Filitra Professional (Vardenafil) – Patient Information Guide (UK)

Filitra Professional is a medicine containing vardenafil, used to treat erectile dysfunction (ED). This patient-friendly guide explains how it works, how to take it, what to expect, key safety considerations, and practical tips for use. It also covers common interactions, UK availability, and frequently asked questions.

Important: This information is designed to help you understand the medicine. Always follow the instructions provided with your product and consult a healthcare professional if you have questions—especially if you have heart conditions, take other medicines, or have concerns about safety.

1) Basic product information

How it helps: Vardenafil belongs to a group of medicines called PDE5 inhibitors. It supports erections by improving blood flow to the penis when you are sexually stimulated.

2) What is vardenafil and how does it work?

Mechanism of action (simple explanation)

During sexual arousal, your body increases nitric oxide in penile tissue. This triggers a chemical pathway that relaxes smooth muscle in the penis and allows increased blood flow, helping you achieve and maintain an erection.

Vardenafil works by inhibiting PDE5 (phosphodiesterase type 5). PDE5 breaks down a key messenger involved in the erection process (cGMP). By blocking PDE5, vardenafil helps the erection pathway last longer, making it easier to achieve an erection in response to sexual stimulation.

• Not an aphrodisiac: You still need sexual stimulation for effect.
• Targets blood flow: It enhances the natural erectile mechanism.
• Improves erection quality: For many people, it helps erections become firmer and easier to maintain.

3) Pharmacokinetics (how the body handles it)

Absorption: Vardenafil is absorbed after taking a tablet by mouth. Peak levels typically occur within a few hours (often around 1–2 hours), though timing can vary between individuals.

Distribution: It distributes into tissues, including the sexual organs, and binds significantly to plasma proteins.

Metabolism: The liver primarily metabolises vardenafil, especially via the CYP enzyme system. This is one reason interactions with certain medicines can occur.

Elimination: Metabolites are cleared mainly through the liver and kidneys. The medicine’s effects usually wear off as drug levels fall.

Half-life (general idea): Vardenafil has a functional duration that can last for many hours, though the strongest effect is often within a narrower window after dosing.

4) Typical use and timing

When to take it

Filitra Professional is taken on demand, rather than as a daily medicine, for ED. The timing is important for best results.

Common guidance:

• Take it about 30 minutes to 1 hour before you expect to have sex.
• Some people may find it works best closer to 1 hour; others respond sooner. Start with a consistent routine to learn your timing.
• Effects may last long enough for intimacy within the same general timeframe.

How to know it’s working

• You should be able to achieve an erection that is firm enough for sexual activity.
• If you don’t respond, factors such as inadequate stimulation, too much alcohol, incorrect timing, or interactions with other medicines may be involved.

5) Indications (what it is used for)

Filitra Professional (vardenafil) is indicated for the treatment of erectile dysfunction—the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance.

It is intended for use by adults and is used when ED affects quality of life. It does not treat low libido directly, nor does it treat the causes of ED by itself. If ED is new or worsening, it can be a sign of cardiovascular or metabolic conditions, so medical review may be helpful.

6) Dosing (typical adult regimens)

Always follow the exact instructions provided with your product. Dose selection may differ based on age, other medicines, and medical conditions.

Common on-demand dosing

• Most adults: A starting dose is often 10 mg, taken as needed before sexual activity.
• Adjustments: If needed and tolerated, the dose may be increased to 20 mg or reduced to 5 mg depending on effectiveness and side effects.
• Frequency: Generally, no more than one dose per day is recommended.

Older adults and certain risk factors

• Some people may require a lower starting dose due to sensitivity or the presence of interacting medicines.
• People with certain liver or kidney impairments may need modified dosing and closer monitoring.

If you miss a dose

Because this medicine is taken on demand, you typically don’t take it on a schedule. Instead, take the next dose only when you plan sexual activity and according to the instructions provided.

7) Food interactions and what to eat

Food can affect absorption. A heavy or high-fat meal may delay or reduce the onset of action. If you take it with a large meal, you may need to plan earlier than usual.

Practical advice

• For best results, consider taking it on an emptier stomach or with a light meal.
• If you’ve eaten a heavy meal, consider allowing more time before sexual activity.

Grapefruit / grapefruit juice: Some PDE5 inhibitors are affected by compounds in grapefruit. To be cautious, avoid grapefruit products unless advised otherwise by a clinician.

