Important Medical Information

What is erectile dysfunction?

Erectile dysfunction (ED) is when it is difficult for a man to get or keep an erection firm enough for penetrative sex.It is a common problem and happens to most men from time to time, especially if they are feeling tired, stressed or have consumed too much alcohol.

For some men, it can become a recurring or persistent problem. This can happen at any age but is more common with increasing age due to many different physical causes. It can lead to stress and have a negative effect on your self-confidence and relationships. This in turn can worsen ED symptoms.

Approximately half of all men between 40 and 70 years have experienced ED.

ED is not the same as premature ejaculation (when ejaculation occurs less than 2 minutes after penetration). If this is more in keeping with your symptoms, please use our premature ejaculation service.

What causes erectile dysfunction?

Erectile dysfunction (ED) can occur at any age, but is more common as you get older. There are physical and psychological causes of ED. The cause can be related to a combination of these factors listed below.

The main physical cause of ED is the narrowing of the blood vessels supplying the penis. This prevents adequate blood flow to this area to get or maintain an erection. Diabetes, high blood pressure and high cholesterol are all causes of ED as they cause narrowing of the blood vessels. These are by far the most common causes of ED in men over 40 years of age.

ED can be an early warning sign of these conditions, and others such as heart disease, which is why men are advised to have a physical check-up with some routine blood tests.

Other physical causes of ED include:

  • Obesity.
  • Hormonal abnormalities.
  • Smoking, alcohol and drug use (especially with long-term or heavy use).
  • Some Medications (e.g. steroids, including anabolic steroids).
  • Nerve damage (Such as can occur in Multiple Sclerosis).

In most cases that are due to a physical cause, the symptoms develop gradually and you may have intermittent symptoms for a while before they become more persistent. Your libido (sex drive) is likely to be normal if the cause is not related to hormones or psychological reasons

Psychological causes include:

  • Stress.
  • Anxiety (including performance anxiety).
  • Depression.
  • Relationship problems can also play a role.

If the cause is due to psychological factors, the symptoms will often develop suddenly. They may improve spontaneously as your psychological state improves.

Medications can help you to achieve and maintain an erection. However, ED medications will not treat any underlying medical conditions that are causing or contributing to this problem. We strongly advise that you consult with a doctor for advice on assessment and management of any underlying cause. This is a good opportunity to review your general health, including cardiovascular risk factors.

Are there medications that can interact with prescription ED treatments?
There are some drugs that should not be taken together because of potential adverse interactions, making the risks outweigh the potential benefits.
It is VERY important that you let us know exactly what medications you are taking so that we can safely prescribe a treatment for you.
What treatments are available via this service?
We can provide a range of erectile dysfunction medications, both branded and generic, subject to clinical suitability.

A 6-month prescription for up to 16 tablets per month will be issued. These medications should be used as per the instructions on the prescription. Do not take more than the recommended dose.

How do these medications work?

These medications work by relaxing the blood vessels in the penis, allowing increased blood flow to help you to get and maintain an erection when you are aroused. (You will need to have sexual stimulation to help with this medication).

They all belong to the same group of medications but have a different active ingredient. There is a slight variation on how each tablet works, and they each have individual time frames for the onset of action and duration of action.

You may need to vary the timing and the dose, or type of medication to get the best individual result.

Your medication may not work the first time you try it, and you may need to take it on 4 to 6 separate occasions to assess the full effect. If it has not helped after this, you can contact us for advice.

What are the potential side effects of these medications?

These medications are usually tolerated very well.
You are less likely to experience side effects with lower doses of medications, and we recommend that you try the standard dose first – this can be adjusted depending on your response to the treatment and side effects if they should occur.

If side effects occur, they can include:

  • Headaches.
  • Dizziness.
  • Flushing.
  • Stuffy nose.
  • Stomach upset/and indigestion.
  • Visual disturbance can occur, such as blurred vision, increased sensitivity to light and a blue/halo around bright light.

For full details of the potential side effects of these medications, please ensure that you read the patient information leaflet that comes with your medication before you start to use it for full details on potential side effects.

If you are concerned that you are developing side effects, we advise that you stop your medication and seek medical advice.

Are there things I can do to help erectile dysfunction symptoms?


There are lots of lifestyle changes you can make to help improve your symptoms:

  • Drinking alcohol within the recommended limits (< 17 units per week).

  • Stop smoking (smoking causes narrowing of all blood vessels in the body).

  • Maintain a healthy weight: ED is more common if you are overweight or obese and losing weight has been shown to help.

  • Regular exercise.

  • Manage stress (sometimes easier said than done!).

Important safety information

When completing the questionnaire, please ensure you let us know exactly what medications you are taking (prescribed and over-the-counter), herbal remedies or recreational drugs as erectile dysfunction medications can have significant interactions with some drugs. This will enable us to advise you on appropriate treatments and prescribe them safely for you.

Do not take more than one tablet in 24 hours and do not combine it with other erectile dysfunction medications.
