What are the disadvantages of Viagra?
In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, dyspepsia, nasal congestion and impaired vision, including photophobia and blurred vision.Some sildenafil users have complained of seeing everything tinted blue (cyanopsia). Some complained of blurriness and loss of peripheral vision. In July 2005, the U.S. Food and Drug Administration found that sildenafil could lead to vision impairment in rare cases and a number of studies have linked sildenafil use with nonarteritic anterior ischemic optic neuropathy. Rare but serious adverse effects found through postmarketing surveillance include priapism, severe hypotension, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure and sudden hearing loss.As a result of these postmarketing reports, in October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss.

Opens up capillaries that increase blood flow to the penis.
Viagra is only available on Prescription from your Doctor
Viagra will increase blood flow to the penis, thus causing it to become erect.
Here are answers, and opinions, from a variety of WikiAnswer contributors: . Contact your doctor. They will be able to determine if it could help you, and be able to inf…orm you of the drawbacks including any potential side effects, and then write you a prescription if it is needed. . At any drug store. But you need a prescription, so you need to see a doctor first. . In my opinion, everyone wants something for nothing. The world just doesn't work that way. There is only 1 manufacture of the TRUE Viagra, and that is Pfizer Pharmaceuticals. When Pfizer first released the popular love drug to the market, they were selling it at over $10 per pill. This is still true today. I don't understand how people can be fooled by all the fake types of Viagra out there. There are 2 major types of FAKE Viagra being sold on the market today. Generic Viagra and Herbal Viagra... Neither of these have the efficacy of the real Viagra, and many of them are downright dangerous. People are making millions off selling these fake Viagra medications as the real thing. If you see Viagra at $1.50 or $2.00 a pill, YOU KNOW IT CAN'T BE THE REAL DRUG. A big hint is that Drugstore and CVS/Pharmacy are selling the true Viagra at over $16 per/pill. So how in the world can these no name tiny online Pharmacies sell the true Viagra for so much less. Both Drugstor and CVS/Pharmacy will ask for your prescription information as well as your doctors contact info. . In my opinion, though I agree with most of the above answert (Viagra does cost around $16 per pill, and there are not, currently, any TRUE generic alternatives to it), I have to take issue with something. Once Pfizer's patent expires, and generic versions of Viagra become available, the generic versions WILL, in fact, be much cheaper than the "real" thing, and at the same time be just as effective. And the companies making the generic versions will be able to do so much more cheaply because Pfizer DID ALL THE WORK that went into creating the medicine. The generic makers will have no expenses other than simple production. No research and development, no testing, no regulatory. And most importantly, the generic makers will not have to apply the cost of 10,000 OTHER drugs that never made it to the general public to the price of their generic Viagra. Pfizer's patents will begin expiring as early as this year in some countries, and will be expired in all countries by 2013. So expect to see REAL generic alternatives to Viagra soon. . It is always good to buy original Viagra because it does not give late side effect like other fake one and requires prescription which shows the genuine need of Viagra drugs rather than abusing it. It is wrong that generic version doesn't work like real one. Generic does the same work like brand one but its safety is yet to be proven and it has high chance of showing late side effect. If someone is selling real Viagra, then he should ask for prescription and doctor's info.
