Product / population
VIAGRA for adult erectile dysfunction; not pulmonary-arterial-hypertension dosing.
Renal measure
Creatinine clearance in mL/min.

RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.

Renal dosing, restrictions and evidence limits

No renal adjustment is required at CrCl 50-80 or 30-49. With severe impairment below 30, consider a 25 mg starting dose because sildenafil exposure is increased. This is an erectile-dysfunction starting-dose recommendation, not a pulmonary-hypertension schedule or a statement that interacting drugs and cardiovascular contraindications can be disregarded.

Important source distinctions

Erectile-dysfunction source, not pulmonary-arterial-hypertension dosing. The original enzyme-name typo is retained as a source issue, not an accepted enzyme identifier.

Import versus clinical validation
Source-section locators identify where retained content came from. A source-section identifier does not assert that every numeric statement has been independently corroborated. The local text hash is not a hash of original HTML, an FDA PDF or SPL XML.

The original individual GlobalRPh pages commonly cite NIH/NLM DailyMed and instruct readers to review the applicable package insert for updates. That historical reference is preserved as context; it is not counted as an independently retrieved current label.
