Filitra (Vardenafil) – Patient Guide (UK)

Filitra contains vardenafil, a medicine used to treat erectile dysfunction (ED) in adult men. This guide explains how Filitra works, when and how to take it, what to expect, and important safety information. It is written for patients in the United Kingdom and focuses on practical, everyday use.

If you have specific questions about suitability for you—especially if you take other medicines or have heart conditions—speak with a qualified healthcare professional.

Quick Product Information

How Filitra Works (Mechanism of Action)

Vardenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. During sexual arousal, nitric oxide is released in the penis. This increases levels of cGMP, which helps relax smooth muscle and allows more blood into erectile tissue.

PDE5 is an enzyme that breaks down cGMP. By blocking PDE5, vardenafil helps:

• Support natural erectile response during sexual stimulation
• Improve blood flow to help achieve and maintain an erection
• Reduce the breakdown of cGMP, helping the erection last longer (for as long as sexual stimulation continues)

Important: Filitra does not create arousal by itself. Sexual stimulation is still required for it to work effectively.

Pharmacokinetics (How Your Body Processes It)

Understanding how long vardenafil takes to act can help with timing.

• Absorption: Vardenafil is absorbed after oral administration and reaches peak concentration in the bloodstream within about 1 hour (timing can vary among individuals).
• Onset: Many people begin to notice effects within 30–60 minutes. Some may need a longer period.
• Duration: Effects may last for several hours. A common “use window” is within 4–6 hours, though individual response varies.
• Metabolism: The liver metabolises vardenafil, mainly via CYP3A4.
• Elimination: Metabolites are mainly cleared by the liver and kidneys.

Because other medicines can change how quickly vardenafil is broken down, the timing and intensity of effects may differ if you take interacting drugs (see below).

What Filitra Is Used For (Indications)

Filitra is indicated for the treatment of erectile dysfunction (ED) in adult men. ED is the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance.

Vardenafil is not intended for use by women or children.

Typical Use and When to Take It (Timing)

Filitra is usually taken as needed before sexual activity.

Common timing guidance

• Take Filitra about 30–60 minutes before planned sex.
• If needed, some people may find it helpful to take it closer to 1 hour beforehand.
• Try not to take more than once in a 24-hour period unless advised otherwise by a healthcare professional.

Tip: Plan your first few uses so you can “test” your response. Factors such as meal size and alcohol can affect onset and strength of effect.

Dosing (How Much to Take)

Dosing should be individualised based on your health, other medicines, and response. Below is general information commonly used in adult ED treatment.

Typical starting dose (adults)

• 10 mg once daily taken as needed about 30–60 minutes before sex is a common starting regimen.
• Depending on response and tolerability, the dose may be adjusted to 5 mg or 20 mg.

Maximum frequency

• For most people, do not exceed once per day.

Special situations where dose may need adjustment

• Older age: dose may start lower depending on overall health and tolerability.
• Liver impairment: may require lower doses and caution.
• Kidney impairment: may require adjustments depending on severity.
• Concurrent medicines: some drugs raise vardenafil levels (leading to increased risk of side effects), which may require dose adjustments.

Do not change your dose without professional advice. If you’ve missed a planned dose, do not take extra to “catch up”—simply resume the usual schedule next time.

Food Interactions (Including “High-Fat Meals”)

Food can influence how quickly and how strongly vardenafil works.

• High-fat meals may delay absorption and slow onset, potentially making the effect less noticeable when taken as planned.
• If you eat a large, heavy meal shortly before dosing, it may be helpful to take Filitra with more time in advance or choose lighter meals on the day you plan to use it.

Smaller meals are often easier to tolerate and may reduce delays. However, individual differences are normal—your own experience is important.

Alcohol: Interaction and Practical Advice

Alcohol can affect erections in multiple ways. Moderate to heavy drinking may:

• Reduce sexual performance and arousal
• Worsen blood vessel response
• Increase the likelihood of dizziness or low blood pressure

How it can interact with vardenafil: Because vardenafil helps relax blood vessels, combining it with alcohol may increase the chance of side effects such as dizziness or light-headedness.

Practical tip: If you drink, keep it moderate. Avoid getting overly intoxicated—this is not only a safety concern but can also reduce effectiveness.

