  • Key Information
    Viagra was the first PDE-5 inhibitor licensed to treat erectile dysfunction. The active ingredient is Sildenafil. Viagra is the brand name but you can also buy non-branded sildenafil from The Doctor Service too, which is cheaper.
  • How it works
    It works by blocking the action of a chemical called phosophodiesterase-5 which helps to widen blood vessels flowing to the penis to increase the blood flow helping to maintain an erection.
  • How To Take Viagra
    Viagra should be taken with water about 30-60 minutes before sex. Having a large meal can slow down the absorption time, so taking longer for it work, and sometimes reducing its effectiveness.
  • Effectiveness
    Most men will achieve significant results with PDE-5 inhibitors such as Sildenafil. Some people will get better results at higher doses, whereas others may need to reduce the dose to 25mg if they are unable to tolerate some of the common side effects.
  • When To Take
    The medication is most effective taken 30-60 minutes before sex. Having a large meal may slow down the absorption so it could take more time to have an effect. Its effects usually last up to 4 hours.
  • Different Options
    There are different options apart from Viagra, which might be better suited. See the comparison of different options within the main text.
  • Very common side effects (more than 1 in 10)
    Headache usually mild and self-resolving. If not tolerated you should not take this medication.
  • Common side effects (less than 1 in 10)

Who's getting ED?
60% of Men
by 60 years have experienced ED. Stress and Anxiety are the commonest causes of ED in men under 40, yet less than 50% of us do anything about it. 
Wonder Pills.
It might feel like it. But seriously, Science. They work by opening the blood vessel to the penis, increasing blood flow helping you to Stay Hard.
This is the unbranded version of viagra, so much cheaper despite having the same ingredients. 
It works for 4-6 hours and takes 30-60 minutes to take effect. If you're not sure which to take this is usually a great start. 


Lasts up to 36 hours
on just one tablet, and takes around 60 minutes to take full effect. 

The quickest to start working, in just 15-30 minutes, and still lasts up to 4 hours. 

Alternative Treatments 
There are other similar tablets, but we're keeping it simple. There's no need to pay more for more expensive options that are exactly the same medication, or don't provide clearer benefits for the price paid. 

Sildenafil treatments come under brand names such as Silagra, Kamagra, Edegra, Penegra, Zenegra and Manly, cobra, eriacta and superblue! We just call it one name. Sildenafil. And we know it's the real deal. Sometimes peeople refer to it also a generic viagra. Whereas Tadalafil sometimes referred to as the 'weekender' due to it lasting up to 36 hours, and is also known as adcirca and tadacip. 

Psychosexual therapy 
can help if mental health problems are thought to be the cause. Suppositories placed within the penis may stimulate an erection or injecting medication into the base of the penis, or using Vacuum devices.
Key Information
What Causes ED? 
Reduced blood flow to the penis prevents strong erections. This the most commonest cause in men aged over 40. The reduced blood flow occurs becuase of reduced quality of the vessel.

Age is a factor, but our unhealthy lifestyles, lack of exercise, smoking and alcohol all contribute. Other conditions may contribute to this including diabetes, cardiovascular disease or physical injuries. 

In men aged under 40, stress related causes are the most common, as the body isn't able to release the hormones to enable the blood vessel to stay open. Parkinsons, multiple sclerosis or a stroke, previous surgery, e.g. to the prostate gland may also contribute to ED. 

Healthy Living 
Good blood flow to the penis is maintained by living a healthy diet and lifestyle. Avoid smoking and reduce alcohol intake if you drink large amounts. If you are diabetic you should make sure this is managed well. 

If you're experiencing erectile dysfunction for the first time it would be useful to get advice from a health professional if you've not done so already. It may be useful to check your cardiovascular risk and for diabetes. Other services won't tell you this.
