There is such a disease that makes it difficult for patients to talk about it, even when they face the doctor, they hide it, and even more reluctant to communicate. It makes men have low self-esteem, lose self-confidence, feel depressed and frustrated, and even affects the relationship between husband and wife, family harmony, social stability; this disease is erectile dysfunction. Erectile dysfunction (commonly known as impotence, English abbreviation ED) refers to normal adult men, the penis can not consistently achieve and maintain sufficient erection to complete a normal sex life, and last for at least 6 months. So occasionally a few times or a small period of time can not achieve the desired sex life can not be called erectile dysfunction. Erectile dysfunction is a common condition among men and is not a scourge. It is estimated that more than 150 million men worldwide have different degrees of erectile dysfunction, of which about 85% need to receive treatment, however, due to various reasons, less than 10% of patients take the initiative to consult the doctor. In fact, we should rationally and correctly look at the disease of erectile dysfunction. First of all, you should find a professional doctor in a regular hospital to make a clear diagnosis and find the cause of the disease as much as possible; then according to the specific situation, targeted treatment. The treatment of erectile dysfunction is just like the treatment of hypertension, diabetes and other chronic diseases, although there is no so-called “miracle drug”, can be both symptomatic and curative, but you can take appropriate treatment methods to control it, improve the quality of life. Currently, for most patients with erectile dysfunction, the preferred treatment is oral medication. The most prominent of these are phosphodiesterase inhibitors, and commonly used drugs include sildenafil, tadalafil, and vardenafil. One of the most familiar drugs is “Viagra”, formerly known as “Viagra” in China, chemically known as sildenafil citrate. This type of drug can achieve the following three points that patients want: sufficient hardness of erection; hardness of lasting erection; can make patients and their partners feel satisfied. So, what should we pay attention to when using this class of drugs? The following is “Viagra” as an example, to explain the points of concern. First, the correct way to use. Any good drugs must have the correct use of methods, in order to maximize the efficacy. Currently, the most common way to use Viagra is to take it on demand, with a recommended dose of 50-100mg, which can be increased or reduced according to efficacy, tolerability and clinical condition. The recommended dose is 50-100mg, which can be increased or decreased depending on the efficacy and clinical condition. The time of taking Viagra is 30 minutes to 1 hour before sexual intercourse, and older patients need to take it 1 hour earlier due to the slow absorption of the drug. The maximum number of doses is 1 per day. Secondly, Viagra is not an aphrodisiac. Some patients mistakenly think that Viagra is an aphrodisiac, which is not the case. “Viagra” is not aphrodisiacs, can not trigger or improve libido after taking, only under sexual stimulation (sexual stimulation is visual and auditory stimulation, kissing, touching, etc.), to help men with erectile dysfunction erection more firm, more durable, to achieve satisfaction and sexual life. Third, about “drug resistance” and “addiction”. Many people are concerned about whether the drug will not work after taking it for a long time. According to the current domestic and foreign research and related reports, it has not been found that Viagra drug resistance phenomenon; many patients can still maintain good results after long-term use. Drug addiction is a chronic, recurring, patients continue to take drugs regardless of the consequences of compulsive behavior, and “Viagra” is not addictive, even if long-term use will not produce drug dependence. Fourth, common adverse reactions. The most common adverse reactions are headache, facial flushing, dyspepsia and muscle pain, followed by nasal congestion, diarrhea, dizziness and skin rashes, a few patients may experience temporary visual color changes (such as the inability to distinguish between blue and green objects), increased sensitivity of the eyes to light, etc. The incidence of these adverse reactions is not high, and is generally short-lived, and most of the time, it can be tolerated and relieved on its own. Fifth, Viagra should not be used in combination with nitrates, otherwise it may cause severe hypotension and adverse effects. Therefore, if you have a “fistula”, you should take the right attitude. On the one hand, in the strategic contempt of the disease, that is, do not worry too much, too worried, too much pressure, should adjust the mentality, enhance confidence, to face the disease, to overcome the disease. On the other hand, the disease should be emphasized tactically, and there is no need to be ashamed of the disease, nor should one hold an indifferent attitude, but should be actively consulted and treated through the correct channels. As long as you take this attitude, combined with the correct treatment methods, you will be able to get back your “sexual happiness” life!
