Silagra 100 is similar to other medications such as Viagra, as they both contain sildenafil citrate and function in a similar manner to treat ED. It is important to note that Silagra 100 should be taken as directed by a healthcare provider, usually about 30 minutes to an hour before sexual activity. The effects of sildenafil typically last for about four to six hours.
