Frequently asked questions (FAQ block at the beginning)
What is Vardenafil?
Vardenafil is a prescription medication used to treat erectile dysfunction (ED) in men. It belongs to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by improving blood flow to the penis during sexual stimulation.
How does Vardenafil work?
It enhances the natural response to sexual stimulation by relaxing smooth muscle and increasing blood flow in penile tissue. It does not cause an erection on its own; sexual arousal is still required. Its effect typically begins within 30–60 minutes.
What is Vardenafil used for?
The main indication is erectile dysfunction, which is the consistent inability to achieve or maintain an erection sufficient for sexual activity. In some regions, it may also be evaluated for other vascular-related conditions under medical supervision.
How is erectile dysfunction recognized?
ED is diagnosed when erection problems persist for several weeks or months. Occasional difficulty is common and not necessarily a disorder. If the problem is frequent and causes distress, medical evaluation is recommended.
Why does erectile dysfunction happen?
ED can result from physical causes (diabetes, high blood pressure, heart disease), psychological factors (stress, anxiety, depression), or a combination of both. Lifestyle factors such as smoking and sedentary habits also contribute.
Is Vardenafil safe?
For most healthy men, it is considered safe when prescribed by a doctor. However, it may interact with certain medications, especially nitrates used for chest pain. Medical screening is essential before use.
What are the possible side effects?
Common side effects include headache, flushing, nasal congestion, and indigestion. Less common effects include dizziness or visual disturbances. Serious side effects are rare but require urgent medical attention.
When should I see a doctor urgently?
Seek immediate help if you experience chest pain, sudden vision or hearing loss, or an erection lasting more than four hours (priapism). These symptoms require prompt evaluation.
Can Vardenafil be taken with alcohol?
Small amounts of alcohol may not significantly reduce effectiveness, but excessive drinking can worsen erectile dysfunction and increase side effects like dizziness or low blood pressure.
Is it possible to take Vardenafil daily?
Vardenafil is typically taken as needed before sexual activity. Whether regular use is appropriate depends on individual health factors and should be discussed with a healthcare provider.
Does Vardenafil increase sexual desire?
No. It improves the physical mechanism of erection but does not increase libido. Sexual desire is influenced by hormonal, psychological, and relational factors.
Can younger men use Vardenafil?
It is intended for adult men diagnosed with erectile dysfunction. Use in younger individuals without a medical need is not recommended and should only occur under medical supervision.
Detailed breakdown
1. Mechanism of action and pharmacology of PDE5 inhibitors
Vardenafil belongs to the same class as sildenafil and tadalafil. These medications inhibit the PDE5 enzyme, which regulates blood flow in the penis. By blocking this enzyme, vardenafil enhances nitric oxide effects, promoting vasodilation and improved erectile response.
Compared with other PDE5 inhibitors, it may differ slightly in onset time, duration, and side-effect profile. Choice of medication depends on individual response and medical history.
2. Causes and risk factors of erectile dysfunction
ED is often an early warning sign of cardiovascular disease. Conditions such as atherosclerosis, metabolic syndrome, obesity, and diabetes impair blood vessel function. Psychological contributors include performance anxiety and chronic stress.
Our Creative health awareness section discusses how lifestyle and emotional well-being influence sexual health.
3. Safety considerations and drug interactions
Vardenafil should not be used with nitrates (e.g., nitroglycerin) or certain blood pressure medications due to the risk of severe hypotension. Caution is required in individuals with heart rhythm disorders or significant liver impairment.
Before prescribing, clinicians evaluate cardiovascular fitness for sexual activity. More educational videos on medication safety can be found in our Videos section.
4. Psychological and relationship aspects
Erectile dysfunction is not purely a physical issue. Performance anxiety can create a cycle of stress and worsening symptoms. Open communication with a partner and, when needed, psychological counseling can improve outcomes.
In our 專欄 (Column), experts discuss how mental health connects to sexual performance and confidence.
5. When medical evaluation is essential
Men with new-onset ED, especially under age 50, should consider cardiovascular screening. Sudden changes may signal underlying systemic disease. Persistent or worsening symptoms always justify professional consultation.
| Symptom / Situation | Urgency Level | Where to Seek Help |
|---|---|---|
| Mild headache or flushing | Low | Monitor; discuss with primary care doctor if persistent |
| Dizziness or low blood pressure symptoms | Moderate | Contact healthcare provider promptly |
| Erection lasting more than 4 hours | High (Emergency) | Emergency department |
| Chest pain during sexual activity | High (Emergency) | Call emergency services immediately |
| Sudden vision or hearing loss | High (Emergency) | Emergency medical evaluation |
