Vilitra (Vardenafil) – Patient Information (UK)

Vilitra is a medicine containing vardenafil, used to treat erectile dysfunction (ED) in adult men. It helps you achieve and maintain an erection when you are sexually aroused. This patient-friendly guide explains how Vilitra works, how to take it safely, what to expect, and important safety considerations for use in the United Kingdom.

Note: This information is for education only and does not replace advice from a healthcare professional.

Quick overview

• Active ingredient: Vardenafil
• Medicinal type: PDE5 inhibitor (phosphodiesterase type 5 inhibitor)
• Used for: Erectile dysfunction (ED) in adult men
• How it works: Improves blood flow to the penis during sexual stimulation
• Typical onset: Often within 30–60 minutes
• Duration: Effects commonly last several hours (individual response varies)

Basic product information

Vilitra is a brand of vardenafil. Depending on the product presentation, you may see different tablet strengths. Common strengths for vardenafil medicines include 5 mg, 10 mg, and 20 mg.

Vilitra is taken by mouth and should only be used for its intended purpose (ED). It does not protect against sexually transmitted infections.

Mechanism of action (how Vilitra works)

Vardenafil belongs to the PDE5 inhibitor group. During sexual arousal, nitric oxide is released in the body, which activates an enzyme pathway that increases levels of cGMP in penile tissue. cGMP helps relax smooth muscle in penile blood vessels, increasing blood flow to the penis.

PDE5 breaks down cGMP. By inhibiting PDE5, vardenafil helps maintain higher cGMP levels, supporting improved blood flow and helping you achieve an erection when you are sexually stimulated.

• Works with sexual arousal: Vilitra does not cause an erection automatically.
• Targets blood flow: It improves the ability to get and keep an erection by enhancing vascular response.

Pharmacokinetics (how the body handles Vilitra)

Pharmacokinetics describes how a drug is absorbed, distributed, metabolised, and eliminated. While individual responses vary, the following points are typical for vardenafil-containing products:

Absorption

• After oral dosing, vardenafil is absorbed from the gut into the bloodstream.
• Time to effect is generally within 30–60 minutes.
• Absorption can be slower if taken with a heavy meal (see Food interactions below).

Distribution

• Vardenafil distributes into body tissues and is largely protein-bound.

Metabolism

• Vardenafil is metabolised mainly in the liver by enzymes including CYP3A4.
• This matters because some medicines can increase or decrease vardenafil levels.

Elimination

• Vardenafil and its metabolites are eliminated mainly via the kidneys and bile.

Practical takeaway: Because vardenafil is processed in the liver and interacts with other drugs, it’s important to consider medicine interactions (especially nitrates and some heart medicines).

Indications (what Vilitra is used for)

Vilitra (vardenafil) is indicated for the treatment of erectile dysfunction in adult men.

• ED: Difficulty getting or maintaining an erection sufficient for satisfactory sexual activity.

Typical use and expectations

Vilitra is intended for on-demand use. Most men will start to notice effects within about an hour, though this can vary depending on your individual response, meal timing, and other medicines.

Important: Vilitra helps with erections only when you are sexually stimulated. It is not an aphrodisiac.

• For best results, take it when you plan to engage in sexual activity.
• If it doesn’t work the first time, it may still work later after adjustments to timing or dose (as advised by your clinician).

How and when to take Vilitra (timing)

Common guidance for on-demand PDE5 inhibitor use is to take Vilitra before sexual activity. Timing affects how quickly it begins to work.

Typical timing

• Plan ahead: Many people take vardenafil about 30–60 minutes before sex.
• Individual response varies: Some may need closer to 1–2 hours for optimal effect.

Consistency within your plan

• Try to keep timing and circumstances fairly consistent when assessing effectiveness.
• Consider adjusting timing if you took it far too close to a heavy meal or after alcohol (see below).

Dosing (general information)

Dosing should follow the instructions provided with your specific product and the advice from healthcare professionals. The exact starting dose and adjustments depend on your health status and other medicines.

General pattern for ED medicines in this class is that treatment often starts at a lower dose and may be adjusted based on response and tolerability.

• Common starting doses for vardenafil products in ED may be 10 mg or 5 mg depending on individual factors and product guidance.
• Typical effective dosing may range 5 mg to 20 mg in many situations, but maximum frequency limits apply.

Do not exceed the prescribed frequency (often once per day for on-demand use). If you miss a dose, do not take a double dose.

Special populations may need caution:

• Older adults: may be started conservatively.
• Hepatic impairment (liver problems): dose adjustments and extra caution may be required.
• Renal impairment (kidney problems): may influence tolerance and dose selection.