Medicine Interactions (Important Safety Warnings)

Some medicines can interact with vardenafil by changing its metabolism or by affecting blood pressure. Always tell a pharmacist or clinician about all medicines you take, including over-the-counter products and herbal remedies.

Absolute or near-absolute contraindications

• Nitrates (for chest pain/angina) and nitric oxide donors—for example, glyceryl trinitrate (GTN)—should not be combined with PDE5 inhibitors. This combination can cause a dangerous drop in blood pressure.
• Riociguat (for certain lung blood pressure conditions) should not be used with PDE5 inhibitors due to the risk of severe hypotension.

Other interactions that commonly require caution

• Alpha-blockers (used for prostate symptoms and sometimes blood pressure) can increase the risk of low blood pressure, dizziness, and fainting. If you take an alpha-blocker, careful timing and dose adjustments may be needed.
• Strong CYP3A4 inhibitors (medicines that slow vardenafil breakdown) can raise blood levels. Examples may include some antifungals and certain antibiotics. Increased levels can raise the risk of side effects.
• Moderate inhibitors may also affect levels, requiring caution.
• Inducers of metabolism may reduce effectiveness.

Blood pressure medicines

Vardenafil can lower blood pressure modestly. If you also take antihypertensive medicines, this could increase the chance of dizziness—especially at the start of treatment or if doses change.

Seek urgent medical help if you develop severe dizziness, fainting, chest pain, or symptoms suggesting a serious allergic reaction.

Safety Profile (Common and Serious Side Effects)

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

Common side effects

• Headache
• Flushing (warmth/redness of the skin)
• Indigestion or stomach discomfort
• Blocked or runny nose
• Dizziness
• Nausea
• Back pain (sometimes reported)

Serious but rare side effects

Stop using vardenafil and get medical help urgently if you experience:

• Chest pain or worsening heart symptoms
• Fainting or severe dizziness
• Prolonged erections (priapism) lasting more than 4 hours—this is an emergency
• Sudden vision changes or severe eye pain
• Sudden hearing changes or ringing in the ears
• Signs of a serious allergic reaction such as swelling of the face/lips, rash, or difficulty breathing

Driving and machinery: If you feel dizzy, do not drive or operate machinery.

Practical Tips for Getting the Best Results

• Give it a proper trial: The first attempt may not fully reflect your best response. Consider trying the correct dose on more than one occasion.
• Mind the meal: Avoid very heavy, high-fat meals before taking Filitra.
• Stay relaxed: Stress and anxiety can worsen ED. Using Filitra alongside reducing pressure can help.
• Ensure sufficient sexual stimulation: Vardenafil supports erections but does not replace arousal.
• Keep alcohol moderate: Excess alcohol can reduce effectiveness and increase dizziness.
• Don’t “double up”: Taking extra doses increases side effects risk without guaranteeing better results.
• Check your medicines list: Especially nitrates, alpha-blockers, and medicines that affect liver enzymes.
• Consider underlying health: ED can be linked to cardiovascular health, diabetes, smoking, and stress. If ED is new or worsening, it’s wise to have a medical review.

Who Should Use Extra Caution?

Tell a healthcare professional before using Filitra if any of the following apply:

• Heart disease, unstable angina, or recent heart attack or stroke
• Very low blood pressure or a history of fainting
• Significant liver impairment
• Severe kidney impairment
• Conditions associated with priapism (e.g., sickle cell anaemia, certain blood disorders)
• Eye conditions such as non-arteritic anterior ischaemic optic neuropathy (NAION)
• Use of medicines for high blood pressure or prostate symptoms (especially alpha-blockers)

Sex should be avoided if your doctor advises against sexual activity due to heart risk.

Alternative Options (Other Treatments for ED)

If Filitra isn’t suitable or doesn’t work well, other options may be considered. These include:

Other PDE5 inhibitors

• Sildenafil (another PDE5 inhibitor)
• Tadalafil (often longer acting for some people)
• Avanafil (another PDE5 inhibitor with different onset characteristics)

Switching within the same class may improve results if timing and side effects suit you better with another option.

Non-PDE5 approaches

• Vacuum erection devices
• Intra-cavernosal injections (specialist-administered options)
• Intra-urethral treatments (in some settings)
• Psychosexual support when performance anxiety or relationship factors contribute
• Lifestyle changes such as stopping smoking, managing diabetes, exercise, and reducing alcohol

Your best choice depends on health status, convenience, and how your body responds.
