Tadalafil is the active ingredient in Cialis, available here as a generic tablet. It belongs to a class of medications called PDE5 inhibitors, which work by relaxing blood vessels and improving blood flow where it matters — supporting the physical side of erectile function. Compared with other medications in its class, tadalafil stays active in the body longer, which is why many men prefer it for flexibility.
It's typically used by men who want reliable support for erectile function without planning their day around a pill. Some use it situationally; others are prescribed a routine that fits a more consistent pattern. Your provider determines the strength and schedule that make sense for you.
OpenDoseRx treatments are dispensed only after a licensed provider reviews your health intake and determines a prescription is appropriate for you.
