Handling erectile dysfunction is not as much difficult as you think. People always hide this dysfunction because nobody wants to discuss about ED. It is a male condition that leads to the dissatisfaction if not treated as soon as possible. If this problem is associated with medical conditions then you need to consult with the doctor. In that case, first priority is to treat medical problems first and then start the treatment of ED. Conditions like diabetes, heart diseases, high blood pressure and high cholesterol are the main medical problems that increase the risk of developing erectile dysfunction. As per the medial law, you can take Generic Viagra drug for the treatment of ED. This drug increases the flow of blood in to the reproductive organ. The main reason of erectile dysfunction is inadequate blood supply. I always suggest my users to consult with doctor if you want to alter the dosage of Sildenafil citrate.
