Mechanism of Action
For Patients: Levitra Soft (Vardenafil) helps men with erectile dysfunction (ED) achieve and maintain an erection that is sufficient for sexual activity. It works by increasing blood flow to the penis during sexual stimulation.
For Healthcare Professionals: Vardenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. Inhibition of PDE5 enhances nitric oxide–mediated vasodilation in the corpus cavernosum, resulting in increased cyclic guanosine monophosphate (cGMP) concentrations and smooth muscle relaxation, thus facilitating erectile function during sexual arousal.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration. Tmax (peak plasma concentration): usually within 30–120 minutes; quicker onset with soft formulations.
- Bioavailability: Approx. 15% (higher with soft/chewable tablets due to sublingual/buccal absorption)
- Metabolism: Primarily hepatic via CYP3A4 (major), CYP3A5, and CYP2C9 (minor)
- Elimination: Excreted mainly in faeces (91–95%), ~2–3% in urine. Terminal half-life: 4–5 hours
- Duration of action: Up to 4–6 hours post-dose
Use in Everyday Life and Best Practices
- Typical starting dose: 10 mg taken about 25–60 minutes before sexual activity
- Soft tablet mode: Chewed or allowed to dissolve under the tongue without water, for discreet and convenient use; can be taken with or without food
- Not for continuous daily use: Should not be taken more than once daily
- Dose adjustment: May be increased to 20 mg or decreased to 5 mg based on efficacy and tolerability
- For men only: Not suitable for women or children
- Discuss with your GP or pharmacist: If you have cardiovascular disease, severe hepatic impairment, or are taking other medications
Dosing in the Morning vs Evening
- Evening use: Most common, as it aligns with typical times of sexual activity; allows for planning
- Morning use: Possible if sexual activity is planned for earlier in the day. Be aware that absorption may vary depending on recent meals and level of alertness
- Tips for regularity: Not required daily. Take only as needed, but at approximately the same timing relative to intended sexual activity (e.g., always 30–60 minutes prior)
- Advice: Avoid simultaneous use with heavy meals or large amounts of alcohol, as this may delay or reduce efficacy
Taking with Food or on an Empty Stomach
Levitra Soft can be taken with or without food. However, high-fat or heavy meals (such as traditional Australian barbecue, fatty seafood, or takeaways) may delay its onset of action. For maximum effect, avoid large or high-fat meals directly before taking your dose. Lighter meals, low in fat, such as grilled fish, salad, or breakfast cereals, are unlikely to impact the medicine’s absorption. Taking the medication on an empty stomach may provide faster results.
Interaction Warnings
| Category | Interaction | Advice |
|---|---|---|
| Food | High-fat meals | May delay onset and reduce effectiveness; light meals are preferred |
| Alcohol | Excessive alcohol | May increase risk of side effects (dizziness, low blood pressure); limit to 1–2 standard drinks |
| Other Medicines | Nitrates (GTN spray, patches, tablets) | Contraindicated — may cause severe hypotension |
| Other Medicines | CYP3A4 inhibitors (e.g. ketoconazole, ritonavir) | May increase Vardenafil levels and risk of side effects; consult your GP |
| Other Medicines | Alpha-blockers (e.g. prazosin, tamsulosin) | Monitor for low blood pressure, take medications at different times |
| Other Medicines | Antiarrhythmics (e.g. amiodarone, quinidine) | CAUTION – possible additive cardiac risk; specialist advice needed |

Guidelines for Proper Use (Australian Context)
- Take only one dose in a 24-hour period—never exceed the prescribed dose.
- Engage in sexual stimulation for the medication to work effectively—it does not boost libido.
- Consult your pharmacist or doctor before using if you take regular heart or blood pressure medications.
- Keep tablets in the original packaging, out of reach of children, and below 30°C (Australian climate varies—do not store in cars or bathrooms).
- Do not drive or operate machinery immediately after taking if you feel dizzy or lightheaded.
- Maintain regular check-ups (at least annually) to review ongoing need and cardiovascular health, as recommended by Australian clinical guidelines.

| Viagra | Sildenafil | Yes | Well-known; slightly lower cost; longer safety history | Delayed onset with food; headache, flushing |
| Cialis | Tadalafil | Yes | Longer action (up to 36 hrs); daily low-dose option | Longer systemic exposure; cost; more muscle pain |
| Spedra | Avanafil | Yes | Fastest onset; few food interactions | Newer, less long-term data |
| Alprostadil | Alprostadil | Yes | Alternative for men who cannot take PDE5 inhibitors | Invasive route (injection or urethral); local side effects |

Latest Research and Clinical Guidance (2022–2025)
- Current Australian and international guidelines (2022–2025) confirm the efficacy and safety of Vardenafil as a first-line oral therapy for erectile dysfunction (see: Australian Therapeutic Guidelines).
- Recent systematic reviews (BMJ, 2023; Lancet, 2024) continue to support comparable efficacy of Vardenafil, Tadalafil, and Sildenafil, with individual choice based on patient preference, speed, and side effect profile.
- Research into broader uses (e.g., pulmonary hypertension, premature ejaculation) remains investigational—Vardenafil is not registered for these indications in Australia.

Frequently Asked Questions (FAQ)
- Q: How quickly does Levitra Soft work?
A: The soft tablet form is absorbed rapidly, often within 15–30 minutes, with peak effect usually seen by 60 minutes. Planning sexual activity for 30–60 minutes after taking is ideal. - Q: Can I take Levitra Soft after eating?
A: Yes, but avoid high-fat or heavy meals shortly before use, as these may slow absorption and reduce effect. Light meals are acceptable. - Q: Is it safe to combine Levitra Soft with other ED medications?
A: No, only one PDE5 inhibitor should be used at a time due to increased risk of side effects. Seek GP advice if current medication is not effective. - Q: Can I use Levitra Soft with alcohol?
A: Moderate alcohol consumption (up to 1–2 standard drinks) is unlikely to interfere, but excessive drinking increases risk of dizziness and low blood pressure. - Q: Will Levitra Soft affect my fertility or testosterone?
A: No—Levitra Soft facilitates erections but does not affect hormone levels or fertility.
