What it is
Sildenafil is a PDE5 inhibitor — the same active ingredient as the brand-name product it's generic for. It relaxes blood vessels so that, with arousal, blood flows more easily to the penis. It's taken on an as-needed basis before sex.
How to use it
Take one dose roughly 30–60 minutes before activity, as directed by your provider. A heavy or high-fat meal can slow it down. It requires sexual arousal to work.
