Sildenafil, the active ingredient in Cenforce 200 mg, can also cause blood vessels to dilate throughout the body, not just in the penis. While this effect is beneficial for erectile function, it can also lead to a temporary decrease in blood pressure. For individuals with pre-existing cardiovascular conditions, such as coronary artery disease, heart failure, or uncontrolled hypertension, this drop in blood pressure can pose a risk, potentially causing symptoms such as dizziness, fainting, or even a heart attack or stroke in rare cases.
