Fildena Professional (Sildenafil Citrate) — Patient Information (Australia)
Fildena Professional contains sildenafil citrate, a well-known medicine used to treat erectile dysfunction. This page explains how it works, when to take it, what to expect, and key safety considerations. It is written to help you understand the medicine in a clear, patient-friendly way.
Important: Do not take sildenafil if you are advised not to use medicines of this type. If you have medical questions or complex conditions (such as heart disease or multiple medications), consult a healthcare professional.
1) Basic product information
| Product | What it contains | Common use | How it is usually taken |
|---|---|---|---|
| Fildena Professional | Sildenafil citrate | Erectile dysfunction (ED) | By mouth, as needed before sexual activity |
Strength: Fildena Professional is commonly available in multiple sildenafil strengths (e.g., 50 mg and 100 mg). Always confirm the exact strength on your pack or product listing.
Medicine type: PDE5 inhibitor (phosphodiesterase type 5 inhibitor).
2) What sildenafil does (mechanism of action)
Sildenafil works by enhancing the natural blood flow response to sexual stimulation.
- During sexual arousal, nitric oxide is released in the erectile tissue.
- This activates an enzyme pathway that increases cGMP (cyclic guanosine monophosphate).
- PDE5 is an enzyme that breaks down cGMP.
- Sildenafil blocks PDE5, allowing cGMP to remain active longer.
- The result is improved blood flow to the penis, helping achieve and maintain an erection sufficient for sexual activity.
Key point: Sildenafil does not automatically cause an erection. Sexual stimulation is still required.
3) Pharmacokinetics (how your body handles it)
Pharmacokinetics describe absorption, distribution, metabolism, and elimination.
- Absorption: Sildenafil is absorbed after oral dosing. Peak levels in the blood usually occur within about 30 to 120 minutes (time varies between people).
- Onset: Some people notice effects in as little as ~30 minutes, while others may take longer.
- Duration: The effect can last for several hours. Many patients find it most useful within a 4-hour window after dosing, though individual responses vary.
- Metabolism: Primarily processed by the liver via enzymes (notably CYP3A4).
- Elimination: Metabolites are removed mainly via the faeces and urine.
Half-life: The elimination half-life is commonly reported around 3 to 5 hours. This contributes to its multi-hour activity.
4) Typical use and when it works best
Sildenafil is typically used for erectile dysfunction (ED)—difficulty achieving or maintaining an erection. It may be used as needed rather than every day, depending on your doctor’s plan and your health profile.
Timing for best results
- Take sildenafil approximately 30 to 60 minutes before sexual activity for many people.
- If you prefer, some may try taking it up to 2 hours before sex to allow for peak effect (especially if you are less sensitive to earlier onset).
- Plan around how heavy a meal you have eaten, because food can affect absorption (see “Food interactions”).
What to expect
- It helps improve blood flow and erection quality with sexual stimulation.
- Results vary based on underlying health conditions (e.g., diabetes, vascular health), stress, and overall lifestyle.
- If you don’t respond the first time, some adjustments in timing or side-effect management may help—avoid changing dose without guidance.
5) Indications (approved uses)
In Australia and many comparable settings, sildenafil is indicated for:
- Erectile dysfunction (ED): To help achieve and maintain an erection during sexual activity.
It is not intended for use in women, and it is not a treatment for sexual arousal problems unrelated to erectile function.
6) Dosing guidance (general information)
Important: Always follow the dosing instructions on your product packaging or advice from your healthcare professional. Dosing may be adjusted for age, health status, and other medicines.
General adult “as needed” approach for ED:
- Common starting doses may be 50 mg.
- Depending on tolerability and effectiveness, doses may be adjusted to 100 mg or reduced to 25 mg.
Maximum frequency: Do not take sildenafil more often than advised on the pack and by healthcare guidance. Many ED regimens use dosing no more than once per day (24-hour period), but the exact direction on your product label should be followed.
Special situations where dose may differ
- Older adults: You may have different tolerance; the safest dose often starts lower.
- Liver problems: Reduced clearance can increase exposure; dose adjustment is often needed.
- Kidney impairment: May require lower doses depending on severity.
- Taking certain interacting medicines: Some drugs increase sildenafil levels (see “Alcohol and medicine interactions”).
7) Food interactions
Food can affect how quickly sildenafil is absorbed.
- High-fat meals: Taking sildenafil after a heavy or high-fat meal may delay onset and reduce or slow the effect.
- Smaller, lighter meals: Often improve predictability and may help sildenafil work closer to the expected onset time.
- Hydration and routine: Staying well-hydrated and maintaining a consistent meal pattern can help you learn your personal timing.
Practical tip: If you plan a larger meal, consider taking sildenafil a bit earlier (within safe limits) or choosing a lighter meal beforehand.
8) Alcohol interactions
Alcohol can worsen erectile dysfunction and may increase the chance of side effects.
- Reduced effectiveness: Alcohol can impair sexual performance and erection quality.
