Best Erectile Dysfunction Treatments in 2025
Your path to better performance starts here

The Diagnostic and Statistical Manual, 5th edition, or DSM-5 is the gold standard of medical diagnostic definitions. According to the DSM-5, Erectile Disorder is defined as “the recurrent inability to achieve or maintain an adequate erection during partnered sexual activities. The disorder must persist for at least six months and cause significant distress or interpersonal difficulties. It is not caused by other mental disorders, substance use, or medical conditions”

Erectile dysfunction (ED) is one of the most common sexual health concerns for men, and it’s far more common than many realize. It affects millions of men and can often be a symptom of underlying health issues. In the U.S., a recent nationally representative study (2021 National Survey of Sexual Wellbeing) reported measurable prevalence of ED in 1822 adult men. The likelihood of ED rises with age. It affects a quarter of men over age 45, a third over age 55, and over half over age 75. Interestingly, only 7.7% of men reported a clinical diagnosis of ED, citing a lack of need to see a healthcare provider in the past year as the primary reason. ED is defined as the ongoing difficulty in getting or keeping an erection firm enough for satisfying sex. Seeking medical evaluation is a sign of strength and the critical first step toward improving overall health and quality of life.

While occasional difficulties in achieving erections are normal, persistent ED that lasts for months may be linked to physical factors like cardiovascular disease, diabetes, or hormonal imbalances, as well as psychological factors such as stress, performance anxiety, or depression. The important thing to know is that millions of men are affected, and they are not alone as there are effective, safe, modern medical treatments available.

This guide answers the most common questions men have about ED medications, explaining how they work, what to expect, and how to choose the right option with your healthcare provider for your health and lifestyle.

Yes, absolutely. ED can signal early cardiovascular disease, diabetes, low testosterone, prostate issues, or hormonal imbalance. It is also often linked to poor blood vessel health or circulation, particularly in older men. A thorough medical evaluation performed by a healthcare professional at the time of an ED diagnosis may help uncover and address broader health risks.

Erectile dysfunction pills are the most common, effective, and first-line treatment options for men who experience difficulty achieving or maintaining an erection. They belong to a class of drugs called Phosphodiesterase type-5, or PDE5, inhibitors, which includes sildenafil (Viagra), tadalafil (Cialis), and avanafil (Stendra). These three medications are the only FDA-approved ED pills in this class, and they work by dilating smooth muscles in the lining of blood vessels supplying the penis, as well as arterioles in the lungs - sildenafil and tadalafil are also FDA-approved for the treatment of pulmonary hypertension, and have shown cardiovascular benefits beyond treatment of ED symptoms. By inhibiting PDE5, the drugs increase circulation and improve erectile function — but only in response to sexual stimulation.

Unlike natural remedies that lack scientific, peer-reviewed, randomized-controlled clinical research studies that rigorously test for safety and efficacy consistent testing, prescription ED pills are clinically proven and FDA-approved. The three approved medications are:

• Sildenafil (Viagra) Released in 1998 by Pfizer, available as generic since 2018. → fast onset, within typically 30–60 minutes, duration of 4-6 hours. Doses range from 25-100mg. It is used when the time is right, and is the prototype of the trio.
• Tadalafil (Cialis) Released in 2003 by Eli Lilly, available as generic since 2018. → onset within 30-60 minutes, duration of 24-36 hours. Doses range from 2.5mg-5mg daily, or 10-20mg as needed. It is also approved for the treatment of benign prostatic hypertrophy, or BPH. It is used for daily dosing for anytime readiness, and is known as the longest-acting of the trio, earning it the nickname “the weekend pill.”
• Avanafil (Stendra) Released in 2012 by Vivus, available as generic since 2024. → onset within 15-30 minutes, duration of 6-12 hours. Men are able to have sex within 15 minutes of taking it. It is used when intimacy is imminent, and is known for being the fastest-acting of the trio.

The choice between them depends on lifestyle, timing preferences, and medical conditions.

There is no universal “best ED pill.” The choice depends on individual needs:

• Sildenafil (Viagra) is the first one discovered and has the longest history of safety and efficacy. It is effective for most men who want reliable, short-term support.
• Tadalafil (Cialis) has also been around for a long time and has been extensively studied for safety and effectiveness as well. It is popular with men who prefer spontaneity, as it lasts longer and can be taken daily.
• Avanafil (Stendra) is valued for its quick onset, useful for those seeking flexibility. It is the newest of the bunch, but has still been around long enough to ensure safety and effectiveness.

Other ED treatments are considered second- or third-line options when ED pills are ineffective. These include:

• Penile injections → powerful but invasive, often the first choice used when pills fail.
• Vacuum erection devices → non-drug alternative, effectiveness varies widely based on proper technique and individual differences.
• Lifestyle changes → regular physicals and mental health check-ups, quitting smoking, weight loss, stress management, and exercise can greatly improve erectile function.

Ultimately, the “best” treatment is the one that balances effectiveness, convenience, safety, and cost for each man. Treatment effectiveness also depends significantly on current health conditions and incorporating lifestyle changes.

The primary benefit of erectile dysfunction pills is obvious: stronger, more reliable erections by physiological stimulation of smooth muscles in the penis to increase blood flow. ED medications have numerous benefits:

• Restore sexual confidence and reduce performance anxiety.
• Improve relationship satisfaction and intimacy.
• Encourage men to seek medical advice, which can reveal hidden or uncontrolled medical conditions like heart disease or diabetes.
• Provide flexibility in sexual timing (especially with tadalafil, the cialis generic option that lasts up to 36 hours).
• Daily dosing with tadalafil, as-needed dosing with sildenafil, or fast-acting responsiveness with avanafil are all available first-line treatment options.

