Levitra Professional (Vardenafil) — Patient Information (UK)

Levitra Professional contains vardenafil, a medicine used to treat erectile dysfunction (ED) in men. It works by improving blood flow to the penis when you are sexually stimulated.

This guide is designed to be patient-friendly and to help you understand how Levitra Professional works, how to use it safely, what to consider with food and alcohol, and when to seek medical advice.

Basic product information

Important: Always use the dose and instructions that match your personal treatment plan. If you are unsure which strength is suitable for you, check the information on your packaging or speak with a healthcare professional.

What is Levitra Professional used for?

Levitra Professional (vardenafil) is indicated for the treatment of erectile dysfunction—the difficulty getting or maintaining an erection firm enough for satisfactory sexual activity.

It does not increase sexual desire. It helps your body respond better to sexual stimulation by improving blood flow.

How it works (mechanism of action)

Vardenafil is a PDE5 inhibitor. PDE5 is an enzyme found in the smooth muscle of the blood vessels in the penis. During sexual arousal, nitric oxide is released, which activates a pathway that increases cyclic GMP. This leads to relaxation of smooth muscle and increased blood flow.

• Vardenafil blocks PDE5, allowing cyclic GMP to remain active for longer.
• This results in improved blood flow to the penis.
• The erection is achieved only when you are sexually stimulated.

Because it affects the blood vessels, vardenafil can also cause mild blood pressure lowering in some people.

Pharmacokinetics (how the body handles vardenafil)

Pharmacokinetics refers to how the body absorbs, distributes, metabolises, and eliminates a medicine.

• Absorption: Vardenafil is absorbed after oral dosing. Peak levels occur within a few hours.
• Onset: Many people feel effects within 30–60 minutes, though this varies.
• Duration: Effects may last several hours; for some men, the window of effectiveness can extend up to around 4–5 hours or sometimes longer, depending on dose, metabolism, and individual factors.
• Metabolism: Vardenafil is primarily metabolised by the liver (notably via CYP3A4 pathways).
• Elimination: The medicine and its metabolites are cleared mainly through the body’s normal elimination processes.

Practical implication: Because metabolism and absorption differ from person to person—and can be affected by certain medicines and liver function—your response and timing may vary.

Typical use in adults

Levitra Professional is usually used as needed before sexual activity. It is not a substitute for dealing with the causes of ED (such as diabetes, cardiovascular disease, anxiety, medication side effects, or lifestyle factors), and it does not protect against sexually transmitted infections.

When to take it:

• Take the tablet before planned sexual activity.
• Many people find it works best when taken around 30 minutes to 1 hour beforehand.
• Follow your specific dose instructions from your pack or treatment plan.

How often: The maximum frequency depends on the dose and your risk factors. Do not exceed the maximum daily dose stated for your strength and treatment plan.

Timing guidance (what to expect)

Timing can influence how well Levitra Professional works. Consider the following practical points:

• Usual onset: Effects often begin within 30–60 minutes.
• Best window: Commonly within the first couple of hours after taking the tablet.
• If your erection is not firm: Ensure there is adequate sexual stimulation; ED can be affected by overall health and anxiety. If repeated attempts are unsuccessful, speak to a clinician for review of dose and causes.
• Do not “stack doses”: Avoid taking extra doses close together if the first dose does not work.

Food interactions

Food—especially meals high in fat—can affect absorption and delay onset.

• High-fat meals: May slow down absorption and delay the time when you begin to feel effects.
• Timing with meals: If you notice reduced effect after heavy meals, consider taking it when you are not immediately after a large, fatty meal.
• Gentle approach: A lighter meal or taking it a bit earlier may help some people.

Tip: If you are trying it for the first time, consider testing on a day without a very heavy meal to better understand your personal response.

Alcohol interactions

Alcohol can worsen erectile function. While moderate alcohol may not directly “cancel” vardenafil, it can:

• reduce erection quality
• increase dizziness or headache (side effects that can be more noticeable with PDE5 inhibitors)
• raise risk of low blood pressure, especially if alcohol intake is high

Safety advice: Avoid heavy drinking when using Levitra Professional. If you feel light-headed, stop sexual activity and sit or lie down.

Medicine interactions (important)

Certain medicines can strongly affect how vardenafil works or increase the risk of side effects. Please review the following interaction groups. If you take any of these, seek medical advice before using vardenafil.

Do not use with nitrates

Vardenafil must not be used with nitrates (for chest pain/angina) or nitrite donors, because the combination can cause a significant drop in blood pressure.

• Nitroglycerin
• Isosorbide dinitrate/isosorbide mononitrate
• Some “poppers” (amyl nitrite, etc.)

If you have angina and need nitrates, speak to a healthcare professional about safe alternatives for ED treatment.

Use caution with “riociguat”

Vardenafil should not be used with riociguat (used for certain lung and blood pressure conditions), due to the risk of low blood pressure.

Strong CYP3A4 inhibitors

Medicines that strongly inhibit liver enzymes that break down vardenafil can raise vardenafil levels and increase side effects. Examples include:

• Some antifungals (e.g., ketoconazole, itraconazole)
• Some antibiotics (e.g., clarithromycin)
• HIV protease inhibitors (depending on regimen)

These combinations require careful dose adjustment or avoidance.

