PDE5 Inhibitor Therapy
Sildenafil & Tadalafil — Proven Performance Support in Sioux City
Sildenafil (the active ingredient in Viagra) and tadalafil (the active ingredient in Cialis) are FDA-approved phosphodiesterase type 5 (PDE5) inhibitors that enhance blood flow to penile tissue by blocking the enzyme that degrades cGMP — the molecule that mediates smooth muscle relaxation and engorgement. Sildenafil is typically taken on-demand one hour before sexual activity and lasts four to six hours. Tadalafil can be taken either as a daily low-dose (2.5–5mg) for spontaneous readiness or as a higher on-demand dose (10–20mg). Both medications are available at transparent direct-pay pricing at Prosper Health in Sioux City without requiring an insurance prior authorization or a specialist referral.
