Fildena XXX is a brand-name medication that contains sildenafil as its sole active ingredient. Sildenafil belongs to the class of phosphodiesterase-5 (PDE5) inhibitors and is used to treat erectile dysfunction (ED). In Hong Kong, sildenafil-containing products are prescription-only medicines and are regulated by the Department of Health. Fildena XXX is supplied as a 100 mg oral pill.
Sildenafil blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cG → cGMP) in the smooth muscle of the penis. By inhibiting PDE5, sildenafil increases cGMP levels, allowing blood vessels to relax and blood flow to the corpus cavernosum to rise during sexual stimulation. The result is an erection that can be maintained for the duration of sexual activity.
Sildenafil is absorbed rapidly from the gastrointestinal tract, with an oral bioavailability of about 40 % under fasting conditions. Food, especially a high-fat meal, can delay absorption and slightly reduce peak concentrations, but the overall effectiveness remains.
In Hong Kong, the approved indication for sildenafil-containing tablets is the treatment of erectile dysfunction in adult males. The medication is intended for men who have difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.
Sildenafil is also approved in many jurisdictions for the treatment of pulmonary arterial hypertension (PAH) under the brand name Revatio. While Fildena XXX is marketed for ED, the same active ingredient has demonstrated benefit in lowering pulmonary arterial pressure.
Disclaimer: Use of Fildena XXX for pulmonary hypertension is off-label and should only be considered under the direct supervision of a specialist familiar with the risks and dosing adjustments required for that condition.

Sildenafil is not a prohibited substance in standard workplace or athletic drug screenings. However, some sports organizations list PDE5 inhibitors as “restricted” for specific competitive categories; consult the relevant authority if you are a professional athlete.
In Hong Kong, sildenafil tablets are prescription-only medicines. Purchasing them from unregulated online sources carries risks of counterfeit products and legal penalties. Always obtain the medication through a licensed pharmacy with a valid prescription.
Both drugs belong to the PDE5 inhibitor class, but sildenafil generally has a shorter duration (≈4 hours) compared with tadalafil’s up-to-36-hour window. The choice depends on personal preference, dosing convenience, and individual response.
Sildenafil can be used safely in men with well-controlled hypertension. However, it should be avoided in severe uncontrolled cases or when combined with nitrate therapy. Discuss blood-pressure management with your clinician before starting.
Treat this as a medical emergency. Seek immediate attention at an emergency department; prompt treatment can prevent permanent tissue damage.
Yes. A high-fat meal can delay absorption, postponing the onset of action by up to two hours. For the most reliable timing, take the tablet on an empty stomach or with a light meal.
Sildenafil is available as a generic medication in many markets, often labeled simply as “sildenafil 100 mg tablets.” Generic versions contain the same active ingredient and are therapeutically equivalent when sourced from reputable manufacturers.
When kept at room temperature, away from moisture and light, the tablets remain stable until the expiration date indicated on the package-typically 24-36 months from the manufacturing date.
