The first and most important step in determining whether Sildigra is safe for you is to consult a doctor or a qualified healthcare provider. They will evaluate your cardiovascular health, as Sildenafil affects blood flow and can lower blood pressure, which can be risky for people with heart conditions, recent strokes, unstable angina, or low blood pressure. If you’re taking nitrate medications, you must not take Sildigra, as combining the two can cause a life-threatening drop in blood pressure. Similarly, if you’re using medications for pulmonary hypertension, such as riociguat, Sildigra is contraindicated.
