Fildena Extra Power (Sildenafil Citrate) – Patient Guide (Australia)

Fildena Extra Power contains sildenafil citrate, a medicine used to help achieve and maintain an erection when sexual stimulation occurs. This patient-friendly guide explains how sildenafil works, how to take it, what to expect, common safety considerations, and what to discuss with a healthcare professional.

If you are unsure whether this medicine is suitable for you, or if you have complex medical conditions or take multiple medicines, seek professional advice.

1) Basic product information

2) What is sildenafil and how does it work? (Mechanism of action)

Sildenafil belongs to a class of medicines called PDE5 inhibitors (phosphodiesterase type 5 inhibitors). During sexual stimulation, the body releases nitric oxide, which increases levels of cGMP in the blood vessels of the penis. cGMP helps relax smooth muscle and allows increased blood flow, leading to an erection.

Sildenafil helps by blocking PDE5, an enzyme that normally breaks down cGMP. By reducing cGMP breakdown, sildenafil can enhance the natural erection response to sexual stimulation.

• It supports erections when you are sexually aroused.
• It does not cause an erection by itself without sexual stimulation.
• It may also help improve firmness and reduce difficulty maintaining an erection.

3) Pharmacokinetics (How your body processes it)

Pharmacokinetics describes absorption, distribution, metabolism, and elimination. While individual results vary, typical patterns for sildenafil include:

• Absorption: Sildenafil is absorbed through the gastrointestinal tract. Peak blood levels typically occur within about 30–120 minutes after taking a dose.
• Onset of action: Many people notice effects within about 30–60 minutes, but timing can vary with dose and individual factors.
• Duration: Effects may last for several hours. The practical “window” for sexual activity is often within 4–6 hours, though responses differ.
• Metabolism: Sildenafil is primarily metabolised by liver enzymes (notably CYP3A4).
• Excretion: Metabolites are eliminated mainly via the faeces and urine.

If you take other medicines that affect liver enzymes or blood levels (for example, some antifungals or certain HIV medicines), sildenafil levels may change, influencing effectiveness and side effects.

4) Typical use and timing

Fildena Extra Power is used for erectile dysfunction (ED)—the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. You should take it as needed before sexual activity.

When to take it

• Consider taking sildenafil approximately 30–60 minutes before sexual activity.
• Some people may need up to 2 hours for best effect, especially if food was eaten.
• Allow time to see how your body responds—timing can differ from one person to another.

How often to take it

Follow the dosing instructions supplied with your product. In general, sildenafil is typically used once per day at most for ED. Taking more frequently can increase the risk of adverse effects.

5) Indications: When is sildenafil used?

Sildenafil is indicated for:

• Erectile dysfunction (ED) in adult men, when sexual stimulation is present.

Sildenafil is not intended to be used for female sexual dysfunction. It is also not a cure for underlying causes of ED; it helps manage symptoms by improving the erection response to sexual arousal.

6) Dosing (General guidance)

Dosing depends on your age, overall health, and other medicines you take. Use the strength and instructions provided for your specific Fildena Extra Power product. Below is general, patient-oriented guidance commonly used for sildenafil in ED:

Typical starting approach (general)

• Most adults: start with a lower dose to assess response and tolerability.
• Need for adjustment: if the response is not adequate and side effects are manageable, a clinician may adjust dose (based on the available product strengths).
• Older age or certain health conditions: lower doses may be considered because blood levels can be higher and side effects more likely.

Important dose limits

• Do not exceed once in 24 hours for ED unless instructed otherwise by a healthcare professional.
• Do not “double up” if you do not feel an effect—wait at least 24 hours before the next dose.

If you miss a planned dose, take it only when you intend to have sexual activity and when it fits the timing that works for you.

