Vardenafil is an oral medication used to treat erectile dysfunction (ED). It belongs to the phosphodiesterase-5 (PDE-5) inhibitor class and is available in pill form in strengths of 10 mg, 20 mg, 40 mg, and 60 mg. In Hong Kong, Vardenafil is a prescription-only product regulated by the Department of Health under the Pharmacy and Poisons Ordinance.
Vardenafil blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cG → cGMP) in the smooth muscle of the penile arteries. By inhibiting PDE-5, Vardenafil allows cGMP to accumulate, leading to prolonged smooth-muscle relaxation and increased blood flow to the corpus cavernosum during sexual stimulation.
Vardenafil is FDA- and EMA-approved for the treatment of erectile dysfunction in adult males. It is indicated for men who experience difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity. The medication does not cure the underlying causes of ED; it facilitates the physiological response to sexual arousal.
These effects typically resolve without medical intervention. Hydration and avoiding excessive alcohol may lessen their frequency.
If any of these events occur, seek immediate medical attention.
Patients should disclose all prescription medicines, over-the-counter products, herbal supplements, and dietary habits to their prescriber before starting Vardenafil.
Individual dosing must be personalized by a qualified healthcare professional.
Routine laboratory monitoring is not required for most patients on Vardenafil. However, periodic assessment is advisable for individuals with cardiovascular disease or renal/hepatic impairment:
Patients should contact their provider if they experience persistent side effects, unexpected pain, or any of the serious adverse events listed above.

Yes, Vardenafil can be taken with or without food. A high-fat meal may delay the onset of action by about 30 minutes, but the overall effectiveness remains unchanged.
Both drugs inhibit PDE-5, but Vardenafil has a slightly faster onset and may be less affected by food compared with sildenafil. Individual response varies, and the choice of therapy should be guided by the prescriber.
Generally, men with well-controlled blood pressure may use Vardenafil safely, provided they are not taking nitrates. Blood pressure should be monitored when therapy is initiated.
Seek emergency medical care immediately. Priapism is a medical emergency that can cause permanent tissue damage if not treated promptly.
Ginkgo biloba has mild antiplatelet effects and may increase bleeding risk when combined with certain medications, but no direct interaction with Vardenafil has been documented. Nonetheless, disclose all supplements to your healthcare provider.
Vardenafil does not impair cognitive or motor function. However, if you experience dizziness or a sudden drop in blood pressure, avoid driving until the symptoms resolve.
The 60 mg strength is less frequently used and is typically reserved for patients who have not responded to lower doses after careful evaluation. Its prescription should follow an individualized risk-benefit assessment.
Vardenafil should be stopped at least 24 hours before any surgery that may require anesthesia, especially if nitrates or other vasodilators might be used intraoperatively.
Yes, men with diabetes-related erectile dysfunction can be prescribed Vardenafil, but the underlying vascular condition may affect response rates. Monitoring and dose titration may be necessary.
Keep the medication in its original blister pack, at room temperature, and away from direct sunlight. If traveling by air, carry it in your hand luggage to avoid temperature extremes in checked baggage.
