About sildenafil for erectile dysfunction

Erectile dysfunction (sometimes called impotence) means that you cannot get or maintain a proper erection. There are several causes, the most common being due to a narrowing of the arteries that take blood to the penis.

Sildenafil works by preventing the action of a chemical in your body, called phosphodiesterase type-5. This helps to widen (relax) blood vessels and improves the flow of blood to the penis following sexual stimulation. This helps to maintain an erection.

Sildenafil is available on prescription. Non-branded (generic) tablets of sildenafil are available on the NHS, but the brand Viagra® can only be prescribed on the NHS for men with erectile dysfunction resulting from certain medical conditions.

Erectile dysfunction. I have it. Can I hide it?

No. Erectile dysfunction is a serious problem that can affect both the young and the old, involving psychological causes in some cases.

Erectile dysfunction, defined today as the inability to attain and maintain an erect penis with sufficient rigidity for sexual intercourse, has become an increasingly common complaint that affects 140 million men worldwide. Risk factors for developing erectile dysfunction include age, diabetes, hypertension, obesity, lack of exercise, dyslipidemia, smoking, depression, lower urinary tract symptoms, and pelvic surgery.

So, suffering from erectile dysfunction is a serious condition with a markedly negative impact on quality of life.

Sexologists say that most of the underlying causes of impotence involve blood vessels. Smoking, diseases like diabetes, heavy drinking and heart problems can all lead to blood vessel obstruction and therefore impotence, whilst emotional issues can exacerbate the problem.

The good news is that we can handle it.

Can I have Viagra and Sildenafil?

It is the same thing. Sildenafil is the active substance of Viagra, while Viagra is the commercial name. There are also generics of sildenafil available. Teva’s generic Viagra has launched already in December 2017 in the United States. Pfizer recently started to sell the new generic version of Viagra. Not only the generic is cheaper than the original drug but it is also easy to buy over the internet from legitimate UK pharmacy’s. Thus stopping any awkward face to face conversations.

The legend of the blue pill remains but generic alternatives can be used with the same effects, administering the same medicine (sildenafil) but with some extra money in the pockets of the patients.

Does the Viagra dosage I need depend on my age?

Which dosage you need depends on your health and how effective drug is for you rather than your age. Certain age-related conditions may have an impact on the dose you need to take but there is no general advice on which dosage to take at certain ages.

Side effects


Runny or stuffy nose



Difficulty falling or staying asleep

Numbness or tingling in the hands, arms, feet, or legs

Muscle pain or back pain

Sensitivity to light

Vision color changes (seeing blue on objects or being unable to tell the difference between green and blue)

So, how often can I take Sildenafil?

The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity.

You can take one tablet daily if you’re in the mood for love.

Sildenafil usually should not be taken more than once.

You should not take sildenafil every day if you do not intend to have sex every day. Sildenafil does not have a cumulative effect, which means that the active substance is not accumulated in the tissues of your penis even if you take it daily. Thus, you will not have better or constant erections just because you ingested more Sildenafil “in advance”.

Sildenafil/Viagra just does not work that way.

How to store sildenafil
