How does Viagra Connect® work?
Viagra Connect® is a treatment for erectile dysfunction that helps you get and maintain an erection when you are sexually aroused.
Available without a prescription from regulated UK pharmacies since 2018, it contains sildenafil 50mg, a type of medicine known as a PDE5 inhibitor.
It works by improving blood flow to the penis during sexual stimulation, helping you achieve and maintain an erection suitable for sexual activity.
Viagra Connect® does not cause an erection without sexual arousal. You still need sexual arousal for it to work.
Once sexual activity is over, your erection will go down naturally, just as it normally would.

Viagra Connect® supports this process by:
- Relaxing blood vessels in the penis

It only works when you are sexually stimulated - it will not work on its own without arousal.
