Fildena Super Active (Sildenafil Citrate) – Patient Information (UK)

Fildena Super Active contains sildenafil citrate, a medicine used for erectile dysfunction (ED). It helps many men achieve and maintain an erection when sexually stimulated. This guide explains how it works, how to take it safely, what to expect, and important interactions and precautions, tailored for customers in the United Kingdom.

Important: This information is for general patient guidance and does not replace advice from a healthcare professional.

Basic product information

What is erectile dysfunction (ED)?

ED is the difficulty getting or maintaining an erection firm enough for satisfactory sexual activity. It may be influenced by stress, relationship factors, lifestyle, or underlying medical conditions such as diabetes, cardiovascular disease, high blood pressure, or hormonal changes.

Sildenafil helps improve blood flow to the penis during sexual stimulation, making erections easier to achieve.

How Fildena Super Active works (mechanism of action)

Sildenafil belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors. During sexual stimulation, nitric oxide is released in the body, which increases cGMP (cyclic guanosine monophosphate). cGMP relaxes blood vessel walls, allowing increased blood flow to the penis.

• PDE5 normally breaks down cGMP.
• Sildenafil inhibits PDE5, helping cGMP levels remain higher for longer.
• The result is improved blood flow and an easier erection when sexually aroused.

Key point: Sildenafil does not automatically cause an erection. It works best when sexual stimulation occurs.

Indications: when it’s used

Fildena Super Active is used to treat erectile dysfunction in adult men.

It is intended for sexual activity in men who can safely use PDE5 inhibitors (for example, not taking medicines that interact dangerously with sildenafil).

Pharmacokinetics (absorption, distribution, metabolism, elimination)

Understanding how sildenafil behaves in the body can help you use it more effectively.

• Absorption: Sildenafil is absorbed from the gut after oral dosing. Peak blood levels typically occur around 30–120 minutes after taking a tablet.
• Onset of action: Many people notice effects within about 30–60 minutes, but this can vary.
• Food effects: A heavy or high-fat meal may delay absorption and reduce how quickly it starts working (more below).
• Distribution: Sildenafil distributes throughout the body and is partly bound to plasma proteins.
• Metabolism: Mainly processed in the liver by enzymes such as CYP3A4.
• Elimination: Metabolites are removed primarily via the faeces and to a lesser extent via the urine.
• Half-life: The effective half-life is typically around 3–4 hours, which is one reason many people experience effects for several hours.

Typical use and timing

For best results, plan the dose around sexual activity.

When to take it

• Take the tablet about 30–60 minutes before planned sexual activity.
• If you have eaten a large or heavy meal, consider allowing up to 2 hours for the medicine to work.
• Try to take it at a time when you can allow enough time for it to work before engaging in sexual stimulation.

How often

• Do not take more than prescribed on your product instructions or as advised by a healthcare professional.
• In general, sildenafil is commonly used only as needed rather than continuously.

If you don’t get the expected effect: Timing, food, alcohol, stress, smoking, and other medicines can affect how well sildenafil works. If problems persist, speak to a clinician to explore safe options and underlying causes.

Food interactions: what to avoid

Food can change how quickly sildenafil is absorbed.

• High-fat meals: May delay onset. Examples include very greasy, heavy, or large restaurant meals.
• Light meals: Usually less likely to delay effects.

Practical tip: If you want the medicine to act predictably, consider taking it on a relatively light stomach or ensuring you have time after a meal.

Alcohol interactions

Alcohol does not necessarily make sildenafil ineffective for everyone, but it can worsen erections by affecting blood vessels, arousal, and performance.

• Moderate alcohol: May reduce effectiveness for some men.
• Heavy drinking: Increases the likelihood of side effects such as dizziness and may make erections less reliable.
• Blood pressure effects: Sildenafil can lower blood pressure slightly; alcohol may add to this effect.

Safety approach: Keep alcohol intake moderate and avoid driving or operating machinery if you feel dizzy.

Medicine interactions (important safety information)

Sildenafil can interact with other medicines, sometimes in serious ways. Always review your current medicines carefully, including those bought online or from abroad.

Never combine with nitrates or “poppers”

The most critical interaction is with medicines that contain nitrates or substances that release nitric oxide.

• Nitrates used for chest pain (angina), such as glyceryl trinitrate (GTN), isosorbide dinitrate/mononitrate, etc.
• Recreational inhaled nitrates often referred to as poppers.

Reason: The combination can cause dangerous drops in blood pressure.

