Fildena Strong contains sildenafil as its active component. Sildenafil is a phosphodiesterase-type-5 (PDE5) inhibitor used to treat erectile dysfunction (ED). The medication is supplied as a 120 mg oral pill. In Hong Kong, sildenafil-containing products are prescription-only medicines regulated by the Department of Health under the Pharmacy and Poisons Ordinance. The brand name “Fildena Strong” is one of several market names for sildenafil; other well-known brands include Viagra and Revatio.
Sildenafil blocks the enzyme phosphodiesterase-type-5 found in the smooth muscle of the penis. By inhibiting this enzyme, sildenafil increases levels of cyclic guanosine monophosphate (cG-MP), a messenger that relaxes smooth muscle and allows blood to fill the corpora cavernosa. This physiological response facilitates a penile erection in the presence of sexual stimulation.
Because the mechanism relies on sexual arousal, sildenafil does not cause an erection without it.
Fildena Strong is approved in Hong Kong for the treatment of erectile dysfunction in adult males. It is indicated for men who have difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.
Sildenafil is also approved (under other brand names) for pulmonary arterial hypertension (PAH). While Fildena Strong is marketed for ED, some clinicians may prescribe it off-label for PAH when other formulations are unavailable. Disclaimer: Off-label use of Fildena Strong for PAH is not approved by Hong Kong regulatory authorities and should only be considered under direct medical supervision with a full risk-benefit evaluation.

Sildenafil can be used by patients with controlled hypertension, but it should be prescribed after evaluating cardiovascular risk. Uncontrolled high blood pressure or recent cardiovascular events are contraindications.
Certain herbal products, such as St. John’s wort, affect CYP3A4 enzymes and may alter sildenafil levels. Inform your healthcare provider of all supplements you are taking.
Yes, provided you carry the prescription label and keep the medication in its original packaging. Be aware that some countries have stricter import regulations for PDE5 inhibitors.
The 120 mg strength is higher than the commonly prescribed 50 mg and 100 mg tablets. Because of the higher dose, a prescriber may start at a lower frequency or adjust based on response and tolerability.
A high-fat meal can delay absorption, potentially postponing the onset of action by up to an hour. Taking the pill on an empty stomach usually yields faster results.
Sildenafil is not indicated for use in women, and safety data for female patients are limited. Women seeking treatment for sexual dysfunction should discuss alternative options with a clinician.
Seek emergency medical care immediately. Sudden vision loss may signal a rare but serious adverse event (NAION) that requires prompt evaluation.
Moderate alcohol intake is generally acceptable, but excessive consumption can increase the risk of dizziness and hypotension, potentially reducing the drug’s effectiveness.
Store the tablets in the original container, tightly sealed, until the expiration date. Maintaining room-temperature conditions protects potency.
Sildenafil specifically facilitates penile blood flow; it does not increase libido, sexual desire, or orgasmic function. Psychological and relational factors also influence overall sexual satisfaction.
