ADHD Medication, Side Effects, Mechanism, and Effectiveness

In this article, we delve into ADHD medication, examining its effectiveness in alleviating symptoms and the potential side effects.


ADHD, a neurodevelopmental disorder, affects people of all ages, affecting their ability to concentrate, control impulses, and complete everyday chores. ADHD may be difficult to manage, but treatments can improve the quality of life. Medication is often prescribed.

What is ADHD Medication?

ADHD medication assists in alleviating symptoms such as hyperactivity, inattention, and impulsivity in individuals diagnosed with attention deficit hyperactivity disorder, previously referred to as ADD. Nonetheless, it’s crucial to note that these medications do not provide a cure for ADHD. Discontinuing the drug often leads to a return of symptoms. Furthermore, these medications carry potential side effects and risks, and they aren’t the sole treatment available for managing ADHD symptoms.

Whether you’re the caregiver or the individual affected, having a clear understanding of the realities surrounding ADHD medication is essential. This knowledge helps make informed decisions regarding the most suitable approach for yourself or the individual with ADHD.

What is The Role of ADHD Medication?

ADHD medications function diversely based on their type. However, all ADHD medications operate by augmenting the levels of crucial brain chemicals known as neurotransmitters. These neurotransmitters primarily include dopamine and norepinephrine. Elevating the quantities of these neurotransmitters assists in alleviating ADHD symptoms, such as:

  • Enhancing attention span.
  • Diminishing hyperactivity.
  • Regulating impulsive behavior.
  • Managing executive dysfunction.

The impact of ADHD medications varies from person to person. What may be effective for one individual might not yield the same results for you or your child. The initial ADHD medication administered may not be suitable—it could lack effectiveness or cause inconvenient side effects. Alternatively, you might be prescribed the proper medication but require an adjusted dosage.

It is essential to inform your healthcare provider about all medications—prescription or over-the-counter—you or your child are taking. Additionally, disclose any consumption of caffeinated beverages or supplements, along with their daily quantities. The combination of certain medications can lead to adverse effects on the body.

Your healthcare provider may need to experiment with different medications and dosages to determine what best suits your or your child’s needs. They will monitor your or your child’s response and adjust the medication dosage to balance benefits and side effects.

Once the appropriate medication and dosage are identified, most individuals discover that ADHD medication helps alleviate their symptoms. Improvement in symptoms related to hyperactivity, attention span, and impulsive behaviors is commonly observed.

ADHD Medication List


Stimulants stand as the most commonly prescribed medications for attention deficit disorder, boasting the lengthiest history in treating ADHD and extensive research supporting their efficacy. This class of medication encompasses widely recognized drugs such as:

  • Ritalin, Concerta (methylphenidate).
  • Adderall (dextroamphetamine and amphetamine).
  • Focalin (dexmethylphenidate).
  • Dexedrine, ProCentra, Zenzedi (dextroamphetamine).
  • Vyvanse (lisdexamfetamine).
  • Evekeo, Adzenys, Dyanavel (amphetamine).

The mechanism of action for stimulant medications is believed to involve the elevation of dopamine levels in the brain. Dopamine, a neurotransmitter associated with motivation, pleasure, attention, and movement, is thought to be boosted by stimulant medications, consequently enhancing concentration and focus while curbing hyperactive and impulsive behaviors in many individuals with ADHD.

Stimulants designed for ADHD treatment are available in both short-acting and long-acting formulations. Short-acting stimulants reach their peak effect after several hours and typically require administration 2-3 times daily. In contrast, long-acting or extended-release stimulants offer a duration of action lasting 8-12 hours, usually necessitating only once-a-day dosing.

The long-acting variants of ADHD medication are often favored, especially considering that individuals with ADHD may encounter difficulties in adhering to medication schedules. Opting for a single daily dose presents a more manageable and convenient regimen.

How Does Medicating ADHD Work?

Medicating ADHD is a common approach used to manage the symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Medication is typically prescribed as part of a comprehensive treatment plan, including therapy, education or behavior interventions, and lifestyle modifications.

The primary goal of medicating ADHD is to improve the individual’s ability to focus, control impulsive behaviors, and manage hyperactivity, allowing for better functioning in various settings, such as school, work, and personal relationships.

Medicating ADHD primarily involves the use of medications known as stimulants and non-stimulants. These medications work by affecting the levels of certain chemicals (neurotransmitters) in the brain that play a role in attention, impulse control, and hyperactivity.

  1. Stimulant ADHD Medications: Stimulant medications, such as methylphenidate (Ritalin) and amphetamine-based drugs (Adderall), are the most commonly prescribed medications for ADHD. They increase the availability of two key neurotransmitters: dopamine and norepinephrine. These neurotransmitters play a role in regulating attention, motivation, and executive functions.

By increasing the levels of dopamine and norepinephrine in the brain, stimulant medications help enhance the functioning of specific brain regions involved in attention and impulse control. This leads to improved attention span, focus, and the ability to regulate impulses and behavior.

  1. Non-Stimulant ADHD Medications: Non-stimulant medications, such as atomoxetine (Strattera), work differently from stimulants. They primarily target the neurotransmitter norepinephrine by blocking its reuptake, thereby increasing its availability in the brain. This helps regulate attention, hyperactivity, and impulsivity.

