Sildenafil vs Tadalafil: Quick Comparison

The Drugs

Sildenafil (generic Viagra)

  • Works for 4-6 hours
  • Take 30-60 min before activity
  • Better if you want it "on demand"

Tadalafil (generic Cialis)

  • Works for up to 36 hours
  • More spontaneous/flexible
  • Also available as a daily low-dose option

Which to Choose?

  • Sildenafil → planned encounters, occasional use, often cheaper per pill
  • Tadalafil → more spontaneous lifestyle, or daily dosing preference

Services Offering Both

Hims - offers both, easy online consultation, competitive pricing

Roman (Ro) - offers both, well-regarded medical review process

Keeps - offers both, straightforward pricing

eDrugstore - offers both, longer established

Wisp - offers both, also good for broader sexual health needs


My Suggestion

Roman or Hims are the most streamlined experiences. Many men start with tadalafil daily for convenience, then adjust based on results.

⚕️ A licensed provider through any of these services will make the final call based on your health history — be honest in your consultation.
