Aspirin is often recommended for individuals with high blood pressure, according to WebMD. Aspirin can be quite effective at preventing heart attack at even low doses when taken daily.
Taking aspirin at night rather than in the morning has been shown in preliminary studies to be more effective on lowering blood pressure, reports WebMD.
Do not take daily aspirin in order to lower blood pressure unless recommended by a doctor, as people with certain conditions should not take aspirin. Those who are already on blood-thinners should especially be sure to consult with a doctor before starting an aspirin regimen. Additionally, individuals should not abruptly stop their daily aspirin dose as this can result in a drastic rebound effect on blood pressure, according to the Mayo Clinic.
