The first question that comes in mind of most men before starting the treatment for impotence is which medication is most effective. It is quite confusing to decide as there are many options available for erectile dysfunction treatment. Most probably the once to choose from will be the most popular of the PDE – 5 inhibitors: Viagra, Cialis and Levitra. These are FDA approved prescription oral treatment for erectile dysfunction. These all three work in exactly same way by inhibiting PDE – 5 enzymes, thereby increasing the flow of blood into the penis. Most probably sexual health professionals will advise Cialis as its effect lasts for 36 hours compared to 4-5 hours of Viagra and Levitra and also starts working quickly. Sexual stimulation is required for all the three to show their effect. The side effects of all the three are almost same. Headache, flushing, indigestion, dizziness are some of the common side effects. Cialis is available in smaller dosage than Viagra that means it will have less severe side effects than Viagra. Viagra, Cialis and Levitra should not be taken if taking nitrates or any medicines containing nitrates.
It is difficult to say which is better than other among Viagra, Cialis and Levitra since all of them are medication of same nature with not too many differences in their chemical formula.
