Basic Product Information

How Fildena Professional Works (Mechanism of Action)

Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors.

When sexual stimulation occurs, nitric oxide is released in the erectile tissue of the penis. Nitric oxide activates an enzyme pathway that increases cyclic guanosine monophosphate (cGMP). cGMP helps relax smooth muscle in penile blood vessels, allowing increased blood flow and helping you achieve an erection.

PDE5 normally breaks down cGMP. Sildenafil blocks PDE5, which helps cGMP stay active longer. The result is improved erectile response to sexual stimulation.

Important: Sildenafil does not cause an erection automatically. It works only when you are sexually stimulated.

Pharmacokinetics (Absorption, Onset, and Duration)

Pharmacokinetics describe how your body absorbs, processes, and clears a medicine.

• Absorption: Sildenafil is absorbed after oral dosing. Peak blood levels are typically reached within about 1 hour, but this can vary by person.
• Onset of action: Many people notice effects within 30–60 minutes after taking the dose.
• Duration: Effects can last for several hours. A practical “window” is often around 4 hours, though individual responses vary.
• Metabolism: Sildenafil is primarily metabolised by the liver enzyme system (commonly involving CYP3A4).
• Elimination: The medicine and its metabolites are cleared mainly through the liver and bile and partly via kidneys.

If you are older, have liver problems, or take certain interacting medicines, onset and duration may differ. In these cases, clinicians may advise a lower starting dose.

What Fildena Professional Is Used For (Indications)

Fildena Professional is indicated for:

• Improving erectile function in men with erectile dysfunction (ED).

ED may be due to stress, performance anxiety, vascular health, hormonal factors, medication side effects, diabetes, cardiovascular risk factors, or a combination of causes. Sildenafil treats the symptom of ED—rather than fixing every underlying cause.

Typical Use and Timing

Sildenafil is usually taken before sexual activity. Because it works best when timing aligns with sexual stimulation, consider the following general approach:

• Take about 30–60 minutes before planned sexual activity.
• If you don’t have a heavy meal beforehand and you’re not taking foods that slow absorption, the onset may be earlier.
• If you are planning a larger or high-fat meal, you may need to allow more time (see the food section below).

How often? Follow the dosing plan provided by your clinician or the product directions. Avoid exceeding the recommended maximum dose in 24 hours.

Dosing (General Guidance)

Dosing varies based on age, medical conditions, kidney or liver function, and interactions with other medicines. For patient safety, the most appropriate dose is individual.

Common dosing principles for sildenafil in ED include:

• Many users start with a dose such as 50 mg (depending on product strength and clinical advice).
• Some people may require adjustment higher or lower based on effectiveness and side effects.
• Older age or significant liver impairment may require a lower starting dose.
• Drug interactions (especially with medicines that affect sildenafil metabolism) may require dose reduction and additional safety monitoring.

Do not combine: Avoid taking more than one sildenafil product at the same time, and avoid “stacking” PDE5 inhibitors.

If you have any cardiovascular concerns, fainting episodes, chest pain, or have been advised to avoid sexual activity, seek medical advice before using sildenafil.

Food Interactions (Including High-Fat Meals)

Food can influence how quickly sildenafil works.

• High-fat meals may reduce the rate of absorption and delay onset.
• Faster onset is often seen when sildenafil is taken on a relatively lighter meal schedule.
• If you take sildenafil after a heavy, fatty meal, you may notice it works later than expected.

Practical suggestion: For best predictability, consider taking your dose with a light meal or ensuring your meal timing doesn’t fall immediately after a heavy, high-fat dinner.

Alcohol Interactions

Alcohol can worsen erectile function for some men because it may affect arousal, nerve signalling, and blood vessels. It can also increase the risk of side effects such as dizziness or low blood pressure.

• Moderate alcohol: Some people tolerate this, but results vary.
• Excess alcohol: More likely to impair erections and increase light-headedness.
• Hydration: Dehydration from alcohol may contribute to headaches and reduced performance.

Safety tip: If you feel dizzy, unsteady, or unusually flushed, avoid driving and avoid further alcohol. Stop sexual activity if you experience symptoms such as chest pain, severe dizziness, or shortness of breath.

Medicine Interactions (Important Safety Information)

Certain medicines can interact with sildenafil by increasing its level in the blood or by affecting blood pressure. This can increase the risk of side effects or serious complications.

Medicines to avoid (key interaction)

• Nitrates (used for angina/chest pain) and nitric oxide donors. The combination can cause a significant fall in blood pressure.
• Riociguat (for pulmonary arterial hypertension). This combination is also associated with dangerous blood pressure lowering.

If you take any medicine for chest pain, pulmonary hypertension, or “heart” conditions, confirm sildenafil compatibility with a qualified healthcare professional.

Medicines that may require caution or dose adjustment

• Alpha-blockers (for prostate symptoms or high blood pressure) can also lower blood pressure. A careful starting dose and spacing may be required.
• Strong CYP3A4 inhibitors (which can increase sildenafil concentration), such as some antifungal or antibiotic medicines, may raise side effect risk.
• Other blood pressure medicines can contribute to dizziness or hypotension.
• Some HIV medicines may affect sildenafil metabolism.

Non-prescription and herbal products

• Herbal products marketed for sexual performance or “blood flow” may have unpredictable interactions.
• If you use supplements, including those that may affect heart rate or blood pressure, inform a clinician or pharmacist.

