Medical information

Erectile dysfunction (ED) is common. It is not usually caused by low hormone levels. Most men with erectile dysfunction are in reasonable health, although erectile dysfunction may be a symptom of poor circulation or early diabetes. Erectile dysfunction is more common in smokers and men who are overweight. Some medicines including herbal medicines can contribute to ED. Some men with ED have low testosterone levels. Cycling more than 3 hours a day can cause ED.

All men with ED should tell their GPs about it.

ED treatments

Over the last decade medications have revolutionised the treatment of erectile dysfunction. These medications work by enhancing the natural reaction to stimulation, opening up the blood flow needed for erections. Other treatments for ED include topical applications, injections into the penis, surgical devices and counselling.

Types of treatment

Seven different medications are available to buy online from Dr Fox:

Each tablet has a different duration of action and side effects – see tablet differences below.

No combination of Viagra/sildenafil, Cialis/tadalafil, Levitra, Spedra or other ED treatment should be used at the same time – a break of up to 24 hours (36 hours for Cialis/tadalafil) should be left.

Investigating erectile dysfunction

You should always tell your regular doctor if you are having problems with erections.

Erectile dysfunction can be a symptom of conditions such as diabetes, high blood pressure, high cholesterol or narrowing of the arteries. Some simple tests may be required. A face-to-face assessment with a doctor is particularly important if symptoms develop over a period of weeks or months, or even suddenly, without an emotional event to set them off. Erectile dysfunction can be a complication of previous operations or a side effect of some prescribed medication.

Starting treatment

It is best to start with a lower strength tablet and build up as needed (see how to start treatment). One type of tablet sometimes works better than another. You may like to try out different tablets to see which ones suit you best.

Sexual stimulation is required for tablets to work. Without it tablets will have no effect.

You can request more than one type of tablet at a time. A first trial of treatment starts at £8.60.


Erectile dysfunction can be distressing and lead to relationship difficulties, anxiety and depression. Your regular doctor may recommend counselling. This may help resolve the cause of erectile dysfunction. In some cases a problem of performance anxiety can be overcome by breaking the cycle of failure with tablet treatments.

Buy treatment

Dr Fox supplies treatment for erectile dysfunction (impotence) on prescription – you are required to answer a short medical questionnaire before your order can be completed.

Answer medical questions to order(erectile dysfunction)

Men only

Have you read the erectile dysfunction medical information?

Please read the medical information.
See also starting treatment for the first time.

Do you sometimes or always have difficulty getting and keeping an erection?

Have you had difficulties with erections for more than a year?

Are your erections sometimes fine?

E.g. when waking in the morning, during masturbation or in some erotic situations.

Is your blood pressure high (over 150/90)?

You must have had a blood pressure check within the last year and know the result. Doctors, nurses and some pharmacist can check blood pressure. Answer 'Yes' if either figure is high, 150 or 90. A blood pressure measurement whilst taking blood pressure tablets qualifies.

Do you have low blood pressure?

This means any of the following:

  • Low blood pressure requiring investigation
  • Low blood pressure requiring treatment
  • Being prone to faint or feel light-headed for more than a few seconds when standing up quickly or standing for long periods

Are you over weight?

Use this BMI (Body Mass Index) calculator and answer 'yes' if the result is over 30.

Do you smoke or drink more than 21 units of alcohol per week?

Have you been diagnosed with any of the following?

  • Allergy or reaction to previous impotence treatments
  • Heart disease including heart attack within 6 weeks or angina (heart pain on exertion)
  • History of stroke or mini stroke (transient ischaemic attack)
  • History of vision problems due to poor circulation
  • Family history of the degenerative eye disease, including retinitis pigmentosa (rare)
  • Serious kidney/renal or liver disease

  • Sickle cell disease or leukaemia or multiple myeloma
  • A bleeding disorder (such as Haemophilia)
  • Active stomach ulcers (also known as peptic ulcer or gastric ulcer)

Are you taking any of the following?

  • Existing ED treatment apart from Viagra/sildenafil, Cialis/tadalafil, Levitra, or Spedra
  • Nitrates for angina or heart failure, includes glyceryl trinitrate, isosorbide mononitrate, isosorbide dinitrate, GTN spray or gel, or nicorandil - serious reaction possible
  • Ritonavir or Indinavir or medicine for HIV
  • Riociguat for high blood pressure in the lungs
  • Ketoconazole or itraconazole or other anti-fungal medication
  • The any recreational drug amyl nitrate (Poppers) - serious reaction possible
  • Alpha-blockers (sometimes used to treat high blood pressure or prostate enlargement) includes alfuzosin, doxazosin, indoramin, prazosin, tamsulosin, terazosin

Have you been advised to avoid vigorous exercise?

E.g. severe heart failure or unstable angina.

Are you aware if you have a continuous erection for 4 hours or more you should seek immediate medical advice?

This is unlikely to happen and is rare. If it occurs seek medical advice straight away to prevent permanent damage.

Are you aware you should not take any combination of Viagra/sildenafil, Cialis/tadalafil, Levitra or Spedra, or use any other ED treatment, at the same time?

  • A break of up to 24 hours (36 hours for Cialis/tadalafil) should be left.
  • Also do NOT exceed the prescribed dose.

Do all the following apply to you?

  • I will read the patient information leaflet supplied with my tablets
  • I will tell my GP about my erectile dysfunction and my treatment
  • The tablets are for my own use
  • I am over 18
  • I agree to the terms and conditions
