Can I take Dextroamphetamine and Intuniv together?

Why this happens

Dextroamphetamine increases the release of chemicals like norepinephrine which stimulate the heart and blood vessels. Intuniv works by stimulating specific receptors (alpha-2A) in the brain that tell the body to lower blood pressure and heart rate. When used together, they can cause unpredictable fluctuations in blood pressure or excessive slowing of the heart rate (bradycardia). Additionally, both can affect the central nervous system, potentially increasing drowsiness.

This combination is common in specialist ADHD treatment, but you must be monitored closely by your doctor. Have your blood pressure and heart rate checked regularly, especially when starting or changing doses. Seek medical advice if you feel very dizzy, faint, or notice a very slow or racing heartbeat. Do not stop taking Intuniv suddenly, as this can cause a dangerous spike in blood pressure.
