Need information on prescription vardenafil? Start by understanding its primary use: treating erectile dysfunction (ED). This medication helps achieve and maintain an erection sufficient for satisfactory sexual intercourse. Its effectiveness depends on several factors, including individual health and the underlying cause of ED.
Vardenafil works by increasing blood flow to the penis. This process involves a complex interplay of enzymes and chemicals in the body. Remember to discuss your medical history with your doctor before starting any treatment. This includes existing heart conditions, liver problems, or any other relevant health issues. They can assess your suitability and determine the appropriate dosage.
Dosage varies, typically ranging from 5mg to 20mg, taken as needed. However, your physician will tailor your treatment plan to your specific needs. Common side effects include headaches, flushing, nasal congestion, and visual disturbances, but these usually are mild and temporary. Always report any unusual symptoms immediately to your doctor. Proper use is crucial, and consistent communication with your healthcare provider ensures optimal results and manages potential risks effectively.

Prescription Vardenafil
Always discuss Vardenafil use with your doctor. They can assess your health and determine the appropriate dosage and potential interactions with other medications you may be taking.
Dosage: Vardenafil comes in various strengths. Your doctor will prescribe the strength most suitable for you, typically starting with a lower dose. Common dosages range from 5mg to 20mg, taken as needed, usually about 30-60 minutes before sexual activity.
Important Note: Do not exceed the prescribed dosage. Taking more than recommended won’t necessarily enhance results and could increase the risk of side effects.
Side Effects: Common side effects include headache, flushing, nasal congestion, and upset stomach. More serious side effects, though less frequent, can include vision changes, hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any serious side effects.
Interactions: Vardenafil can interact negatively with certain medications, particularly nitrates. Inform your doctor about all medications, including over-the-counter drugs and supplements, you are currently using.
Precautions: Vardenafil isn’t suitable for everyone. Men with heart conditions, low blood pressure, or certain eye problems should discuss the risks with their physician before using it. It’s also not recommended for those with a history of stroke or heart attack.
Storage: Store Vardenafil tablets at room temperature, away from moisture and direct sunlight. Keep them out of reach of children.

Understanding Vardenafil’s Mechanism of Action
Vardenafil works by inhibiting a specific enzyme, phosphodiesterase type 5 (PDE5). This enzyme breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule for achieving and maintaining an erection.
By blocking PDE5, vardenafil allows cGMP levels to rise. Increased cGMP relaxes the smooth muscles in the penis, increasing blood flow. This increased blood flow is what leads to an erection.
The process is triggered by sexual stimulation. Sexual stimulation releases nitric oxide, which then triggers the cGMP pathway. Vardenafil enhances this natural process by preventing the breakdown of cGMP.
| Stage | Process |
|---|---|
| Sexual Stimulation | Nitric oxide release |
| Nitric Oxide Action | cGMP production increases |
| PDE5 Inhibition (Vardenafil) | cGMP breakdown slows |
| Increased cGMP | Smooth muscle relaxation |
| Relaxed Muscles | Increased blood flow to penis |
| Result | Erection |
It’s important to remember that vardenafil only works in the presence of sexual stimulation. It doesn’t create spontaneous erections.
Vardenafil Dosage and Administration
The recommended starting dose of vardenafil for erectile dysfunction is 10 mg taken as needed, approximately 60 minutes before sexual activity.
Dosage Adjustments
Your doctor might adjust your dose based on your response and any side effects. Possible adjustments include:
- Increased dose: If 10 mg is ineffective, your doctor may increase it to 20 mg. This should only be done under medical supervision.
- Decreased dose: If you experience significant side effects, your doctor might reduce the dose to 5 mg.
The maximum recommended dose is 20 mg per dose. Do not exceed this amount.
Administration
- Take vardenafil orally with a glass of water.
- It can be taken with or without food, but avoid fatty meals as they may delay absorption.
- Do not take vardenafil more than once a day.
Specific Considerations
Patients with Liver or Kidney Problems
Individuals with liver or kidney impairment may require a lower starting dose. Your doctor will determine the appropriate dosage based on your specific condition.
Always follow your doctor’s instructions carefully. If you have any questions or concerns about vardenafil dosage or administration, consult your physician or pharmacist.
Potential Side Effects and Precautions
Vardenafil, like other PDE5 inhibitors, can cause side effects. The most common include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
More serious, though rare, side effects include sudden vision loss or hearing loss. Seek immediate medical attention if you experience either. Prolonged or painful erection (priapism) requires immediate medical assistance as well. This is a serious condition that needs prompt treatment.
Before starting vardenafil, discuss your medical history with your doctor. This includes any heart conditions, low blood pressure, liver or kidney problems, bleeding disorders, or eye conditions like retinitis pigmentosa. Certain medications may interact with vardenafil, so provide a complete list of all your current prescriptions, over-the-counter medications, and supplements.
Avoid grapefruit juice while taking vardenafil, as it can increase blood levels of the drug. Alcohol consumption may enhance side effects, so moderation is recommended. Follow your doctor’s prescribed dosage carefully and do not exceed the recommended dose.
If you experience any concerning side effects, contact your doctor or pharmacist for advice. They can provide guidance and help you manage any potential issues.
Vardenafil vs. Other Erectile Dysfunction Treatments
Choosing the right erectile dysfunction (ED) treatment depends on individual needs and preferences. Vardenafil, a phosphodiesterase-5 (PDE5) inhibitor, offers a fast-acting option, often producing effects within 30-60 minutes. This contrasts with other PDE5 inhibitors like tadalafil (Cialis), known for its longer duration of action (up to 36 hours), making it suitable for spontaneous intimacy. Sildenafil (Viagra), another common PDE5 inhibitor, provides a similar timeframe to vardenafil.
Comparing Vardenafil’s Side Effects
Side effects vary between these medications. Common side effects for vardenafil include headache, flushing, nasal congestion, and visual disturbances. These are generally mild and transient. Tadalafil and sildenafil share similar side effect profiles, although the frequency and intensity can differ between individuals. Always discuss potential side effects with your doctor.
Beyond PDE5 Inhibitors
Beyond PDE5 inhibitors, other ED treatments exist. Alprostadil, available as injections or urethral suppositories, offers a different mechanism of action. Penile implants provide a long-term solution for severe ED. Lifestyle changes such as diet and exercise also play a significant role in improving ED symptoms. Your physician will help determine the best treatment option based on your medical history and overall health.
