About Viagra (Sildenafil)

What is Viagra?

Sildenafil is sold as Viagra among other trade names. It is a treatment used to treat erectile dysfunction and pulmonary arterial hypertension. It is unclear whether it is used for sexual enhancement among women.

It was discovered by Pfizer scientists Andrew Bell, Nicholas Terrett, and David Brown. It was first available in 1998. Its common competitors in the market include tadalafil (cialis) and Vardenafil (Levitra).

The medical uses of Viagra are varied. As afore-stated, Viagra is commonly used to treat erectile dysfunction among men. Erectile dysfunction is the inability to sustain a satisfactory erection. It is a globally recognized treatment for erectile dysfunction including diabetes.

As noted in the first sentences of this article, Viagra is also used in the treatment of pulmonary hypertension. It eases the condition by relaxing the walls of the arteries, thus decreasing the arterial pressure and resistance. It therefore reduces the workload of the right ventricle and thus improves the symptoms of right-sided heart failure.

Again, people taking antidepressants may sometimes experience erectile dysfunction. This could be as a result of the depression itself or the treatment done on them. A study successfully undertaken in 2003 indicated that Viagra (Sildenafil) had the ability to alleviate such sexual inability. The researchers were also able to conclude that the drug had the capacity to cure the same problem among women.

Finally, Viagra (Sildenafil) is an internationally sanctioned treatment for altitude sickness. It is not only used to address for this problem but also prevents it. As such, mountain climbers usually have this drug administered on them before the start of their message.

How to Use Viagra

Before you take Viagra to enhance your sexual function, make sure you are sexually stimulated. You will not get an erection simply because you have consumed this drug. Again, you should take Viagra at an hour before sexual intercourse. It may however be taken between 30 and 4 hours before sexual activity.

You should not take the drug if you are experiencing chest pain. Again, you should avoid the product if you have respiratory or cardiac complications. If you have been found to be allergic to Sildenafil, you must not take the drug.

Side Effects

Overdose of Viagra can lead to serious health implications. One of serious conditions reported by previous users include priapism. Priapism is a situation in which your erection refuses to go. Note that an erection that stays for more than 4 hours can easily damage your penis. As such, you are advised to seek the help of a doctor in case you experience this side effect.

Even more serious than priapism, overdose of Viagra can lead to sudden loss of eyesight. This could be one eye or both. This could be a sign of a more severe problem known as non-arteritic anterior ischemic optic neuropathy. Therefore, you should seek the attention of a medical practitioner shortly after you discover that your eyes have a problem.

Note that the above side effects may not be only as a result of Viagra overdose. They may occur if the drug reacts against one’s body. This means that you should seek the nod of a qualified medical professional before using this drug.
