Impotence is defined as the inability to achieve or maintain an erection that allows men to have satisfactory sexual intercourse. It is common to have temporary impotence at some point of time in life due to work related stress or fatigue. However, if it becomes a constant problem, then it can give sleepless nights to men. It may also cause strain in relationships.

Impotence treatment has become easy for men after the approval of Viagra. While there were remedies available for impotence treatment in the past, Viagra brought something new and unprecedented.

About Viagra

Viagra is an impotence treatment drug, which is available only on prescription and is licensed for use in many countries worldwide. It is manufactured by Pfizer. In its very first year in the market, Viagra sales exceeded expectations and set new records.

How it works?

Viagra contains sildenafil as the main ingredient, which works in the body to increase blood circulation in the penis and its surrounding areas. The arteries of the penis, which help in blood circulation, get relaxed due to effects of Viagra. Regular supply of blood to the penis results in a better erection. However, erection occurs only under the influence of sexual stimulation.

What is its right dosage?

As Viagra is a prescription medicine, only your doctor can tell you about its right dosage. It is available in tablet form in dosages of 25mg, 50mg, and 100mg. If you take a higher dose than recommended, it may lead to some adverse reactions in the body. Therefore, it is always better to stick to medical guidance while taking Viagra.

The effects of one dosage of Viagra last for about four hours and it should be taken about thirty minutes before the start of sexual activity. You should take it on an empty stomach for best results.

Are there any side effects of Viagra?

Like all prescription drugs, this impotence treatment drug also causes certain side effects. The most common side effects of Viagra are headache, facial flushing, and upset stomach. Blurred vision and sensitivity to light are some other side effects associated with Viagra side effects; however, these are very rare. Some men may also experience muscle pain after completing sexual activity.

One of the rarest side effects of Viagra is priapism, which is continuous erection for more than four hours. In such a situation, immediate medical help should be sought to avoid damage to penis. If you experience any major discomfort after taking Viagra, then you should consult your doctor.

Is it available online?

Viagra is available online. You need to do an online consultation, which is a process similar to doing a consultation with your GP, but can not replace it. You can obtain a prescription online from any licensed online clinic after filling in an online questionnaire.

Advantages of Viagra over Cialis and Levitra

Viagra has been around for more than a decade now, but its popularity has never receded. Despite the approval of some new prescription impotence treatment drugs such as Cialis and Levitra, Viagra’s popularity is unabated. This is mainly due to its fewer side effects compared to these other drugs. Viagra is also easy to take and has become a trusted name for men with impotence problems as it was the sole medication available for impotence treatment nearly five years.
