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 are more reluctant to communicate. It makes men feel inferior, lose self-confidence, frustrated and defeated, and even affects the relationship between husband and wife, family harmony, and social stability; this disease is erectile dysfunction. Erectile dysfunction (commonly known as impotence, abbreviated as ED) is the inability of the penis to consistently achieve and maintain an erection sufficient to complete a normal sexual life for at least six months in normal adult men. So a few times or a small period of time when you can’t achieve an ideal sex life is not called erectile dysfunction. Erectile dysfunction is a common condition among men and is not a flood. It is estimated that more than 150 million men worldwide have varying degrees of erectile dysfunction, and about 85% of them need to be treated, yet less than 10% of patients actively seek medical attention for various reasons. In fact, we should look at the disease of erectile dysfunction in a rational and correct way. First of all, you should find a professional doctor in a regular hospital to make a clear diagnosis and find the cause as much as possible; then, according to the specific situation, targeted treatment. The treatment of erectile dysfunction as the treatment of hypertension, diabetes and other such chronic diseases, although there is no so-called “miracle drug”, to be able to a little bit of both the symptoms and the root cause, but 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. Among them, the most important is phosphodiesterase inhibitors, commonly used drugs include sildenafil, tadalafil, vardenafil, etc.. 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 things that patients want: an erection of sufficient hardness; an erection that lasts; and satisfaction for the patient and his or her partner. So, what should we be aware of when using this class of drugs? The following is an explanation of the points of concern, taking Viagra as an example. First, master the correct method of use. Any good drug must have the correct method of use, in order to play the maximum efficacy. The most common way to use Viagra is to take it on demand, with the recommended dose of 50-100mg, which can be increased or reduced according to efficacy, tolerance and clinical condition. The recommended dose is 50-100mg, which can be increased or decreased depending on efficacy, tolerance and clinical condition. The dose should be taken 30 minutes to 1 hour before sex, and 1 hour earlier for older patients due to slow absorption of the drug. The maximum number of doses is one per day. Secondly, Viagra is not an “aphrodisiac”. Some patients mistakenly believe that Viagra is an aphrodisiac, but this is not the case. “Viagra is not an aphrodisiac, it cannot trigger or increase sexual desire after taking it, but only works under sexual stimulation (sexual stimulation includes audio-visual stimulation, kissing, touching, etc.), helping men with erectile dysfunction to have firmer and longer-lasting erections and achieve a satisfying 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 current domestic and international research and related reports, no drug resistance has been found to occur with Viagra; many patients can still maintain good results with long-term use. Drug addiction is a chronic, relapsing, compulsive behavior of patients who continue to take drugs regardless of the consequences, while 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, indigestion and muscle pain, followed by nasal congestion, diarrhea, dizziness and skin rash, and temporary visual color changes (such as inability to distinguish between blue and green objects) and increased sensitivity to light in a few patients. Fifth, Viagra should not be taken in combination with nitrates, as this may cause severe hypotension and adverse consequences. Therefore, if you have a case of “fistula”, you should take the right attitude. The actual fact is that you will be able to get a good deal on your own, and you’ll be able to get a good deal on your own. On the other hand, tactically, we should attach importance to the disease, and we should not be ashamed of it, nor should we hold an indifferent attitude, but should actively seek medical consultation and treatment through the right way. As long as you take such an attitude, combined with the correct treatment, you can get back your “sex life”.
