What is erectile dysfunction (ED)?
What are the symptoms of erectile dysfunction? ED is when a man is unable to get an erection or maintain it, making penetrative sex difficult or impossible. It can affect relationships and confidence, but ED is treatable.
What causes erectile dysfunction?
ED can have both physical and psychological causes. In most cases it is due to a reduced blood flow to the penis. Anxiety, stress and depression can also cause erectile problems.
Treatments & possible side effects
Treatment works in 50-80% of cases, increasing blood flow to the penis and enabling an erection when aroused. Side effects vary, but may include nausea, back pain or indigestion.

ED affects most men at some point in their life. You may experience it only once, or it may be a regular issue. It can be a part of ageing, though men can experience it from the age of 18. While it can be embarrassing, it’s common and treatable.
Why are health checks important when you have ED?
ED can often be a symptom of health conditions that affect your blood vessels and heart: high blood pressure, diabetes or high cholesterol. We advise you to have health check to ensure your ED is not being caused by an underlying health condition.
Strength and dosage (mg) for ED medication
The higher the dosage of the tablet, the stronger the effect of the treatment. It won’t work faster, or for longer. Any side effects you experience will be stronger as well. We usually advise you choose a lower dose if it’s your first time taking that treatment.
Are there any alternative treatments for erectile dysfunction?
Counselling can help if stress or anxiety are causing your ED. Devices like vacuum pumps or constriction rings can also be highly effective. Non-prescription remedies and pills for sale online tend to be unregulated – for your safety, we advise to avoid these.
