Will Strattera (atomoxetine) increase blood pressure to the same extent as Adderall (amphetamine and dextroamphetamine) in a patient with attention deficit hyperactivity disorder (ADHD) and pre-existing hypertension?

Will Strattera Raise Blood Pressure as Much as Adderall?

No, Strattera (atomoxetine) causes significantly less blood pressure elevation than Adderall (amphetamine) and is specifically recommended as the preferred first-line option for ADHD patients with hypertension. 1

Comparative Blood Pressure Effects

Adderall (Amphetamine)

• Amphetamines are explicitly listed by the American College of Cardiology and American Heart Association as medications that cause elevated blood pressure, with recommendations to discontinue or decrease the dose when blood pressure becomes elevated 1, 2
• Stimulants including amphetamines cause average increases of 1-4 mm Hg for both systolic and diastolic blood pressure and 1-2 beats per minute for heart rate 3, 1
• In adult studies, amphetamine treatment was associated with statistically significant increases of +5.4 mm Hg in systolic blood pressure and +7.3 mm Hg in heart rate 4
• 5-15% of patients may experience substantially larger increases in blood pressure and heart rate beyond these averages 1, 5

Strattera (Atomoxetine)

• Atomoxetine causes only small, statistically but not clinically significant increases in blood pressure and heart rate 6, 7
• In pediatric patients, atomoxetine showed small increases in diastolic blood pressure, while in adults there were small increases in mean systolic blood pressure 7
• These cardiovascular effects are minimal and of little clinical significance compared to stimulants 7
• The American Heart Association specifically recommends atomoxetine as a first-choice non-stimulant option for patients with controlled hypertension due to its minimal impact on blood pressure compared to stimulants 1

Clinical Recommendations for Hypertensive Patients

First-Line Treatment

• Start with atomoxetine rather than Adderall if the patient has pre-existing hypertension 1
• Atomoxetine provides 24-hour symptom control as a selective norepinephrine reuptake inhibitor without the pronounced cardiovascular effects of stimulants 1, 8
• Alternative non-stimulant options include alpha-2 adrenergic agonists (guanfacine-XR or clonidine-XR), which may actually lower blood pressure rather than raise it 1

If Stimulants Must Be Used

• Confirm blood pressure is well-controlled (target <130/80 mmHg) before initiating any stimulant, including Adderall 1
• Establish baseline cardiovascular parameters including blood pressure and heart rate 1
• Implement more frequent blood pressure monitoring (quarterly in adults) when using stimulants in hypertensive patients 1
• Consider long-acting stimulant formulations for smoother cardiovascular effects 1

Monitoring Algorithm

• Measure blood pressure and pulse at baseline before starting any ADHD medication 1, 8
• Recheck blood pressure at each dose adjustment 1
• If blood pressure rises above target (<130/80 mmHg) on Adderall: reduce the dose, switch to atomoxetine or other non-stimulant, or intensify antihypertensive therapy 1

Important Safety Considerations

Contraindications and Precautions

• Stimulants should be used with caution in patients with pre-existing hypertension as they may worsen blood pressure control 3, 5
• Pre-existing cardiovascular conditions reduce the likelihood that clinicians will prescribe stimulants (by 29% in one study), but do not affect atomoxetine prescribing rates 9
• Atomoxetine has no abuse potential and is not a controlled substance, making it particularly useful for patients at risk of substance abuse 6

Cardiovascular Risk Profile

• Both medications are associated with extremely low risk of serious cardiovascular events including sudden cardiac death at therapeutic doses 5
• The benefits of treating ADHD outweigh cardiovascular risks after adequate assessment, but great caution is advised with any known cardiovascular risk factors 5

Common Pitfalls to Avoid

• Do not assume all ADHD medications have equivalent cardiovascular effects—atomoxetine is distinctly safer for hypertensive patients 1, 7
• Do not start Adderall without first confirming adequate blood pressure control on current antihypertensive therapy 1
• Do not abruptly discontinue alpha-2 agonists (if used) as this can cause rebound hypertension 1