- Blood pressure effects: Sildenafil can lower blood pressure somewhat. Alcohol, particularly in larger amounts, may contribute to dizziness or light-headedness.
- Increased side effects: Higher alcohol intake may increase headaches, flushing, or nausea.
Safety approach: For best results, keep alcohol moderate. Avoid binge drinking and be cautious if you feel dizzy.
9) Medicine interactions (including emergency medicines)
Some medicines interact with sildenafil in ways that can be unsafe or require dose adjustment. The most critical interactions involve nitrates and certain blood pressure medicines.
Do not combine with nitrates
Sildenafil can interact dangerously with medicines that contain nitrates (or “nitric oxide donors”) used for chest pain (angina) or other conditions.
- Examples of nitrates: glyceryl trinitrate (GTN), isosorbide mononitrate/dinitrate, and other nitrate preparations.
- Why it matters: The combination can cause a significant drop in blood pressure.
Emergency note: If you have chest pain, follow your prescribed emergency plan. Let clinicians know you’ve taken sildenafil.
Use caution with “riociguat”
Medications containing riociguat for certain lung conditions can interact with PDE5 inhibitors and should not be used together.
Blood pressure medicines and alpha-blockers
- Alpha-blockers (often used for prostate symptoms or hypertension) may lower blood pressure.
- The combination can increase dizziness or low blood pressure risk.
- Dose timing and initiation strategy may be needed, especially when starting sildenafil.
Medicines that affect sildenafil levels
Sildenafil is metabolised mainly by CYP3A4. Medicines that strongly affect this enzyme may increase sildenafil exposure.
- Stronger inhibitors can increase sildenafil levels and side effects (e.g., some antifungals and certain antibiotics/antivirals).
- Inducers may reduce sildenafil effectiveness.
If you take medicines for infections, fungal conditions, HIV, or other long-term conditions, it’s important to review interactions.
Other ED treatments
Do not combine sildenafil with other PDE5 inhibitors or multiple ED products unless advised by a clinician.
“Lifestyle” interactions that matter
- Recreational drugs that affect blood vessels or blood pressure can be risky.
- Grapefruit or grapefruit juice may affect sildenafil metabolism due to enzyme inhibition in some people.
10) Safety profile and possible side effects
Most people tolerate sildenafil reasonably well, but side effects can occur. Many side effects are dose-related.
Common side effects
- Headache
- Flushing (warmth, redness)
- Indigestion or nausea
- Dizziness
- Stuffy nose
- Visual disturbances (e.g., mild blurring, colour tinge)
Seek urgent medical help if you experience:
- Chest pain (especially if you took sildenafil)
- Severe dizziness or fainting
- Sudden vision loss or severe visual changes
- Sudden hearing loss or significant ringing in the ears
- Priapism (an erection lasting 4 hours or more
- Allergic reactions such as swelling of the face/lips or difficulty breathing
Who should be extra cautious
- Men with known cardiovascular disease or conditions where sex is not considered safe without evaluation
- People with very low blood pressure or unstable blood pressure conditions
- Individuals with severe liver disease
- Those with a history of non-arteritic anterior ischemic optic neuropathy (NAION) in some sildenafil users
- Those with blood cell disorders that predispose to prolonged erections (e.g., sickle cell disease)
11) Practical use tips (to improve comfort and effectiveness)
- Take it at the right time: Aim for 30–60 minutes before sex (or adjust based on your experience).
- Keep meals lighter: Avoid heavy, high-fat meals close to dosing if you want more predictable onset.
- Limit alcohol: Moderate alcohol helps reduce dizziness and improves erection quality.
- Use sexual stimulation: Sildenafil supports the process; it does not replace arousal.
- Start low if advised: If you’re sensitive to side effects or taking interacting medicines, a lower dose may be safer.
- Plan for safety: Be cautious with activities that require alertness if you feel light-headed.
- If it doesn’t work: Sometimes timing, meal effects, anxiety, or other medical issues play a role. Don’t keep escalating the dose on your own.
12) Alternative options
If sildenafil doesn’t suit you or isn’t effective, there are alternatives available. Options may include other PDE5 inhibitors or non-medicine treatments depending on your circumstances.
Other PDE5 inhibitor options
- Tadalafil (often has a longer duration for some people)
- Vardenafil
- Avanafil
Non-medicine approaches
- Lifestyle changes: improving cardiovascular health, exercise, weight management, smoking cessation
- Manage contributing conditions: diabetes, high blood pressure, high cholesterol
- Psychological support: stress, anxiety, relationship factors
- Vacuum erection devices or penile injections (doctor-guided options)
- Hormone evaluation if low testosterone is suspected
Your best choice depends on your health profile, other medications, and preferences for onset/duration.
13) Australia market and legal context (patient-friendly overview)
Medicines in Australia are regulated through the Therapeutic Goods Administration (TGA). Some ED medicines may be available only under specific access arrangements, and requirements can vary by product and formulation.
