There are several medications available for the treatment of erectile dysfunction, including Viagra by Pfizer, Levitra by Bayer, and Cialis by Nippon Shinyaku. Recently, a variety of generic drugs have also been released, providing a wide range of options. Each medication has its own characteristics, so please use them after understanding them thoroughly. The effects of these medications typically appear about 30 minutes after ingestion. Levitra has the characteristic of faster onset compared to Viagra, with effects lasting for 3 to 5 hours. In the case of Cialis, effects appear after about 3 hours and last for approximately 36 hours.
Precautions for Taking
Taking the medication after a meal may reduce its effectiveness, so it is recommended to take it on an empty stomach. Heavy alcohol consumption can also diminish its effectiveness. Reported side effects of the medication may include facial flushing, eye redness, headaches, and nasal congestion, but these are usually mild and tend to disappear relatively quickly. Be sure to strictly adhere to the prescribed dosage.

Have You Ever Felt That ED Medications Are Less Effective Than Before?
Treatment with ED medications stimulates the secretion of substances that promote erection in the endothelial cells of the penile corpus cavernosum. However, when these crucial endothelial cells deteriorate due to aging, the secretion of erection-promoting substances becomes insufficient, resulting in a perceived decrease in the effectiveness of the medication.
In such cases, treatments that regenerate and repair aging endothelial cells, such as stem cell cultured supernatant extract therapy or RENOVA, can be effective in restoring function.
