Pfizer Viagra Review

What’s Viagra’s history?

Viagra, an erectile dysfunction medication, was approved by the Food and Drug Administration (FDA) on March 27, 1998 for usage to treat this medical condition. The chemical name is Sildenafil and is an artificial compound that was originally studied and synthesized to treat a form of cardiovascular disease called angina pectoris and hypertension, which is the medical term for high blood pressure.

The chemists at Pfizer, a pharmaceutical company, had discovered that it had little effect on angina pectoris but it could induce penile erections, which typically happened within thirty to sixty minutes. Pfizer saw the economic opportunity in such a biochemical effect that they decided to market the medication for impotence.

In 1996 Sildenafil was patented and two years later it was approved by the FDA. The new clinical name for impotence was “erectile dysfunction.” The name for generic Viagra is Sildenafil Citrate.

How does Viagra work?

Viagra works by relaxing the muscles that are found in the walls of blood vessels. It then increases the blood flow to particular areas of your body. Just taking the pill will not cause an erection to occur because to work you have to have some sexual stimulation.

What are the side effects?

Not everyone will experience side effects from taking Viagra but some of the general side effects include:

  • Headache
  • Stuffy nose
  • Upset stomach
  • Flushing, which can be a tingling feeling, warmth, or redness
  • Light dizziness
  • Back or muscle pain
  • Abnormal vision like changes in color vision or blurred vision

Symptoms of an allergic reaction can include:

  • Difficulty breathing
  • Develop hives
  • Your throat, lips, face, or tongue start to swell

Your physician should be called at once if you start to experience all of these side effects.

  • Sudden hearing loss or ringing in your ears
  • Irregular heartbeat
  • Experiencing a shortness of breath
  • A light-headed feeling as if you might pass out
  • Seizure or convulsions
  • Swelling in your ankles, feet, or hands

If, during sexual activity you start to have these symptoms stop and call your physician right away as you could be having serious, and possibly life threatening side effects.

  • Dizziness
  • Nausea
  • Have numbness, tingling, or pain in your jaw, chest, neck or arms that could be signs of a heart attack
  • Vision changes or sudden loss of vision as Viagra can decrease the blood flow to your optic nerve
  • If your erection lasts longer than four hours or is painful see emergency medical attention because a prolonged erection can damage your penis.

How long does Viagra last?

There is no particular time limit on how long it lasts but it should be less than four hours

What is the dosage?

The dosage is based on your response to treatment, any other medications you are taking, and your medical condition. The standard dosage is 50 milligrams.

Does Viagra work and have effective results?

Benefits of buying Viagra online instead of local pharmacy

There are many different benefits of buying Viagra online instead of at your local pharmacy and the benefits will vary from person to person. Some of the benefits can include:

  • It is more discreet because many men do not want to admit they have erectile dysfunction so they prefer to order online instead of taking it to their regular pharmacy.
  • It could be embarrassing to take it to a pharmacy and have a woman pharmacist fill the prescription.
  • It is cheaper to purchase online and in some cases you can save as much as 70%
  • Online you can get a full prescription or as few as ten pills

Conclusion and editor review

Viagra is one of the first erectile dysfunction medications to be discovered, patented, and approved by the FDA.
