The purpose of this article is to enlighten all the new users or potential users of Viagra , so that they know exactly what to expect from the product.

The first point in this regard is to know the exact indication, for which Viagra is consumed. It is recommended for use for the treatment of erectile dysfunction, or ED, or sometimes called male impotence. This is a common condition, affecting men of all age, where the concerned individual is unable to get and preserve an erection, which makes sexual intercourse a near impossibility.

Now that the fundamental facts about Viagra have been cleared, let us start to discuss more about the product. How can Viagra ensure that you have erection? This is primarily due to its main ingredient, Sildenafil. Erection is a phenomenon, which happens when there is adequate blood flow in the penile area. Viagra encourages increased blood flow in the penis, by releasing some chemicals in the body, which results in successful erection and maintenance along with sexual arousal. Viagra is to be taken approximately one hour before the sexual act, and the dose is not to exceed more than once a day. The particular dosage may vary according to your specific health conditions, which can only be assessed by a medical practitioner. Since individual dosing needs vary, Viagra is conveniently available in multiple strengths: 25mg, 50mg and 100mg. It is important to note, that purchase of Viagra must be preceded by a prescription from a doctor. This is not an over the counter drug, and consequently a prescription is compulsory.

These include headaches, stomach pain and temporary visual problems including blurred vision. Viagra may have adverse drug interactions with certain hypertension drugs, therefore you ought to discuss with your doctor all such details, before you start taking Viagra.
