Vilitra 60 mg requires sexual stimulation to help produce an erection. Vilitra contains vardenafil, which helps increase blood flow to the penis during sexual arousal. It does not automatically cause an erection and does not increase sexual desire. Without stimulation: It generally will not produce an erection on its own. With stimulation: It may help you achieve and maintain an erection. Duration: Vardenafil Vilitra 60 mg works for around 4–5 hours, although this varies. Safety: 60 mg exceeds the usual maximum recommended vardenafil dose of 20 mg once daily. Higher doses can increase the risk of headache, dizziness, low blood pressure and other adverse effects. Do not take 60 mg without medical advice. Never combine vardenafil with nitrate medicines, such as nitroglycerin. Have you already taken Vilitra 60 mg, or are you considering taking it?
