Both medications contain the same active ingredient and have the same effects. The main difference is that Ernafil is a generic drug that uses the same active ingredient as the brand-name medication, while Viagra is a brand-name drug developed and manufactured by the original manufacturer. Both medications help increase blood flow to the penis in response to sexual stimulation, thereby improving erectile dysfunction.

Sildenafil is a prescription drug in Hong Kong. It can be purchased through legal channels (including registered pharmacies or legitimate online healthcare platforms) after consulting a locally registered Western-trained physician and obtaining a prescription, ensuring that the medication is taken safely under a doctor’s guidance and comes from a reliable source.

The medication usually begins to take effect within about 30 to 60 minutes after taking it, but the exact time may vary depending on factors such as individual constitution and diet. High-fat foods or alcohol may slow the body’s absorption of the medication; it is recommended to take it on an empty stomach for best results.