7) Food interactions (including whether to take with meals)

Food can influence how quickly sildenafil begins to work. In general:

• High-fat meals may slow absorption and delay peak effect. If you eat a heavy or fatty meal before taking sildenafil, you may need to wait longer (sometimes closer to 2 hours).
• Lighter meals may cause less delay and can help you achieve the expected timing.
• Sildenafil can typically be taken with or without food, but for best predictability, many people prefer to avoid a very heavy meal right before taking it.

If you find the dose is “not working,” consider reviewing both your meal timing and other medicines you take.

8) Alcohol and medicine interactions

Alcohol

Alcohol can worsen erection quality in some men. Moderate to heavy drinking may reduce the effectiveness of sildenafil and can increase side effects such as dizziness and low blood pressure.

• If you drink, aim for moderation.
• Avoid driving or operating machinery if you feel lightheaded.
• If you notice flushing, headache, or dizziness after alcohol and sildenafil, consider reducing alcohol next time.

Medicines that can interact strongly (important safety)

Some medicine combinations can be dangerous and should be avoided. The most critical interaction is with medicines that contain nitrates or with certain guanylate cyclase stimulators.

Other common interaction categories

• Alpha-blockers (for prostate symptoms or blood pressure): Some men taking alpha-blockers may be at increased risk of dizziness or low blood pressure. Dose timing and starting with lower sildenafil doses may help, but you should discuss this with a clinician.
• Strong CYP3A4 inhibitors: Medicines that strongly inhibit CYP3A4 can increase sildenafil levels and side effects. Examples may include certain antifungals and some antibiotics. In these cases, a lower sildenafil dose is often needed.
• HIV medicines: Some HIV treatment regimens can raise sildenafil levels.
• Other ED treatments: Do not combine sildenafil with other PDE5 inhibitors (such as tadalafil or vardenafil).
• Blood pressure medicines: Sildenafil can lower blood pressure modestly in some people, potentially amplifying effects of antihypertensives.

“No interaction” isn’t guaranteed

Medication interactions depend on dose, timing, and individual health factors. Before using sildenafil, it’s advisable to review all medicines and supplements you take, including: prescription medicines, over-the-counter products, and herbal supplements (for example, products marketed for sexual performance).

9) Safety profile: Common side effects and when to seek help

Most people tolerate sildenafil well when taken correctly. Side effects are often related to increased blood flow and changes in blood vessels.

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Indigestion or stomach discomfort
• Nasal congestion or a runny nose
• Dizziness
• Blurred vision or sensitivity to light
• Back pain or muscle ache (less commonly)

Seek urgent medical attention if you experience

• Chest pain or severe shortness of breath (especially if it occurs during sexual activity).
• Signs of an allergic reaction such as swelling of the face/lips, widespread rash, or difficulty breathing.
• Sudden vision loss or a serious change in vision.
• Sudden hearing changes or ringing in the ears.
• Prolonged erection (priapism)—an erection lasting 4 hours or more. This needs urgent care.
• Fainting or severe dizziness, which could indicate low blood pressure.

Who should be extra careful?

Discuss sildenafil with a healthcare professional if you have:

• Significant heart disease or unstable chest pain
• Low blood pressure (or episodes of fainting)
• Severe liver or kidney impairment
• A history of stroke
• Eye conditions such as non-arteritic anterior ischaemic optic neuropathy (NAION)
• Anatomical penis problems (for example, Peyronie’s disease)
• Conditions that may predispose to priapism (e.g., certain blood disorders)

10) Practical use tips for best results

• Use sexual stimulation: sildenafil supports erections during arousal; it is not a direct “trigger” on its own.
• Get the timing right: if you ate a heavy meal, consider adjusting timing next time.
• Start lower if you’re sensitive: if you experience headaches or dizziness, you may need a lower dose.
• Stay hydrated: dehydration can worsen dizziness and headache.
• Be mindful of alcohol: large amounts may interfere with erection quality.
• Don’t combine ED medicines: combining PDE5 inhibitors can increase side effects without improving safety.
• Allow the “window”: focus on the 30–120 minute period after dosing, rather than trying multiple times back-to-back.

