Vigore 100 is a medication containing sildenafil citrate, primarily used to treat erectile dysfunction (ED) in men. It works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual stimulation, which helps achieve and maintain an erection. Limit alcohol consumption and avoid grapefruit or grapefruit juice, as these can interact with sildenafil and increase the risk of side effects. Always follow the guidance of a qualified healthcare professional when using medications like Vigore 100. Do not self-medicate or adjust the dosage without professional advice.
