A single 25mg dose of Adderall, a prescription stimulant, measurably elevates blood pressure and heart rate even in healthy young adults with no prior medical need for the drug, according to research presented by the Mayo Clinic. The findings, released Monday, underscore growing concerns about the non-medical utilize of attention deficit hyperactivity disorder (ADHD) medications, particularly among students seeking a cognitive edge.
The study, led by cardiologist Anna Svatikova and resident physician Kiran Somers, found that even a first-time, low dose of Adderall caused a significant increase in both systolic and diastolic blood pressure, as well as heart rate. The average increase in heart rate upon standing rose from 19 beats per minute before taking the medication to 38 beats per minute afterward, according to Somers.
“We observed that even in individuals without prior exposure, a 25mg dose leads to increases in blood pressure, heart rate, and activation of the body’s stress-response system,” Svatikova stated. “Adderall is sometimes used without a prescription, outside of a medical context, and many users are unaware of the direct strain it places on the cardiovascular system.”
While Adderall and its counterpart, Ritalin, are considered safe and effective when prescribed for ADHD, the Mayo Clinic research highlights the risks associated with off-label use. Ritalin, more commonly prescribed in the Netherlands, contains methylphenidate, another stimulant that primarily inhibits dopamine reuptake. Both medications aim to improve concentration and impulse control by increasing levels of norepinephrine and dopamine in the brain, but Adderall is generally considered more potent and longer-lasting.
The non-medical use of stimulants is particularly prevalent among students in the United States, with estimates suggesting that 5 to 15 percent have experimented with Adderall to enhance study performance, according to research cited by Additude Magazine. The trend mirrors a broader increase in ADHD medication prescriptions globally, though the reasons behind this rise are complex and multifaceted.
Researchers emphasize that their findings pertain specifically to non-prescribed use and do not necessarily reflect the effects of long-term, medically supervised treatment for ADHD. “The therapeutic benefits are well-established and significant for the treatment of ADHD or other specific medical conditions,” Svatikova clarified.
The study’s findings come as concerns grow about the potential long-term health consequences of widespread stimulant use, even among those with legitimate prescriptions. Recent reports have indicated a possible link between ADHD medication and a reduced lifespan in adults with the condition, though further research is needed to confirm this association.
