Medical Information Notice: This page provides general information about tadalafil (Cialis) for educational purposes only. It is not a substitute for professional medical advice. A GP consultation is required before this medication can be prescribed. Tadalafil is a prescription-only medicine in Ireland.
Cialis is the brand name for tadalafil, a prescription medication used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called PDE5 inhibitors, which work by increasing blood flow to the penis during sexual arousal.
What makes tadalafil unique is its long duration of action. While sildenafil (Viagra) typically works for 4-6 hours, tadalafil can remain effective for up to 36 hours. This longer window allows for more spontaneous intimacy without needing to plan around taking medication.
Tadalafil is also available as a daily low-dose option (5mg), which maintains a constant level in your system. This allows for sexual activity at any time without needing to take a pill beforehand.
Tadalafil is a PDE5 inhibitor. During sexual arousal, the body releases nitric oxide, which triggers the production of cGMP - a chemical that relaxes smooth muscle in the penis and allows blood to flow in.
PDE5 is an enzyme that breaks down cGMP. By blocking PDE5, tadalafil allows cGMP levels to remain elevated, making it easier to achieve and maintain an erection when sexually aroused.
Important: Tadalafil does not cause automatic erections. Sexual stimulation is still required for it to work.
Up to 36 Hours
Tadalafil remains in your system longer than other ED medications, providing a wider window for spontaneous activity.
Your GP will recommend the most suitable dosage based on your health profile and preferences.
