Indications 

Minipress is prescribed to manage hypertension either alone or in combination with other drugs.  

This medication lowers blood pressure, which minimizes fatal and nonfatal cardiovascular events, particularly myocardial infarctions and strokes. 

Minipress belongs to the class of drugs known as alpha-blockers, which relax and widen blood vessels, allowing for improved blood flow throughout the body.

This medication may induce sudden fainting after the first dose or when the dosage is raised. To minimize the risk of fainting, physicians prescribe the lowest possible initial dose, which should be taken before bedtime. 

Subsequent doses may be gradually increased, with the first increased dose also taken at bedtime unless otherwise directed by a physician.