11) Alternative options

ED can have many causes, including vascular health, hormonal factors, stress, depression, relationship factors, medication side effects, and lifestyle factors. Alternatives may include:

Other medicine options (general)

• Other PDE5 inhibitors: such as tadalafil or vardenafil. Each has different timing and duration characteristics.
• Non-PDE5 options: depending on the underlying cause, clinicians may consider other treatments.

Non-medicine approaches

• Lifestyle changes: regular exercise, maintaining a healthy weight, smoking cessation, and limiting alcohol.
• Psychological support: counselling or sex therapy can be helpful, especially when stress or performance anxiety is involved.
• Addressing contributing conditions: improving diabetes control, cholesterol management, and blood pressure can support sexual health.

If sildenafil is not effective for you after a few correctly timed attempts, it may be worth discussing other options and the underlying cause of ED.

12) Market and legal context in Australia (patient-friendly overview)

In Australia, medicines are regulated by the Therapeutic Goods Administration (TGA). Erectile dysfunction medicines such as sildenafil are generally available only through legitimate supply channels and must comply with Australian rules around quality, safety, and lawful distribution.

When buying online, it’s important to choose a reputable pharmacy and to verify that the product is sourced and supplied lawfully. Always look for clear product information, batch/expiry details where appropriate, and transparent delivery terms.

If you are seeking ED treatment, consider discussing with a healthcare professional to ensure suitability—especially if you take nitrates, have significant cardiovascular conditions, or use interacting medicines.

13) Recent guidance and clinician considerations (practical summary)

Current clinical practice typically emphasises a few key points for PDE5 inhibitors like sildenafil:

• Cardiovascular safety: sexual activity and PDE5 inhibitors should be used cautiously in men with certain heart conditions.
• Medication review: nitrates and certain interacting drugs require strict avoidance due to low blood pressure risk.
• Titration and tolerability: many people benefit from starting at a lower dose and adjusting gradually.
• Time-to-effect matters: correct timing relative to food and arousal improves success rates.
• Rule out underlying causes: persistent ED can be a marker of vascular disease; a healthcare review may be recommended.

If you’ve recently started sildenafil, changed your other medications, or experienced new symptoms, it’s advisable to seek professional advice.

Will sildenafil guarantee an erection?

No. Sildenafil helps improve blood flow and supports erections during sexual stimulation. Stress, relationship factors, anxiety, underlying medical issues, and incorrect timing can all affect results.

What if it doesn’t work the first time?

If you didn’t respond as expected, it may be due to timing, food, alcohol, dose adequacy, or interactions with other medicines. Avoid taking more frequently than allowed; instead, consider discussing dose/timing adjustments with a healthcare professional.

Can I take it with alcohol?

Moderate alcohol may be tolerated, but heavy drinking can worsen erection quality and increase side effects like dizziness or headaches. Keep alcohol intake moderate and avoid unsafe activities if you feel unwell.

What medicines must not be taken with sildenafil?

Do not take sildenafil with nitrates (such as glyceryl trinitrate/nitroglycerin or isosorbide medicines) or with riociguat. Other interactions may also occur with alpha-blockers and certain antibiotics/antifungals and HIV medicines. Review all medicines with a healthcare professional when possible.

Are there any warning signs I should watch for?

Seek urgent help if you experience chest pain, fainting, a serious allergic reaction, sudden vision or hearing changes, or an erection lasting 4 hours or more.

Can sildenafil be used if I have heart disease?

People with heart conditions must be careful because sexual activity and blood pressure changes can pose risks. Sildenafil may be unsuitable depending on your condition and medications. Discuss with a healthcare professional before use.

Is it safe to combine with another ED medicine?

Avoid combining sildenafil with other PDE5 inhibitors. Combining ED medicines can increase side effects and risks without better outcomes.
