Fildena 200 is a high-dose medication designed to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate (200 mg), a potent PDE-5 inhibitor that enhances blood flow to the penis, enabling a firm and lasting erection when sexually stimulated. This tablet is taken orally about 30-60 minutes before sexual activity, with effects lasting up to 4-5 hours. Common side effects include headache, flushing, dizziness, or indigestion. It is not an aphrodisiac and requires sexual arousal to work. Consult a doctor before use, especially if you have heart conditions, low blood pressure, or are taking nitrates. Avoid alcohol and grapefruit for optimal results.