ED medications are also used to treat pulmonary hypertension, benign prostatic hypertrophy, and have recently been shown to have cardiovascular benefits with regular use. Current studies are evaluating whether this improvement is the result of increase in physical activity with ED pill use, or the medications themselves. Preliminary results are strong that whatever the reason, ED pills can lead to improved cardiovascular function. Again, always consult with a medical professional before beginning any kind of ED regimen.

For many men, these benefits improve quality of life as much as physical performance.

When prescribed by a licensed healthcare provider, ED medications are generally safe and effective. The most common side effects are mild and temporary, and often resolve over time with consistent use. The most common side effect is headache, with a prevalence of 22%, 10%, and 7% for Viagra, Cialis, and Stendra respectively. The only other common side effects, (greater than 2% of patients) are found only in Viagra. These include facial flushing 14%, dyspepsia (indigestion) 11%, nasal congestion 7% and blue-tinted vision 7%. Rare side effects include back pain, muscle pain, nausea, and dizziness, headaches, facial flushing, nasal congestion, indigestion, or visual changes such as a blue tint.

Important Safety Considerations

ED pills are not safe for everyone. It is critical to be honest with your medical provider about your current health conditions, medications, and medical history. ED pills can cause dangerous interactions with certain heart medications, particularly nitrates or alpha-blockers taken for chest pain. They may also interact with other medications that are used to treat pulmonary hypertension. Men with uncontrolled or advanced cardiovascular disease, uncontrolled diabetes, severe kidney problems, severe liver disease, or recent history of strokes, orthostatic hypotension or a history of falls, fainting, or dizziness should not only take these medications.

Never buy ED pills without a prescription. Counterfeit pills sold online without proper authorization are a significant danger. To obtain ED pills online safely, always ensure your prescription comes from a licensed telehealth provider or pharmacy. Counterfeit ED pills sold without prescription are common, and may contain unregulated or harmful ingredients, incorrect dosages, or no active medicine at all.

The onset time depends on the pill type, food intake, and metabolism.

This variability in onsets and durations of action is why some men try different ED medications before finding the one that suits them best. Importantly, ED pills do not cause spontaneous erections — sexual stimulation is still required.

No, in the United States, a prescription is required to buy erectile dysfunction (ED) pills such as sildenafil (Viagra), and tadalafil (Cialis), and avanafil (Stendra). These medications are regulated by the FDA to ensure they are used safely, at the correct dosage, and without harmful drug interactions.

For those looking for convenience, it is possible to obtain ED from telehealth providers. These services conduct virtual consultations with licensed healthcare professionals and can send prescriptions directly to verified, licensed pharmacies.

IMPORTANT NOTICE: Avoid websites that sell “cheap Viagra” or “generic Cialis” without a prescription. These are unregulated and contain unsafe or counterfeit ingredients.

Telehealth has made it easier than ever to access ED treatment. Here’s how the process typically works:

1. Research Legitimate Websites: Must have all of the following: telehealth consultation with a licensed medical provider, a verified, legal prescription, and dispensing of medications from a licensed pharmacy.

2. Consultation: Online or in-person with a healthcare provider. It is more convenient to have a telehealth consultation, as a physical examination is not required to establish a diagnosis.

3. Medical review: Doctor checks your health history, current medical conditions, list of current medications, and health goals.

4. Prescription: If suitable, you’ll receive a prescription for one of the three FDA-approved medications: Viagra online, Cialis online, or Stendra. another ED medication.

5. Pharmacy delivery: Medications are shipped in discreet packaging from licensed US pharmacies. The packages are typically in blank, standard packages with a generic company name and no external indication of the contents.

When purchasing ED meds online, always verify that the provider is US-licensed and board-certified. Avoid websites that don’t require a consultation or prescription with a licensed, U.S. based provider — they are a red flag for counterfeit products. Avoid sellers you don’t know, and check for business reviews and Better Business Bureau scores. Some reputable online providers, without endorsing any in particular, are Ro, Hims, Rugiet, PeterMD, and Blue Chew.

ED is usually not permanent. The majority of cases can be managed or reversed by addressing underlying causes such as lifestyle choices, exercising, avoiding alcohol and smoking, weight loss, and managing high blood pressure, diabetes, or hormonal imbalances like hypothyroidism or hypogonadism. Psychological factors like clinical depression and performance anxiety also play a role and are likely to improve with psychotherapy or counseling with licensed professionals.

Many men experience lasting improvement when combining ED pills with lifestyle changes. For example, exercising regularly and improving diet by decreasing intake of saturated fats and cholesterol, limiting alcohol, quitting smoking, and managing current health conditions not only supports erections but also reduces cardiovascular risks. In this way, ED treatment can serve as an early warning system for broader men’s health.

While ED pills are effective, combining them with lifestyle adjustments massively enhances results:

• Exercise → Increases blood flow, cardiovascular health, and elevates testosterone.

• Diet → Reducing saturated fats, sugar, and increasing whole foods consumption like fresh vegetables, complex carbohydrates like rice and pasta, and protein from meats, dairy products, or legumes improves circulation.

• Sleep → Improving sleep quality and hygiene increases testosterone and reduces symptoms of ED.

• Stress management → Addressing anxiety and depression symptoms through psychotherapy or medication can enhance the block response to ED meds.

• Limit alcohol and quit smoking → Both directly impair erectile function. Ideally, abstain from both.

ED treatment is significantly more effective when medical and lifestyle approaches are combined.

Yes. Excessive alcohol can lower blood pressure, and increase the risk of side effects such as dizziness or fainting. It also weakens erections and reduces pill effectiveness. Avoiding or limiting drinking alcohol is strongly advised when taking sildenafil or tadalafil.
