHD symptoms.
Non-Stimulant Medications
Atomoxetine (Strattera)
- Increases norepinephrine levels to improve focus.
- Lower risk of abuse compared to stimulants.
- Possible side effects: stomach upset, fatigue, mood swings.
Guanfacine (Intuniv) & Clonidine (Kapvay)
- Originally used for blood pressure, these help with impulsivity and hyperactivity.
- May cause drowsiness and low blood pressure.
Bupropion (Wellbutrin)
- An antidepressant that also helps with ADHD symptoms.
- Can improve mood and focus but may cause dry mouth and headaches.
Comparison of Non-Stimulants with Adderall
| Feature | Adderall (Stimulant) | Non-Stimulants |
| Effect Speed | Works within hours | Takes weeks to show results |
| Abuse Risk | Higher | Low |
| Side Effects | Insomnia, appetite loss | Fatigue, dizziness |
| Best For | Immediate symptom relief | People with anxiety or heart issues |
Lifestyle Modifications
Medication is not the only option for managing ADHD. These strategies work for many people:
- Behavioral Therapy – Assists the child in the development of skills such as time management and organization.
- Diet & Nutrition—Eating omega-3s, protein-rich foods, and whole grains bolsters brain function.
- Exercise—Regular exercise can increase focus and decrease hyperactivity.
- Sleep Hygiene—Good sleep routines can help minimize ADHD symptoms.
Holistic Approaches
- Mindfulness & Meditation—Enhances self-control and focus.
- Neurofeedback—Assists in brain activity balancing, but studies are yet to be developed.
Last Words
There are many other medications available to treat ADHD, but Adderall can be highly effective if used according to the guidelines mentioned above.
You just have to take the right dose at the right time and monitor for side effects.
If you’re not getting the benefit from Adderall you want, consult a doctor to explore better options and dosages for your needs.
