Daily versus as-needed
Tadalafil can be prescribed on a daily schedule or taken as needed. The price comparison changes completely depending on schedule, strength, and tablet count.

Tadalafil may support response during a longer window, but sexual stimulation is still required. A clinician should select the dose and schedule.
