Erectile dysfunction drugs to have a blindness warning
“The FDA said Friday that the vision problems are attributed to NAION, which is considered one of the most common causes of sudden vision loss in older Americans; estimates suggest there are anywhere from 1,000 to 6,000 cases a year.
Risk factors for NAION include diabetes and heart disease — two of the leading causes of impotence. For that reason, it may be impossible for the FDA to determine whether the impotence drugs contribute to vision loss.”
That is an important caveat. We may never know if there is a direct relationship between the medication and NAION.
