今天讨论下这个问题，可能男性会比较感兴趣，哈......

伟哥在临床上叫枸橼酸西地那非片，该药有头痛、面部潮红、胃肠不适、视力异常等副作用，吃多了伟哥更容易引发这些副作用。还有勃起可能会超过4小时以上。如果不及时处理，异常的勃起状态可能会对阴茎造成永久性的损伤。如果说服药后有出现视觉异常、听力异常的，应立即停用药品，如果有服用硝酸盐绝对不能同时服用枸橼酸西地那非片，否则会危及生命。伟哥最严重的危害是会导致心肌梗塞、心律失常、脑血栓等心脑血管疾病，因此年老、虚弱、有心脏病的患者谨慎使用。

Viagra in clinical called sildenafil citrate tablets, the drug has headache, facial flushing, gastrointestinal discomfort, vision abnormalities and other side effects, eat more Viagra more likely to cause these side effects. And erections can last more than four hours. If not handled in time, abnormal erectile state may cause permanent damage to the penis. If there are visual and hearing abnormalities after persuasion, the drug should be stopped immediately. If nitrate is taken, sildenafil citrate tablets should not be taken at the same time, otherwise it will be life-threatening. The most serious harm of Viagra is that it can lead to myocardial infarction, arrhythmia, cerebral thrombosis and other cardiovascular and cerebrovascular diseases. Therefore, elderly, weak and patients with heart disease should use it carefully

服用伟哥，一定要在专科医生指导下合理用药。一般仅仅出现面部潮红、心率加快、头晕等一过性药物不良反应，很多患者会担心长期服用伟哥会导致阳痿，这个不必担心，西地那非也就是伟哥是治疗阳痿的正规药物，而不会导致阳痿。还有一些患者担心，如果长期服用伟哥是否有依赖性，这个更不必担心，伟哥只是扩张血管，促进阴茎海绵体充血勃起，长期服用不会像精神类药物有依赖性，因此，只要在医生指导下用药即可。目前常用的伟哥是白云山金戈，性生活前1个小时服用，配合性刺激，10分钟就可以勃起，安全有效不成瘾，准备要宝宝的男性也可以放心服用。

Take Viagra, must be under the guidance of a specialist in the rational use of drugs. Generally, there are only transient adverse drug reactions such as facial flushing, heart rate acceleration and dizziness. Many patients will worry that taking Viagra for a long time will lead to impotence. There is no need to worry about this. Sildenafil is the regular drug for treating impotence, but it will not lead to impotence. There are also some patients worried that if long-term use of Viagra is dependent, this is not to worry about, Viagra just dilates blood vessels, promote penile cavernous hyperemia and erection, long-term use will not be like psychotropic drugs dependence, therefore, as long as under the guidance of a doctor can. At present, the commonly used Viagra is Baiyunshan Jinge. It is taken one hour before sex and can be erect in 10 minutes with sexual stimulation. It is safe and effective without addiction. Men who are ready to have a baby can also take it at ease

首先对于这种药物，需要存在有器质性的性功能障碍，才需要使用此类药物。所以是否有适应症？是否可以使用这类药物，需要专业医生检查以后决定。如果使用不当的话，是有可能加重阳痿早泄的。
