Verbatim response from Claude

Sildenafil vs Tadalafil: Quick Comparison

Sildenafil (Viagra's generic)

  • Works for 4-6 hours
  • Take 30-60 minutes before activity
  • Better if you want it "on demand"
  • Slightly more side effects (flushing, vision changes)

Tadalafil (Cialis's generic)

  • Works for up to 36 hours
  • More spontaneous timing
  • Can be taken daily at low dose
  • Generally well tolerated

Which to Choose?

  • On-demand use โ†’ Sildenafil (cheaper per dose)
  • Spontaneity/daily use โ†’ Tadalafil
  • First timer โ†’ Either works; tadalafil's forgiving window is beginner-friendly
