Erectile dysfunction is a condition that affects millions of men over forty and even younger every year. This has to do with a number of factors, including lifestyle choices, mental stress and physical health, as well as ecological situation and many other ones. Erectile dysfunction is described as a man's inability to attain and keep an erection for long enough to have sex. The problem may also lie in the fact the erection achieved is not hard enough, or cannot be attained at all. While there are some cases when impotence (as erectile dysfunction is commonly referred to) is temporary, because of the patient taking some drugs or undergoing a surgery, in most cases it's for life and needs to be treated. The good news is that erectile dysfunction is easily treatable in most situations, and Viagra is currently one of most popular and efficient medications for that.
Erectile dysfunction is caused by insufficient blood flow to the tissues of the penis, which prevents the male from obtaining or keeping an erection for the period of time desired. Viagra works by targeting the very cause of this problem. It stimulates the blood flow to the tissues of the penis and prevents premature outflow of the blood, which results in harder and more durable erections. In order for Viagra to work, a certain amount of sexual stimulation has to be provided. The effects of Viagra usually last for up to 5 hours, although it's generally recommended to attempt having sex in an hour from the moment the drug was taken.
Viagra has gained international fame because of its amazing efficiency and few mild side effects that are displayed in only a small percentage of patients using it. Such side effects as dizziness, upset stomach, stuffy nose, upset stomach, headache and flushing are uncommon and tend to be short-lived. Viagra is supposed to be taken on the as-needed basis, but not more often than every 24 hours. A suitable dose for each patient may vary, commonly ranging from 25 mg to 100 mg, and can depend on the patient's age, general state of health and individual needs.
