Combining Adderall, a stimulant prescribed for ADHD or narcolepsy, with caffeine can increase alertness and energy, but it also raises significant risks. Both substances stimulate the central nervous system, which can lead to heightened heart rate, elevated blood pressure, anxiety, jitteriness, and insomnia. In some cases, this combination may trigger more serious cardiovascular issues or exacerbate mental health symptoms like panic or irritability. While some people may feel a temporary energy boost, the potential for side effects and overstimulation makes this combination risky. It’s essential to consult a healthcare provider before using Adderall alongside caffeinated products to ensure safe use and avoid harmful interactions.
