Off-Prescription Adderall Linked to Measurable Cardiovascular Changes in Healthy Young Adults

A recent study from the Mayo Clinic, published in Mayo Clinic Proceedings, has revealed that a single 25 mg dose of amphetamine-dextroamphetamine salts, commonly known as Adderall, can induce measurable cardiovascular changes in healthy young adults who do not possess a medical prescription for the medication. Researchers observed significant increases in blood pressure, heart rate, and sympathetic nervous system activity, alongside a notable rise in heart rate upon standing.

Study Design and Methodology

The primary objective of the study was to investigate the acute effects of a single Adderall dose on cardiovascular hemodynamics, including blood pressure and heart rate, as well as sympathetic activity. The research specifically focused on young adults who were not medically indicated to use the medication. All participants in the study were individuals without prior exposure to Adderall.

Dr. Anna Svatikova, a Mayo Clinic cardiologist and senior author of the study, noted the growing trend of nonmedical Adderall use.

"While Adderall is considered safe and effective when prescribed and monitored for conditions like ADHD, the risks associated with its unsupervised use are often underestimated."

Key Cardiovascular Findings

The study reported several significant findings related to acute cardiovascular responses:

• A single 25 mg dose of Adderall resulted in notable increases in blood pressure and heart rate.
• The medication also led to an activation of the body's stress-response system.
• Researchers observed a substantial increase in heart rate upon standing.

Kiran Somers, D.O., who served as the lead author of the study, provided a specific detail:

"The average heart rate increase when transitioning to a standing position doubled from 19 beats per minute before taking Adderall to 38 beats per minute afterward."

These effects were observed even in participants who had no prior experience with the medication.

Important Context and Limitations

The researchers emphasized that the findings of this study specifically apply to the off-prescription use of Adderall. They cautioned against extrapolating these results to the long-term, supervised use of the medication for the treatment of ADHD or other medical conditions for which therapeutic benefits are well-established.
