Eriacta is a prescription medication that contains the active ingredient sildenafil. It is formulated as a pill and is available in a 100 mg strength. Sildenafil belongs to the therapeutic class of erectile dysfunction (ED) treatments. In Hong Kong, Eriacta is classified as a prescription-only medicine and must be dispensed by a licensed pharmacist following a healthcare provider’s order.
Sildenafil is a selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5). By blocking PDE5, sildenafil prevents the breakdown of cyclic guanosine monophosphate (cG → cGMP), a messenger molecule that relaxes smooth muscle in the penile arteries. This relaxation allows increased blood flow into the corpora cavernosa during sexual stimulation, facilitating the development and maintenance of an erection.
Eriacta is approved by health authorities for the treatment of erectile dysfunction in adult men. The medication is intended for use when sexual stimulation occurs; it does not cause an erection without such stimulation.
Sildenafil is also approved under the brand name Revatio for pulmonary arterial hypertension, but Eriacta is not approved for this or any other off-label indications. Use of sildenafil for conditions outside its approved label should only occur under strict medical supervision, with a clear risk-benefit assessment.

Moderate alcohol consumption is generally safe, but excess intake can increase the risk of hypotension and may diminish the drug’s effectiveness. It is advisable to limit alcohol and avoid heavy drinking on the day of use.
Sildenafil has an elimination half-life of about 4 hours, so the majority of the dose is cleared within 24 hours. Detectable levels may persist longer in individuals with severe renal impairment.

High cholesterol alone is not a contraindication. However, uncontrolled cardiovascular disease should be assessed by a healthcare provider before initiating therapy.
The 100 mg Eriacta tablet is typically round, blue-colored, and may bear a distinctive imprint code that identifies the brand and strength. Verify the imprint with the pharmacy packaging.
