Erectile dysfunction is when men are unable to get or keep an erection suitable for sex. Dr Fox provides advice and confidential treatment for erectile dysfunction posted direct.
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.
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:
- Viagra tablets (25mg, 50mg, 100mg)
- Viagra Connect tablets (50mg only)
- Sildenafil tablets: low cost generic Viagra (25mg, 50mg, 100mg)
- Cialis tablets (2.5mg, 5mg, 10mg, 20mg)
- Tadalafil tablets: low cost generic Cialis (2.5mg, 5mg, 10mg, 20mg)
- Levitra tablets (5mg, 10mg, 20mg)
- Levitra orodispersible tablets (10mg)
- Vardenafil tablets (5mg, 10mg, 20mg)
- Spedra tablets (50mg, 100mg, 200mg)
Each tablet has a different duration of action and side effects – see tablet differences below.
No combination of Viagra/sildenafil, Cialis/tadalafil, Levitra/vardenafil, 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.
Lifestyle and risk factors
Improving lifestyle factors such as diet, exercise, smoking, excessive alcohol, and maintaining an active lifestyle has shown improvement in ED in men of all ages. Apart from the general benefits of a healthy lifestyle, studies show improvement in erectile dysfunction symptoms and a reduced need for tablets. ED also shares risk factors with a range of other medical conditions including diabetes, heart disease, and circulatory problems, all of which are also likely to benefit from lifestyle modification.
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 £6.90.
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
