Vilitra you mean vardenafil, it can be used as an occasional, “as-needed” ED treatment in adult men who have difficulty getting or maintaining an erection. Vardenafil is a PDE-5 inhibitor, like sildenafil and tadalafil. F FDA Access Data +1 Who may be a suitable candidate? Generally, an adult man with occasional ED who: Can safely have ***** activity. Isn't taking nitrate medicines for chest pain. Doesn't have unstable heart disease or certain serious cardiovascular conditions. Isn't taking contraindicated medicines such as riociguat. Has had his other medicines and health conditions checked for interactions. F FDA Access Data For occasional use, vardenafil is typically taken when needed rather than every day; clinical guidance lists 10 mg as a common starting as-needed dose, with adjustment based on effectiveness and tolerability. H HWE Clinical Guidance Who should be especially cautious? Talk to a doctor/pharmacist first if you have heart disease, low blood pressure, uncontrolled high blood pressure, liver/kidney problems, or take alpha-blockers for prostate or blood-pressure problems. Vardenafil can lower blood pressure when combined with some of these medicines. F FDA Access Data +1 Never combine Vilitra/vardenafil with nitrates such as nitroglycerin/GTN or isosorbide medicines. This combination can cause a dangerous fall in blood pressure. F FDA Access Data +1 If you're having ED only occasionally, that's often related to stress, tiredness, alcohol, or anxiety, but persistent/recurrent ED can sometimes be an early sign of diabetes, high blood pressure, or cardiovascular disease.
