Gettting started with Vardenafil (Levitra™️)
Use reduced doses of no more than 2.5 mg every 72 hours of vardenafil oral tablets with increased monitoring for adverse reactions.
Assessment of study quality
May increase dose up to 20 mg PO as needed approximately 60 minutes before anticipated sexual activity. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions. Patients with mild hepatic impairment (Child-Pugh class A): No dose adjustment is required. Patients with moderate hepatic impairment (Child-Pugh class B): Decrease starting dose to 5 mg/day PO using the regular tablets; the maximum dose should not exceed 10 mg/day PO. Do not use vardenafil orally disintegrating tablets in patients with moderate hepatic impairment.Patients with severe hepatic impairment (Child-Pugh class C): Do not use.

CrCl 30 mL/minute or more: No dosage adjustments are needed. HemodialysisDo not use vardenafil in patients requiring dialysis; vardenafil has not been studied in these patients. Abarelix: (Major) Avoid use of vardenafil in patients taking abarelix therapy. Abarelix has been associated with QT prolongation and torsade de pointes. Vardenafil is also associated with QT prolongation.
Pharmacotherapy for erectile dysfunction
Both therapeutic and supratherapeutic doses of vardenafil produce an increase in QTc interval. A decreased pressor effect best price on levitra of phenylephrine might occur. Monitor for proper blood pressure when these drugs are used together. Acetaminophen; Dextromethorphan; Guaifenesin; Phenylephrine: (Minor) The therapeutic effect of phenylephrine injection may be decreased in patients receiving phosphodiesterase inhibitors. Acetaminophen; Dextromethorphan; Phenylephrine: (Minor) The therapeutic effect of phenylephrine injection may be decreased in patients receiving phosphodiesterase inhibitors.

Acetaminophen; Guaifenesin; Phenylephrine: (Minor) The therapeutic effect of phenylephrine injection may be decreased in patients receiving phosphodiesterase inhibitors. Acetaminophen; Phenylephrine: (Minor) The therapeutic effect of phenylephrine injection may be decreased in patients receiving phosphodiesterase inhibitors. Adagrasib: (Major) Avoid concomitant use of adagrasib and vardenafil due to the potential for increased vardenafil exposure and additive risk for QT/QTc prolongation and torsade de pointes (TdP). If concomitant use is necessary, use vardenafil oral tablets instead of orally disintegrating tablets and do not exceed a single dose of 2.5 mg per 24-hour period. Additionally, consider taking steps to minimize the risk for QT prolongation and TdP, such as electrolyte monitoring and repletion and ECG monitoring.
Key Takeaways
Vardenafil is a CYP3A substrate, adagrasib is a strong CYP3A inhibitor, and both medications have been associated with QT interval prolongation. Coadministration with other strong CYP3A inhibitors increased the AUC of vardenafil by 10- to 16-fold. Alfuzosin: (Moderate) Due to the potential for symptomatic hypotension, patients should be stable on alfuzosin therapy before initiating therapy with the lowest starting dose of vardenafil. Conversely, patients already receiving an optimized dose of vardenafil should be started on the lowest dose of alfuzosin; 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 alfuzosin.
