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

Fildena Super Active contains sildenafil citrate, a medicine used to treat erectile dysfunction (ED) in men. This patient-friendly guide explains how it works, when to take it, what to expect, and important safety information for use in the United Kingdom.

Please read this information carefully. If you have questions about whether Fildena Super Active is suitable for you, speak to a pharmacist or healthcare professional.

Quick overview

• Active ingredient: Sildenafil citrate
• What it’s used for: Erectile dysfunction (difficulty achieving and/or maintaining an erection)
• How it works: Increases blood flow to the penis during sexual stimulation
• Typical onset: Often within 30–60 minutes
• Duration: Effects may last up to about 4 hours (timing varies by person)
• Key caution: Do not use with nitrates (for example, glyceryl trinitrate) or riociguat
• Alcohol: May reduce effectiveness and increase side effects

Basic product information

Fildena Super Active is an oral medicine containing sildenafil citrate. It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors.

In the UK, sildenafil is widely recognised for ED. Product strengths vary by manufacturer and presentation; always follow the strength instructions shown on the product packaging provided by your supplier.

What sildenafil does (in simple terms)

When you are sexually stimulated, sildenafil helps your blood vessels relax and improves blood flow to the penis. It does not automatically cause an erection without sexual stimulation.

How Fildena Super Active works (mechanism of action)

Sildenafil works by blocking an enzyme called PDE5. PDE5 normally breaks down cGMP, a chemical messenger involved in relaxing blood vessels.

• During sexual stimulation, the body releases nitric oxide.
• Nitric oxide increases cGMP.
• cGMP helps the smooth muscle in penile blood vessels relax.
• More blood flows into the penis, supporting erection quality.

By inhibiting PDE5, sildenafil helps maintain higher cGMP levels, improving the erectile response to sexual stimulation.

Pharmacokinetics (how the body processes it)

The following information describes typical behaviour in adults; individual experiences vary.

• Absorption: Sildenafil is absorbed after taking a tablet by mouth. Peak blood levels are typically reached in around 30 to 120 minutes.
• Onset of action: Many people notice effects within 30–60 minutes, depending on dose and whether food slows absorption.
• Duration: The effect usually lasts up to about 4 hours. Some men may still achieve erections later than that, but reliability may decrease.
• Metabolism: Mainly metabolised in the liver (primarily by CYP3A4).
• Elimination: Metabolites are eliminated mostly via faeces and urine.

For many users, practical timing is more important than exact pharmacology: take it in a planned way and allow sufficient time before sex.

Typical use and timing

When should you take it?

Fildena Super Active is taken as needed before sexual activity. You should aim to take it at a time that gives your body enough opportunity to start working.

• Typical timing: about 30–60 minutes before sex.
• Earlier timing may be needed: if you have taken it with very light food and want to see earlier effects.
• Later timing may occur: if you ate a heavy meal (especially fatty food).

How often can it be used?

Do not take more than once per day. The exact frequency may depend on the strength and your health status; follow the dosing guidance on the product or your clinician/pharmacist’s instructions if you have them.

Food interactions

Does food affect Fildena Super Active?

Yes. Food—particularly high-fat meals—can slow absorption and delay onset.

• Light meal: usually less effect on timing.
• Heavy/fatty meal: may delay when it starts working.
• Practical approach: If you want predictable timing, consider taking it with a lighter meal or on an emptier stomach.

Food does not generally remove sildenafil’s effect, but it may change when you feel it.

Alcohol interactions

What happens if you drink alcohol?

Alcohol can reduce sexual performance and can increase the chance of side effects such as dizziness, headache, flushing, and low blood pressure.

• Small amounts: may have limited impact for some people, but can still affect response.
• Moderate to heavy drinking: more likely to reduce effectiveness and worsen side effects.
• Safety tip: avoid excessive alcohol, especially if you are older or have cardiovascular risk factors.

If you feel light-headed or unwell after taking the medicine and drinking, stop alcohol and sit or lie down safely.

Medicine interactions (important)

Certain medicines can interact with sildenafil by changing its levels in the body or by increasing risks such as dangerously low blood pressure.

Do not combine with

Seek urgent medical advice if you have taken a nitrate-containing medicine recently and are considering sildenafil. The following are major contraindications:

• Nitrates (e.g., glyceryl trinitrate tablets/spray/patch; isosorbide dinitrate; isosorbide mononitrate)
• Riociguat

This combination can cause a significant drop in blood pressure.

Be cautious with medicines that affect sildenafil levels

Sildenafil is metabolised mainly by CYP3A4. Medicines that strongly affect this enzyme can increase sildenafil levels (raising side-effect risk) or reduce them (lowering effectiveness).

• Strong CYP3A4 inhibitors (may increase sildenafil exposure):
  • Some medicines for fungal infections (e.g., ketoconazole, itraconazole)
  • Some antibiotics (e.g., clarithromycin)
  • HIV protease inhibitors
• CYP3A4 inducers (may reduce sildenafil exposure):
  • Some treatments for seizures (e.g., carbamazepine, phenytoin, phenobarbital)
  • Rifampicin (an antibiotic)
  • St John’s wort (a herbal product)

Blood pressure medicines and alpha-blockers

• Antihypertensives and alpha-blockers (used for prostate symptoms and/or blood pressure) can also lower blood pressure.
• This may increase the chance of dizziness or faintness, particularly when starting or adjusting doses.

Other PDE5 inhibitors

Do not take sildenafil at the same time as other PDE5 inhibitors (such as tadalafil or vardenafil).

