      "short_answer": "Tadalafil 20 mg should be interpreted within the regimen being used. Tadalafil can appear in erectile-dysfunction treatment with different timing patterns, so the same drug name does not automatically mean the same practical decision. Tadalafil is often chosen partly because its duration profile differs from shorter-acting PDE5 options.",

      "short_answer": "A lower tadalafil strength used regularly answers a different treatment question from a higher as-needed strength. Comparing the milligrams without considering the regimen can therefore be misleading. The page should stay focused on how 20 mg is actually being used.",
