Mechanism of Action
In Simple Terms: Vardenafil helps improve erections in men with erectile dysfunction (ED) by increasing blood flow to the penis. It works only when sexually stimulated. This leads to a firmer, longer-lasting erection.
For Specialists: Vardenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. It enhances nitric oxide-mediated vasodilation by blocking PDE5-enzyme degradation of cyclic guanosine monophosphate (cGMP) in cavernosal tissue. This results in smooth muscle relaxation and increased penile blood inflow.
Pharmacokinetics
- Absorption: Rapid; peak plasma concentration after 30–120 minutes (median ~1 hour).
- Metabolism: Hepatic (liver), primarily via CYP3A4, minor via CYP3A5 and CYP2C isoenzymes.
- Elimination: Mostly via faeces (major), urine (minor); terminal half-life approx. 4–5 hours.
- Duration of Action: Up to 8 hours, with some effects possible up to 12 hours post-dose.
Use in Everyday Life & Best Practices
Vardenafil is prescribed mainly to adult men with erectile dysfunction, regardless of cause (vascular, psychological, mixed). In Australia, doctors individualise therapy with a typical prescribed dose of 10 mg taken as needed, 25–60 minutes before anticipated sexual activity. Do not take more than one dose per day.
- Start with 10 mg.
- Dose can be increased to 20 mg or decreased to 5 mg based on efficacy and side effects.
- Sexual stimulation is required for the medicine to work.
- Avoid splitting tablets without pharmacist advice as it risks inaccurate dosing.
Seek medical assessment before starting, especially if over 65, with heart/liver conditions, or on other medicines.
Dosing in the Morning vs Evening
- Morning Use: May be preferred for planned daytime sexual activity; consider potential for side effects such as headache, flushing, or dizziness in work settings.
- Evening Use: Common; aligns with typical intimacy times. Slight delay if used after a heavy dinner (see below).
- Tip: Take at a consistent time if a regular pattern is needed, but not more than once daily.
Taking with Food or on an Empty Stomach
- Empty Stomach: Faster onset; optimal within 1 hour.
- With Food: No significant effect with light, healthy meals. High-fat, rich meals (e.g., steak, creamy sauces, classic pub “surf and turf”) may delay absorption and reduce maximum effect.
- Advice for Australians: If planning a full meal (barbecue, fish and chips), consider taking Vardenafil before eating or wait at least 2 hours after a big meal.
Interaction Warnings
| Interaction | Details/Advice |
|---|---|
| Alcohol | Small amounts generally safe; excessive drinking increases risk of side effects (dizziness, low blood pressure) and reduces performance. |
| Food (High Fat) | May delay absorption and weaken effect. Prefer lighter meals. |
| Other Medicines |
|
| Grapefruit & Juice | Can boost side effects or delay clearance due to CYP3A4 inhibition; avoid. |
Indications
| Indication | Status/Details |
|---|---|
| Erectile Dysfunction (ED) | Approved indication |

| Raynaud’s Phenomenon | Very limited, experimental/off-label use |
Dosing According to Clinical Indications
| Patient Group | Recommended Dose | Special Notes |
|---|---|---|

Guidelines for Proper Use – Australia-Specific Tips
- Remove tablet from the blister only when ready; swallow whole with water.
- Do not crush or chew tablet unless using orodispersible formulation (which is placed on the tongue to dissolve).
- Keep to prescribed dose, never share with others.
- Store at room temperature out of direct sunlight – typical for most Australian homes.
- Report chest pain, vision changes or a prolonged erection (priapism) to a medical service immediately.
- Check for drug interactions with your pharmacist, including over-the-counter medicines and supplements—pharmacists are your partners in medication safety across all Australian states and territories.
- Review heart risk with your GP or cardiologist if you have cardiovascular disease.
Alternative Treatment Options
- Sildenafil (Viagra, generics): Most commonly used PDE5 inhibitor, available by prescription. Pros: Extensive experience, often less expensive. Cons: Must be taken on an empty stomach for best results; lasts 4–6 hours.
- Tadalafil (Cialis): Longer-acting; suitable for on-demand or daily dosing. Pros: Up to 36-hour effect, flexible use. Cons: Some side effects last longer; daily cost may be higher.
- Alprostadil (Caverject, MUSE): Second-line; injectable or urethral pellet. Pros: Effective if oral agents fail; Cons: Invasive, risk of discomfort or local side effects.
- Testosterone replacement: For confirmed deficiency by blood tests only. Pros: Addresses hormone imbalance. Cons: Not suitable for all; requires close monitoring.
- Non-drug options: Lifestyle modifications (weight loss, exercise, decreased alcohol/tobacco), vacuum erection devices, psychological counselling for performance anxiety or relationship factors.
Reimbursement: Currently, oral ED treatments (including Valif/Vardenafil) are not covered by the Australian PBS for general use and are private “out-of-pocket” medicines. Some hospital or DVA schemes may support access for defined medical conditions.
Legal, Registration, and Reimbursement Status in Australia
- Regulatory authority: Therapeutic Goods Administration (TGA).
- Prescription Schedule: S4 (prescription medicine) — prescription required.
- PBS status: Not routinely reimbursed under the Pharmaceutical Benefits Scheme (PBS) for erectile dysfunction.
- Importation: Permitted for personal use under Special Access or Personal Importation Scheme with valid script; local pharmacy supply preferred for ongoing therapy.
- Pharmacy guidance: Sale or supply only by or under pharmacist/medical supervision.
Latest Research & Clinical Guidance (2022–2025)
- Recent Australian clinical guidelines (ASHM, Urological Society of Australia and New Zealand) continue to recommend PDE5 inhibitors (including Vardenafil) as first-line therapy for psychogenic, organic, and mixed erectile dysfunction in men who are not taking nitrate medicines.
- Meta-analysis studies (e.g., Yafi et al., 2023 Eur Urol) reaffirm efficacy and safety across age groups; individualized dose adjustment is key for success and minimising adverse events.
- Use in cardiovascular disease: Cautious use in stable cardiac patients; not for men using nitrates or who are high cardiac risk (see Samuel J et al., Med J Aust 2024).
- Emerging formulations: Orodispersible tablets offer benefit for those with swallowing difficulty or needle phobia, under study in Australian context (TGA publication, April 2024).

Frequently Asked Questions (FAQ)
- How long before sexual activity should I take Valif/Vardenafil?
Most men get the best results by taking 1 tablet 30–60 minutes before planned sexual activity. - Can I drink alcohol with this medicine?
Moderate alcohol is generally safe, but heavy use increases side effects and may reduce effectiveness. Best avoided or kept to a minimal amount. - Will I get an erection without sexual stimulation?
No. Vardenafil helps achieve and maintain an erection only with sexual arousal. - Can I take this medication if I have heart disease?
Possibly, but only under specialist/GP supervision. Never if you use nitrates or have unstable heart disease—risk of dangerous blood pressure drop. - Are there natural alternatives to this medicine?
Regular exercise, weight control, managing high blood pressure or diabetes, and not smoking can all improve sexual health. Psychological therapy is important if stress or relationship issues are significant factors.
