Focalin for ADHD: Uses, Dosage & Side Effects

What is Focalin?

Attention-deficit/hyperactivity disorder (ADHD) is a condition that causes focus and attention difficulties in adults and children. If you'd like to learn more about ADHD and its symptoms, please check with the NIMH ADHD treatment overview to find out more.

Thankfully, some medications can treat symptoms of ADHD and allow people to live a more functional life. One of these is the stimulant drug Focalin. Focalin ADHD medication is a stimulant medication, and it's the brand name for dexmethylphenidate. 

Focalin is available in two formulations: an immediate-release and an extended-release. Focalin is a central nervous system (CNS) stimulant that is FDA-approved to treat ADHD in children ages 6 and up, adolescents, and adults.

According to the DEA controlled substance schedules, Focalin is a Schedule II controlled substance. It is considered a controlled substance because it has the potential for abuse, misuse, and addiction.

ADHD Advisor services adults aged 18 and older with ADHD online via telehealth services. Let's take a closer look at how Focalin works for ADHD and compare it with other ADHD medications so you can learn more about this treatment option.

How Focalin Works

Focalin is the brand name for dexmethylphenidate, which is a CNS stimulant medication used in the treatment of ADHD. Dexmethylphenidate is the active d-isomer of methylphenidate, the only active isomer that is considered more potent than its racemic counterpart.

Single isomer stimulants are thought to have fewer side effects than the other mixed isomer preparations. As such, dexmethylphenidate offers symptom relief at a smaller dose than methylphenidate.

Dexmethylphenidate works to manage ADHD symptoms because it blocks the reabsorption or reuptake of two neurotransmitters in the brain associated with functions such as attention, focus, and impulsivity, known as dopamine and norepinephrine. By providing the brain, particularly the prefrontal cortex, with increased access to these neurotransmitters, attention and focus can be enhanced while impulsivity is reduced.

Who Can Take Focalin

Focalin, both the extended-release and the immediate-release formulations, are FDA-approved to treat ADHD in children, adolescents, and adults. Focalin XR, the extended-release form, is taken once a day, while the immediate-release form is often taken two to three times a day for symptom relief. Focalin is used off-label for people with narcolepsy.

Contraindications

Focalin is not a good treatment option for everyone, and there are some individuals who shouldn't take it. If you are allergic to dexmethylphenidate or any of the other listed ingredients in Focalin, you shouldn't take it, as you could have a serious allergic reaction.

Focalin can interact with many different medications, so you must let your doctor know about any medications that you take, including herbal products, supplements, vitamins, or over-the-counter medications.  Some other individuals who shouldn't take Focalin, the ADHD medication, include those who have:

• Bipolar disorder
  
• Psychotic disorders, including paranoia
  
• Motor tics
  
• Tourette syndrome
  
• Substance use disorder
  
• Glaucoma
  
• Severe anxiety
  
• Hypersensitivity
  
• History of stroke

People who have taken MAOIs in the last 14 days should not start Focalin due to a risk of severe drug interactions.

Cardiovascular Risks

As Focalin is a CNS stimulant, there are some cardiovascular risks to be aware of, especially with people who already have cardiac issues. Some cardiovascular risks include:

• Increasing blood pressure and heart rate
  
• Developing arrhythmias
  
• Worsening of existing heart-related conditions
  
• Serious cardiac events, including heart attack, stroke, or sudden death, especially in patients with heart abnormalities
  
• Chest pain

Dosages and Administration 

Let's take a look at the average dexmethylphenidate ADHD dosage. It's important to remember that only a licensed clinician can determine safe dosing, and these are only average doses.

Focalin IR

The typical starting dosage of Focalin IR is 2.5-5 mg, administered twice daily, with at least 4– 5 hours between doses. Depending on your response to the medication, the dose may be increased by 2.5 mg, up to a maximum of 20 mg per day.

Focalin IR is recommended to be taken in the morning, followed by the next dose during daytime hours, as an evening dose can cause sleep disruptions. Individuals switching from a methylphenidate dosage will require different dosage starting points until the proper dosage is determined.

Focalin XR

Focalin XR is the extended-release form of dexmethylphenidate. The starting Focalin XR dosage is 10 mg, taken once daily, as per the FDA's Focalin prescribing information. Your provider may increase the dosage by 5 mg if needed, up to a maximum dosage of 40 mg per day. 

