Filitra (Vardenafil): Comprehensive Patient Information for Australian Users
1. Basic Product Information
| International Nonproprietary Name (INN) | Vardenafil |
|---|---|
| Brand Names in Australia | Filitra, Levitra, Vivanza (Filitra is an alternative international brand) |
| ATC Code | G04BE09 |
| Available Forms and Strengths | Oral tablets: 5 mg, 10 mg, 20 mg |
| Manufacturers | Bayer AG, Ajanta Pharma, various generic suppliers |
| Prescription Status | Prescription Only (Schedule 4, S4) in Australia |
2. Mechanism of Action
- Simple Explanation: Filitra (vardenafil) works by helping the blood vessels in the penis relax, making it easier to get and maintain an erection when sexually aroused.
- For Specialists: Vardenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. It enhances the effect of nitric oxide by inhibiting PDE5 in the corpus cavernosum, resulting in increased cyclic guanosine monophosphate (cGMP) and smooth muscle relaxation.
3. Pharmacokinetics
- Absorption: Rapidly absorbed orally; peak plasma concentrations occur within 30 to 120 minutes (median ~1 hour).
- Metabolism: Extensive hepatic metabolism via CYP3A4, CYP3A5, and to a minor extent CYP2C enzymes.
- Elimination: Mainly as metabolites, via faeces (91-95%) and urine (2-6%).
- Duration of Action: Usually effective for up to 4–6 hours post-dose.
4. Use in Everyday Life and Best Practices (Australian Context)
Filitra is used as needed for the treatment of erectile dysfunction (ED) in adult men. The typical recommended starting dose is 10 mg, taken about one hour before planned sexual activity. It may be adjusted to 5 mg or up to 20 mg depending on efficacy and tolerability. It is suitable for diverse Australian lifestyles and is not intended for women or children.
Do not take more than one dose in a 24-hour period. Always consult your GP or pharmacist before changing your dose.
5. Dosing: Morning vs Evening
- Morning: May suit those planning intimacy earlier in the day; less interference from heavy evening meals or alcohol, which can slow absorption.
- Evening: Most common use; however, heavy suppers or alcohol may delay effectiveness. Aim for a light meal or empty stomach for optimal effect.
- Regularity: For best results, take at the same time relative to anticipated activity. Avoid creating a fixed daily schedule—Filitra is for use as needed, not as a daily medicine.
6. Taking With Food or on an Empty Stomach
- Taking Filitra with a light meal or on an empty stomach leads to the fastest effect.
- High-fat meals (e.g., a full English breakfast, heavy pub fare) can significantly delay absorption and reduce effectiveness.
- If you prefer dining before intimacy, keep it light—grilled fish, chicken salad, or steamed vegetables are suitable options for Australian diets.

11. Guidelines for Proper Use (Australian Clinical Context)
- Take Filitra only as directed by your prescriber—never exceed the recommended dose.
- Read the Australian Consumer Medicine Information (CMI) leaflet supplied with your medicine.
- Store Filitra in a cool, dry place below 25℃ and out of reach of children.
- If you experience chest pain during or after sex, seek medical help immediately.
- Report any sudden vision or hearing loss at once.
- For Aboriginal and Torres Strait Islander peoples, or for those with multiple chronic illnesses, extra consideration and medical consultation may be necessary.
12. Alternative Treatment Options
- Sildenafil (Viagra, generic): Cheapest; works in 30-60 minutes; effect lasts around 4 hours. May cause more visual side effects.
- Tadalafil (Cialis, generic): Effect lasts up to 36 hours. Can be taken daily at lower doses or as needed. May interact more with blood pressure medications.
- Avanafil (not widely available in Australia): Fastest onset (15-30 minutes). Limited evidence and access.
Note: All PDE5 inhibitors require prescription in Australia and are not covered by the PBS for ED. Prices vary by pharmacy and product brand.
13. Legal, Registration, and Reimbursement Status in Australia
- Regulation: Registered with the Therapeutic Goods Administration (TGA).
- Legal classification: Schedule 4 (S4) Prescription Only Medicine.
- Reimbursement: Not subsidised for erectile dysfunction under the Pharmaceutical Benefits Scheme (PBS). Payment is privately funded.
- Supply: Dispensed by Australian-registered pharmacies.
14. Latest Research and Clinical Guidance (2022–2025)
- A 2023 systematic review published in The Lancet Regional Health – Western Pacific reaffirmed vardenafil’s position as an effective and safe option for ED, especially among men with diabetes or post-prostatectomy.
- The 2024 Australian guidelines (RACGP) recommend PDE5 inhibitors, including vardenafil, as first-line therapy, provided there are no contraindications such as nitrate use.
- Ongoing studies (2022–2025) emphasise individualised therapy and the importance of considering cardiovascular risk, mental health, and partner involvement in management.
- No essential new warnings or regulatory changes (as of Q2 2024) for vardenafil in Australia.

16. Frequently Asked Questions (FAQ)
Q1. How quickly does Filitra (vardenafil) work?
Most men experience effects 30 to 60 minutes after taking a dose. Sexual stimulation is still required for an erection to occur.
Q2. Can I drink alcohol if I take Filitra?
Small amounts of alcohol are unlikely to interfere—but heavy drinking may reduce the effect and increase side effects such as low blood pressure, dizziness, and headache.
Q3. Do I need to take Filitra every day?
No. Take Filitra only as needed, before sexual activity, and never more than once per 24 hours.
Q4. Is Filitra safe for all men with erectile dysfunction?
Not necessarily. If you have significant heart, liver, or kidney disease, or take medicines containing nitrates, vardenafil may be unsafe. Always discuss all your medications and health conditions with your GP.
Q5. Will Filitra cause an erection without sexual stimulation?
No. Filitra works only in conjunction with sexual arousal—it will not cause automatic or spontaneous erections.
