What is Erectile Dysfunction?

Erectile Dysfunction is defined as difficulty in getting and/or maintaining an erection satisfactory for sexual performance. There are many short-lived problems which will lead to men occasionally having difficulty getting an erection, however, erectile dysfunction is a term used when this is a recurring or persistent issue. 

While this is more prevalent in older men, this is something which can happen to men of any age and varies in severity. Studies have shown that approximately 40% of men are affected at age 40 and nearly 70% of men are affected at age 70. This widespread presence within the community highlights why it is so important to lose the taboo around this topic and open it up for discussion. It is normally a problem which men can self-diagnose and can now conveniently self-treat.

What Is Sidena?

Sidena is a tablet to treat erectile dysfucntion in men containing Sildenafil. It is the first generic Sildenafil tablet available over the counter in Ireland without a prescription. A generic medicine is one that is similar to an originator medicine which has come off patent. In this case, Sidena is a genric equivalent of Viagra.

Hints and tips when taking Sidena Sildenafil tablets

  • Take with or without food. However, consuming a fatty meal at the same time as this medication can result in it taking longer to work.
  • Do not drink too much alcohol when taking Sidena as it may increase side effects experienced. Alcohol can also make it more difficult to obtain and maintain an erection. 
  • Do not drink grapefruit juice when taking Sidena, it may affect how the medication works.