Suppose you are currently taking methylphenidate or another stimulant medication and are switching over to Focalin XR. In that case, your provider may start you on a different starting dose until your proper dosage is determined.

Dosing adjustments are made on an individual basis and depend on your response to the medication. Focalin dosing can be individualized, depending on various factors, which is why you must only take the prescribed dosage that your healthcare provider recommends.

Side Effects and Risks

As with any medication, there are some potential side effects to be aware of. To learn more about possible side effects, you can check with DailyMed: Focalin XR.

Common Side Effects

Let's take a look at some of the common Focalin side effects. Some common side effects that can occur when taking this medication include the following: (MedlinePlus: dexmethylphenidate)

• Insomnia
  
• Dry mouth
  
• Appetite loss
  
• Headache
  
• Anxiety
  
• Stomach upset and nausea
  
• Nervousness
  
• Heart racing
  
• Sore throat
  
• Dizziness
  
• Increased blood pressure
  

Serious Side Effects

Some serious Focalin side effects may include:

• Hallucinations and delusions
  
• High blood pressure
  
• Rapid heart rate
  
• Mood changes
  
• New or worsening tics
  
• Slowed growth in young children
  
• Heart attack
  
• Stroke
  
• Sudden death
  
• Abuse, misuse, and addiction

FDA Boxed Warning

The FDA stimulant boxed warning is included with Focalin. This boxed warning states that Focalin, which is a controlled substance stimulant drug, has the potential for abuse, misuse, and addiction, especially if this medication is abused. The boxed warning also states that stroke, heart attack, and sudden death are possible, especially in individuals with heart conditions.

The FDA released an updated boxed warning in July 2025 for all extended-release stimulant drugs, stating that children under six are at a greater risk of adverse side effects, especially growth suppression and weight loss. The "Limitation of Use" section discusses how young children in this age group were found to have higher concentrations of the drug in the body, which led to more unwanted side effects, including weight loss.

It's important to mention here at ADHD Advisor that we do not treat anyone who is not an adult aged 18 and older.

If you experience any serious side effects, please notify your healthcare provider immediately. You can also report any adverse effects to the FDA's MedWatch program.

Focalin vs. Other ADHD Medications

You can access CHADD on stimulant medications to find out more about different ADHD medications. Now, let's take a look at how Focalin compares with other ADHD medications.

Focalin vs Ritalin/Concerta

Focalin, Ritalin, and Concerta are part of the same stimulant drug family. When comparing Focalin vs Ritalin, Focalin contains only the d-methylphenidate isomer, making it more potent than the racemic formulation of Ritalin, which contains a mix of both d- and l-methylphenidate. 

By using a more potent isomer, Focalin may potentially cause fewer side effects than Concerta and Ritalin. All three stimulants help manage symptoms of ADHD, including impulsivity, inattention, and focus issues.

Focalin vs Amphetamines (Adderall, Vyvanse)

Focalin and amphetamines like Adderall and Vyvanse are all stimulant medications used to manage ADHD symptoms, but they are different classes of drugs. Focalin is dexmethylphenidate, and Adderall and Vyvanse are amphetamines. 

They also have a different mechanism of action. Focalin blocks the reabsorption of dopamine and norepinephrine, and amphetamines also do this. However, amphetamines also stimulate the nerve terminals, causing the release of new neurotransmitters. 

Both types of stimulants help to increase focus and attention, and both are available in extended-release and immediate-release formulations. Tolerability varies between these two types of stimulants, and some people may tolerate Focalin better than amphetamines or vice versa.

Focalin vs Non-stimulants

Focalin and non-stimulants vary in their mechanism of action, efficacy, and onset. Focalin affects both norepinephrine and dopamine levels, while non-stimulants typically only affect norepinephrine. 

Stimulants typically provide faster relief for ADHD symptoms, and Focalin may begin to work more quickly than non-stimulant medications. In contrast, non-stimulants typically take longer to take effect in the body. Focalin may cause insomnia or rapid heart rate, while non-stimulants may cause drowsiness or fatigue.

But Focalin has a greater potential for abuse, and most non-stimulants do not have this risk, making them a better choice for people with substance use disorder or who do not tolerate stimulants well.
