How should I take generic viagra for best results ?

Take this medication by mouth as directed by your doctor to treat erectile dysfunction-ED.

Take sildenafil at least 30 minutes before sexual activity, but not more than 4 hours (1 hour before is the most effective). Take no more than once a day.

One to four hours before sexual activity, take generic viagra. If you take it less than an hour before you have sex, your erection may not be as firm or as long-lasting as you’d like.

Before you start or change your dose, talk to your doctor about a safe starting dose.
