Visual field defect, retinal vein occlusion, retinal artery occlusion, and non–arteritic anterior ischemic optic neuropathy (NAION) Hypersensitivity, including Stevens-Johnson syndrome and exfoliative dermatitis Guanylate cyclase (sGC) stimulators (eg, riociguat); concomitant use can cause hypotension Coadministration with nitrates (either regularly and/or intermittently) and nitric oxide donors Do not use nitrates within 48 hr of the last dose of macitentan/tadalafil This potentiation is thought to result from the combined effects of nitrates and tadalafil on the nitric oxide/cGMP pathway The potentiation is consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway Use caution in patients with anatomic deformation of penis, cardiovascular disease, left ventricular outflow obstruction, myocardial infarction in preceding 90 days, unstable angina, angina occurring during sexual intercourse, NYHA class 2 or greater heart failure in preceding 6 months, uncontrolled arrhythmias, hypotension, uncontrolled hypertension, cerebrovascular accident in preceding 6 months, bleeding disorders, active peptic ulcer disease, liver disease, renal impairment, conditions predisposing to priapism, concomitant use of CYP3A4 inhibitors May cause dose-related impairment of color discrimination; use caution in patients with retinitis pigmentosa Evaluate underlying causes of erectile dysfunction or BPH before initiating therapy Do not use nitrates within 48 hours of last dose of tadalafil Drug has vasodilatory properties that may result in transient decreases in blood pressure; prior to prescribing, carefully consider whether patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects; patients with preexisting hypotension, with autonomic dysfunction, with left ventricular outflow obstruction, may be particularly sensitive to actions of vasodilators When used to treat erectile dysfunction, non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, reported postmarketing; if vision problems arise, discontinue, and contact physician CYP3A4 inhibitors (eg, erythromycin, ketoconazole, itraconazole, indinavir, ritonavir) may significantly increase tadalafil serum levels CYP3A4 inducers (eg, rifampin, St John’s wort) may decrease tadalafil serum levels Potentiates hypotensive effect of nitrates (see Contraindications) Concomitant use with alpha blockers (other than tamsulosin 0.4 mg/day) should be stabilized before initiation of phosphodiesterase (PDE)-5 inhibitors; patients with instability on alpha-blocker therapy alone are at increased risk for symptomatic hypotension with concurrent PDE-5 inhibitor therapy Not to be taken with other PDE-5 inhibitors (eg, sildenafil, vardenafil) Not recommended in patients with pulmonary veno-occlusive disease Advise patients to seek emergency treatment if an erection lasts >4 hr Limited data from case series with use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes Pregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death In animal reproduction studies, no adverse developmental effects were observed with oral administration to pregnant rats or mice during organogenesis at exposures 7 times the exposure at maximum recommended human dose (MRHD) of 40 mg/day based on AUC There are no data on presence of drug and/or its metabolites in human milk, effects on breastfed child, or on milk production; drug and/or its metabolites are present in milk of lactating rats at concentrations approximately 2.4-times that found in the plasma; when a drug is present in animal milk, it is likely that the drug will be present in human milk Controlled studies in pregnant women show no evidence of fetal risk.
