Erectile Dysfunction Drugs
According to some reports, over 50 million men in the U.S. may suffer from some measure of erectile dysfunction, a condition that can be detrimental to relationships and even mental health. Since the introduction of the first ED drug, Viagra, in 1999, ED drugs have grown to dominate the pharmaceutical market. By its manufacturer's own estimate, nine Viagra pills are dispensed every minute in the U.S.
Viagra linked to Vision Loss
Viagra is the most popular pill in the U.S., according to its manufacturer, Pfizer, Inc. Viagra has long been known to cause visual side effects and has now been linked to NAION, a “stroke of the eye” that causes permanent loss of vision.
NAION from ED drugs
NAION results from a sudden loss of blood flow to the optic nerve at the back of the eye. Usually linked to cataracts or macular degeneration, NAION has occurred in 43 cases of men taking Viagra, Cialis or Levitra for ED. In all cases it has resulted in permanent vision loss.