Alpha-blockers for prostate/urinary symptoms or blood pressure

If you take an alpha-blocker (for example tamsulosin, doxazosin, alfuzosin) for urinary symptoms or blood pressure, there may be increased risk of dizziness or low blood pressure when combined with vardenafil.

Healthcare advice may include starting with lower vardenafil doses and timing separation.

Other ED treatments

Avoid combining vardenafil with other PDE5 inhibitors (such as sildenafil or tadalafil) at the same time.

Blood pressure medicines

PDE5 inhibitors can enhance the blood-pressure-lowering effects of some antihypertensive medicines. Most people can still use them safely, but extra caution is needed if you’re prone to low blood pressure, dizzy on standing, or have certain heart conditions.

Risk of priapism (prolonged erection)

Caution is needed if you have conditions that predispose you to priapism, such as:

• Sickle cell anaemia or sickle cell traits
• Some blood disorders (e.g., leukaemia, multiple myeloma)
• Structural penile abnormalities

Also use caution if you take medicines that could affect blood clotting or red blood cell characteristics—ask for personalised advice.

Dosing: how to take Levitra Professional

Dosing can vary by individual circumstances such as age, liver/kidney function, and interacting medicines. The following is general information commonly used in practice; always follow your packaging or healthcare guidance.

Typical starting dose (general pattern)

• Common starting doses include 10 mg or 5 mg in some situations, depending on age and tolerance.
• Doses may be adjusted up or down based on response and side effects.

As-needed use

• Take a dose before sexual activity.
• Do not exceed the maximum recommended daily dose for your strength.
• If you try one dose and it does not work, sometimes adjusting the dose or timing (and addressing food interactions) can improve outcomes—but do not self-adjust repeatedly without advice.

Special situations where dose adjustments are often considered

• Older age
• Moderate to severe liver impairment
• Moderate to severe kidney impairment
• Concomitant medicines that increase vardenafil levels

If you forget to take it: Levitra Professional is usually taken only when needed. If you miss the planned time, take it only when it still fits your schedule for sexual activity—do not double up or take extra doses.

Safety profile and side effects

Like all medicines, vardenafil can cause side effects. Many are mild and temporary, but some require urgent attention.

Common side effects

• Headache
• Flushing (warmth or redness of the skin)
• Indigestion or stomach discomfort
• Nasal congestion or runny nose
• Dizziness
• Back pain or muscle aches (can occur with PDE5 inhibitors)

Less common but important side effects

• Vision changes (including blurred vision or increased light sensitivity)
• Palpitations or increased heart rate sensations
• Low blood pressure symptoms such as faintness or feeling very dizzy

Seek urgent medical help if

• Chest pain occurs during sexual activity
• You faint, or you have severe dizziness
• Priapism (an erection lasting longer than 4 hours) occurs
• Sudden vision loss or severe eye pain happens
• Signs of an allergic reaction appear (e.g., swelling of face/lips, rash with breathing difficulty)

Do not ignore symptoms: These can be emergencies, particularly because ED is sometimes associated with underlying cardiovascular risk.

Practical use tips (to get the best results)

• Plan ahead: Take it with enough time before sex, typically 30–60 minutes, unless your response suggests otherwise.
• Keep meals in mind: Avoid very heavy, fatty meals immediately before taking it.
• Use adequate stimulation: Vardenafil supports erections only with sexual arousal; it doesn’t automatically cause an erection.
• Start with a sensible dose: Use the dose assigned to you. If it doesn’t work, consider discussion of dose adjustment rather than repeated trial-and-error.
• Manage lifestyle contributors: Sleep, stress reduction, regular exercise, and limiting smoking/alcohol can improve ED.
• Check for underlying causes: Conditions such as diabetes, hypertension, cardiovascular disease, and depression can affect erections.

When Levitra Professional may not be suitable (contraindications and cautions)

You should not take vardenafil if you have been advised to avoid PDE5 inhibitors or if you have:

• Use of nitrates for angina or heart pain
• Use of riociguat
• Some serious heart conditions where sexual activity is not advised
• A history of non-arteritic anterior ischaemic optic neuropathy (NAION) (in some circumstances, PDE5 inhibitors may be avoided)

Extra caution is needed if you have:

• Significant liver disease
• Severe kidney disease
• Known bleeding disorders
• Conditions associated with priapism
• Very low blood pressure, or certain heart rhythm issues

If you are unsure: It’s best to seek medical advice to ensure the medicine is appropriate for your health conditions and other medications.

Alternative options to consider

If Levitra Professional isn’t suitable or doesn’t work well enough, there are several alternatives for ED. Options can include:

• Other PDE5 inhibitors: e.g., sildenafil or tadalafil (different onset and duration profiles).
• Different dosing strategies: some people may benefit from adjusting timing or using a different regimen under professional advice.
• Vacuum erection devices (mechanical solution)
• Psychosexual support if anxiety or performance stress is a major contributor
• Addressing underlying conditions: improving blood sugar control, reviewing medications that may cause ED, weight management, exercise, and smoking cessation
• Hormonal evaluation if low testosterone is suspected (only if clinically indicated)

Choice of alternative often depends on your health, other medicines, and preferences regarding timing and duration.

Market and legal context in the UK

In the UK, erectile dysfunction medicines containing PDE5 inhibitors are regulated, and availability may vary by formulation and route of supply. Different products may have different prescribing and supply arrangements depending on classification, strength, and local regulations at the time.
