Mechanism of Action
For Patients: Vardenafil helps men achieve and maintain an erection by boosting the natural process that occurs during sexual arousal. It works by improving blood flow to the penis.
For Specialists: Vardenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. By inhibiting PDE5, it increases levels of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum, resulting in vasodilation and improved erectile function. It is only effective in the presence of sexual stimulation.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration; peak plasma concentrations reached in approximately 30–60 minutes.
- Metabolism: Extensively metabolized by liver enzymes (CYP3A4, CYP3A5, CYP2C9).
- Elimination: Half-life of 4–5 hours; eliminated mainly via the liver, with metabolites excreted in the faeces and urine.
- Duration of Action: Up to 4–6 hours; sexual response possible with stimulation during this window.
Use in Everyday Life & Best Practices (Australia)
Levitra Professional is most often prescribed as a single, on-demand dose prior to anticipated sexual activity. The recommended starting dose is usually 10 mg, taken about 25–60 minutes before sex. Your healthcare provider may adjust the dose to a maximum of 20 mg, or lower it to 5 mg, depending on your response and any potential side effects.
- Take only one tablet in any 24-hour period.
- Sexual stimulation is required for the medicine to work.
- Suitable for most forms of erectile dysfunction, including after prostate surgery, diabetes, and psychological causes.
- Store in a cool, dry place, away from direct sunlight (ideally under 25°C, typical of Australian medicine storage guidelines).
Dosing: Morning vs Evening
The timing of your dose can be tailored to your and your partner’s preferences:
- Morning Use: May be preferred if intimacy is planned for the day, but food intake and daily routines can affect absorption.
- Evening Use: Most patients in Australia prefer evening use as it coincides with typical social and relationship habits. Less likely to interfere with work or daily activities. Also, fasting states are more common in the evenings, optimising absorption.
- Tip: Try to take the tablet around the same time prior to sexual activity for more predictable results.
Taking with Food or an Empty Stomach (Australian Dietary Habits)
- Levitra Professional may be taken with or without food.
- However, high-fat meals common in some Australian diets (e.g. traditional “full English” breakfasts, burger meals) can delay the absorption and reduce the speed of onset.
- For fastest results, take on an empty stomach or after a light meal.
- Alcohol may increase certain side effects (see below).

Safety Profile / Side Effects
- Common: Headache, flushing, nasal congestion, upset stomach, dizziness.
- Occasional: Back pain, vision changes (mild, temporary), indigestion.
- Rare/Serious: Priapism (painful, prolonged erection >4h), sudden vision or hearing loss, severe allergic reaction, significant drop in blood pressure.

Guidelines for Proper Use
- Always take as directed by your Australian prescriber or pharmacist.
- Do not exceed the prescribed dose.
- Take whole with water, or allow to dissolve (Professional form) as instructed.
- If you miss a scheduled dose, wait until the next time you plan sexual activity — do not double up.
- Discuss any other conditions, medications, or supplements with your GP/pharmacist prior to starting.
- Monitor for side effects the first few times and report anything concerning.
Alternative Treatment Options
- Sildenafil (Viagra, generic): Similar effect, more established, often PBS-reimbursed for some conditions; slightly longer onset and duration than vardenafil.
- Tadalafil (Cialis, generic): Longer half-life (up to 36h), “weekend pill,” may be taken daily; broader PBS reimbursement (including some LUTS indications).
- Avanafil (not currently PBS listed): Faster onset, slightly fewer interactions.
- Non-pharmacological: Vacuum erection devices, penile implants, psychological therapies.
Your pharmacist or doctor can guide you toward the most appropriate and cost-effective choice for your situation.
Legal, Registration, and Reimbursement Status in Australia
- Registered with the Therapeutic Goods Administration (TGA).
- Schedule 4 (S4) - prescription required from a licensed Australian prescriber.
- Not routinely reimbursed by the PBS for typical erectile dysfunction (except for certain chronic conditions such as spinal cord injury).

Latest Research & Clinical Guidance (2022–2025)
- Levitra Professional and Vardenafil continue to be recommended as first-line therapy for erectile dysfunction per Australian and international urological guidelines (Urological Society of Australia and New Zealand, EAU, AUA 2022–2024).
- Recent comparative studies (Ozturk et al, 2023; Trussell et al, 2024) show similar effectiveness between PDE5 inhibitors, with vardenafil often preferred for its favorable side effect profile, especially less visual disturbance than sildenafil.
- TGA guidance (2023 update) reaffirms contraindications and safe use parameters.
- Ongoing research explores microdose regimens and combination therapies, but these are not yet standard practice.
