Safety Information

Both therapeutic and supratherapeutic doses of vardenafil can produce an increase in the QTc interval.

Record Status

Dronedarone is associated with a dose-related increase in the QTc interval. Coadministration of other drugs that also prolong the QT interval may result in additive QT prolongation. Therapeutic and supratherapeutic doses of vardenafil can produce an increase in QTc interval. Dronedarone is a moderate inhibitor buy cheapest levitra of CYP3A4, the primary isoenzyme responsible for the metabolism of vardenafil. Droperidol: (Major) Concomitant use of vardenafil and droperidol increases the risk of QT/QTc prolongation and torsade de pointes (TdP).

Drug interactions

Dutasteride; Tamsulosin: (Moderate) Due to the potential for symptomatic hypotension, patients should be stable on tamsulosin therapy before initiating therapy with the lowest dose of vardenafil. Conversely, patients already receiving an optimized dose of vardenafil should be started on the lowest dose of tamsulosin; increases in the alpha-blocker dose should be done in a stepwise fashion. Other variables, such as intravascular volume depletion, concurrent antihypertensive therapy, or evidence of hemodynamic instability with alpha-blocker monotherapy, may affect the safety of concomitant use of vardenafil and tamsulosin. Duvelisib: (Major) Do not use vardenafil orally disintegrating tablets with duvelisib due to increased vardenafil exposure; do not exceed a single dose of 5 mg per 24-hour period of vardenafil oral tablets. Vardenafil is primarily metabolized by CYP3A4/5; duvelisib is a moderate CYP3A4 inhibitor.
