Show Notes
A listener noticed his ADHD medication relieves his asthma symptoms, sparking a deep dive into pharmacology. We explore how stimulants like Vyvanse trigger the sympathetic nervous system, acting as a systemic bronchodilator by relaxing airway muscles. The conversation covers the historical roots of amphetamines as asthma treatments, the dangerous overlap with rescue inhalers, and why this "side effect" can mask serious inflammation. We also examine the fine line between therapeutic relief and stimulant-induced breathing anxiety.
