Viagra vs Cialis: What’s the Difference?

Viagra vs Cialis: What’s the Difference?

Meta Description: Learn the key differences between Sildenafil and Tadalafil, Ireland’s most widely used erectile dysfunction tablets. 

When it comes to erectile dysfunction treatment, (Viagra) Sildenafil and (Cialis) Tadalafil are two of the most recognised names in Ireland. But what sets them apart? At McCabes Pharmacy, we’re here to help you understand the differences.

What is Sildenafil?
Sildenafil is a PDE5 inhibitor that helps increase blood flow to the penis. It’s typically taken 30–60 minutes before sexual activity, and its effects last for around 4–6 hours.

What is Tadalafil?
Tadalafil works in a similar way to Sildenafil but lasts much longer — up to 36 hours. Some men prefer Tadalafil for its flexibility and longer window of opportunity.

Key differences between Viagra and Cialis:

• Onset of action:
  Sildenafil: 30–60 minutes
  Tadalafil: 30–45 minutes

• Duration:
  Sildenafil: 4–6 hours
  Tadalafil: up to 36 hours

• Food interactions:
  Sildenafil may be less effective after a heavy or fatty meal.
  Tadalafil is less affected by food.

• Daily use option:
  Tadalafil comes in a low-dose daily version, ideal for men who prefer more spontaneity.
