Possible additive vasorelaxation, leading to low blood pressure.

  • Vardenafil is sometimes used off-label for other circulatory issues.

  • Always read the medication guide before use.

Soluble guanylate cyclase (sGC) stimulators (eg, riociguat); concomitant use can cause hypotension Coadministration with nitrates (either regularly and/or intermittently) and nitric oxide donors Consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate pathway, PDE5 inhibitors may potentiate the hypotensive effects of nitrates A suitable time interval following PDE5 dosing for the safe administration of nitrates or nitric oxide donors has not been determined Use with caution in anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie’s disease), cardiovascular disease, left ventricular outflow obstruction, bleeding disorders, active peptic ulcer disease, liver disease, renal impairment, multidrug antihypertensive regimens, retinitis pigmentosa, concomitant use of CYP3A4 inhibitors, patients who have conditions that may predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia) There have been rare reports of prolonged erections >4 hr and priapism (painful erections greater than 6 hours in duration) for this class of compounds, including vardenafil; in the event that an erection persists >4 hours, the patient should seek immediate medical assistance; if priapism is not treated immediately, penile tissue damage and permanent loss of potency may result Physicians should consider the cardiovascular status of their patients; there is a degree of cardiac risk associated with sexual activity; treatment for erectile dysfunction, should not be used in men for whom sexual activity is not recommended because of their underlying cardiovascular status Patients with left ventricular outflow obstruction, (for example, aortic stenosis and idiopathic hypertrophic subaortic stenosis) can be sensitive to the action of vasodilators including PDE5 inhibitors Until further information available, use is not recommended in unstable angina; hypotension (resting systolic blood pressure of <90 mmHg); uncontrolled hypertension (>170/110 mmHg); recent history of stroke, life-threatening arrhythmia, or myocardial infarction (within last 6 months); severe cardiac failure Consider counseling patients about protective measures necessary to guard against sexually transmitted diseases, including Human Immunodeficiency Virus (HIV); drug offers no protection against sexually transmitted diseases Patients taking Class 1A (eg, quinidine, procainamide) or Class III (eg, amiodarone, sotalol) antiarrhythmic medications or those with congenital QT prolongation, should avoid using drug Safety and efficacy
