How Tadalafil Works

Tadalafil enhances nitric oxide signaling by inhibiting the enzyme phosphodiesterase type 5 (PDE5).

This allows:

  • Improved arterial dilation
  • Increased blood flow to penile tissue
  • Stronger and more sustainable erections (when sexually stimulated)

Important: Tadalafil does not create automatic erections. Sexual stimulation is still required.


How Long Does Tadalafil Last?

One of tadalafilโ€™s distinguishing features is duration.

  • Effects may last up to 36 hours
  • Often called the โ€œweekend medicationโ€
  • Can provide a longer window of responsiveness compared to sildenafil

This longer duration reduces performance timing pressure for many men.


Dosing Options

Tadalafil is typically prescribed in two ways:

1๏ธโƒฃ As-Needed Dosing

  • Taken before sexual activity
  • Higher dose
  • Used when needed

2๏ธโƒฃ Daily Low-Dose Option

  • Lower dose taken once daily
  • Maintains steady blood levels
  • May reduce spontaneity pressure
  • Also used in certain prostate conditions

  • Mild to moderate vascular ED
  • Diabetes-related ED
