People with heart conditions should use Modvigil 200 with caution and only under a doctor’s supervision. Modvigil 200 can increase heart rate and blood pressure, which may pose risks for individuals with pre-existing heart issues such as hypertension, arrhythmias, or heart disease. Those with a history of chest pain, heart attacks, or cardiovascular conditions should consult their healthcare provider before taking Modvigil. In some cases, alternative treatments may be recommended to avoid potential complications. Regular monitoring of blood pressure and heart function is advised for those who require Modvigil for excessive sleepiness.
