Vilitra (Vardenafil): Patient Information for Australia
Basic Product Information
| International Nonproprietary Name (INN): | Vardenafil |
| Brand Names in Australia: | Levitra®, Vilitra® (imported), Staxyn® (orally disintegrating forms) |
| ATC Code: | G04BE09 |
| Available Forms & Strengths: | Film-coated tablets: 5 mg, 10 mg, 20 mg; Orally disintegrating tablets: 10 mg |
| Manufacturers: | Bayer AG (original); Generic and parallel-imported versions under Vilitra from Sunrise Remedies and other manufacturers |

Mechanism of Action
In simple terms: Vardenafil works by increasing blood flow to the penis, which helps men with erectile dysfunction (ED) to get and maintain an erection when sexually stimulated.
For specialists: Vilitra (Vardenafil) is a selective phosphodiesterase type 5 (PDE5) inhibitor. By inhibiting PDE5, vardenafil prevents the degradation of cGMP in the corpus cavernosum following sexual arousal, resulting in smooth muscle relaxation and increased blood flow.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration, peak plasma concentrations reached in ~0.5 to 1 hour.
- Metabolism: Extensively hepatic, primarily via CYP3A4; minor contributions from CYP3A5 & CYP2C isoenzymes.
- Elimination: Mainly in the faeces (approx. 91–95%), with some renal excretion.
- Duration of Action: Effective for up to 4-6 hours, though some men report erections up to 8 hours post-dose.
Use in Everyday Life and Best Practices
Typical Doses: The recommended starting dose is 10 mg, taken as needed about 25–60 minutes before sexual activity. Dose may be increased to a maximum of 20 mg or decreased to 5 mg based on efficacy and tolerability. Do not take more than one dose per day.
How to Use:
- Take Vilitra with water, as directed by your doctor, before you anticipate sexual activity.
- Avoid using the medicine more often than prescribed.
- Sexual stimulation is required for Vilitra to work.
Dosing in the Morning vs Evening
- Morning use: May suit those planning intimacy earlier in the day; less risk of interaction with heavy evening meals or alcohol.
- Evening use: Most Australians use Vilitra in the evening due to social and familial patterns.
- Regularity: Try to take Vilitra about the same time for each planned episode; avoid unpredictable schedules as best as possible for consistency in response.
- Tip: Allow at least 24 hours between doses to prevent accumulation or side effects.
Taking with Food or on an Empty Stomach
- With food: A standard meal has little impact, but a high-fat meal (e.g., steak, chips, creamy desserts) may delay absorption and effect onset.
- On an empty stomach: Offers the fastest onset (usually within 30–45 minutes).
- Australian dietary tips: If planning a romantic dinner, keep meals light and avoid excess fats or heavy sauces before taking your dose.
Interaction Warnings
| Interaction | Details & Advice |
|---|---|
| Alcohol | Excessive alcohol may worsen side effects (eg, dizziness, low blood pressure) and reduce treatment reliability—moderation recommended. |
| Grapefruit/Grapefruit Juice | May increase vardenafil levels, risk of adverse effects—avoid while taking Vilitra. |
| Nitrates (Nitroglycerin, Isosorbide) | Severe risk of life-threatening hypotension—do NOT use Vilitra with any nitrate-containing medication. |
| Alpha-blockers (eg, doxazosin) | May cause excessive blood pressure drop; seek doctor advice before combined use. |
| Other PDE5 Inhibitors (sildenafil, tadalafil) | Do not combine with Vilitra—no additional benefit, but higher risk of adverse effects. |
| HIV Protease Inhibitors (ritonavir, indinavir) | Can increase vardenafil levels, risk of side effects; dose adjustment or avoidance required. |
| CYP3A4 Inhibitors (e.g., ketoconazole, erythromycin) | May increase vardenafil levels; specialist advice required. |
| Antihypertensive Medications | Monitor for possible additive blood pressure lowering effect, particularly in elderly. |

Guidelines for Proper Use (Australia-specific)
- Always follow doctor’s advice and prescription dispensed by an Australian pharmacist.
- Store Vilitra between 15-30°C in a dry place, away from children and pets.
- Do not purchase from non-pharmacy sources to ensure Australian TGA-regulated quality.
- If you miss a dose, simply wait for the next planned time—Vilitra is not intended for regular, daily use.
- Maintain regular check-ups to assess ongoing suitability and discuss other health concerns (such as blood pressure or diabetes management).
- Dispose of unused medicine at your local pharmacy’s return program for safe disposal.
Alternative Treatment Options
- Sildenafil (Viagra®, Revatio®): Another PDE5 inhibitor, effective for ~4–5 hours. Pros: Well-studied, widely available. Cons: More likely to cause visual disturbances.
- Tadalafil (Cialis®): Longer-acting (up to 36 hrs); also approved for once-daily dosing in benign prostatic hyperplasia. Pros: Flexibility in timing; Cons: Possible muscle aches/back pain.
- Avanafil (not widely available in Australia): Rapid-acting, but cost and local access limited.
- Non-oral therapies: Intracavernosal alprostadil injections, vacuum erection devices. Used if oral medication is contraindicated or ineffective.
- Psychosexual therapy and lifestyle modifications: For patients with psychological contributing factors (refer to specialised counselling services).
Legal, Registration, and Reimbursement Status in Australia
- Vardenafil-containing medicines (Levitra, Vilitra) are listed on the Australian Register of Therapeutic Goods (ARTG).
- Classified as a Prescription Only Medicine (Schedule 4/S4) by the Therapeutic Goods Administration (TGA).
- Not routinely reimbursed by the Pharmaceutical Benefits Scheme (PBS) for erectile dysfunction except in select cases (e.g. prostatectomy, spinal cord injury)—check PBS for details.
- Private scripts available; generic brands may be less expensive than originals.
Latest Research and Clinical Guidance (2022–2025)
- Updated European Association of Urology Guidelines (2023) continue to recommend PDE5 inhibitors, including vardenafil, as first-line therapy for ED (Salonia et al., 2023).
- The 2022 Australian Therapeutic Guidelines: Sexual and Reproductive Health endorse shared decision-making in selecting PDE5 inhibitors based on patient lifestyle and comorbidities.
- Recent studies (Carson et al., 2023; Hatzimouratidis & Shamloul, 2024) confirm the sustained efficacy and safety profile of vardenafil, with no increased cardiovascular risk in properly-selected patients.
- No substantial difference in efficacy between PDE5 inhibitors, but individual tolerability may vary—tailor to patient preference and existing medical history.

Frequently Asked Questions (FAQ)
- Is Vilitra the same as Levitra?
Vilitra contains the same active ingredient, vardenafil, as Levitra. Vilitra is an alternative (often generic or pharmacy-imprinted) version and may be available through some Australian pharmacies, especially via private scripts or online pharmacy networks. - Can I take Vilitra daily?
No. Vilitra is intended for “as needed” use, not daily regular dosing. Take only as prescribed by your doctor, usually before anticipated sexual activity. - Will Vilitra affect my ability to drive?
Most people can drive safely, but if you experience dizziness, sleepiness, or visual changes, wait until these symptoms resolve before driving or operating machinery. - What should I do if I get an erection lasting more than 4 hours?
This is a rare but serious side effect (priapism). Seek immediate medical attention to prevent lasting damage. - Can I use Vilitra with other treatments for ED?
Do not combine Vilitra with other PDE5 inhibitors or ED treatments unless directed by a specialist—there is no added benefit, and side effects may increase.
For further questions, always consult your Australian GP, urologist, or community pharmacist.
