Viagra and its Precautions


What is Viagra?

Viagra relaxes muscles and increases blood flow to particular areas of the body.

Sildenafil under the name Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women.

Sildenafil may also be used for purposes other than those listed here.

Precautions for Viagra...

Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers). Taking Viagra with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack. If you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw during sexual activity, stop and call your doctor right away. You could be having a serious side effect of Viagra. Do not take Viagra more than once a day. Allow 24 hours to pass between doses. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

A small number of patients have had a sudden loss of eyesight after taking Viagra. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. It is not clear whether Viagra is the actual cause of such vision loss. Sudden vision loss with Viagra use has occurred most often in people with heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old.

Stop using Viagra and get emergency medical help if you have sudden vision loss.

Take extreme precautions while accosting with such medicines. Always prefer some well established and a well known online pharmacy like netpharmaworld.

Viagra is one of the best known pills for erectile dysfunction but is also said to reduce men's fertility by decreasing the ability of their sperm to fertilize an egg. Do not buy viagra without a doctor prescription.

Viagra has been clinically shown to improve erectile function even in men who had diabetes or prostate surgery. The pill contains this component that helps increase blood flow to the penis and may help men with ED get and keep an erection satisfactory for sexual activity.

I went to an online pharmacy a month ago to Buy Lipitor
, Lipitor (Atorvastatin) is an oral drug that lowers the level of cholesterol in the blood.
Hydrocodone Online
is one of the most commonly abused prescription pain medications today. One of the most widely prescribed medications, Cheap Vicodin
and its related medications, loricet, loritab percodan, and oxycontin are opioid-based pain medications. Cheap Hydrocodone
is a derivative of opium, which is also used to manufacture heroin. Individuals with a Vicodin addiction become deeply depressed, and their thinking, attention, and judgement become impaired. Their thoughts dwell on the next high, although they tell themselves they are still taking Vicodin for pain or to avoid the withdrawal symptoms. Individuals with a Vicodin addiction often truly feel physical pain, but it is psychologically produced.
