Hong Kong's No. 1 online men's health clinic, featuring prescriptions from Hong Kong-registered Western medical doctors and offering clinically proven treatment plans. Safe, confidential, and professional.














PDE5 inhibitors (such as sildenafil and tadalafil) have been clinically validated over decades and are recognized by the global medical community as safe and effective treatments for ED. However, all prescription medications must be used under a doctor’s supervision, and our doctors will assess whether they are appropriate for you based on your health condition.
Each medication has its own unique features: Spedra takes effect the fastest (15 minutes), making it ideal for those seeking immediate results; Cialis lasts the longest (36 hours), making it ideal for those who don’t want to be constrained by time; and sildenafil offers the best value for money, making it ideal for users on a budget. Our doctors will recommend the most suitable option based on your specific needs.
Common mild side effects include headaches, facial flushing, nasal congestion, and indigestion, which usually resolve on their own within a few hours. Serious side effects are very rare. If you are taking nitrate medications (such as nitroglycerin), you should not use PDE5 inhibitors.
Most ED medications are taken as needed, meaning they are taken before sexual activity. However, Cialis (tadalafil) can also be taken daily in a low dose (2.5 mg–5 mg), allowing you to be ready whenever the moment arises, without the need for advance planning.
At EDD Health, all you need to do is complete a simple online consultation, and our Hong Kong-registered doctors will assess your health and issue a prescription. Your medication will be delivered to your specified address in discreet packaging. The entire process is safe, confidential, and convenient.
Moderate alcohol consumption generally does not affect the effectiveness of ED medications, but excessive drinking may reduce their effectiveness and increase the risk of side effects. We recommend limiting your alcohol intake while taking these medications. Please consult our doctors for specific recommendations.
