Four medicines,
read line by line
Prednisone at 2.5 mg, tadalafil as 5 mg daily or 10 mg when needed, sildenafil across 25, 50 and 100 mg, vardenafil from 2.5 up to 20 mg. Each one gets a full profile, briefings that go further, and a reader thread answered by a named clinician. Nothing here is for sale.
The clinician
One physician answers every thread
Dr. Marc Vidal reviews each page before it is published and writes the reader answers himself.
How a page gets written
Label, strength, review, publish
The same four steps for every medicine, and different sentences each time.
Label
Each page starts with the current US prescribing information and the warning that comes before any dose: tapering for prednisone, nitrates for tadalafil, the meal for sildenafil, cardiac rhythm for vardenafil.
Strength
One labelled strength anchors the page so the title, the summary and the text cannot drift apart - 2.5 mg prednisone, 5 mg daily or 10 mg as needed, 25 to 100 mg sildenafil, 2.5 to 20 mg vardenafil.
Review
Marc Vidal reads the draft before it goes live and his name stays on the page. What he writes is general teaching, not a plan for the person reading it.
Publish
Reader questions are answered at the foot of the page. Price tables name licensed US pharmacies and link only to that chain, with discount-card services left in the captions.
