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.
