Erectile dysfunction is highly common and very treatable. First-line medications are oral tablets called PDE5 inhibitors, which include generic drugs like sildenafil, tadalafil, and vardenafil. These work by relaxing blood vessels to improve blood flow to the penis when you are sexually aroused.Because erectile dysfunction can sometimes be linked to other health factors like stress, high blood pressure, or diabetes, it is important to consult a healthcare provider first. They can safely evaluate your health, check for any drug interactions, and prescribe the correct dosage. Please avoid buying unregulated herbal remedies online, as they can be unsafe.
