Understanding Cialis: The Weekend Pill Explained

Table of Contents

Cialis (tadalafil) has earned the nickname 'The Weekend Pill' due to its remarkably long duration of action. Unlike other ED medications that last 4-6 hours, Cialis can remain effective for up to 36 hours.

How It Works

Tadalafil works by inhibiting the PDE5 enzyme, which allows increased blood flow when sexually stimulated.

Daily vs As-Needed

Cialis is unique in offering both an as-needed dose (10-20mg) and a daily low-dose option (2.5-5mg), providing flexibility for different lifestyles.
