In rare cases, temporary or permanent blindness has occurred in people taking Levitra. Viagra was introduced in 1998 and had $1.68 billion in sales last year. The impotence drug has been used by 23 million men worldwide. There are a growing number of reports of men allegedly losing their vision due to a condition called nonarteritic anterior ischemic optic neuropathy (NAION) while taking Viagra. There are also reports of intraocular pressure, retinal vascular disease and other eye complications. The drug's label currently has warnings about possible side effects involving eyesight, such as increased sensitivity to light and blurred vision. Cialis (tadalafil) is an impotence drug similar to Viagra, produced by Eli Lilly. One of the main differences between Cialis and Viagra is that Cialis may work for up to 36 hours after ingesting.
Clinical studies show that vision problems occur in less than 2 percent of individuals taking this medication, as such are considered ‘rare side effects’. Many people are wondering whether Levitra can cause loss of vision. The manufacturer explains that sudden blindness (temporary or permanent) in one or both eyes is a rarely reported side effect of Levitra. However, since vision loss occurs so infrequently, health experts are inconclusive whether it is indeed caused by Levitra, genetics, other medical condition, or other factors completely unrelated with the use of this medication. There is not much information and well controlled studies that explains how Levitra causes vision problems and blindness. However, PDE5 inhibitors such as Levitra have been associated with a condition called non-arteritic anterior ischemic optic neuropathy (NAION). This condition can lead to blindness, either temporary or permanent, in one or both eyes. Federal health officials are probing reports of blindness among dozens of men who used Viagra and other impotence drugs — but at the same time cautioning that the vision loss can be linked to the same illnesses that lead to impotence. The Food and Drug Administration disclosed Friday that it was in discussions with the makers of Viagra, Cialis and Levitra about what the labels of those drugs should say about the rare cases of varying degrees of vision loss, including blindness. The maker of Cialis already has voluntarily added a one-line mention to its label. At issue is sudden vision loss when blood flow to the optic nerve is blocked, a condition called NAION or non-arteritic anterior ischemic optic neuropathy. The FDA has 43 reports of NAION among the impotence drug users: 38 for Viagra, four for Cialis and one for Levitra, said spokeswoman Susan Cruzan. Those are rare numbers, given that Viagra alone has been used by 23 million men worldwide since its approval in 1998, according to maker Pfizer Inc. Also complicating the question: NAION is considered one of the most common causes of sudden vision loss in older Americans, and estimates suggest there are anywhere from 1,000 to 6,000 cases a year.
