Levitra Professional (Vardenafil) – Patient Guide (Australia)

Levitra Professional contains vardenafil, a medicine used to treat erectile dysfunction (ED) in adult men. This guide explains how it works, how to use it effectively, what to expect, and important safety information—written in a patient-friendly way for people in Australia.

Basic product information

• Medicine name: Levitra Professional
• Active ingredient: Vardenafil
• Common purpose: Helps men achieve and maintain an erection suitable for sexual activity
• How it works: Improves blood flow to the penis in response to sexual stimulation
• Available strengths: Common vardenafil strengths include 5 mg, 10 mg and 20 mg (availability may vary by product and supplier)

Levitra Professional is intended for adult men. It is not suitable for women or children.

How Levitra Professional works (mechanism of action)

Erectile dysfunction often involves reduced blood flow to the penis. Vardenafil belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors.

During sexual arousal, the body releases nitric oxide, which increases levels of cyclic GMP in penile tissue. Cyclic GMP relaxes smooth muscle and allows increased blood flow. PDE5 is an enzyme that breaks down cyclic GMP.

By blocking PDE5, vardenafil helps cyclic GMP last longer, which makes it easier for blood vessels in the penis to relax and increase blood flow—but only when you are sexually stimulated.

What it is and what it is not for

• Helps with: achieving an erection and maintaining it during sexual activity
• Does not automatically cause erection: sexual stimulation is still required
• Does not treat: causes of ED such as diabetes, heart disease, or medication side effects—those should be addressed separately
• Does not protect against sexually transmitted infections (STIs): use condoms if needed

Pharmacokinetics (how the body handles vardenafil)

Pharmacokinetics describes how the medicine is absorbed, distributed, metabolised, and eliminated. Individual results vary.

• Absorption: Vardenafil is absorbed after oral dosing and reaches peak blood levels within a typical range of about 30–120 minutes (timing varies by formulation and person).
• Onset: Many people notice an effect within about 30–60 minutes, with some variability.
• Duration: The effect may last for several hours, although the exact “window” differs between individuals.
• Metabolism: Primarily metabolised in the liver (notably via the CYP3A4 pathway).
• Elimination: The drug is cleared from the body through metabolism and excretion.

If you do not feel an effect, it may be due to timing, dose, insufficient sexual stimulation, alcohol intake, certain drug interactions, or underlying health factors.

Typical use and timing

When to take it

• Take Levitra Professional before planned sexual activity.
• For many men, taking it about 30–60 minutes prior works well.
• If you are adjusting how you time it, consider waiting at least a few doses before concluding it “doesn’t work,” unless you experience side effects.

How often to take it

Follow the instructions provided with your product or those given by your healthcare professional. In general, PDE5 inhibitors are taken as needed rather than continuously. Do not exceed the recommended daily maximum.

Indications (what it is used for)

Levitra Professional (vardenafil) is indicated for the treatment of erectile dysfunction in adult men. It helps improve erection quality by enhancing blood flow during sexual stimulation.

Dosing guidance (common approach)

Dosing depends on your age, overall health, and how you respond to treatment. Strengths commonly used for vardenafil include 5 mg, 10 mg, and 20 mg.

General starting and adjustment concepts

• Some men start at a lower dose to assess tolerability.
• Others may begin at a standard dose if they have previously used PDE5 inhibitors effectively.
• Your clinician may adjust the dose based on effectiveness and side effects.

Important: Always follow the dosing instructions for your specific product and strength. If you have kidney or liver impairment or take interacting medicines, your appropriate dose may be different.

Missed doses

Levitra Professional is taken when needed for sexual activity. If you miss a planned dose, simply resume the next scheduled “as needed” timing for sexual activity.

Food interactions

Food—especially meals high in fat—can affect how quickly vardenafil works. A large, fatty meal may delay onset.

• For best timing: consider taking it with a lighter meal or on a relatively empty stomach.
• If you took it after a heavy meal: the onset may be slower; allow more time before deciding it’s not working.

Alcohol and vardenafil

Alcohol can reduce erectile function and sexual performance by affecting blood vessels and nervous system signals. Moderate alcohol may be tolerated by some men, but heavy drinking can significantly reduce effectiveness.

• Recommendation: Limit alcohol when using Levitra Professional.
• If you plan to drink: keep it moderate and allow time for digestion and effects.
• Stop and seek advice if you experience dizziness, fainting, chest pain, or severe side effects.

Medicine interactions (important safety information)

Vardenafil can interact with several medicines, especially those that affect blood pressure or liver enzymes. Some interactions can be serious. Always review your current medicines with a healthcare professional or pharmacist.

Absolute or high-risk interactions

• Nitrates (for example, glyceryl trinitrate/sublingual nitro, isosorbide dinitrate/mononitrate) and nitric oxide donors: Do not combine with PDE5 inhibitors due to risk of dangerous blood pressure lowering.
• Riociguat: Not to be taken with PDE5 inhibitors due to risk of low blood pressure.

