Assurans is a prescription medication marketed in Hong Kong for the treatment of erectile dysfunction (ED). Its active ingredient is sildenafil, a phosphodiesterase-5 (PDE5) inhibitor that helps increase blood flow to the penis during sexual stimulation. Assurans is supplied as a 20 mg oral pill and is regulated by the Pharmacy and Poisons Board of Hong Kong as a prescription-only product.
Sildenafil blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cG + ). By inhibiting PDE5, sildenafil allows cG + to accumulate within the smooth muscle cells of the penile arteries. Elevated cG + leads to relaxation of these muscles, dilation of the blood vessels, and increased blood flow to the corpora cavernosa. The result is an erection sufficient for sexual activity when sexual arousal is present.
Assurans is approved in Hong Kong for the management of erectile dysfunction in adult males. The medication is intended for use only when sexual stimulation occurs; it does not produce an erection without this trigger.
If any of the above conditions apply, discuss them with a healthcare professional before starting Assurans.
These effects are generally mild and do not require medical attention unless they persist.
Because interaction data for specific brands are limited, patients should always provide their full medication list to the prescribing clinician.
Regular follow-up with a healthcare provider is recommended to assess treatment effectiveness, tolerability, and any potential cardiovascular concerns. Routine laboratory tests are not required for most patients, but blood pressure monitoring is advisable, especially in those with known cardiovascular disease.

Treatment decisions, including use for unapproved indications, must be made under the guidance of a qualified healthcare provider.

Moderate alcohol intake generally does not interfere with the effectiveness of Assurans, but excessive drinking can increase the likelihood of dizziness, headache, and low blood pressure. If you plan to consume large amounts of alcohol, discuss it with your prescriber.
The pharmacologic effect of sildenafil typically lasts 4 to 6 hours, although the ability to achieve an erection depends on sexual stimulation during that window.
A high-fat meal may delay the onset of action by up to two hours, but it does not reduce overall effectiveness. Taking the pill on an empty stomach or after a light meal can provide faster results.
A prolonged erection (priapism) is a medical emergency. Seek immediate care at an emergency department; prompt treatment reduces the risk of permanent tissue damage.
Age alone is not a contraindication. Older men may be more sensitive to blood-pressure effects, so a cautious start at the lowest dose (20 mg) and close monitoring are recommended.
Most antihypertensive drugs are safe to combine with sildenafil, but certain agents-especially nitrates-can cause dangerous drops in blood pressure. Always inform your doctor of all cardiovascular medications you are taking.
Sildenafil does not affect sperm production or fertility. It works locally in penile tissue and does not interfere with reproductive hormones.
Yes, you may carry Assurans in your carry-on bag for personal use, provided the medication is in its original labeled container and you have a copy of the prescription or a doctor’s note if requested by customs officials.
All sildenafil products contain the same active ingredient and work via the same mechanism. Minor variations may exist in inactive ingredients or tablet appearance, but therapeutic outcomes are expected to be equivalent when the same dose is used.
Do not flush tablets down the toilet. Follow local pharmacy guidelines for medication take-back programs, or mix the pills with an unpalatable substance (e.g., coffee grounds) before discarding them in the household trash.
