Viagra (sildenafil citrate) is perhaps the most widely-recognized oral medication for erectile dysfunction in the world. Launched in 1998, in many areas Viagra is now considered the gold standard treatment for male impotence.

Erectile dysfunction impacts countless men worldwide. Once prevalent mostly among aging men, in modern times the condition frequently affects many youthful males as well. Erection problems often lead to dejection and stress in all aspects of life, not just the bedroom.

Myths & Misinformation:

Misinformation about Viagra abounds. In reality, Viagra is a relatively simple treatment which millions of men rely on to achieve and sustain an erection firm enough for intercourse:

• In simple terms Viagra relaxes muscles in the penis, improving blood flow so an erection can develop.
  
• An erection will not occur without sexual stimulation.
  
• After stimulation stops, blood will leave the penis and it will become flaccid again.
• Viagra is not an aphrodisiac -- it does not increase sexual desire.
  
• It has no impact on fertility, though it may aid ejaculation in men who have difficulty doing so.
  
• It is not possible to buy Viagra without a prescription; such offers should be viewed with suspicion.
  

If taken according to doctor instructions, Viagra is a very safe medication. Almost all severe side effects have resulted from taking more than the prescribed dose or using Viagra when pre-existing physical or medical conditions indicated use was unwise.

Using Viagra to Restore Intimacy:

Ideally a dose of Viagra is taken about 30 to 45 minutes before intimacy is anticipated. The medication peaks around 2 hours after taking a pill, after which effects begin to slowly wear off. Effects will be completely gone after 5 or 6 hours.

Tablets are available in dosage strengths ranging from 25 mg to 100 mg. Elderly patients or those with certain health conditions are often started on lower doses, which may be raised if effects are inadequate. 

Viagra should be used only once in a 24 hour period. Taking more than the prescribed dose can lead to dangerous side effects. Patients on lower doses for health reasons may also be advised to use the medication less frequently; once every 48 hours instead of every 24.

Precautions & Side Effects:

Certain physical conditions and prescription medications increase the risks of experiencing dangerous side effects while taking Viagra:

• It may cause a dangerous drop in blood pressure if used with medications containing nitrates. Many treatments for chest pains and heart disorders contain nitrates; it is also found in some recreational drugs.
  
• It may cause complications in any patient who has had a recent heart attack or stroke, has coronary artery disease, heart, liver or kidney disease, or congestive heart failure.
  
• It should be used with caution in patients with blood cell or bleeding disorders, such as hemophilia, sickle cell anemia, or leukemia.
  
• It may cause complications in patients with penile implants or penis deformities.
  
• It should not be used by patients with severe liver or kidney failure.
  
• It should not be used by patients who are advised to avoid intercourse for health reasons.
  

In rare cases the medication has caused vision impairment. Usually effects are transient and include blurred vision, light sensitivity and seeing a blue tint. Even more rarely hearing impairment has occurred.
