Suhagra 25 mg contains sildenafil citrate, which primarily works by relaxing blood vessels to increase blood flow. This action can lower blood pressure slightly. For most healthy individuals, this effect is mild and usually well-tolerated. However, because Suhagra affects blood vessels and blood pressure, it can have important effects on the heart, especially in people with existing heart conditions. Here’s what to consider: People with heart disease, angina (chest pain), or heart rhythm problems should consult a doctor before using Suhagra 25 mg . The drug can interact dangerously with nitrate medications (used for chest pain), causing a severe drop in blood pressure, which can be life-threatening. Those with uncontrolled high or low blood pressure, recent heart attack or stroke, or severe heart failure need medical advice before taking sildenafil. Mild side effects related to the heart can include flushing, dizziness, or palpitations. If you have any history of heart problems, a full medical evaluation by a healthcare professional is essential before using Suhagra 25 mg to ensure it’s safe for you.
