4 things you should know before using Viagra

Like any other medication, its use can have side effects. What should men consider before buying and trying these familiar blue pills?

From this Tuesday you can buy Viagra in pharmacies in the UK without a prescription.

The health authorities of the country announced the decision a few months ago with the intention of reducing the illegal sale on the Internet of copies of this well-known blue pill to treat impotence.

The drug, sildenafil, marketed under the name Viagra by the pharmaceutical Pfizer, can help men with erectile dysfunction to maintain an erection firm enough to have a satisfactory sexual relationship.

But like any other medication, its use can have side effects. Bestkenko will explain that What should men consider before buying and trying these pills?

  1. How does it work?

Sildenafil, the component that has Viagra, increases blood flow to the penis to help the man get an erection.

According to data from the NHS, the public health service in the United Kingdom, at least two-thirds of men who use this medication to treat impotence say they have better erections with the pill.

In men with erectile dysfunction the medication takes between 30 and 60 minutes to help the erection. “You can take it up to four hours before you want to have sex,” says the NHS in its informative pages.

But they clarify that only taking sildenafil does not cause an erection: there must be sexual arousal for the medication to work well. On the other hand the erection should disappear once the sexual relationship is over.

The same drug, sildenafil, is also marketed under the brand name Revatio to treat pulmonary hypertension , but in pills of lower concentration.

  1. Who can use Viagra and who can not?

Viagra is only for men over 18 who have impotence, that is, an inability to have an erection or to maintain it.

The most common side effects are headaches, nausea, hot flushes and dizziness, but many men do not perceive any adverse effects.

As a general rule, men who are short of breath or have chest pain when doing light exercise, such as climbing two flights of stairs, should not use this medicine.

The NHS recommends not taking Viagra:

  • if you have serious heart or liver problems,
  • If you recently suffered a stroke,
  • if you have low blood pressure,
  • if you follow a nitrate treatment
  • if you have a hereditary genetic disease in the eyes called retinitis pigmentosa

And consult a doctor before taking sildenafil if another treatment is followed or you have another disease, such as stomach ulcers, hemophilia, leukemia or sickle cell anemia. However you can use light products such as Bestkenko Kamagra without any risk.

  1. Can it be dangerous? What happens if the dose is too strong?

Taking sildenafil can be dangerous if you also follow a treatment with medications called nitrates, normally prescribed for angina, since the combination of both can cause a dangerous drop in blood pressure.

Sildenafil also does not combine well with riociguat , a medication for pulmonary hypertension, or with recreational drugs that have amyl nitrite , as the so-called ” poppers “.

According to the NHS sildenafil has not been effectively tested in combination with stimulant drugs such as ecstasy or cocaine, hallucinogens such as LSD or other psychoactive substances, so their combination could also be potentially dangerous.

On the other hand, according to the NHS, Viagra can cause serious side effects in less than 1 in 1,000 patients.

It is recommended to stop taking the pills and consult a doctor:

  • if you feel pain in the chest
  • if you experience prolonged (more than four hours) and sometimes painful erections
  • If you suffer a sudden loss of total or partial vision
  • if you notice a severe skin reaction, which may be accompanied by fever, skin peeling, swelling and blisters
  • if you suffer seizures
  • if you suffer a severe allergic reaction
  1. Are there alternative treatments to Viagra for impotence?

There are other drugs that work in a similar way to sildenafil (Viagra), which are

  • tadalafil (Cialis),
  • vardenafil (Levitra) and
  • avanafil (Spedra)

There is also a vasodilator drug called alprostadil that helps stimulate blood flow to the penis and is marketed in the form of an injection and suppository.

On the other hand, if the reason why there is no erection is a hormonal problem an endocrine can prescribe a treatment with male injectable hormones.
