What could happen if a person with a heart murmur took 40 mg vyvanse?

If a person with a heart murmur took 40 mg of Vyvanse (lisdexamfetamine), they could potentially experience increased heart rate and blood pressure, which may exacerbate underlying cardiovascular issues. While many individuals with heart murmurs do not face significant risks, the stimulant effects of Vyvanse may lead to complications such as palpitations or, in rare cases, more severe cardiovascular events. It is crucial for individuals with pre-existing heart conditions to consult a healthcare professional before taking stimulant medications.
