Tadalafil

What is tadalafil?

Medication that chemically assists erections of the penis, with a longer lasting effect.

It's also known as Cialis.

What does tadalafil do?

Who can have tadalafil?

  • You usually need to be at least 18

How long does tadalafil last?

Tadalafil takes around half an hour to take effect, and the effects may last for over a day.

Are there other options?

Alternatives to tadalafil include vardenafil and sildenafil.

While tadalafil does have a longer lasting action than sildenafil and vardenfil, there is no evidence that any of the treatments is more effective than the others 1.

There is good medical evidence that all three treatments are safe 2, with the vast majority of side effects being minor (flushing, headaches, temporary back pain) and subsiding within a few weeks of treatment 3.

Where can I learn more?

You can read more about erectile dysfunction treatments on the NHS website.
