Dexamfetamine, also known as dextroamphetamine, is the dextrorotatory enantiomer of amphetamine. It’s a central nervous system (CNS) stimulant primarily used in medicine for treating attention deficit hyperactivity disorder (ADHD) and narcolepsy. Here’s a breakdown of key facts:

Medical Uses

• ADHD: Improves focus, attention, and impulse control in children (typically 6+ years) and adults. Often prescribed as part of behavioral therapy.
• Narcolepsy: Helps reduce excessive daytime sleepiness.
• Common brand names: Dexedrine, Dexampex, or in combinations like Adderall (mixed amphetamine salts).

How It Works

• Mechanism: Increases levels of neurotransmitters like dopamine and norepinephrine in the brain by promoting their release and blocking reuptake. This enhances alertness and executive function.
• Forms: Immediate-release tablets, extended-release capsules, or oral solutions. Doses start low (e.g., 5-10 mg/day for ADHD) and are titrated based on response.

Dosage Guidelines (General, Consult a Doctor)

Always follow a healthcare provider’s prescription; do not self-medicate.

Side Effects

• Common: Insomnia, dry mouth, appetite loss, weight loss, increased heart rate/blood pressure, anxiety, headache.
• Serious: Potential for addiction, psychosis (high doses), cardiovascular issues (e.g., hypertension), growth suppression in children.
• Withdrawal: Fatigue, depression, irritability if stopped abruptly.

Risks and Warnings

• Controlled Substance: Schedule II in the US (high abuse potential). Misuse can lead to tolerance, dependence, or overdose (symptoms: agitation, hallucinations, seizures, hyperthermia).
• Contraindications: Avoid in glaucoma, severe hypertension, heart disease, hyperthyroidism, or with MAOIs (risk of hypertensive crisis).
• Interactions: Amplifies effects of caffeine, antidepressants, or alcohol; dangerous with cocaine or other stimulants.
• Evidence: FDA-approved based on clinical trials showing 70-80% efficacy in ADHD symptom reduction (e.g., MTA study, 1999). Long-term use requires monitoring for cardiovascular risks (AHA guidelines).

Legal Status

• Prescription-only worldwide. Illegal to possess without one due to abuse potential (e.g., as “speed” in recreational contexts).
