Possible additive vasorelaxation, leading to low blood pressure. 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 of drug used in combination with other treatments for erectile dysfunction not studied; use of such combinations not recommended Vision loss may occur rarely and may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION); patient should seek medical assistance for sudden loss in one or both eyes; patients who have already experienced NAION are at increased risk of recurrence; use is not recommended in patients with known degenerative retinal disorders May increase risk of rare sudden vision loss attributed to nonarteritic ischemic optic neuropathy; if vision problems arise, discontinue, and contact physician The drug has systemic vasodilatory properties that resulted in transient decreases in supine blood pressure in healthy volunteers (mean maximum decrease of 7 mmHg systolic and 8 mmHg diastolic); while this normally would be expected to be of little consequence in most patients, physicians should carefully consider whether their patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects Physicians should advise patients to stop taking all PDE5 inhibitors, and seek prompt medical attention in event of sudden decrease or loss of hearing; these events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to intake of PDE5 inhibitors, including vardenafil; it is not possible to determine whether these events are related directly to use of PDE5 inhibitors or to other factors CYP3A4 inhibitorsConcomitant administration with potent CYP3A4 inhibitors (eg, ritonavir, indinavir, cobicistat, ketoconazole) or moderate CYP3A4 inhibitors (eg, erythromycin) increases plasma concentrations of drug;

in some patients, concomitant use of these two drug classes can lower blood pressure significantly leading to symptomatic hypotension (eg, fainting)Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor; patients who demonstrate hemodynamic instability on alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitorsIn patients who are stable on alpha-blocker therapy, initiate PDE5 inhibitors at lowest recommended starting doseIn patients already taking optimized dose of PDE5 inhibitor, initiate alpha-blocker therapy at lowest dose; stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure in patients taking a PDE5 inhibitorSafety of combined use of other PDE5 inhibitors and alpha-blockers may be affected by other variables, including intravascular volume depletion and o Coadministration of sepiapterin with drugs affecting nitric oxide-mediated relaxation may cause additive vasodilation and further reduce blood pressure. sertralinesertraline cenforce 200 tablets and vardenafil both increase QTc interval.
