Sildenafil vs Tadalafil: Quick Comparison

The Drugs

Sildenafil (generic Viagra)

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

Tadalafil (generic Cialis)

  • Works for up to 36 hours
  • More spontaneous - no precise timing needed
  • Can also be taken daily at low dose
  • Slightly more expensive but very popular

Most men prefer tadalafil for the flexibility, but sildenafil works just as well for planned occasions.


Services That Offer Both

  • Hims - offers both, competitive pricing, good app experience
  • Roman (Ro) - offers both, strong medical support, discreet packaging
  • Keeps - offers both, straightforward pricing
  • GoodRx + local pharmacy - not a telehealth service, but you can get prescriptions filled at very low cost (sometimes $10-15/month for generic)

My Suggestion

Ask your provider about tadalafil daily (2.5-5mg) if you want the most convenience, or sildenafil 50mg on-demand if cost is the priority.

Roman or Hims are solid starting points for the telehealth consultation.
