What Is Viagra?

Viagra is a tablet used to treat erectile dysfunction. It helps most men with sexual issues to achieve erection and keep it along with sexual arousal. Viagra refers to pharmacotherapeutic group “means for the treatment of erectile dysfunction - phosphodiesterase inhibitors PDE5”. You will not get an erection if you just take this drug. Viagra will help a man with erectile dysfunction to reach erection only if he is sexually aroused.

What Happens with Organism during Sex?

When a man is sexually aroused, blood enters penis in a bigger volume than usual. This process increases penis and makes it firmer. This condition is called erection. After sexual intercourse, this excessive rush of blood to penis ceases. The erection disappears. If erection continues for a long time (more than 6 hours), this condition can irreversibly damage your penis. You should immediately consult a doctor if you have an erection that does not disappear for a long period of time (more than 4 hours).

Some diseases and taking a number of drugs disrupt the process of natural occurrence of erection. In these cases, blood circulation in penis is inadequate. Therefore, a man cannot achieve full erection. If this condition occurs frequently and repeatedly, it is called erectile dysfunction.

During sexual intercourse, your heart works more intensively. Therefore, people who have cardiac problems are not recommended to have sexual activity. Before you start treating erectile dysfunction by using any method, ask your doctor if your heart is healthy enough to suffer physical stress during sex. If you feel chest pain, dizziness, or nausea during sex, stop them and immediately inform your doctor about any health problems that you have.

Why Apply Viagra?

Viagra enables many men with erectile dysfunction to get a natural reaction to sexual arousal. When a man is sexually aroused, Viagra helps to improve blood supply to penis, allows him to fill it up with blood quite enough to cause erection. After the end of sexual act, erection disappears.

    Probable Side-Effects

    As with all medicines, Viagra can cause some side-effects. Generally, these effects are mild or moderate and last no more than a few hours. Some of these side-effects are likely to occur when taken at higher doses. The most common side-effects of Viagra are headache, redness of the face, indigestion. Less common were such side-effects such as impairment in color vision (such as the inability to distinguish between blue and green objects or vision of all objects with a shade of blue); sensitivity of eyes to light; blurry vision; cardiopalmus; nasal congestion; stomach upset.

    When using Viagra in doses exceeding recommended ones, undesirable phenomena were similar to those mentioned above, but were usually more common. There were also reports of the development of such side-effects as hypersensitivity reactions, including skin rash, seizures, lower blood pressure, fainting, epistaxis, vomiting. Very rarely, men taking PDE5 inhibitors (a group of drugs for the treatment of erectile dysfunction for peroral administration, including Viagra), reported a sudden decrease or loss of vision in one or both eyes.

    It is impossible to determine whether these cases were directly related to taking these medications or to the influence of other factors, such as high blood pressure or diabetes, or a combination of all factors. If you experience a sudden decrease or loss of vision, stop taking PDE5 inhibitors, including Viagra, and see a doctor immediately.

    Very rarely, men reported an erection lasting several hours. You should see a doctor immediately if you have an erection lasting more than 4 hours. If you do not immediately take any action, you can develop permanent damage to penis. It has been reported rarely about a sudden loss or decrease in hearing, sometimes accompanied by dizziness in people taking PDE5 inhibitors, including Viagra.

    It is impossible to determine whether these factors are directly related to taking PDE5 inhibitors, other diseases or other medications, other factors or a combination of factors. If you experience these symptoms, stop taking Viagra and immediately consult a doctor.
