Viagra, which is also called sildenefil citrate, is a drug used for treating male impotence or erectile dysfunction and pulmonary arterial hypertension (PAH). This product was developed and being sold by the pharmaceutical company Pfizer. It is also being sold by other pharmaceutical companies as Revatio, Cialis (tadalafil), and Levitra (vardenafil).

Though these products promised that it can cure ED and PAH, there are also various health risks involved in the consumption of it. First of all are the contraindications it has including:

• When taking nitric oxide donors, organic nitrites and nitrates, such as glyceryl trinitrate (nitroglycerin), sodium nitroprusside, amyl nitrite ("poppers")
• In men for whom sexual intercourse is inadvisable due to cardiovascular risk factors
• Severe hepatic impairment (decreased liver function)
• Severe impairment in renal function
• Hypotension (low blood pressure)
• Recent stroke or heart attack
• Hereditary degenerative retinal disorders (including genetic disorders of retinal phosphodiesterases)

Also, taking these product may also have different side effects such as:

• sneezing
• headache
• flushing
• dyspepsia
• cardiac palpitation
• photophobia

More serious side effects of taking Viagra includes:

• priapism
• severe hypotension
• myocardial infarction
• ventricular arrhythmias
• stroke
• increased intraocular pressure

Men taking protease inhibitors in treating their HIV infections should cautiously use sildenafil citrate, because protease inhibitors inhibit the body's metabolism of sildenafil, so multiplying the sildenafil level in the blood plasma, thereby increasing the possible incidence and severity of side-effects. Men using protease inhibitors should limit using sildenafil to no more than one 25mg dose every 48 hours.

Some sildenafil users have complained of cyanopsia, blue-tinted eyesight. Some complained of blurred vision and decreased peripheral vision. In May of 2005, the U.S. Food and Drug Administration found that sildenafil use might cause impaired eyesight, moreover, some studies have linked sildenafil use with nonarteritic anterior ischemic optic neuropathy.

In October 2007, the FDA announced that all PDE5 inhibitors — including sildenafil — require more prominent warning of the potential risk of sudden deafness, learned from post-marketing reports citing deafness associated with using PDE5 inhibitors.

When sildenafil citrate is used while also taking an alpha blocker, hypotension might occur, but sudden low blood pressure does not occur if the doses (tablets) are consumed at an inter-dose interval of at least four hours.
