Hong Kong’s No. 1 online men’s health clinic, with prescriptions written by Hong Kong-registered Western medical doctors, offering clinically proven treatment plans. Safe, confidential, and professional.














PDE5 inhibitors (such as sildenafil and tadalafil) have been clinically validated over several decades and are recognized by the global medical community as a safe and effective treatment 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 characteristics: Spedra takes effect the fastest (15 minutes) and is ideal for those seeking immediate results; Cialis lasts the longest (36 hours) and is ideal for those who don’t want to be constrained by time; sildenafil offers the best value for money and is 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), so you’re ready whenever the moment arises, without having to plan ahead.
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 in discreet packaging to your specified address. 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. It is recommended that you limit your alcohol intake while taking these medications. Please consult our doctors for specific recommendations.
