Mechanism of Action
For Patients: Levitra (vardenafil) is a treatment for erectile dysfunction (ED). It works by helping blood vessels in the penis relax and widen, which allows more blood to flow in during sexual arousal, helping you achieve and maintain an erection. It does not cause an erection on its own—sexual stimulation is still required for it to work.
For Healthcare Providers: Vardenafil selectively inhibits phosphodiesterase type 5 (PDE5) in the corpus cavernosum. By blocking PDE5, it prolongs the effect of nitric oxide-mediated activation of cyclic guanosine monophosphate (cGMP), resulting in enhanced smooth muscle relaxation and increased penile blood flow during sexual stimulation.
Pharmacokinetics
- Absorption: Rapidly absorbed with peak plasma concentrations in 30–120 minutes (median ~60 minutes).
- Bioavailability: Approximately 15% (oral tablet).
- Metabolism: Extensively metabolised in the liver (CYP3A4, minor CYP3A5/CYP2C isoforms).
- Elimination: Mainly excreted as metabolites in faeces and urine.
- Duration of Effect: Effects typically last 4–5 hours, but may persist longer in some individuals.
- Half-life: Approx. 4–5 hours.
Use in Everyday Life & Best Practices (Australian Context)
Levitra is usually taken “as needed” before planned sexual activity. The usual starting dose for most adults is 10 mg, taken about 25–60 minutes before sexual intercourse. Depending on response and tolerability, your doctor may adjust the dose to 5 mg (lowered) or up to 20 mg (maximum recommended single dose).
- Take no more than once daily. Leave at least 24 hours between doses.
- Sexual stimulation is required for efficacy.
- Do not exceed the prescribed dose.
- Tablets can be taken with a glass of water. Orodispersible tablets dissolve on the tongue without need for water—convenient for discrete use.
- Follow instructions from your Australian GP or pharmacist regarding dose and timing.
Dosing in the Morning vs Evening
Morning Dosing: Uncommonly chosen as peak effects may not coincide with planned sexual activity; the drug does not create spontaneous erections.
Evening Dosing: Most patients in Australia prefer to take Levitra in the evening before anticipated sexual activity. There is flexibility as the effect window (up to 5 hours) suits most couple’s lifestyles.
Tips: Time the dose to best match your individual and partner’s preferences. Maintain a consistent pattern to help remember dosing, if used regularly.
Taking With Food or on an Empty Stomach: Dietary Considerations
- With Food: Taking Levitra with a normal meal (e.g., lean meat and vegetables) has little effect on absorption by most Australians. However, a high-fat meal (such as fish and chips or a steak and chips) may delay absorption and onset of action.
- On an Empty Stomach: Often recommended, as it allows for a more rapid onset. Consider taking 30–60 minutes before a meal or 2 hours after eating for best effect.
- Light meals (like toast or cereal) at breakfast are generally fine, but large, fatty, or heavy meals in the evening may delay onset.

Guidelines for Proper Use (Australian Conditions)
- Keep tablets in original packaging below 25°C; avoid direct sunlight and moisture.
- Store out of reach of children and pets.
- Do not share your tablets with others—prescriptions are individualised.
- If you miss a planned dose, use only before intended activity—do not double dose.
- Do not drive or operate machinery if you feel dizzy or have visual changes.
- Contact your GP or pharmacist if you have any persistent adverse effects.
- Dispose of unused medication at your pharmacy via the RUM (Return Unwanted Medicines) project.
Alternative Treatment Options
- Sildenafil (Viagra, generic): Well-known, similar efficacy, onset 30–60 min, duration up to 4 hrs. Sometimes slightly more dietary interaction, possibly more affordable.
- Tadalafil (Cialis, generic): Longer duration (up to 36 hrs), may be taken daily or as needed. Suitable for more spontaneity, but may have more muscle aches as side effect.
- Avanafil (not widely available in Australia): Rapid onset, similar mechanism and safety profile.
- Non-pharmacological treatments: Psychological counselling, vacuum erection devices, penile implants (for selected cases and after failure of medical therapy).
Legal, Registration & Reimbursement Status (Australia)
- Levitra is registered by the Therapeutic Goods Administration (TGA).
- Available as a Schedule 4 (S4) Prescription Only Medicine.

Latest Research & Clinical Guidance (2022–2025)
- The 2023 RACGP Guidelines for Men’s Health continue to recommend PDE5 inhibitors (including vardenafil) as first-line therapy for erectile dysfunction in Australia.
- Recent meta-analyses (European Urology 2023; British Journal of Urology International 2024) show similar efficacy among all oral PDE5 inhibitors; patient tolerance and preference are important when choosing an agent.
- Studies confirm that vardenafil offers a favourable safety profile for most Australian men, including those with stable cardiovascular disease where not contraindicated (Curr Opin Urol 2024).
- Current research explores low-dose daily regimens, but in Australia these are not routinely recommended or registered.

Frequently Asked Questions (FAQ)
- Is Levitra suitable for all men with erectile dysfunction?
Levitra is suitable for most adult men with ED, but should not be used by those taking nitrates, some heart medications, or with certain medical conditions. Your GP or pharmacist will assess if it is right for you. - Can I use Levitra with alcohol?
It is safest to limit alcohol while using Levitra, as both can lower blood pressure and increase risk of dizziness, headache, or fainting. - Can I take Levitra every day?
No—Levitra is recommended as needed, not for daily use. Never take more than one dose in 24 hours. - Is there a difference between “Levitra” and “generic vardenafil”?
No. All forms of vardenafil (including generics) have the same active ingredient and are regulated by the TGA for quality and safety. - What should I do if I experience side effects?
Mild side effects (e.g., headache, flushing) are usually temporary. If you have severe symptoms such as chest pain, loss of vision/hearing, or a prolonged erection (>4 hours), seek emergency medical attention immediately.
