Viagra in profile

In 1998, the United States Food and Drug Administration approved sildenafil citrate for use as an anti-impotence drug. It became available as a prescription drug in the middle of that year, raising hopes for a great number of men who are experiencing a type of impotence known as erectile dysfunction, which refers to the inability of a man to perform sexual intercourse because he cannot achieve or sustain an erection. Since manufactured by the drug giant Pfizer, Inc., analysts expect Viagra to become one of the best-selling drugs in history.

Taken through the oral route of administration, real Viagra tablets affect the body by blocking the production of phosphodiesterase type 5 (PDE5). Nitric oxide is released into the corpus cavernosum, i.e. cavernous spaces, of the penile musculature, after a man becomes sexually aroused. This allows for an increase in the concentration of a chemical compound called cyclic guanosine monophosphate (cGMP), and this chemical enables blood flow into the corpus cavernosum, thus allowing for an erect penis.

Since making its debut, the drug is considered as a better alternative to previous impotence treatments, such as penile implants and injections, which a lot of patients found inconvenient or uncomfortable. However, physicians were quick to point out that the drug would not work for a man whose sexual function was normal.
The high success rate recorded in the use of this drug means there has been a proliferation of websites who now offer the drug to those customers who want to buy Viagra online cheap. However physicians are always quick to point out that the drug, like any other, has some effects. Before any one thinks to buy Viagra with no prescription, it pays to educate oneself on the do’s and don’ts of taking Viagra, as given below.

Do’s and don’ts of taking Viagra.
If you are taking any drug prescribed for chest pain, like nitrates, don’t take Viagra, as this could potentiate a steep and fatal drop in blood pressure.

Don't take VIAGRA if you take nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure.

Do consult with your doctor to discuss your health status to ensure that you are in sound condition to engage in sexual intercourse.
Do seek immediate medical help if you are experiencing discomfort, chest pain or nausea during sex.

In rare situations where priapism occurs, as with any ED tablet, lasting more than four hours, do seek immediate medical help to avoid long-term injury.
Do start with the lowest dose of 25 mg, as would be prescribed by your doctor, if you are over 65 years or you have serious kidney or liver problems.

Do take your doctor’s minimum prescription of 25 mg if you are on protease inhibitors like the treatment for HIV. Also remember that your doctor might want to limit you to just the 25 mg minimum dose during a period of 48 hours.

Do discontinue with taking VIAGRA or any other PDE5 inhibitors when you experience sudden decrease or loss of vision, and see a doctor as soon as possible. This is a rare situation, though, and it’s not quite possible to ascertain if this anomaly is connected to the PDE5 inhibitors or a combination of other factors.

Common side effects of viagra include: headache, stomach upset and facial flushing. Less common ones include blurred vision, bluish vision or sensitivity to light which may occur briefly.
Finally, because ED is a medical condition, it can only improve with treatment. Many men who suffer from the condition are reluctant to discuss it with their doctors. However, they feel less burdened after discussing it.
