Silagra 50 mg is a medication commonly used to treat Erectile Dysfunction (ED). It contains Sildenafil Citrate, which works by relaxing blood vessels in the penis and increasing blood flow during sexual stimulation. This helps men achieve and maintain a firm erection. The onset of Silagra 50 mg typically occurs within 30–60 minutes after oral administration. However, this can vary depending on individual factors such as metabolism, age, diet, and overall health. Sexual stimulation is required for the medication to work; it does not cause automatic erections.