Alpha-blockers (prostate/urinary symptoms)

Men using alpha-blockers (for example, tamsulosin, doxazosin) for urinary symptoms or prostate enlargement may have increased risk of dizziness or low blood pressure, especially if starting sildenafil or changing doses.

• Healthcare advice may involve timing separation and starting at a lower dose.
• Seek medical guidance if you are on an alpha-blocker.

Other PDE5 inhibitors

• Do not combine sildenafil with other PDE5 inhibitors (such as tadalafil or vardenafil) because it increases side effects without improving safety.

Strong CYP3A4 inhibitors

Sildenafil is metabolised in the liver by CYP3A4. Medicines that strongly inhibit CYP3A4 can increase sildenafil levels, raising the risk of side effects.

• Examples may include some antifungals (e.g., ketoconazole/itraconazole) and certain antibiotics (e.g., clarithromycin) and some HIV treatments.

Ritonavir and cobicistat

These can substantially affect sildenafil metabolism. Combinations may require dose adjustments and close medical supervision.

Blood pressure medicines

Sildenafil may enhance the blood-pressure-lowering effects of some antihypertensive medicines. Most people tolerate this well when medically appropriate, but if you feel light-headed, stop sexual activity and seek guidance.

“Grey area” supplements and herbal products

Some “herbal” products marketed for ED may affect blood vessels or blood pressure. Because quality and ingredients can vary, it’s safest to avoid unverified combinations.

Dosing: how much to take

Dosing depends on the strength of the product and your response and tolerability. Follow the directions provided with your specific Fildena Super Active tablet pack.

General dosing principles (patient-friendly)

• Start with the lowest effective dose recommended for you.
• Take the tablet as needed prior to sexual activity.
• Do not exceed the maximum frequency stated on your product instructions.
• If you are elderly, have liver problems, or take interacting medicines, the starting dose may need to be lower.

If you miss a dose

This medicine is used as needed. If you were planning to take it and changed your mind, simply wait until the next planned occasion. Do not take extra doses to “catch up.”

What to expect: effectiveness and realism

Many men achieve improved erection quality. However, response varies.

• Sexual stimulation is required for sildenafil to work effectively.
• Time window: Many find it helpful to plan the dose 30–60 minutes before sex, adjusting for meals and personal response.
• Stress and performance anxiety: These can reduce effectiveness even when the medicine is taken correctly.

If your ED is related to an underlying condition (such as diabetes, vascular disease, or certain medication side effects), addressing the root cause can improve long-term outcomes.

Safety profile and potential side effects

Like all medicines, sildenafil can cause side effects. Most are mild to moderate and go away as the medicine wears off.

Common side effects

• Headache
• Flushing (warmth or redness)
• Indigestion or heartburn
• Nasal congestion
• Dizziness
• Visual changes (sometimes a bluish tinge or increased light sensitivity)

Less common but more serious side effects

• Chest pain or severe shortness of breath
• Fainting or severe dizziness
• Prolonged erection (see next section)
• Severe allergic reaction (swelling of face/lips, trouble breathing, rash)

Seek urgent medical help for the following

• Priapism: an erection lasting 4 hours or more. This is an emergency.
• Sudden vision loss or severe eye pain.
• Sudden hearing loss (rare, but reported).
• Symptoms of a dangerous blood pressure drop, such as collapsing, severe dizziness, or chest pain.

Practical use tips for better results

• Give it time: Allow 30–60 minutes before sexual activity (longer after a heavy meal).
• Keep alcohol moderate: Large amounts can reduce effectiveness and increase dizziness.
• Don’t rush: Take the tablet, stay relaxed, and allow your arousal to build naturally.
• Check interacting medicines: Especially nitrates, alpha-blockers, and strong inhibitors of liver enzymes.
• Hydrate and rest: Dehydration, poor sleep, and stress can contribute to ED.
• Know your conditions: If you have heart disease, low blood pressure, or uncontrolled high blood pressure, talk to a clinician before using ED medicines.

Who should be extra careful or avoid sildenafil?

Certain groups may need special caution or should not use sildenafil.

• Men taking nitrates or using poppers.
• People with severe heart conditions where sexual activity is not medically safe.
• Men with very low blood pressure or recent major cardiovascular events (your clinician can advise).
• People with certain eye conditions (for example, some forms of vision loss, retinal disorders) should seek medical advice.
• Those with a history of priapism or certain blood disorders affecting erections.
• Severe liver impairment or severe kidney impairment may require dose adjustment—seek advice.

If you are unsure whether sildenafil is safe for you, it’s best to consult a qualified healthcare professional.

Alternative options to consider (UK)
