Fildena Professional (Sildenafil Citrate) — Patient Information (Australia)

Fildena Professional contains sildenafil citrate, a medicine used to treat erectile dysfunction (ED). It works by supporting blood flow to the penis during sexual stimulation. This guide is written to help you understand what the medicine does, how to use it safely, and what to consider for typical daily life in Australia.

Always read the packaging and any enclosed consumer medicine information. If you have questions about your situation—especially if you take other medicines or have heart/blood pressure conditions—speak with a qualified healthcare professional.

1) Basic product information

• Medicine: Fildena Professional
• Active ingredient: Sildenafil citrate
• Common use: Erectile dysfunction (ED)
• Therapeutic class: PDE5 (phosphodiesterase type 5) inhibitor
• How it works: Helps increase blood flow during arousal
• Typical forms: Oral tablets (strengths vary by product)

Strengths and product presentation can differ between markets and batches. Check the label for the exact tablet strength (e.g., 25 mg, 50 mg, or 100 mg if applicable).

2) How Fildena Professional works (mechanism of action)

Sildenafil belongs to a group of medicines called PDE5 inhibitors. During sexual arousal, your body releases chemical signals that relax smooth muscle tissue in the penis and increase blood flow.

The natural process involves nitric oxide, which helps produce cGMP (cyclic guanosine monophosphate). PDE5 breaks down cGMP, limiting the erectile response. Sildenafil helps by inhibiting PDE5, so cGMP lasts longer, supporting improved blood flow when you are sexually stimulated.

• Not an aphrodisiac: It does not increase desire by itself.
• Needs sexual stimulation: Effect is most reliable when arousal occurs.
• Target effect: Helps improve the ability to get and maintain an erection firm enough for sex.

3) Pharmacokinetics (how the body handles sildenafil)

Pharmacokinetics describe how quickly and for how long a medicine acts. While individual responses vary, the general pattern for sildenafil is:

• Absorption: Sildenafil is absorbed after an oral dose.
• Time to peak effect: Blood levels typically rise within about 30–120 minutes (often sooner for some people).
• Duration: Many people experience effects for up to 4 hours, sometimes longer depending on the dose, metabolism, and individual factors.
• Metabolism: Primarily metabolised in the liver via CYP450 enzymes.
• Elimination: Sildenafil and metabolites are cleared mainly through hepatobiliary (bile) and renal (kidney) pathways.

Because the medicine is processed by the liver, people with liver impairment may experience stronger or longer effects and may need adjusted dosing (discuss with a clinician).

4) Typical use and timing

When to take it

Fildena Professional is generally taken as needed before sexual activity.

• Suggested timing: Take the tablet about 30 to 60 minutes before sex.
• Flexibility: Some people may benefit from taking it closer to 60–90 minutes, especially if meals were eaten.
• Maximum frequency: Do not take more often than recommended on the product label or by a healthcare professional.

What to expect

• You may notice improved erection quality once the medicine starts working.
• Response varies between individuals, particularly with factors like baseline health, arousal, stress, and alcohol intake.
• If you do not get the expected effect, do not simply increase the dose without medical guidance.

5) Indications (when Fildena Professional is used)

Fildena Professional (sildenafil citrate) is used for the treatment of:

• Erectile dysfunction (ED): Difficulty achieving and/or maintaining an erection suitable for satisfactory sexual activity.

Sildenafil is not indicated for treating low libido or for improving fertility.

6) Recommended dosing (general guidance)

Dosing depends on your situation, including other medicines, age, liver function, and tolerability. The information below is general and may not match your exact tablet strength.

• Typical adult starting approach: Many regimens start at a lower dose and adjust based on effect and side effects.
• Common dosing frequency: Usually taken as needed before sexual activity, with spacing between doses.

Important safety note: If you take medicines for heart/blood pressure or certain urinary/prostate conditions, the safest dose and frequency may differ. Some combinations are not suitable.

Do not exceed label instructions

Always follow the dosing directions on your specific product. Avoid taking additional ED medicines at the same time.

7) Food interactions (what you should know about meals)

Food can influence how quickly and reliably sildenafil starts working.

• Fatty meals: Eating a heavy or high-fat meal before taking sildenafil may delay onset and reduce how quickly it works.
• Timing adjustment: If you plan a large meal, consider taking the tablet closer to 60–90 minutes beforehand (or discuss timing with a clinician/pharmacist).
• Light meals: Many people find sildenafil works more predictably when taken after a lighter meal or with less food volume in the stomach.

8) Alcohol interactions

Alcohol can affect erectile function by influencing blood vessels, nervous system responses, and sexual performance. It can also increase the risk of side effects such as dizziness, headache, and reduced blood pressure.

