Erectile dysfunction is a condition in which a man has repeated difficulty getting or keeping an erection firm enough for sexual activity. Occasional problems can happen because of stress, fatigue, alcohol, anxiety, or temporary health changes. ED becomes a medical concern when it happens regularly, affects confidence, or starts interfering with intimate life.
The condition is often connected with blood flow, nerve function, hormones, medication use, or emotional health. In many men, erectile dysfunction develops together with high blood pressure, diabetes, high cholesterol, excess weight, smoking, heart disease, or reduced physical activity. This is why doctors often treat ED as more than a sexual problem. It can be an early sign that the cardiovascular system, metabolism, or hormone balance needs attention.
Common Treatment Options
In the United States, erectile dysfunction treatment is mainly based on FDA-approved prescription products, with one newer OTC device option. The main oral medicines are PDE5 inhibitors: Sildenafil sold as Viagra, Tadalafil sold as Cialis, Vardenafil products, and Avanafil sold as Stendra.
The American Urological Association states that men with ED should be informed about FDA-approved oral PDE5 inhibitors unless contraindications apply, with shared decision-making based on onset, duration, adverse effects, and patient priorities.
These products differ mostly by timing and duration. Sildenafil and Vardenafil are usually taken before sexual activity. Tadalafil can be taken as needed and is also used once daily in selected patients, with labeling showing an effect for up to 36 hours after dosing. Avanafil is another as-needed PDE5 inhibitor indicated for adult males with ED.
For men who cannot use oral PDE5 inhibitors or do not respond well enough, FDA-labeled Alprostadil products are available. Edex, an Alprostadil injection, is indicated for ED caused by neurogenic, vasculogenic, psychogenic, or mixed factors, while Caverject is another intracavernosal alprostadil product used in ED treatment and diagnostic testing.
The main non-prescription option is Eroxon, a non-medicated topical gel. FDA authorized Eroxon for marketing in 2023 as the first OTC gel intended to treat ED in adult males aged 22 and over. It is regulated as a medical device rather than an oral drug. ED products should be selected after medical review, especially in men using nitrates, riociguat, alpha-blockers, heart medicines, or products marketed as “male enhancement,” because FDA has repeatedly found undeclared sildenafil or tadalafil in such supplements.

Prevention and Long-Term Control
Preventing erectile dysfunction usually starts with the same habits that protect the heart and blood vessels. Regular physical activity, weight control, smoking cessation, better sleep, limited alcohol use, and a balanced diet can improve general health and may support erectile function over time. Men who already have diabetes, high blood pressure, or high cholesterol should keep those conditions under medical control. ED treatment works best when the underlying health picture is reviewed, not when the symptom is treated in isolation. A medical consultation is especially important if erectile problems appear suddenly, follow chest pain or shortness of breath, or occur together with new medication use.
