Sildenafil vs Tadalafil: Quick Comparison

The Drugs

Sildenafil (generic Viagra)

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

Tadalafil (generic Cialis)

  • Works for up to 36 hours ("the weekend pill")
  • More spontaneous since the window is longer
  • Can be taken daily at low dose
  • Slightly more expensive but very convenient

Most men prefer tadalafil for the flexibility, but sildenafil works well if you're more planned about timing.

Services Offering Both

  • Hims – offers both, easy online process, competitive pricing
  • Roman (Ro) – offers both, strong medical review process, good reputation
  • Keeps – offers both, straightforward and affordable
  • GoodRx + local telehealth – can get prescriptions filled very cheaply at pharmacies like Costco or Mark Cuban's Cost Plus Drugs

My Recommendation

Start with tadalafil daily (2.5-5mg) for ease of use, and use Roman or Hims for a smooth consultation process.

Always consult the prescribing doctor honestly about your health history.
