Baiyunshan Jingo is the trade name and generic name of sildenafil citrate tablets, which can be used to treat erectile dysfunction. While the severity of male erectile dysfunction and the treatment plan are different, there will be individual differences in the time between medications, and the interval can be one day, one week, one month, or even a longer period of time. If sildenafil citrate tablets are mild, the vast majority of patients will take them as needed, one hour before sexual intercourse, which can improve penile hardness and erection time, and the medication is usually not regular, with irregular intervals. If erectile dysfunction is more severe, the intervals will need to be adjusted according to drug resistance and erection improvement. Generally, the medication can be used every other day at the beginning, or the interval can be increased appropriately, such as once a week or once a month. Because of the individual differences in the effectiveness of the drug treatment, the specific circumstances need to strictly follow the doctor’s instructions.