Non-stimulant medications are often considered an alternative for individuals who do not tolerate or respond well to stimulant medications. They may take longer to show their full effects compared to stimulants, but they can be effective in reducing ADHD symptoms and improving executive functions.

The choice of medication and dosage is typically determined based on an individual's specific symptoms, medical history, and treatment response. It is overseen by a healthcare professional experienced in ADHD management.

Side Effects of Medication For ADHD

Adverse effects frequently associated with stimulant medications encompass:

  1. Restlessness and jitteriness.
  2. Sleep disturbances.
  3. Reduced appetite.
  4. Headaches.
  5. Gastrointestinal discomfort.
  6. Irritability and mood fluctuations.
  7. Depressive symptoms.
  8. Dizziness.
  9. Accelerated heart rate.
  10. Tics.

Additionally, stimulant medications may induce alterations in personality. Some individuals may exhibit withdrawal tendencies, reduced spontaneity, rigidity, or diminished talkativeness. Others might develop symptoms indicative of obsessive-compulsive traits.

Due to their capacity to elevate blood pressure and heart rate, prolonged use of these ADHD medications raises concerns among experts regarding potential health risks. The prolonged administration of stimulant drugs for ADHD necessitates careful monitoring due to these physiological impacts on the cardiovascular system.

Coping with Side Effects of ADHD Medication

Most individuals, both children and adults, undergoing ADHD medication treatment will likely encounter a range of side effects. In certain cases, these side effects tend to diminish after the initial few weeks on the medication. Employing a few simple strategies might help alleviate or reduce these unpleasant effects.

  • Loss of appetite: To address decreased appetite, consider consuming healthy snacks throughout the day and delaying dinner until the medication’s effects have subsided.
  • Insomnia: If difficulty falling asleep persists, try taking the stimulant earlier in the day. For those using extended-release stimulants, switching to the short-acting variant could also be beneficial. It’s advisable to avoid caffeinated beverages, especially in the afternoon or evening.
  • Stomach discomfort or headaches: Avoid taking medication on an empty stomach, as this might cause nausea, stomach discomfort, or headaches. Consider shifting to a long-acting medication if headaches emerge as the drug wears off.
  • Dizziness: Check blood pressure levels initially. If they are regular, consider reducing the dose or transitioning to a long-acting stimulant. Adequate hydration is also crucial.
  • Mood fluctuations: If the medication leads to irritability, depression, or agitation, try decreasing the dosage. Emotional changes might also result from the rebound effect. In such cases, overlapping doses or switching to an extended-release drug could be beneficial.

If persistent side effects persist despite managing them actively, consult your doctor for potential dose adjustments or to explore alternative medications.

Many individuals respond more favorably to long-acting or extended-release formulations of ADHD medication. These versions gradually build up in the bloodstream and wear off gradually. This gradual process helps reduce fluctuations in medication levels, minimizing the likelihood of a rebound effect where symptoms resurface—often more intensely—upon the drug wearing off.

  1. What are the signs ADHD medication dose is too high?

    Signs that an ADHD medication dose may be too high can include physical symptoms such as restlessness, rapid heartbeat, elevated blood pressure, and headaches. Emotional and behavioral changes, such as increased irritability, excessive anxiety, mood swings, and impulsivity, can also indicate a high dose. Cognitive effects like racing thoughts, difficulty concentrating, and increased distractibility may also be present. If these symptoms persist or become severe, it is essential to consult with a healthcare professional to consider potential dosage adjustments or alternative treatment options.

  2. What are the signs ADHD medication dose is too low?

    Signs that an ADHD medication dose may be too low can vary from person to person. If the dose is insufficient, individuals may experience persistent ADHD symptoms that are not adequately managed. Some signs that the medication dose may be too low include ongoing difficulties with focus, attention, and impulse control. Other common signs include continued hyperactivity, impulsivity, and challenges in completing tasks or maintaining organization. If these symptoms persist despite medication use, it is essential to consult with a healthcare professional who can evaluate the situation and consider adjusting the medication dosage to address the individual’s needs better.

  3. What is ADHD medication?

    ADHD medicine treats ADHD. ADHD medications treat attention, hyperactivity, and impulsivity. ADHD medications include stimulants and non-stimulants. The most widely prescribed stimulants are methylphenidate (Ritalin) and amphetamine-based medicines (Adderall), which increase brain neurotransmitters. Non-stimulant drugs like atomoxetine (Strattera) and guanfacine (Intuniv) have distinct mechanisms of action and may be better for those who can’t handle stimulants. Symptoms, medical history, and treatment response dictate medicine and dose. An ADHD specialist oversees it.

  4. What does ADHD medication do?

    ADHD medication works by helping to regulate and balance certain neurotransmitters in the brain, specifically dopamine and norepinephrine. These neurotransmitters play a crucial role in attention, impulse control, and hyperactivity, which are the core symptoms of Attention Deficit Hyperactivity Disorder (ADHD). By increasing the availability of dopamine and norepinephrine or altering their reuptake, ADHD medication can improve the functioning of specific brain regions responsible for attention and executive functions. This leads to enhanced focus, reduced impulsivity, improved self-control, and better overall behavioral regulation.
