Sofia points the PDE5 milligram after the nitrate spray is gone. She runs an andrology clinic where the first question is not brand - it is whether a chest spray, a guanylate-cyclase drug, or a QT add-on is still in the drawer. Only then does she talk Cialis 5 mg as-needed, a 50 mg diamond, or Levitra 5 or 20 mg.
On this thread she writes the hold first: empty plate for sildenafil, QT line for vardenafil, a 5 mg PRN card versus a leftover daily almond. A headache after dose one is usually noise. A second tablet the same night is not a point.
She will not pick a favourite molecule for a reader she has not examined. Mail here is teaching. Bring the spray list to your own urologist.
