Written By Patricia Allamon

What Are Psychostimulant Medications?

Psychostimulant medications are commonly used to treat:

  • Attention-deficit/hyperactivity disorder (ADHD)

  • Executive dysfunction

  • Inattention

  • Daytime fatigue or hypersomnia in select cases

These medications work by increasing certain neurotransmitters in the brain, primarily dopamine and norepinephrine, which can improve:

  • Focus

  • Attention

  • Motivation

  • Task completion

  • Mental clarity

  • Impulse control

Examples include:

  • Adderall

  • Vyvanse

  • Ritalin

  • Concerta

  • Dexedrine

What to Expect When Starting

Common Early Effects

Many patients notice:

  • Improved focus

  • Increased mental energy

  • Better motivation

  • Reduced distractibility

  • Improved productivity

Some people feel benefits immediately, while others require dose adjustments over time.

Common Side Effects

Possible side effects include:

  • Decreased appetite

  • Dry mouth

  • Difficulty sleeping

  • Increased heart rate

  • Mild anxiety or jitteriness

  • Headache

  • Irritability

  • Mild nausea

Many side effects improve after the first few weeks or with dose adjustments.

Important Tips for Success

Eat Enough Protein and Calories

Appetite suppression is very common.

Helpful strategies:

  • Eat breakfast before taking medication if possible

  • Prioritize protein intake

  • Do not intentionally skip meals

  • Stay hydrated throughout the day

Low calorie intake can worsen:

  • Fatigue

  • Anxiety

  • Mood changes

  • Headaches

  • Muscle loss

Sleep Is Critical

Psychostimulants can interfere with sleep if taken too late.

Recommendations:

  • Take medication early in the day unless otherwise instructed

  • Maintain a consistent sleep schedule

  • Avoid excess caffeine or other stimulants

Poor sleep can worsen ADHD symptoms and medication tolerance.

Hydration Matters

Stimulants may increase dehydration risk.

Aim for:

  • Adequate water intake

  • Electrolyte support if needed

  • Limiting excess caffeine

Signs of dehydration:

  • Headache

  • Dizziness

  • Constipation

  • Rapid heart rate

Avoid Misuse

Take medication exactly as prescribed.

Do NOT:

  • Increase doses on your own

  • Combine with recreational stimulants

  • Share medication

  • Use extra doses for energy, studying, or weight loss

These medications are controlled substances and may carry risks of dependence or misuse.

Important Monitoring

Your physician may monitor:

  • Blood pressure

  • Heart rate

  • Weight

  • Sleep

  • Mood

  • Anxiety symptoms

  • Appetite

Periodic follow-up visits are important for safe prescribing.

When to Contact Your Physician

Please contact your physician if you develop:

  • Chest pain

  • Shortness of breath

  • Fainting

  • Severe anxiety or panic

  • Significant mood changes

  • Severe insomnia

  • Persistent rapid heart rate

  • New tics or unusual movements

Seek emergency care for severe symptoms.

Medication Interactions

Tell your physician about all:

  • Prescription medications

  • Supplements

  • Caffeine or energy product use

  • Cannabis or alcohol use

  • Over-the-counter cold medications

Some combinations may increase side effects or cardiovascular risks.

Important Safety Information

Psychostimulants may not be appropriate for patients with:

  • Uncontrolled high blood pressure

  • Certain heart conditions

  • Active substance misuse

  • Severe uncontrolled anxiety

  • Certain psychiatric conditions

Always discuss your full medical history with your physician.
