Hebei reader Li Wei wrote a letter inquiring: I am 62 years old and have been persisting in sexual activity. The doctor prescribed me Viagra and it worked very well. But in the past month, I don't think taking Viagra has had much effect. Should I increase the dosage or change the dressing? Is it normal for the medication to suddenly fail?
Guo Jun, chief doctor of andrology in Xiyuan Hospital of the China Academy of Chinese Medical Sciences, replied: The scientific name of "Viagra" is PDE-5 inhibitor, which is the first-line drug for erectile dysfunction (ED) treatment at home and abroad. Common drugs include Viagra (sildenafil), Xieli (Tadanafil), Alida (Vardanafil), etc.
There is currently no evidence to prove that Viagra can develop drug resistance. Generally speaking, drug resistance refers to the need for patients to increase their drug dosage to achieve therapeutic effects when taking medication. Most ED patients who take Viagra 1-2 times orally will have good results. If the medication is ineffective, it is necessary to promptly identify the cause.
Firstly, it is necessary to take the medication correctly, and it should be taken as needed 30-60 minutes before * *; Adequate sexual stimulation is necessary; Try to avoid high-fat diets and alcohol consumption; Avoid taking medication with insufficient dosage. For example, if you take 50mg of Viagra and the effect is not significant, you can try 100mg, but you can only take it once a day.
Secondly, 'only good health leads to good sexual function', actively adjusting unreasonable lifestyles, engaging in physical exercise, and cultivating a good lifestyle. Especially the elderly should actively control and treat the primary diseases, such as hypertension, hyperlipidemia, diabetes, prostatic hypertrophy, etc. Research has shown that controlling the above risk factors can enhance the efficacy of Viagra drugs.
Finally, when encountering ED, it is important to have early examination, diagnosis, and treatment, and not to avoid seeking medical attention. If trying to take Viagra is ineffective, seek medical attention at a large hospital. Do not trust small advertisements or seek medical attention in case of emergency.
