Cialis® is a branded prescription treatment for erectile dysfunction containing tadalafil. It belongs to a group of medicines known as PDE-5 inhibitors and is designed to help men achieve and maintain an erection suitable for sexual activity.
Erectile dysfunction is common and can affect confidence and relationships. Cialis treats the physical symptoms by supporting blood flow but does not cure the underlying cause or increase sexual desire.
Cialis works by blocking the enzyme phosphodiesterase type-5 (PDE-5). This helps relax blood vessels and improve blood flow to the penis during sexual stimulation.
Sexual arousal is required for the medication to be effective.
One of the main differences between Cialis and sildenafil-based treatments is duration. Cialis can remain effective for up to 36 hours, providing a longer window of opportunity rather than a shorter timed effect.
Cialis tablets are available in:
-2.5mg
-5mg
-10mg
-20mg
Lower strengths (2.5mg or 5mg) may be prescribed for daily use. Higher strengths (10mg or 20mg) are typically taken as needed before sexual activity.
Your prescriber will determine the most appropriate dose based on your medical history and lifestyle.
Cialis may be suitable for adult men experiencing erectile dysfunction.
It may not be appropriate if you:
-Take nitrate medications
-Have certain heart or liver conditions
-Have recently had a stroke or heart attack

-Are advised to avoid sexual activity
Suitability is assessed during your confidential online consultation.
