ED medications work by increasing blood flow to the penis to help achieve and maintain an erection.

The safest ED medication depends on the individual's health condition and medical history. Consult with a healthcare professional for personalized advice.

The most effective medication for ED varies from person to person. Common options include Sildenafil (Viagra), Tadalafil (Cialis), and Vardenafil (Levitra).

Common side effects of ED medications include headaches, flushing, upset stomach, and visual changes. Consult with your doctor for a complete list of potential side effects.

Most ED medications are available only with a prescription. However, some over-the-counter supplements claim to improve erectile function, but their safety and effectiveness vary.

Lifestyle changes such as regular exercise, a healthy diet, managing stress, and avoiding smoking and excessive alcohol can help improve erectile dysfunction.