Other notable interactions

• Alpha-blockers (used for prostate symptoms or blood pressure): may increase dizziness/low blood pressure risk. Dose timing and stabilisation may be needed.
• Strong CYP3A4 inhibitors (examples include some antifungals like ketoconazole/itraconazole and certain HIV protease inhibitors): can raise vardenafil levels and increase side effects. Dose adjustments or avoidance may be required.
• Some antibiotics and antivirals: can affect vardenafil metabolism—check with a pharmacist for your specific product.
• Antihypertensives (blood pressure medicines): the combination may contribute to blood pressure changes, particularly in people who are prone to dizziness.
• Other ED medications (PDE5 inhibitors): do not take vardenafil together with other PDE5 inhibitors.

Bring a list of your medicines (including over-the-counter products and herbal supplements) to any healthcare visit.

Safety profile and who should be extra careful

Most men tolerate vardenafil well, but side effects can occur. Your risk may be higher if you have heart problems, low blood pressure, severe liver or kidney disease, or take interacting medicines.

Common side effects

• Headache
• Flushing (warmth/redness)
• Indigestion or stomach discomfort
• Nasal congestion or runny nose
• Dizziness
• Temporary changes in vision (e.g., blurred vision, increased light sensitivity—less common)

Serious side effects – seek urgent help

• Chest pain, severe dizziness, or fainting
• Sudden vision loss or severe eye pain
• Sudden hearing loss or ringing in the ears
• Prolonged erection lasting more than a few hours (priapism)— this is an emergency

Situations requiring medical advice before use

You should discuss ED treatment options with a healthcare professional if you have any of the following:

• Significant heart disease, recent heart attack or stroke
• Low blood pressure or symptoms like fainting
• Severe liver or kidney impairment
• History of priapism or certain blood disorders (e.g., sickle cell anaemia)
• Conditions affecting erections (e.g., Peyronie’s disease)
• If you use nitrates or riociguat, vardenafil may be unsafe

Practical use tips for better results

• Try timing and food strategy: if the effect seems delayed, consider taking it earlier and avoiding heavy, fatty meals.
• Use with sexual stimulation: vardenafil enhances response to arousal, it does not replace it.
• Manage alcohol: keep intake moderate to preserve erection quality.
• Give it a few attempts: if the first try doesn’t work, it may be due to timing, stress, or meal/alcohol effects. Do not increase dose without advice.
• Plan for comfort: stress and performance anxiety can interfere with erections. A calm environment may help.
• Check interactions: especially nitrates, riociguat, and certain strong enzyme inhibitors.
• Don’t mix ED medicines: only one PDE5 inhibitor at a time.

Alternative options

If Levitra Professional is not suitable, not effective, or not tolerated, there are several alternatives. The “best” option depends on the cause of ED, your health, and preferences.

Other PDE5 inhibitors

• Sildenafil
• Tadalafil
• Other vardenafil formulations (where available)

Different PDE5 inhibitors may vary in onset, duration, and interaction profiles. Some men respond better to a specific agent.

Non-medicine approaches

• Address lifestyle factors: smoking cessation, weight management, regular exercise, and reducing alcohol.
• Psychosexual support for performance anxiety or relationship factors.
• Vacuum erection devices (medical devices).
• Penile injections or intra-urethral therapy (specialist-guided options).
• Evaluate underlying health: diabetes control, cardiovascular risk, and medication side effects.

FAQ

1) How quickly does Levitra Professional work?

Many men notice effects within about 30–60 minutes. Peak levels are often reached within 30–120 minutes. Heavy, fatty meals can delay onset.

2) How long does it last?

The effect can last for several hours in many people. The exact duration varies based on dose, food, alcohol, age, and individual response.

3) Do I need sexual stimulation?

Yes. Vardenafil helps the body’s response to arousal, but it does not automatically cause an erection without sexual stimulation.

4) Can I take it with food?

You can, but the timing may be slower after a heavy or fatty meal. For best results, consider taking it with a lighter meal or on a relatively empty stomach.

5) Is it safe with alcohol?

Alcohol can reduce erection quality and may increase dizziness in some men. Keep alcohol moderate and avoid heavy drinking. If you feel unwell, stop and seek advice.

6) What medicines should not be combined with vardenafil?

Do not use vardenafil with nitrates or riociguat. Many other medicines (including some for blood pressure, certain antibiotics/antifungals, and HIV medicines) can interact—ask a pharmacist if unsure.

7) What should I do if it doesn’t work?

Common reasons include:

• Timing issues (too soon or too late)
• Heavy meals
• Alcohol and stress
• Wrong dose or tolerance
• Drug interactions

If it repeatedly doesn’t work, discuss options and potential causes with a healthcare professional rather than increasing the dose on your own.

8) What side effects are common?

Common side effects include headache, flushing, nasal congestion, indigestion, and dizziness. These are usually mild and temporary.

9) When is a medical emergency?

Seek urgent medical help for chest pain, fainting, sudden vision or hearing problems, or an erection lasting too long (priapism).

10) Can I take it every day?

Most people use PDE5 inhibitors as needed. Daily use may be considered for some treatments in specific circumstances, but follow the dosing instructions provided for your product and your healthcare advice.

Summary

Levitra Professional (vardenafil) is a PDE5 inhibitor used for erectile dysfunction. It helps improve erections by enhancing blood flow in response to sexual stimulation.
