Sildenafil 200 mg is a high-dose medication used to treat men suffering from erectile dysfunction (ED), especially in cases where lower doses have proven ineffective. It works by increasing blood flow to the penis, helping achieve and sustain a firm erection during sexual activity. As a potent PDE5 inhibitor, Sildenafil 200 mg should be taken 30 to 60 minutes before intercourse and only under medical supervision due to its strength. The effects can last up to 4–6 hours. This dosage is intended for men with severe ED and should not be taken without consulting a healthcare provider.
