About Sildenafil
Sildenafil (generic Viagra) — PDE5 inhibitor
The most widely prescribed ED medication in the UK. Available over the counter at 50mg as Viagra Connect, or on prescription at 25mg, 50mg, and 100mg. Lasts 4–6 hours.
Administration
Oral tablet, taken on-demand 30–60 minutes before sexual activity
How it works
Sildenafil blocks the PDE5 enzyme, allowing blood vessels in the penis to relax and widen when sexually aroused. This improves blood flow and helps achieve and maintain an erection. It typically takes 30–60 minutes to work.
