Clinical rationale

Sildenafil is a PDE5 inhibitor that augments the nitric oxide-cGMP pathway responsible for smooth-muscle relaxation in the corpus cavernosum. Large RCTs show response rates of 70-80% for organic erectile dysfunction at 50-100 mg. Provider review screens for cardiovascular safety, nitrate use, and drug interactions before dispensing.

Questions

• Sildenafil or tadalafil?+

  Sildenafil is short-window and on-demand; tadalafil is longer (24-36 hours) and often taken daily. See the compare guide - the right pick depends on frequency of need, side-effect profile, and whether daily dosing is easier to remember.
• Does it work the first time?+

  For most organic ED, yes - response rates sit at 70-80% across trials. Performance-anxiety cases can take a few tries to desensitize, and coaching helps there more than a higher dose.
• Can I drink on it?+

  One drink is usually fine. More than that blunts the response and raises the headache risk. Skip nitrate-containing recreational substances entirely - the interaction is dangerous.
• Is ED always vascular?+

  No, but new ED is often the earliest vascular warning before anything shows up on a cardiac workup. A basic lipid panel, fasting glucose, and testosterone are table stakes before blaming stress.
