Does Aspirin Lower Blood Pressure?

Low-dose aspirin is known to reduce the risk of heart attack in high-risk patients. It also seems to help lower high blood pressure, but studies looking at this effect yield confusing results. Now there may be an explanation: aspirin only lowers blood pressure when taken at bedtime.

Does aspirin lower blood pressure immediately?

When aspirin was taken in the morning, it did not lower the blood pressure of patients. However, when taken at night, subjects taking aspirin saw their systolic blood pressure reading drop by 5.4 points and their diastolic pressure drop by 3.4 points, while those taking aspirin in the morning did not report any drop.

Can I take aspirin for high blood pressure?

High blood pressure (hypertension) is a risk factor for heart disease—and for years, a low dose of daily aspirin has been considered a safe and healthy way to prevent heart disease. It's reasonable, therefore, to associate aspirin with lowering blood pressure, as a key way of preventing heart attacks and strokes.
