Atomoxetine is prescribed to treat:

• Attention deficit hyperactivity disorder (adhd) • Various related conditions in the mental health category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

Condition	Starting Dose	Maintenance Dose
ADHD (adults and children >= 70 kg)	40 mg once daily for 3 days	Increase to 80 mg/day; max 100 mg/day after 2–4 weeks if needed
ADHD (children and adolescents < 70 kg)	0.5 mg/kg/day for 3 days	Target 1.2 mg/kg/day; max 1.4 mg/kg/day or 100 mg/day, whichever is less
ADHD with concurrent strong CYP2D6 inhibitor or known poor metabolizer	40 mg once daily (adults)	Titrate slowly; consider not exceeding 80 mg/day
Hepatic impairment (Child-Pugh B)	Reduce starting and target dose by 50%	50% of usual maintenance dose

Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Atomoxetine is primarily metabolized by CYP2D6, and its norepinephrine activity creates several pharmacodynamic interactions. About 7% of Caucasians and 2% of African Americans are CYP2D6 poor metabolizers and experience higher exposure.

Strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine, bupropion, quinidine): Increase atomoxetine plasma levels several-fold. Initiate at the standard starting dose but do not titrate up for at least 4 weeks; cap maintenance dosing at lower levels.
MAO inhibitors (e.g., phenelzine, tranylcypromine, linezolid): Concurrent use can produce hypertensive crisis or serotonin-syndrome-like reactions. Do not use within 14 days of an MAO inhibitor.
Other sympathomimetics or pressor agents (e.g., pseudoephedrine, albuterol systemic, stimulant ADHD medications): Additive increases in heart rate and blood pressure. Monitor vital signs and avoid combinations when possible.
QT-prolonging drugs (e.g., methadone, ondansetron, certain antipsychotics): Atomoxetine can modestly prolong QT. Combine cautiously and review baseline ECG in patients with cardiac risk factors.
Antihypertensives: Atomoxetine can blunt the effect of some antihypertensives by raising sympathetic tone. Monitor blood pressure when starting therapy.

Frequently Asked Questions

Unlike stimulant ADHD medications, atomoxetine does not produce an immediate effect on the day it is taken. Most patients begin to notice symptom improvement after 2 to 4 weeks of consistent dosing, and full benefit is typically assessed at 6 to 12 weeks. Patience and steady daily use are essential.

Atomoxetine can be given as a single morning dose or split into morning and late afternoon. Twice-daily dosing may help patients who experience GI upset or sleep disturbance. Taking it with food can reduce nausea, especially when starting therapy.

No. Atomoxetine is not a controlled substance and is not classified as a stimulant. It does not produce euphoria and is not associated with abuse or dependence. This makes it a useful option for patients with a history of substance use disorder or those who prefer to avoid stimulants.

Atomoxetine can modestly raise heart rate (typically by 5–10 beats per minute) and blood pressure. Most patients tolerate these changes without difficulty, but baseline and periodic monitoring is recommended, particularly for patients with a history of hypertension, arrhythmia, or structural heart disease.

Rare but important risks include severe liver injury (report fatigue, dark urine, yellowing of skin), suicidal thoughts in children and adolescents (especially in the first months of treatment), and significant cardiovascular events in those with underlying heart disease. Report any new mood changes, jaundice, or chest symptoms promptly.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

✓How will we measure whether atomoxetine is helping my ADHD symptoms?
✓Should I have a baseline ECG or cardiology evaluation before starting?
✓How often should my blood pressure, heart rate, and weight be checked while on this medication?
✓What signs of liver problems or mood changes should prompt me to call you between visits?
✓Would a stimulant be a more effective option for my situation, and what are the trade-offs?