• Moderation is key: Keep alcohol intake moderate, especially when taking sildenafil.
• Avoid binge drinking: Higher alcohol intake can make it harder to achieve an erection and may worsen adverse effects.
• Be cautious driving: If you feel light-headed, do not drive or operate machinery.

If you experience marked dizziness or symptoms of low blood pressure after combining alcohol and sildenafil, seek medical advice.

9) Medicine interactions (especially important)

Sildenafil can interact with certain medicines, mostly through effects on blood pressure and liver metabolism. Below are key interaction categories to know about.

Never combine with nitrates

Do not use sildenafil with nitrates (for example, medicines used for angina/heart pain), because both can lower blood pressure significantly. This is a serious safety concern.

Use caution with “riociguat”

• Riociguat (used for certain lung blood pressure conditions) is not suitable with PDE5 inhibitors due to additive blood pressure effects.

Alpha-blockers (prostate/urinary symptoms and blood pressure)

Some people take alpha-blockers (often for urinary symptoms or hypertension). Combining with sildenafil may cause symptomatic low blood pressure in certain circumstances.

• Tell a healthcare professional/pharmacist about any alpha-blocker you take.
• Your dosing schedule may need adjustment.

Other ED treatments

• Avoid taking sildenafil alongside other PDE5 inhibitors (e.g., tadalafil, vardenafil, or similar) during the same timeframe.
• Do not mix multiple ED medicines unless a clinician specifically advises it.

Blood pressure medicines

Sildenafil may have additional blood pressure-lowering effects when combined with other antihypertensive medicines. Many people still use it safely, but caution is warranted—particularly if you already have low blood pressure, fainting episodes, or take multiple blood pressure drugs.

Medicines that affect liver enzymes (CYP450)

Sildenafil is processed by liver enzymes (notably CYP3A4). Drugs that strongly inhibit these enzymes may increase sildenafil levels and side effects.

• Examples of inhibitors may include certain antifungals and some antibiotics (specific medicines vary).
• Always inform your pharmacist about all medications, including over-the-counter products and herbal supplements.

“Do not forget to mention” list

Before using Fildena Professional, consider discussing or checking the following with a clinician/pharmacist:

• Nitrates (including some chest pain medicines)
• Riociguat
• Alpha-blockers (e.g., for urinary symptoms)
• Multiple blood pressure medicines
• Antifungals/antibiotics that may affect drug metabolism
• Other ED medicines
• Recreational “poppers” or nitrite products (commonly associated with dangerous interactions)

10) Safety profile and common side effects

Like all medicines, sildenafil can cause side effects. Many are mild and temporary. However, some effects can be serious and need prompt medical attention.

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Dyspepsia (indigestion) / stomach discomfort
• Stuffy nose
• Dizziness
• Visual changes (e.g., increased sensitivity to light or a bluish tint) in some people

Serious side effects — get urgent help

Seek immediate medical assistance if you experience:

• Chest pain or symptoms suggestive of a heart problem
• Fainting or severe dizziness
• Prolonged erection (priapism) lasting longer than what is considered safe—prompt treatment is critical
• Sudden vision loss or severe eye pain
• Sudden hearing changes (rare)
• Signs of severe allergic reaction such as facial/lip swelling, trouble breathing, or widespread rash

Who should be extra cautious

• People with significant heart disease or unstable cardiovascular status
• People with very low blood pressure or a history of fainting
• People with severe liver impairment
• People with certain blood disorders or conditions predisposing to priapism
• Anyone taking interacting medications (especially nitrates)

11) Practical use tips (making results more reliable)

• Allow adequate time: Take it 30–60 minutes before sex (adjust up to 90 minutes if you had a heavy meal).
• Use with sexual stimulation: Sildenafil supports blood flow during arousal; it does not create desire.
• Choose a comfortable setting: Stress and anxiety can reduce performance regardless of medicine.
• Limit alcohol: Keep drinks moderate to reduce dizziness and performance issues.
• Stay hydrated: Dehydration can worsen headaches and dizziness.
• Keep notes: Track dose, timing, meal size, alcohol, and results to identify what works best for you.
• Do not “stack doses”: If it doesn’t work as expected, consult a pharmacist or clinician before taking more.

12) Alternative options

Erectile dysfunction can have physical and psychological causes, and the best approach depends on your health profile and preferences. Alternatives include:

Other PDE5 inhibitors

• Tadalafil (often longer duration for some people)
• Vardenafil
• Avanafil

Non-medicine options

• Address lifestyle factors: reduce smoking, manage weight, improve sleep, and increase physical activity
• Manage diabetes, cholesterol, and blood pressure with your usual care team
• Psychological support if anxiety, stress, or relationship factors contribute
• Vacuum erection devices (mechanical assistance)
• Other medical approaches in select cases (e.g., penile injections or implants are specialist-led)

If ED is new, worsening, or associated with chest pain or shortness of breath, seek medical advice promptly to evaluate cardiovascular health.
