What is Erectile Dysfunction?

Erectile dysfunction (ED) is the inability to gain or maintain an erection, sufficient for satisfactory sexual intercourse. It is a very common problem, affecting half of Irish men over 50.


Most men will experience some sort of difficulty in getting an erection over their lives. This difficulty for some men will only be a temporary problem and will often be related back to a specific set of circumstances such as stress, tiredness or even alcohol intake. Erectile Dysfunction is only a problem when it is persistent and recurring. While Erectile Dysfunction is more common in older men, it can occur at any age.

Erectile Dysfunction can also be caused by physical conditions such as Diabetes, uncontrolled High Blood Pressure and Vascular Disease (this is the narrowing of blood vessels) and can be an ‘early warning sign’ of heart disease. Erectile Dysfunction can also be caused by conditions that affect your nerves and hormonal balance. Psychological issues such as stress, depression and anxiety can also contribute to Erectile Dysfunction. In most cases Erectile Dysfunction is caused by a combination of both physical and psychological factors.

Since erectile dysfunction symptoms can vary, some men might want to speak to a healthcare professional before they begin to treat it.  Speak to your GP or a pharmacist if you’re concerned about symptoms.


When is Sidena not suitable?

If you are a woman, a man under the age of 18, or do not have erectile dysfunction, then Sidena isn’t the right treatment for you. Some medicines and health conditions may mean Sidena may not be suitable for you. Our pharmacist will discuss any other medications you may be taking or any health conditions you may suffer from as part of the consultation to determine if Sidena is suitable for you.
