• Absorption is not significantly affected by food, unlike some other ED drugs.
• A high-fat meal may delay the time to reach maximum concentration.
• For predictable timing, take on an empty stomach or with a light meal.
• Maximum plasma concentration is reached approximately 2 hours after dosing.
• The medication is highly protein-bound in the bloodstream.
• It is not removed by dialysis, so dose adjustment is critical in renal failure.
• In mild to moderate renal impairment, a maximum dose of 10mg is often advised.
• In severe renal impairment, the maximum recommended dose is 5mg.
• For patients on dialysis, use is not recommended.
