Fildena Extra Power (Sildenafil Citrate) — Patient-Friendly Information (United Kingdom)

Fildena Extra Power is a brand of sildenafil citrate, a medicine used to help treat erectile dysfunction (ED) in men. This page explains how it works, how to use it safely and effectively, what to expect, and important UK-specific considerations. Always read the patient information leaflet included with your medicine and follow the advice of a qualified healthcare professional.

Important: Sildenafil is designed to help erections when you are sexually stimulated. It is not an aphrodisiac and does not protect against sexually transmitted infections.

At a Glance

• Active ingredient: Sildenafil citrate
• What it helps with: Erectile dysfunction (difficulty getting or maintaining an erection suitable for sex)
• How it works: Improves blood flow to the penis during sexual stimulation
• When to take: Typically 30–60 minutes before sexual activity
• Typical duration: Often up to around 4 hours (effects vary)
• Not for everyone: Avoid if you use nitrates or certain riociguat therapies

Basic Product Information

Mechanism of Action (How Sildenafil Works)

Sildenafil belongs to a group of medicines called PDE5 inhibitors. When you become sexually aroused, your body releases nitric oxide in the erectile tissue. This triggers a chain of events that increases levels of cyclic GMP (cGMP), helping smooth muscle relax and blood flow into the penis to support an erection.

PDE5 is an enzyme that breaks down cGMP. Sildenafil helps by inhibiting PDE5, which means cGMP lasts longer. As a result, blood flow to the penis improves only when sexual stimulation is present.

Pharmacokinetics (Absorption, Metabolism, and Elimination)

Pharmacokinetics describes how the body absorbs, processes, and removes a medicine. While individual responses vary, the following general points are commonly observed with sildenafil:

• Absorption: Sildenafil is absorbed after oral dosing. Peak effects typically occur within about 30–120 minutes.
• Food effects: A heavy or fatty meal can slow absorption and delay onset.
• Distribution: It circulates in the bloodstream and distributes into body tissues.
• Metabolism: Mainly metabolised in the liver by CYP450 enzymes (notably CYP3A4).
• Elimination: Metabolites are excreted primarily via the gut (faeces) and to a lesser extent via urine.
• Half-life (general): The body clears sildenafil over several hours; effects can last longer than the peak period.

Typical Use and Indications

Fildena Extra Power is indicated for the treatment of erectile dysfunction (ED)—the inability to achieve or maintain an erection adequate for satisfactory sexual activity.

It may be used in men with ED related to a variety of causes, such as vascular, psychological, or mixed factors. However, ED can be an early sign of underlying health issues (for example, cardiovascular disease), so it is wise to discuss concerns with a clinician.

How to Take Fildena Extra Power (Timing and Use)

For best results, sildenafil should be taken before sexual activity. It works more reliably when you allow enough time for absorption and you are sexually stimulated.

Timing

• Typical start time: Approximately 30–60 minutes before sex.
• Possible earlier/later onset: Some people notice effects sooner or later depending on digestion, stress, and overall health.
• Duration of effect: Often up to around 4 hours (some effects may extend beyond this; individual variation is common).
• Do not take too frequently: Follow dosing instructions on the product and avoid exceeding the maximum recommended frequency.

Practical Step-by-Step Tips

1. Plan ahead: Choose a time that gives you a window of at least 30–60 minutes.
2. Aim for calm arousal: Sildenafil supports erections during stimulation—it doesn’t automatically create an erection.
3. Consider comfort factors: Avoid heavy meals beforehand and stay well hydrated.
4. Review medication list: Check interactions (especially nitrates and some heart medicines).
5. Assess response safely: If one attempt doesn’t work, do not simply increase dose without medical advice.

Dosing (General Guidance)

Dosing may vary depending on your specific situation and the tablet strength available. In the UK, sildenafil for ED is commonly used at different strengths based on tolerability and response.

As a patient-friendly guide, the following principles are useful:

• Start low if appropriate: Many people begin with a lower strength to assess side effects.
• Do not exceed the maximum recommended frequency: Sildenafil is typically taken once within a 24-hour period for ED.
• Adjust if you have risks: Liver impairment, kidney impairment, age, and interacting medicines can require dose adjustment.
• Use the lowest effective dose: If you achieve satisfactory results, there is usually no need to increase.

Important: If you are unsure which tablet strength to use, or you have kidney/liver issues, heart conditions, or you take other medicines, consult a healthcare professional or pharmacist to ensure the safest dosing approach.

Food Interactions (What to Eat and Avoid)

Food can influence how quickly sildenafil is absorbed. A key point is that fatty meals may delay onset.

General food guidance

• Light meals: Usually less likely to delay effects.
• Heavy or high-fat meals: May slow absorption and make it harder to time the effect.
• Alcohol-related eating: If alcohol is involved, eating patterns can further affect timing and side effects.

If you want more predictable results, consider taking the tablet on a relatively lighter stomach or allowing extra time after a heavy meal.

Alcohol and Medicine Interactions

Alcohol

Moderate alcohol may not be a major issue for everyone, but alcohol can: reduce sexual performance, increase the risk of dizziness or low blood pressure, and worsen side effects such as headache or flushing.

• Higher alcohol intake: More likely to interfere with erections and increase adverse effects.
• Practical tip: If you use sildenafil, consider limiting alcohol and avoid binge drinking.

Key medicine interactions (very important)

Some medicines should not be combined with sildenafil due to potentially dangerous drops in blood pressure or serious cardiovascular effects.

