What Is Erectile Dysfunction?
Erectile dysfunction (ED) is the inability to consistently get or keep an erection that is firm enough for satisfactory sexual activity. Occasional difficulty does not necessarily mean you have ED, but recurring problems are worth discussing with a healthcare professional.
ED is common among men in the United States and becomes more frequent with age, but it is not considered a routine or unavoidable part of aging. It can also be a sign of another health condition, so identifying the underlying cause is an important part of treatment.
What Causes Erectile Dysfunction?
Erectile dysfunction can have physical, psychological, or lifestyle-related causes.
Common contributing factors include:
- Diabetes
- High blood pressure
- Heart and blood vessel disease
- Obesity
- High cholesterol
- Kidney disease
- Hormonal problems
- Nerve disorders
- Certain prescription medications
- Anxiety and stress
- Depression
- Smoking
- Excessive alcohol consumption
- Recreational drug use
Because ED may sometimes be an early sign of cardiovascular or other health problems, persistent symptoms should be evaluated by a healthcare professional.
How Is Erectile Dysfunction Diagnosed?
A healthcare provider may evaluate ED using your:
- Medical history
- Sexual history
- Mental health history
- Current prescription and over-the-counter medications
- Physical examination
- Blood tests or other laboratory testing when appropriate
The goal is not simply to treat the erection problem but also to identify conditions that may be contributing to it.
Common Treatments for Erectile Dysfunction
Treatment depends on the cause of ED, your general health, medications you take, and your personal preferences.
Common approaches include:
- Lifestyle changes
- Oral prescription medications
- Counseling or sex therapy
- Vacuum erection devices
- Injectable or urethral medications
- Hormone treatment when medically appropriate
- Penile implants or other procedures in selected cases
Your healthcare provider can help determine which approach is appropriate for you.
Viagra (Sildenafil) for Erectile Dysfunction
Viagra is the brand name for sildenafil, a prescription medication used to treat erectile dysfunction.
Sildenafil belongs to a class of medicines called PDE5 inhibitors. It works by relaxing certain smooth muscles and increasing blood flow to the penis during sexual stimulation. It does not automatically produce an erection and requires sexual stimulation to work.
Potential Benefits of Viagra
For appropriate patients, sildenafil may:
- Improve the ability to achieve an erection
- Help maintain an erection during sexual activity
- Support sexual confidence
- Provide an on-demand treatment option
Viagra is generally taken before anticipated sexual activity according to the prescribing healthcare provider's instructions.
Cialis (Tadalafil) for Erectile Dysfunction
Cialis contains tadalafil, another PDE5 inhibitor used to treat ED.
Like sildenafil, tadalafil improves blood flow to the penis during sexual stimulation. Tadalafil is available in both as-needed and once-daily treatment regimens for appropriate patients.
Potential Benefits of Cialis
Cialis may offer:
- Improved ability to achieve an erection
- Improved ability to maintain an erection
- Greater flexibility because of its longer duration of action
- A once-daily treatment option for some patients
Tadalafil is also approved for certain men with symptoms of benign prostatic hyperplasia (BPH), which can be an additional consideration when selecting treatment.
Viagra vs. Cialis: What's the Difference?
Both medications belong to the same drug class and work in a similar way, but there are important differences.
| Feature | Viagra (Sildenafil) | Cialis (Tadalafil) |
|---|---|---|
| Active ingredient | Sildenafil | Tadalafil |
| Drug class | PDE5 inhibitor | PDE5 inhibitor |
| Main ED use | Erectile dysfunction | Erectile dysfunction |
| Administration | Oral | Oral |
| Sexual stimulation required | Yes | Yes |
| Duration | Generally shorter | Generally longer |
| Daily option | No | Yes, for appropriate patients |
| Other approved use | — | BPH, in appropriate patients |
Neither medication is universally "better." The appropriate choice depends on your health, treatment goals, other medications, and how you respond to treatment.
How Do Viagra and Cialis Work?
When a man becomes sexually aroused, the body releases chemicals that increase blood flow into the penis.
PDE5 inhibitors help maintain this process by blocking the PDE5 enzyme, allowing blood flow to increase and making it easier to achieve and maintain an erection.
Importantly, these medications do not create sexual desire and do not cause an automatic erection. Sexual stimulation is still necessary.
Other Prescription ED Medications
Viagra and Cialis are not the only prescription treatments available.
Healthcare providers may also prescribe other PDE5 inhibitors, including:
- Vardenafil (Levitra/Staxyn)
- Avanafil (Stendra)
The best medication depends on individual circumstances and medical history.
For men who cannot use or do not respond adequately to oral medications, other treatments may be considered, including injectable medications, urethral medications, vacuum erection devices, and surgical options.
Lifestyle Changes That May Help ED
Medication is only one part of erectile dysfunction management.
Healthy lifestyle changes may improve overall sexual and cardiovascular health.
Consider:
Exercise Regularly
Physical activity supports cardiovascular health and healthy blood circulation.
Stop Smoking
Smoking can damage blood vessels and contribute to erectile problems.
Limit Alcohol
Excessive alcohol consumption can contribute to ED and may interfere with sexual performance.
Maintain a Healthy Weight
Being overweight or having obesity can increase the risk of conditions associated with ED.
Manage Diabetes and Blood Pressure
Good control of diabetes, blood pressure, and cholesterol may help protect the blood vessels and nerves involved in erectile function.
Manage Stress
Anxiety, depression, and relationship stress can contribute to or worsen ED. Counseling may be helpful when psychological factors are involved.
A healthy diet may also reduce the risk of ED or improve symptoms.
Erectile Dysfunction and Diabetes
Diabetes is an important risk factor for ED. High blood glucose, nerve damage, blood-vessel problems, and other complications associated with diabetes can contribute to sexual difficulties.
Men with diabetes who experience persistent erectile problems should discuss them with their healthcare provider. Improving diabetes management and addressing cardiovascular risk factors may be an important part of treatment.
Safety: Who Should Not Take Viagra or Cialis?
PDE5 inhibitors are not appropriate for everyone.
One of the most important safety considerations is the use of nitrate medications.
Men taking nitrates for certain heart conditions should not take Viagra, Cialis, or other PDE5 inhibitors, because the combination can cause a dangerous drop in blood pressure.
Tell your healthcare provider if you have:
- Heart disease
- Low or uncontrolled blood pressure
- A history of stroke
- Kidney disease
- Liver disease
- Blood pressure problems
- Other cardiovascular conditions
- A history of vision problems
- A history of prolonged erections
Also provide a complete list of prescription medications, OTC medicines, vitamins, and supplements you use.
Common Side Effects of ED Medications
PDE5 inhibitors may cause side effects such as:
- Headache
- Flushing
- Indigestion
- Nasal congestion
- Dizziness
Tadalafil may also cause back or muscle aches in some patients, while sildenafil can cause visual changes in some individuals.
Contact your healthcare provider if side effects are persistent or concerning.
Seek emergency medical attention for serious symptoms such as chest pain, severe allergic reactions, sudden vision or hearing changes, or an erection lasting longer than four hours.
Avoid Unapproved Sexual Enhancement Products
U.S. consumers should be cautious about products marketed as "natural" sexual enhancement supplements or products that claim to work like prescription ED medications.
The FDA has recently warned consumers about several sexual-enhancement products found to contain undeclared sildenafil or tadalafil. These hidden ingredients can be particularly dangerous because consumers may unknowingly combine them with medications such as nitrates.
For safety, discuss ED treatment with a licensed healthcare professional and use medications obtained through legitimate, properly regulated channels.
