Valif contains vardenafil as its active component. Vardenafil is a phosphodiesterase-5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) in adult men. The medication is supplied as a 20 mg oral pill and is classified as a prescription-only product (Rx) in Hong Kong, regulated by the Pharmacy and Poisons Board of the Department of Health.
Vardenafil belongs to the PDE5 inhibitor class. By blocking the PDE5 enzyme, it prevents the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle of the penile blood vessels. Elevated cGMP leads to relaxation of smooth muscle, increased blood flow, and an erection in response to sexual stimulation. The drug begins to act within 30 minutes, reaches peak plasma concentrations in about 1 hour, and its effects typically last for up to 4-5 hours. Oral absorption is rapid, with a bioavailability of roughly 15 %, and the drug is metabolized mainly by the hepatic CYP3A4 pathway.
These effects are typically mild and transient. Patients should hydrate and avoid excessive alcohol, which can exacerbate dizziness.

Moderate alcohol consumption may increase the risk of dizziness and hypotension when combined with Valif. It is advisable to limit alcohol intake and to avoid excessive drinking before taking the medication.
A prolonged erection (priapism) requires immediate medical attention to prevent permanent damage. Seek emergency care promptly; do not attempt to treat it yourself.
Some herbal products, such as St. John’s wort, can induce the CYP3A4 enzyme and potentially reduce Valif’s effectiveness. Inform your healthcare provider of all supplements you are taking.

Valif (vardenafil) has a slightly faster onset of action and may have a shorter duration of effect compared with sildenafil. Individual response varies, so the choice of agent should be personalized.
Valif is approved for use on an as-needed basis. A daily dosing regimen is not standard and should only be considered under direct medical supervision.
Rarely, users may experience changes in color vision, blurred vision, or a temporary blue tint. If visual disturbances persist, discontinue the medication and seek medical evaluation.
Men with stable cardiovascular conditions may use Valif, but they must be cleared by a healthcare professional to ensure that sexual activity does not pose undue risk.
Keep the medication in its original container, at room temperature, protected from moisture and heat. Carry it in your carry-on luggage to avoid temperature extremes in checked baggage.
