Sildenafil (Viagra) is a proven treatment for erectile dysfunction (ED), but myths often lead to misuse and confusion. Contrary to popular belief, it doesn't work instantly—it takes 30–60 minutes and requires sexual stimulation. Higher doses won’t boost performance and can cause harmful side effects. Also, Sildenafil isn’t effective for all ED cases, especially those caused by psychological or medical conditions. Importantly, it doesn’t cause physical addiction, and younger men may also benefit under medical guidance. Always use it as prescribed and consult a doctor for personalized treatment.
