What is ED and how can treatment help?

Erectile dysfunction or impotence commonly known as ED is the inability to get an erection and maintain it for satisfactory intercourse. The brain sends a signal to the penis when a man is sexually stimulated, these signals increase the blood flow which result in a firm erection. Erectile dysfunction treatments can help gain an erection and maintain it to have penetrative sex and enjoy it. ED is not the same as premature ejaculation (PE) which is when a man gets aroused and ejaculates really quickly.

What are the causes of erectile dysfunction?

Erectile dysfunction can be caused by a range of physiological or psychological factors. It can also come about due to some medicine. Psychological causes of erectile dysfunction can stem from stress, anxiety, depression or problems in your relationship. Physical causes of ED on the other hand can vary from conditions related to blood circulation, nervous system, diabetes, high blood pressure or cholesterol, surgery and injuries.

What neurogenic conditions can cause ED?

Neurogenic problems include Parkinson’s disease, a stroke, Multiple Sclerosis or spinal disorders. All these issues involve the spinal cord, the brain and nerves which can result in erectile dysfunction.

Can hormonal conditions cause ED?

Hormonal conditions include an underactive or overactive thyroid or Cushing’s syndrome. These conditions can fluctuate the hormone levels in your body which can result in erectile dysfunction.

What medicines can cause impotence?

There is a range of medicine which can result in ED, for example:
  • Antidepressants
  • Antihistamines used for allergies / hay fever
  • Fibrates used for lowering cholesterol levels
  • Beta-blockers prescribed for high blood pressure treatment
  • Diuretics prescribed for heart failure, kidney problems and high blood pressure
  • Corticosteroids
  • Epilepsy medicine
This list is not exhaustive.

How does Erectile Dysfunction Treatment Work?

ED medicine such as Viagra (sildenafil), Cialis and Levitra all belong to the group of medicine called PDE5 inhibitors. They help in opening up the blood vessels and improving the blood flow to the penis when you are sexually stimulated. This results in achieving and maintaining a firm erection to help you enjoy penetrative sex. ED medicine is statistically effective in 80% of patients.

Can I treat ED with making lifestyle changes?

It is possible to improve erection issues by adopting a healthier and more active lifestyle. Some positive changes include quitting smoking, a regular exercise regime, reduce stress, no drugs and don’t consume too much alcohol. Healthy eating and exercising regularly should help drop your weight and improve your energy levels and ED issue.

What medicine is available in the UK to treat erectile dysfunction / impotence?

There are currently four kinds of PDE-5 inhibitors licensed by the MHRA in the UK, these are:

Viagra: this is the most well-known ED medicine on the market and contains the active ingredient sildenafil.
Generic Viagra: this is identical to Viagra but available at a much lower cost and contains sildenafil.
Levitra: this contains the active ingredient vardenafil and is normally more suitable for diabetics.
Cialis: this is also a well-known branded medicine and contains the active ingredient tadalafil.
Spedra: This is the newest ED medicine available in the UK and contains the active ingredient avanafil.

How long do these treatments last?

Viagra lasts between 4 to 8 hours similar to Levitra. Cialis is a much longer lasting ED medicine – up to 36 hours which is recommended for people needing long term treatment. Spedra is the fastest acting ED medicine out of them all, effective within 15 minutes and can last between 4 to 6 hours.

Can I get treated on the NHS?

You can get all the PDE-5 inhibitors from your GP on prescription but you will be required to pay the full cost of the medicine which can vary depending on your pharmacy buy normally between £20-£30 for 4 tablets. If you suffer from certain conditions you can get the treatment on the NHS, you can discuss these in detail with your GP. Some examples are MS, Parkinson’s disease, some severe injuries, prostate cancer etc.

How to treat impotence due to a core health issue?

If you suffer from impotence due to an underlying health problem, you will need to speak to your GP about treating this issue prior to starting any PDE-5 inhibitors. This will save you from temporarily solving the problem and you might find you do not suffer from ED anymore once the underlying issue causing erectile dysfunction is cleared. If you feel the ED issue has come about due to a specific medication you are one, speak to your doctor to discuss alternative medication or treatment.

Side effects and warnings for Erectile Dysfunction treatments

Men who suffer from heart conditions should take caution to use erectile treatments. You should discuss your treatment options with your doctor if you suffer from coronary heart disease, other cardiovascular conditions and Peyronie’s disease (issues with the penis). Sex is a good form of exercise to improve your heart condition but your GP has to declare you are fit enough for the medication beforehand.

If you are using any substances that contain nitrates, or other medication for angina then avoid taking any PDE-5 as mixing the two can be dangerous.

You should not take any erectile dysfunction treatments without the consent of your doctor if you suffer from low blood pressure, unstable angina, have had a heart attack or stroke lately or been told to not have sex / any activity which widens your blood vessels.