Action step: Keep a list of all medicines and supplements you take and review them with your pharmacist or clinician before starting sildenafil.

Safety Profile and Common Side Effects

Most people tolerate sildenafil well when used correctly. However, side effects can occur.

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Indigestion or nausea
• Stuffy or runny nose
• Dizziness
• Visual changes (e.g., mild colour tinting or increased light sensitivity)

Less common but serious reactions (seek urgent medical help)

• Chest pain, severe shortness of breath, or fainting
• Sudden vision loss or sudden hearing changes
• Prolonged erection (priapism) lasting more than a few hours—this requires emergency care
• Severe dizziness or symptoms of very low blood pressure

Do not ignore warning signs. If severe symptoms occur, seek urgent help.

Practical Use Tips for Best Results

• Choose the right timing: Start with a dose taken about 30–60 minutes before sexual activity.
• Start with a consistent routine: Stress, sleep, and overall health influence ED. Sildenafil supports erectile response but cannot replace healthy habits.
• Keep meals in mind: If you eat a heavy or fatty meal, allow more time for onset.
• Avoid excessive alcohol: It can undermine erections and increase side effects.
• Relax and allow stimulation: Sildenafil helps erections occur in response to stimulation.
• Track what works: If one attempt is delayed due to meal timing, note when you took it and how it affected response for your next attempt.
• Consider underlying causes: ED can be related to cardiovascular health, diabetes, smoking, anxiety, and medications—address these with your healthcare provider.

Who Should Take Extra Caution?

Speak with a clinician before using sildenafil if you have:

• Heart disease or unstable angina
• Low blood pressure or episodes of fainting
• History of stroke or significant cardiovascular events
• Severe liver or kidney impairment
• Retinitis pigmentosa or inherited eye diseases
• Blood cell disorders such as sickle cell anaemia
• Pulmonary hypertension treated with interacting medications

Sexual activity itself is a physical stressor; if you have cardiovascular risk, your medical team may advise a safe approach.

Alternative Options for Erectile Dysfunction

If sildenafil doesn’t suit you, several alternatives may be considered depending on your situation and medical history.

Other PDE5 inhibitors

• Tadalafil (often longer-lasting)
• Vardenafil
• Avanafil

Non-PDE5 options

• Vacuum erection devices
• Penile injections (specialist-guided)
• Intraurethral therapy (where available)
• Psychological support for anxiety-related ED

Lifestyle and underlying health approaches

• Smoking cessation
• Regular exercise
• Managing diabetes, blood pressure, and cholesterol
• Reducing excess alcohol
• Sleep and stress management

A healthcare professional can help choose the most appropriate option based on effectiveness, tolerability, and interactions.

FAQ – Fildena Professional (Sildenafil Citrate)

1) How long before sex should I take Fildena Professional?

Most people take it about 30–60 minutes before sexual activity. If you’ve had a heavy/high-fat meal, allow more time as onset may be delayed.

2) How long does it work?

Effects may last for several hours (commonly up to about 4 hours), but the actual response varies by person and circumstances.

3) Will sildenafil automatically cause an erection?

No. Sildenafil helps the body respond to sexual stimulation. You still need arousal for an erection to occur.

4) Can I take it with food?

Yes, but heavy or fatty meals may delay onset. For more predictable timing, consider taking it with a lighter meal or allowing extra time after dinner.

5) Is it safe to drink alcohol?

Moderate alcohol may be tolerated by some people, but excessive alcohol can reduce effectiveness and increase dizziness or low blood pressure risk. Avoid heavy drinking and stop if you feel unwell.

6) What medicines should I not combine with sildenafil?

Do not use sildenafil with nitrates or riociguat. Use extra caution with alpha-blockers and medicines that strongly affect sildenafil metabolism (such as certain antifungals/antibiotics).

7) What if I have side effects?

Common side effects include headache, flushing, and dizziness. If side effects are bothersome, seek advice. Seek urgent help for severe symptoms such as chest pain, fainting, sudden vision/hearing changes, or an erection lasting too long.

8) What should I do if it doesn’t work?

Consider factors such as timing, meal size, alcohol intake, adequate sexual stimulation, and underlying health. If it’s consistently ineffective, consult a clinician to review dose, interactions, and potential causes of ED.

9) Can I use it every day?

Usage frequency should follow your healthcare advice. Many ED treatment plans use sildenafil on-demand before sexual activity. Daily use is not appropriate for everyone and must consider safety and interactions.

10) Are there alternatives if sildenafil isn’t suitable?

Yes. Other PDE5 inhibitors or non-PDE5 options may be appropriate. Your clinician can advise based on your health profile and medication list.

Summary

Fildena Professional (sildenafil citrate) is a PDE5 inhibitor used to treat erectile dysfunction. It improves erectile response by increasing cGMP activity in penile blood vessels, helping you achieve and maintain an erection during sexual stimulation. For best results, take it about 30–60 minutes before sex, consider meal timing (especially avoiding heavy, fatty meals right before dosing), and be cautious with alcohol and interacting medicines—particularly nitrates and riociguat.

If you have underlying heart conditions, take medicines that affect blood pressure, or are unsure about interactions, consult a healthcare professional or pharmacist before using sildenafil.
