Hello. Thanks for writing to us.
Levitra is an FDA approved oral medication for erectile dysfunction. It contains Vardenafil an enzyme inhibitor which helps to maintain blood flow in the penis. It is closely related Viagra (sildenafil). The main contraindication of Levitra, is a patient with heart disease who is on treatment with drugs like Nitrates.
Erection even after ejaculation is very limited but is said that the plateau phase between any two cycles of erection is very much reduced. In simple words a man gets his next erection within a very less time when compared to a normal person who is not on treatment. I would like to advise you to maintain a balanced and nutritious diet, avoiding all the risk factors like alcohol and smoking to have a wonderful sexual life.
Hope this helps.
