Vidalista helps men who have difficulty achieving or maintaining an erection during sexual activity. Tadalafil belongs to a group of medicines called PDE5 inhibitors. It works by relaxing blood vessels and increasing blood flow to the penis when sexual stimulation occurs. Never combine Vidalista with nitrate medicines such as nitroglycerin, as this can cause a dangerous drop in blood pressure. Consult a doctor before use if you have heart disease, low blood pressure, or take medicines for blood pressure. Seek urgent care for chest pain, sudden vision or hearing loss, or an erection lasting more than four hours. https://www.genericday.com/vidalista.html
