Sildenafil vs Tadalafil: Which PDE5 Inhibitor for ED?
Sildenafil and tadalafil are the two most-used ED medications in the world. The difference is timing, half-life, and how you want to live your life.
How they're different
Sildenafil: onset 30–60 minutes, duration 4–6 hours. On-demand only. The original Viagra.
Tadalafil: onset 60–120 minutes, duration 24–36 hours on-demand, or take a low dose (5 mg) daily for chronic readiness. The original Cialis.
Why daily tadalafil wins for most men
Once you remove the timing problem, intimacy becomes spontaneous again. The clinical literature backs this up: daily tadalafil consistently outperforms on-demand dosing in patient satisfaction. It also improves lower urinary tract symptoms, a bonus that compounds with age.
When sildenafil still wins
Cost-sensitive on-demand use. Some men feel cleaner on sildenafil. Fewer reported headaches, no facial flushing, less back pain. It's a worthwhile trial.
