Sildenafil is an ingredient in Suhagra 100 MG Tablets. The blue pill is its more well-known name. It is a medication that works well for treating male erectile dysfunction (ED). A guy with erectile dysfunction is unable to get and/or keep an erection strong enough for sexual activity. As directed by your physician, Suhagra 100 MG Tablets may be taken with or without food. It is advised that you take the tablet 30 to 60 minutes prior to sexual activity. But you can also take it up to four hours prior to having sex. Only when you are sexually stimulated can this medication help you get and sustain an erection.
