When too much blood is pumped into the arteries, blood pressure gets increased. Modafinil can increase blood pressure and therefore it can cause severe health issues. Modafinil medication for high blood pressure patients is not safe as it may lead to health risks such as stroke, inability to move the body, and speech. 

Modafinil blood pressure can also cause people with a history of heart disorder and taking blood thinners. If it is taken under such conditions, the heart rate can be increased causing severe heart problems.