8) Alcohol and medicine interactions

Alcohol

Alcohol can increase the risk of side effects such as headache, dizziness, flushing, and low blood pressure. It can also reduce sexual performance directly by affecting the nervous system and blood flow.

• Moderate alcohol may still be compatible for some people, but avoid heavy drinking.
• If you notice reduced effectiveness or more side effects after alcohol, reduce alcohol intake for future attempts.

Medicines you must not combine (important safety)

Vardenafil can dangerously interact with nitrates (used for chest pain/angina) and with certain nitric oxide–related medicines.

• Do not take vardenafil with nitrates (for example, glyceryl trinitrate/nitroglycerin, isosorbide dinitrate/mononitrate) or nitrate-containing preparations.
• Do not take vardenafil with “poppers” or recreational nitrite products.

Reason: The combination can cause a significant and potentially life-threatening drop in blood pressure.

Other interaction examples (discuss with a clinician/pharmacist)

Certain medicines can raise vardenafil levels or increase the risk of side effects.

• Strong CYP3A4 inhibitors (e.g., some antifungals such as ketoconazole; some HIV treatments such as ritonavir) may increase vardenafil exposure.
• Alpha-blockers (used for urinary symptoms/prostate enlargement) can also lower blood pressure. The combination may require careful dosing/timing.
• Other PDE5 inhibitors should not be taken together.
• Antihypertensive medicines may amplify blood-pressure lowering effects.

Herbal products: Be cautious with supplements marketed for sexual performance. Some may contain hidden drug ingredients or interact with PDE5 inhibitors.

9) Safety profile (side effects and warning signs)

Common side effects

Most people tolerate vardenafil well. However, side effects can occur. Common side effects include:

• Headache
• Flushing (warmth/redness of the face)
• Indigestion or nausea
• Dizziness
• Blocked nose (nasal congestion)

Less common but serious risks

Seek urgent medical help if you experience:

• Chest pain, severe dizziness, fainting, or symptoms suggesting a serious drop in blood pressure.
• Sudden vision changes or a serious eye condition.
• Sudden hearing changes (rare).
• Priapism: an erection lasting 4 hours or more without relief. This is an emergency.
• Severe allergic reaction: swelling of face/lips, difficulty breathing, or widespread rash.

Who needs extra caution

Discuss use with a healthcare professional before taking vardenafil if you have:

• Heart disease or a history of serious cardiovascular events
• Low blood pressure or fainting episodes
• Severe liver or kidney problems
• Retinitis pigmentosa (a rare inherited eye condition)
• Conditions associated with prolonged erections (e.g., certain blood disorders)

10) Practical use tips for best results

• Plan the timing: Allow enough time before sex (often 30–60 minutes).
• Use sexual stimulation: Vardenafil supports erections when arousal occurs.
• Keep expectations realistic: ED can involve psychological and physical factors; improvements may take a few attempts.
• Start at a suitable dose: If you’re starting, follow the recommended starting strength and adjust only if advised.
• Avoid heavy meals and excess alcohol: Both can reduce effectiveness and increase side effects.
• Check medicine interactions: Review all current medicines, including over-the-counter and herbal products.
• Don’t “double up”: Do not take extra doses to catch up—stick to the daily maximum.

If it doesn’t work after several appropriately timed attempts, do not simply keep increasing the dose on your own. Consider speaking with a clinician/pharmacist to review dose, timing, and interactions.

11) Alternative options (if Filitra Professional isn’t suitable)

ED has multiple treatment pathways. Depending on your health profile and preferences, alternatives may include:

Other PDE5 inhibitors

• Sildenafil
• Tadalafil
• Avanafil

Different PDE5 inhibitors vary in onset and duration. Some people respond better to one than another.

Non-PDE5 approaches

• Lifestyle changes: improving sleep, reducing smoking, physical activity, and weight management.
• Psychosexual support: anxiety and performance pressure can worsen ED.
• Vacuum erection devices
• Injections or intraurethral therapies (specialist-led)
• Hormone evaluation if low testosterone is suspected

Your best option depends on the cause of ED, cardiovascular health, and medication interactions.

12) United Kingdom market and legal context

In the UK, medicines for erectile dysfunction are generally regulated and dispensed under the National Health Service (NHS) and private healthcare routes. Availability and rules depend on the product type and formulation.

• Medicines regulation: Vardenafil-containing products must be authorised and meet UK regulatory standards to be legitimately supplied.
