In October 2007 the Food & Drug Administration (FDA) requested for changes to be made to the label of viagra. The modification, which included warnings about sudden hearing loss associated with the use of the drug, was necessitated after the FDA had received 29 reports of patients who experienced such loss within hours to two days of taking real Viagra tablets.
Because the majority of men who buy viagra online safely are older, it is not uncommon for this patient population to experience loss of hearing. However, this is usually a gradual process, and sudden loss of hearing is uncommon. The FDA reported that the sudden loss of hearing associated with Viagra was accompanied by tinnitus, a ringing or roaring in the ear, usually caused by damage to the hair cells of the inner ear, and dizziness. The 29 cases reported involved hearing loss in one ear, while a third of these cases were temporary.
During the testing for Viagra’s pre-approval, there were reported cases of hearing loss. And this prompted a one-word mention of “deafness” as a potential side effect on the former Viagra label. In contrast, any one who buys Viagra cheap does so with the very high likelihood of seeing the new warning on sudden hearing loss being included in both the “Adverse Reactions” and “Precautions” sections of the label. What this implies is that the “Precautions” and the “Adverse Reactions” sections now carry instructions that advise doctors to warn their patients of the possibility of hearing loss respectively.
Loss of Vision through Viagra
US researchers, in a recent study, mentioned seven patients who developed nonarteritic ischemic optic neuropathy (NAION), after taking Viagra, the citrate salt of Sildenafil, for their erectile problems. The seven reported cases of NAION, an eye ailment that can result in permanent vision loss, when combined with past reports bring to 14 the total number of such cases.
According to the co-author of the study, Dr. Howard D. Pomeranz, it had been known that a number of men who take Viagra will experience short-term color changes in their vision, seeing things as either green or blue. All the patients developed symptoms within 24 hours after using Viagra, with the exception of one patient whose symptoms began 24 to 36 hours after using the drug. The initial symptoms were blurred vision and some degree of vision loss in all the patients. Also, all the patients were affected in one eye, except for one of them who had both eyes affected. Because three patients already had eye problems prior to taking best Viagra tablets, it was possible that their conditions might have increased their risk of developing NAION.
The world's largest maker of drug, Pfizer Inc., asserted that it was likely for U.S. regulators to require a label that warns that real Viagra tablets have been linked to reports of blindness and vision loss in at least one in a million of people who use the magic blue pills. The Food and Drug Administration has received 38 reports of the blindness among users of best Viagra tablets. And Pfizer has been discussing with the US Food and Drug Administration about including the disclosure to the label of Viagra to clearly inform the public about the rare cases of the drug causing blindness among its users.
For anyone who has taken Viagra tablets online, and develops NAION or other side effects, a form for a free case evaluation by a qualified drug side effects attorney is usually given out to the person to fill out.
Also, the warnings about such side effects as NAION and erections that last more than four hours, are the same for the three popular PDE 5 anti-impotence drugs.

viagra, as the most popular erectile dysfunction, has witnessed a sea change in the area of internet availability. Though meant as a prescription drug, the internet revolution means that the drug is now available to anyone who wants to buy Viagra cheap online. However, this practice is strongly advised against because it has increased massively the number of people who buy viagra online without prescription, which in itself is dangerous. As the popularity of the drug continues to soar, and more people jump on the Viagra bandwagon, more reports are emanating that the drug can cause damages of more permanent proportions. Not too long ago in Washington, the Food and Drug Administration disclosed that it was having discussions with the manufacturers of the three well-known oral erectile dysfunction treatments – Viagra, Cialis, and Levitra. This is in connection with the duty of the manufacturers to educate the public on the rare cases of varying degrees of loss of vision – including blindness – that could be engendered by their products. This education is to be conveyed via the messages in their labels, and there was a report that the FDA was probing incidents of blindness among dozens of men who had used Viagra, while seizing the opportunity to caution that there could be a connection between the illnesses that could lead to impotence and loss of sight. In what could be considered as an obvious progress in the discussion, the manufacturer of Cialis has added a one-line caveat to its label.
The issue on the front burner is the sudden loss of vision when there is a block in the supply of blood to the optic nerve, which could result in a condition known as non-arteritic anterior ischemic optic neuropathy, commonly NAION. According to the spokeswoman for FDA, the regulatory body has 43 reported cases of NIAON among the erectile dysfunction treatment users, of which 38 cases are for Viagra, one for Levitra and 4 for Cialis. The Viagra number is rare, going by the over twenty million users of Viagra, if the words of Pfizer, Viagra maker, are to be considered. Complicating this issue further is the fact that NAION is seen as a leading cause of loss of vision in the older population, with statistics suggesting that cases are between 6,000 and 1,000.
Nevertheless, Cruzan was of the opinion that the reported incidents of vision loss from the use of these drugs are to be taken seriously. This opinion is coming on the backdrop of the criticism levelled in the way of federal regulators and the drug industry regarding their actions in the assurance of safety of drugs already in the market. There has been mounting pressure on the FDA to investigate the reported side effects because Merck and CO. has had to pull its pain reliever drug, Vioxx, out of the market since it was discovered that the drug had the capacity to trigger fatal heart conditions.
A lot of money is involved here. The manufacturer of Viagra, in its recent quarterly filing with the Securities and Exchange Commission, said that the sale of Viagra rose 5 percent to 438 million dollars, in the first quarter of the year. The blindness cases, however, brought a downturn in business for Pfizer, with its share losing 55 cents on the New York Stock Exchange.
Original Viagra tablets, best-selling pills that brought about a revolution in the treatment of ED, are however not sold without serious warnings. Coming with the pack is the express warning that the drug is not to be used by men who are on any form of nitrate prescriptions, and men who already have heart problems and whose doctors had warned that sex could be physically exerting for them.