“Recreational” nitrites (“poppers”)

Avoid using nitrite inhalants (“poppers”) with sildenafil. This can cause a dangerous fall in blood pressure.

Indications: What Fildena Super Active is used for

Fildena Super Active (sildenafil citrate) is indicated for the treatment of erectile dysfunction in adult men—difficulty obtaining or maintaining an erection sufficient for satisfactory sexual performance.

It should not be used by women or children.

Dosing guidance (typical approach for adults)

Dosing depends on your overall health, age, other medicines, and how you respond. Always follow the dose printed on your product label or supplied by your pharmacy.

Typical adult dosing (general information)

• Starting dose: often begins at a lower strength to assess tolerance.
• Maximum: do not exceed one dose within 24 hours.
• Adjustments: may be needed for older age, liver impairment, kidney impairment, or drug interactions.

If you forget or miss a dose

Since Fildena Super Active is used as needed, you can simply take it when planning sexual activity according to timing guidance. Do not take extra doses to “catch up.”

When to seek advice about dose choice

Speak to a healthcare professional or pharmacist if you:

• are over 65
• have liver or kidney disease
• take multiple medicines, especially for blood pressure or heart conditions
• have a history of stroke or heart disease

What to expect (effectiveness and realism)

Sildenafil can improve erectile function, but results vary. It works best when:

• there is sexual stimulation
• you allow enough time before sex
• you avoid heavy, fatty meals right beforehand
• you limit alcohol

If an erection does not occur, do not automatically increase the dose immediately. Review timing, food/alcohol, stress, and other medications, and consider speaking with a pharmacist.

Safety profile: side effects and when to stop

Common side effects

Many side effects are mild and temporary. Commonly reported effects include:

• Headache
• Flushing (warmth/redness of skin)
• Indigestion or nausea
• Dizziness
• Blocked nose
• Visual changes (e.g., mild blurring or increased light sensitivity) in some men

Serious side effects – urgent medical attention

Stop using sildenafil and seek urgent help if you experience:

• Chest pain or signs of a heart problem
• Fainting or severe dizziness
• Sudden vision loss or sudden hearing changes
• Prolonged erection lasting 4 hours or more (priapism)
• Symptoms of severe allergic reaction such as swelling of face/lips, trouble breathing, or widespread rash

Who should be extra careful?

Check with a pharmacist or clinician if you have any of the following:

• severe cardiovascular disease or recent heart events
• very low blood pressure or uncontrolled high blood pressure
• history of stroke
• retinal disorders (including non-arteritic anterior ischaemic optic neuropathy)
• severe liver or kidney impairment
• conditions that predispose to priapism (e.g., sickle cell anaemia, leukaemia)

Sildenafil is not recommended for men who are medically advised not to engage in sexual activity due to cardiovascular risk.

Practical use tips for best results

• Plan timing: take it roughly 30–60 minutes before sex (adjust based on experience).
• Keep meals lighter: avoid heavy, fatty meals beforehand to reduce delays.
• Limit alcohol: moderation helps both performance and safety.
• Don’t “double up”: only take one dose per 24 hours.
• Give it an opportunity: if it works, it should help reliably over time; if it doesn’t, consider contacting a pharmacist.
• Manage stress: anxiety can interfere with erections, even when medication is working.
• Check interactions: review all current medicines, including over-the-counter and herbal products.

Alternative options for ED

If you find sildenafil doesn’t suit you, there are other evidence-based options. The best choice depends on your health, preferences, and interactions.

Other PDE5 inhibitors

• Tadalafil: often has a longer duration; may be suitable for those who prefer longer windows of effectiveness.
• Vardenafil and avanafil: alternative PDE5 inhibitors with different onset/duration profiles.

Other approaches

• Lifestyle changes: weight management, regular exercise, smoking cessation, and reducing alcohol can improve ED.
• Address underlying causes: diabetes, cardiovascular risk, stress, and certain medications can contribute.
• Consultation: if ED is persistent or new, medical review can identify treatable causes.

Never mix ED medicines without professional advice.

Fildena Super Active is a brand/product containing sildenafil citrate. Sildenafil is the active ingredient responsible for the ED effect.

2) How long before sex should I take it?

A common approach is 30–60 minutes beforehand. Heavy meals may delay onset. Many people find planning a light meal helps.

3) Will it work if I don’t get aroused?

No. Sildenafil helps improve blood flow in response to sexual stimulation. It is not an aphrodisiac.

4) Can I take it with food?

Yes, but avoid heavy, fatty meals as they can delay the effect. If you want more predictable timing, take it with a lighter meal or without a heavy meal.

5) Can I drink alcohol?

It’s best to limit alcohol. Alcohol can reduce effectiveness and increase side effects like dizziness and flushing.

6) What should I not combine it with?

Do not use sildenafil with nitrates or riociguat. Avoid “poppers” (nitrite inhalants) as well. Also be cautious with medications that affect liver enzymes or blood pressure.

7) What if I get side effects?

Many side effects are mild and temporary. If you feel unwell, stop sexual activity, sit or lie down, and seek medical advice if symptoms are severe or persistent.

8) How often can I take it?

Do not exceed one dose in 24 hours. If you need frequent use, discuss options with a pharmacist or clinician to ensure safety and suitability.

9) What if it doesn’t work?

Consider timing, whether you ate a heavy meal, alcohol intake, and whether you are taking interacting medicines. If ED persists, it may be useful to speak with a pharmacist or healthcare professional to explore causes and alternative treatments.

10) Is it safe for everyone?

Not necessarily. People with certain heart conditions, blood pressure issues, specific eye disorders, liver/kidney impairment, or those taking interacting medications may require extra caution.
