Tadalafil (Generic Cialis)

Tadalafil is the active ingredient in Cialis, distinguished by its exceptionally long duration of action—up to 36 hours per dose. This extended window eliminates the need to plan around a pill, allowing for more spontaneous sexual activity. Tadalafil is available in two dosing approaches: on-demand (10-20mg before activity) or daily low-dose (5mg) for round-the-clock readiness.

Daily tadalafil is particularly popular among men who want to eliminate performance anxiety entirely, as they're always 'ready' without needing to think about timing. At hi-doctor.ai, our doctors help you choose between on-demand and daily dosing based on your lifestyle and needs.

Like sildenafil, tadalafil inhibits PDE5 to enhance blood flow. Its molecular structure allows it to remain active in the body much longer (half-life ~17.5 hours vs ~4 hours for sildenafil).

Common: headache, back pain, nasal congestion, muscle aches, indigestion. Generally milder than sildenafil. Contraindicated with nitrates.
