Sildenafil

Sildenafil is the active ingredient in Viagra, offered here as a generic tablet. Like tadalafil, it's a PDE5 inhibitor: it works by relaxing blood vessels and increasing blood flow to support erectile function. Sildenafil has a shorter active window than tadalafil, which some men prefer for predictable, on-demand use.

It's one of the most widely prescribed medications for erectile difficulties, typically used by men who want a straightforward, as-needed option. Your provider selects a strength based on your health profile and can adjust it as needed.

OpenDoseRx treatments are dispensed only after a licensed provider reviews your health intake and determines a prescription is appropriate for you.