Avoid sildenafil if you take any of the following:

• Nitrates (e.g., glyceryl trinitrate tablets/spray, isosorbide dinitrate/mononitrate) used for chest pain/angina
• Riociguat (used for pulmonary arterial hypertension)

Extra caution with the following (discuss with a clinician/pharmacist):

• Alpha-blockers (for prostate symptoms or high blood pressure, such as tamsulosin, doxazosin): may increase the risk of low blood pressure.
• Some antifungal medicines (e.g., ketoconazole, itraconazole) and antibiotics (e.g., clarithromycin): can increase sildenafil levels.
• HIV medicines (certain protease inhibitors): may increase sildenafil exposure.
• Other PDE5 inhibitors (do not combine).
• “Lifestyle” nitrates (including certain “poppers”): these can contain nitrates and may be extremely dangerous with sildenafil.

If you are taking several medicines, it is safest to review them with a pharmacist before using sildenafil for ED. For your safety, keep an up-to-date list of all medicines, including OTC products and herbal supplements.

Safety Profile and Side Effects

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

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Indigestion or stomach discomfort
• Nasal congestion (blocked nose)
• Visual disturbances (e.g., mild blurring or changes in colour perception)
• Dizziness

Serious side effects (seek urgent medical advice)

Contact urgent medical help if you experience:

• Chest pain or symptoms suggesting a heart problem
• Fainting or severe dizziness
• Sudden vision loss or significant visual changes
• Sudden hearing loss (rare)
• Prolonged erection (priapism) lasting 4 hours or more (this is an emergency—seek immediate medical attention)
• Severe allergic reaction (swelling of face/lips, breathing difficulty, severe rash)

Who should be extra cautious?

• People with a history of low blood pressure or significant cardiovascular disease
• Those with severe liver impairment or severe kidney impairment
• People taking multiple medicines that affect blood pressure or sildenafil metabolism
• Those advised to avoid sexual activity due to heart conditions

Practical Use Tips for Better Results

• Use sexual stimulation: Sildenafil supports erections only during arousal.
• Don’t rush dosing: Give it time to work; avoid taking too close to sex if you want maximum predictability.
• Choose timing around meals: If you have a heavy meal, allow extra time.
• Manage stress: Anxiety and performance pressure can reduce effectiveness.
• Consider overall health: Smoking, excess alcohol, lack of exercise, and uncontrolled diabetes or blood pressure can worsen ED.
• Monitor your response: If side effects occur, talk to a pharmacist about dose adjustments or alternatives.
• Consistency matters: ED is often influenced by health and routine—some improvement may take more than one try.

Alternative Options

Sildenafil is one PDE5 inhibitor option. Depending on your needs, other treatments may be appropriate. Alternatives include:

Other PDE5 inhibitors

• Tadalafil (often longer-lasting; may be taken at different regimens depending on suitability)
• Vardenafil
• Avanafil

Non-medicine approaches

• Lifestyle changes: exercise, weight management, reducing alcohol, stopping smoking
• Address contributing factors: diabetes control, blood pressure management, sleep and stress
• Psychosexual support: if anxiety or relationship factors are involved
• Mechanical options: vacuum erection devices (where suitable)
• Other medical options: injection therapies or hormone evaluation if indicated

A clinician can help match the most suitable option to your medical history and preferences, especially if you have complex health needs.

FAQ

How long does Fildena Extra Power take to work?

Many people notice effects within 30–60 minutes. A heavy or fatty meal can delay the onset, so timing may vary.

How long do the effects last?

Effects often last for up to around 4 hours, although individual responses vary. You may still be able to achieve erection with sexual stimulation during this window.

Can I take it every day?

For ED, sildenafil is generally used no more than once within 24 hours. Do not exceed the maximum recommended frequency stated on your product information.

What if it doesn’t work the first time?

ED can be influenced by stress, alcohol, meal timing, underlying health, and medication interactions. If you don’t get the expected effect, avoid increasing the dose on your own—speak with a pharmacist or clinician to review dosing and possible interactions.

Is sildenafil safe with blood pressure medicines?

It can be, but some blood pressure medicines (and other drugs) may increase the chance of low blood pressure. Alpha-blockers and certain heart medicines require particular caution. Check interactions and seek advice if unsure.

Can I drink alcohol when using sildenafil?

Alcohol may reduce sexual performance and increase side effects such as dizziness or headache. If you choose to drink, keep it moderate and avoid binge drinking.

What should I do if I get side effects?

Mild side effects like headache or flushing usually improve with time. If side effects are severe, persistent, or you experience chest pain, fainting, or vision/hearing changes, seek urgent medical advice.

Can I take sildenafil with nitrates?

No. Sildenafil should not be used with nitrates (including certain medicines and recreational “poppers”) because it can cause a dangerous drop in blood pressure.

Does sildenafil treat the cause of erectile dysfunction?

Sildenafil helps symptoms (erection performance) during sexual stimulation. It does not directly treat the underlying cause. If ED is persistent, consider discussing it with a healthcare professional—especially if you have diabetes, heart disease risk factors, or new/worsening symptoms.

Is Fildena Extra Power suitable for everyone?

Not necessarily. People with certain medical conditions or those taking specific medicines may need to avoid sildenafil or use a different approach. If you have heart problems, low blood pressure, severe liver/kidney impairment, or take interacting medications, seek advice before use.

How should I store the tablets?

Keep them in their original packaging, at room temperature, away from moisture and heat. Store safely out of reach of children.

Summary

Fildena Extra Power (sildenafil citrate) is an oral PDE5 inhibitor used for erectile dysfunction. It helps improve blood flow to support erections during sexual stimulation. For best results, take it with appropriate timing (often 30–60 minutes before sex), avoid heavy/fatty meals close to dosing, and be cautious with alcohol. Most importantly, never combine sildenafil with nitrates or riociguat due to safety risks.
