How long does Cialis last?

Cialis lasts up to 36 hours for treating erectile dysfunction when taken as needed before sexual activity. It typically starts working within 30 minutes to 2 hours, reaching peak effect around 2 hours after taking it. You need sexual stimulation for it to help with erections during this window, and it does not cause continuous erections.

Key points:

  • Cialis provides effects for up to 36 hours.
  • Onset of action occurs within 30 minutes to 2 hours.
  • Peak blood levels happen around 2 hours post-dose.
  • Daily dosing keeps steady levels for ongoing erectile dysfunction support.