Food interactions (what you should know about meals)

Food—particularly fatty meals—can affect how quickly vardenafil is absorbed.

• Heavy or high-fat meals may delay onset of action.
• If your tablet seems less effective or takes longer than expected, consider taking it with a lighter meal or adjusting the timing.

Practical tip: Avoid very heavy meals right before taking Vilitra if you want a faster onset.

Alcohol interactions

Alcohol can affect erectile function by reducing arousal and causing blood vessel dilation, which may worsen the performance of ED treatments.

• Moderate alcohol: may reduce effectiveness in some men.
• Heavy alcohol intake: may increase side effects such as dizziness or headache and reduce ability to maintain an erection.

Safety note: Avoid excessive alcohol. If you feel dizzy or light-headed, do not drive and seek medical advice.

Medicine interactions (especially important)

Some combinations can be dangerous due to blood pressure effects or drug metabolism. Always review your current medicines with a clinician or pharmacist.

Absolute contraindication: nitrates

Do not take vardenafil with nitrates (for example, glyceryl trinitrate used for angina) or nitric oxide donors. The combination can lead to a dangerous fall in blood pressure.

Riociguat

Do not take vardenafil with riociguat (used for certain lung and blood pressure conditions). This can also cause severe hypotension.

Alpha-blockers

If you take an alpha-blocker (for urinary symptoms or blood pressure), combining with vardenafil can lower blood pressure further. Dose adjustments and careful timing may be needed.

• Examples include tamsulosin and other alpha-blockers (varies by country and product).

Strong CYP3A4 inhibitors (significant interactions)

Some drugs can raise vardenafil levels by affecting metabolism, increasing the risk of side effects.

• Examples may include certain antifungals and some antibiotics (e.g., ketoconazole/itraconazole; clarithromycin and similar medicines).
• Grapefruit and grapefruit juice can also influence drug levels.

Other PDE5 inhibitors

Do not combine Vilitra with other ED treatments such as other PDE5 inhibitors (e.g., sildenafil or tadalafil). Combining can increase side effects and does not usually improve safety or effectiveness.

Blood pressure medicines

Vilitra can lower blood pressure modestly. If you take antihypertensive medicines, your healthcare provider may need to monitor tolerance and adjust dosing.

“Recreational” nitrates or stimulants

• Do not use “poppers” (amyl nitrite or similar) or other nitrates with vardenafil.
• Be cautious with recreational drugs that affect blood pressure or blood vessels.

Safety profile (side effects and when to seek help)

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

Common side effects

• Headache
• Flushing (warmth/redness)
• Dizziness
• Indigestion or stomach discomfort
• Nasal congestion or runny nose

Less common but important effects

• Vision changes (rare)
• Changes in hearing (rare)
• Persistent erection (priapism) (rare but an emergency)
• Chest pain or severe dizziness

Seek urgent medical help immediately if

• An erection lasts 4 hours or more (possible priapism)
• You experience sudden vision loss or severe visual disturbances
• Severe dizziness, fainting, or symptoms of a heart problem occur
• Hives, swelling, or trouble breathing suggest an allergic reaction

Who should use Vilitra with extra caution?

• Men with significant heart disease or unstable angina
• Those with a history of stroke or serious cardiovascular events
• People with low blood pressure or risk of fainting
• Men with certain eye conditions (e.g., non-arteritic anterior ischaemic optic neuropathy history)
• Men with severe liver impairment or specific kidney issues

Practical use tips for better results

• Use when you plan sex: Take it at the right time rather than “just in case.”
• Eat smart: A heavy, especially fatty meal can delay onset. Consider lighter meals.
• Stay within safety limits for alcohol: Excess alcohol can reduce performance and increase side effects.
• Give it an honest trial: Some men need to find the right timing or dose with professional guidance.
• Maintain sexual arousal: The medicine supports the process, but arousal is still required.
• Don’t “double up”: If one dose doesn’t work, don’t take more than recommended in a short period.

Lifestyle note: ED is often linked with cardiovascular health, stress, smoking, and metabolic conditions. Healthy habits can improve both ED and overall wellbeing.

Alternative options

Depending on your medical history and preferences, alternatives to Vilitra may include:

Other PDE5 inhibitors

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

Different medicines can vary in onset, duration, and tolerability. Some people find a particular option fits their lifestyle better.

Non-drug options

• Vacuum erection devices
• Penile injections or intraurethral therapy (specialist-led)
• Psychosexual counselling for performance anxiety or relationship factors
• Managing contributing conditions such as diabetes, high blood pressure, and high cholesterol

Important: If you have ED, consider discussing underlying causes—especially if ED is new or worsening.
