Viagra (Sildenafil Citrate) is a prescription drug that’s approved to treat erectile dysfunction (ED). Viagra works by increasing blood flow to your penis, which helps you get and maintain an erection. A study in Singapore shows that 51.3% of men aged 30 years and above in Singapore had some form of erectile dysfunction.

There can be physical causes such as heart disease, high cholesterol, high blood pressure or even obesity. Conversely, there can also be mental causes such as depression, anxiety and stress.

You may be keen to use sildenafil or other drugs as an instant fix. We encourage you to consult a doctor first as this allows the doctor to do a detailed history of your medical and sexual history. This allows him or her to decide if the symptoms are indeed that of erectile dysfunction, and allows for better shared discussion of a safe and targeted treatment plan for you.

Following, your doctor may discuss these (but not limited to):

• Your needs
• Your expectations
• Treatment safety & options

You are able to obtain Viagra through a prescription from a doctor in Singapore.

If you have specific needs or are not a suitable candidate for sildenafil, your doctor may also advise the following (but not limited to):

• Lifestyle modifications
• Other drug alternatives such as cialis (tadalafil)
• Vacuum Erection Device (VED)
• Injections
• Topical applications
• Referral to a relevant specialist

All of the above have their various trade-offs and should be considered in relation to your own medical history and condition. It is important to treat a medical condition at the root cause(s) where possible.

Do speak to a doctor if you suspect you have erectile dysfunction.

Viagra can be purchased from a clinic or with a doctor's prescription. You will need to consult a doctor through telemedicine or at a clinic physically.
