Viagra

Viagra was the first ever prescription treatment for impotence. It’s estimated that over 20 million men worldwide have been successfully treated by this medication. Viagra uses an active ingredient called sildenafil citrate to increase the flow of blood to your penis, making it much easier for you to achieve an erection. This medication should be taken 30 minutes before sex and can remain effective for up to four hours.

Viagra Frequently Asked Questions

What are the benefits?

Since its approval for release over ten years ago, Viagra sildenafil is estimated to have helped over 20 million men worldwide to fight the causes of impotence and enjoy a healthy sex life. When taken 30 minutes before sex, Viagra will help to increase the blood flow to your penis, much like competitor treatment Cialis, allowing you to easily achieve an erection when sexually stimulated. This will help to improve your confidence and reduce sex related stress, so you can enjoy a better sex life.

How does Viagra work?

An erection is produced by a chain of actions involving signals from the nervous system and the release of chemical messengers within the penis tissue. One of these chemical messengers is known as cyclic GMP, which causes the blood vessels in the penis to widen. It does this by relaxing a thin layer of muscle found in the blood vessel walls, allowing more blood to enter the penis, which causes the penis to become erect.

Cyclic GMP is naturally broken down by a different enzyme in the body called phosphodiesterase type 5. To make it easier for you to achieve an erection, Viagra sildenafil inhibits the action of phosphodiesterase type 5, preventing it from breaking cyclic GMP so quickly. Blood flow to the penis is then increased and you will be able to achieve a better erection.

Who is suitable to take Viagra?

Viagra sildenafil is a treatment for men over the age of 18 who suffer from impotence or erectile dysfunction on a recurrent basis. Men with the following health conditions would not be advised to take it:

  • Severe heart disorders such as unstable angina or severe heart failure
  • Recent recovery from a heart attack or stroke
  • Low blood pressure
  • Severely decreased liver function
  • Hereditary degeneration of the back of the eyeball, such as retinitis pigmentosa
  • Rare hereditary problems of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption

If you suffer from diabetes, high blood pressure, or high cholesterol, Levitra may be a more suitable treatment for you.

How do I take Viagra?

Viagra capsules come in strengths of 25mg, 50mg and 100mg, which should be swallowed whole 30-60 minutes before sex. If you are taking Viagra sildenafil for the first time, you would be advised to take the 50mg dose first. You can then lower or raise your dosage depending on how your body reacts to the medication. We recommend consulting a doctor before changing your dosage. Do not take more than one Viagra tablet within a 24 hour period.

Viagra side effects

A common side effect of Viagra sildenafil is mild to moderate headaches and facial flushing, due to the change in blood pressure it causes. But these symptoms, if you experience them, normally disappear shortly after the capsule has been ingested. Less common side effects include blurry vision, upset stomach and nasal congestion. In very rare cases, men have reported dizziness, vertigo and a sudden loss of hearing, although this affects only a very small number of users.
